This thing is absolutely incredible. I never use the remote control function, I read some poor reviews about this function. I honestly don’t think it’s needed. This vacuum could suck a golf ball through a garden hose. Don’t hesitate, buy and safe yourself a ton of time and headaches vacuuming the pool. Super easy to clean, super easy to initiate a cleaning of the pool via the app.

I use this vacuum almost daily (we get a lot of tree debris). It works a thousand times better than the vacuum that the pool company gave us! You wouldn’t believe the stuff it picks up, both large and small!!! Saves energy too because you do not use it off your pool pump! I rarely do reviews, but this thing is amazing! It’s expensive, but with every penny! I have never had a problem with the app/Wi-Fi connection and I’ve used it all summer.

I toiled about what model to purchase and eventually settled on this one and I am so glad I did! We just put in a new in-ground pool and our surrounding decking isn't finished yet, which means the area around the pool is basically one big dirt pile. When the landscapers are working, tons of dirt gets shot into the pool. I was totally skeptical that it wasn't going to do a good job. The pre-installed filters did "ok", but then I read in the manual that filter size is more for leaves and grass. The unit also comes shipped with a second set of ultra-fine filters for dirt and sand. Once I swapped the filters out (which is SUPER easy) my pool has been spotless ever since. I am very impressed. Yes, it was pricey, but 100% totally worth it. And the thing can climb completely vertical. It's actually entertaining to watch. The only negative thing I can say is that the manual drive from the app takes some getting used to because there is a bit of a delay, but still super neat.

Excellent! Love this pool cleaner. It brushes, it’s sections, it travels up the walls and on the steps. We bought this after recently building a pool. After not being able to use a vacuum for the first month, we put this in and it sucked up so much sand and grit! It is easily operable by pushing the button on the power box or using the app. I gave four stars because of the price. And I need to buy a caddy which is not included in the price of this vacuum. But, the vacuum is excellent!

This vacuum has saved us on cleaning maintenance! We run our vacuum every day to every other day with the ultra fine filters. It picks up everything from dirt to large debris like leaves. The filters are very easy to clean and have lasted all season!

I’m very happy the Naititus CC Supreme. It’s a hard working robot and it doesn’t get stuck on the drain. The duel filter baskets are easy to remove, clean and replace. I’m very please with customer service. They reply quickly and remedied my issue.

This pool vacuum works great! I first bought a Polaris and ended up sending it back and bought this Nautilus. We hardly ever have to clean it manually. I highly recommend it.

I purchased this Dolphin last April after my older one that I owned no longer worked. I used it for the 10 weeks my pool was opened. When we closed our pool I removed and cleaned the filters and stored it in my basement. I went to use it this summer and the robot would not work. I called support and they had me send the entire unit to them for repair. I love in upstate NY, so I guess there is no repair place around here. After 3 weeks of not hearing anything, I called support again to be told it was in process and I should receive an email by the end of day or the next day. Four days went by and I called again, this time they stated it was finished and would be shipped out that day or the next. I asked to speak with the repair person directly. They gave me the number and I called to find out it was my power supply and no it is not ready. They are having a supply shortage and he didn't know when I would get it back. Said it could be weeks. I then called support back and asked to speak with a supervisor. I was told they were in a meeting and I'd get a call back by the afternoon. I did not get a call and called them back. Then I was told all supervisors left for the day and I would get a call back first thing Monday morning. Again, no call came. I called midday Monday and finally got a Supervisor. I explained my situation and that now I am paying weekly to have someone vacuum my pool. She apologized for the situation and told me I needed to wait because there is a supply chain issue. I explained that is not good enough. The machine should not have broken after only one year and couldn't they lend me an older power supply. She said she would look into it and get back to me. 2 days later I received an email saying there are no power supplies available. So, the machine is really good - WHEN IT WORKS, however customer service is poor. SO before you spend $1500, realize it may not work after a year and you will be out that money because they do not have the supplies to fix them. They will also leave you hanging unless you are persistent in calling. I wasted over 3 hours with all these phone calls.

We purchased this a few weeks back. It was very easy to set up and get running out of the box, the caddy was easy as well. I don't currently use the app but plan to. It does a great job, we have slopes and walls, etc. and it gets everything. The best part is my wife and I joke about how I should go clean the pool to get ready for family or friends coming over and I begrudgingly sulk outside, drop the robot in, and press a button. I get 2+ hours back each weekend now that I don't have to spend sweating while painstakingly vacuuming. The filters are very easy to clean, hose out, and replace. The suction power is excellent, nothing is left, even small dive toys or goggles that the kids forget to grab I've found in the vacuum. One tip: I originally tried to run it from an extension cord from my shed which already has long wires running to it. The robot would not start even though it appeared as though it were powered. It must have an under voltage lock out feature of some sort. But I just plugged right into the outlet and it worked.

This unit works great, not quite as easy cleaning the two baskets as my last dolphin unit which had just one basket. But definitely many times easier to clean the baskets on this vs the bag on my first robot.

You really get what you pay for. Easy to connect to the Wi-fi, runs perfectly!

Easy to assemble and connect to wi-fi. Cleaned pool well. Doesn't get entire waterline every cycle but has made cleaning my pool simpler. Still requires some manual cleaning of pool but I have 5 trees that dump leaves in pool when wind blows and I now spend a tenth of the time cleaning them out. Only had vac for a week but so far so good.

High priced but works better than expected! We have a plaster pool so it shows everything. The Dolphin Nautilus CC Supreme is keeping it clean!!! Remote control could be better. There is a 5 second delay from phone to vacuum so once you learn that it's not too bad. I'm still able to get it to go over a few areas multiple times to get anything that was left (primarily near drain).

Update (8/12/22) Okay...First of all, apologies for not posting a follow-up to this review. I honestly had forgotten that I ever posted it. Sorry folks. After a couple of days of troubleshooting, I discovered the solution to my problem. Apparently my WiFi password was too long, (42 characters). After reducing it to 32, my Maytronics robot was suddenly able to talk to my network. Yes, I know 42 characters is an unusually long password, but in my defense, my other 30 or so wireless clients had no issues with it. If this limitation is documented in the manual, I couldn't find it. The app was no help either. So after a very rocky start, my robot has been performing exceptionally well for the last 2 years. Only maintenance has been the replacement of the climbing rings once a year. I'm almost due for new screens soon, but not quite there yet. Minor niggles would be the cord - After a 2.5hr run I have a twist or two that need tending. I also still have to brush my top step occasionally. Not big problems, but worth mentioning. All in all, I'm very pleased with my purchase and would have given it 5 stars without the WiFi hassle. Consider my 4 stars a solid 4.5. ORGINAL REVIEW: My unit will not connect to WIFI. I tried different access points and tried Android and Apple apps to try and finish the setup, but it will not connect. I called customer service and was on hold for 45 minutes. When the nice lady answered the phone and I explained what the problem was, she asked for my serial number and email address and said that she would send me a "troubleshooting tips" email so we can determine the problem. I was then put back on hold and several minutes later, I was disconnected. I called back and waited an hour on hold before giving up. (I was probably too angry at that point to carry on productive conversation anyway.) My only recourse now is to wait and see if they answer my tech support request that I submitted through their website, take a vacation day and call back again or try and set up an exchange through Amazon. The cleaner itself works great, but if you can't use the app, then you can't control the robot AT ALL. I honestly don't care about being able to steer the thing or anything fancy like that, I just want the robot to run on a schedule. Problem is, is that ALL the features are ONLY available through the app, which includes a simple cleaning schedule. There are no controls on the power supply whatsoever - just an on/off button, that's it. I don't want to come off as petty about my expectations of this product, but comon! - $1500 pool robots should not be having these issues. And locking every single control feature to an app without a backup method is just plain dumb. I should at least be able to have some fundamental control through bluetooth, (which connects fine, BTW), but apparently this robot needs to contact the mothership through WIFI before you can do anything with it. As for the handy "troubleshooting tips" email, it never arrived. I'm very disappointed with Maytronics.

First Robotic Pool Cleaner for our First In-Ground Pool. I didn't do a whole lot of searching. Needed something relatively quick. There was still sediment from the install, flagstone coping, concrete surfacing, and pool enclosure. I had vacuumed manually several times but still couldn't get everything. Enter the Supreme. I basically looked for the most expensive Pool Cleaner with Good Reviews. This was it. The Android App was easy to install and connect to the Supreme. The instructions are kind of lacking, but that's because there really isn't much to it. I was a bit confused about the "plastic protectors" that were protecting the rollers that enabled the wall climbing. The instructions made it appear that they were covering these thinner white rollers. The plastic was covering the fore and after rubber rollers. Whatever. Removed those and off I went. It came with two different filters. One with a screen mesh and another that can be best described similar to an air filter for your car or the thicker ones for your house. Since it was the first go, I used the factory installed screen mesh. Into the water via the handle, and let it settle to the bottom. I initially set it to do it's full super cleaning, but, I thought it started active weird, as it appeared it couldn't make up its mind where to go. So, I clicked stop on the app, and selected floor clean only. Away it went. 2 hours later it was done, and parked itself by the edge of the wall slightly tilted up so I could grab the handle. How nice. I was surprised how much grime it picked up. Didn't take pictures. And, it apparently got all the shavings because the next day I ran the super cleaning cycle with the ultra fine filters, and there were zero shavings but more sand, grit, and grime! Very easy to use. Rather heavy, especially pulling it out of the water full of water. I bought the Supreme here on Amazon, and I also bought the 3 year extended protection by Asurion. For $78, it seemed like a no brainer to extend the warranty to a 6th year for something that costs $1500 that you put in the water frequently. If at some point they can't fix during years 4-6, Asurion gives you your $1500 back. As others have said, definitely get the caddy. Their website says to use Universal Caddy Part Number 9996084. I found it for $124 via Google. I tried to ask the company which one, and they sent me a document that doesn't mention the Supreme. I told them that, and they said the Universal works with any machine. Whatever. Also ordered the Premium Cover and intend to keep it in the shade.

I purchased basically the same model almost 14 years ago. When I had to replace it (because of an electrical issue with my pool shed, nothing wrong with the Dolphin itself) I almost didn't purchase reading the negative (ish) reviews. This is an amazing quality product! I took it out of the box, plugged it in, downloaded the app, put it in the pool, manually drove it threw some dirty spots down in the deep end and Voil'a! Off and running! I trust that this one lasts another 14 years!

Update 7/20/2022 -- Matronics did reach out to me. Their original email responses went to spam, but later messages made it to my Gmail inbox. They gave me an RMA and the unit is in transit back to them. I'll update this review when I receive the robot back. For now, I'm changing my 1-star to 3-star and will likely give the robot 4-stars if the servicing goes well. --- Original Review --- Like others, I was hesitant to buy a $1,500 pool robot with so many complaints about breakdowns and poor customer service. I thought, what are the odds that I'll get a bad one? Well, it's six weeks later, and mine is dead. It's two weeks past Amazon's return window, so I emailed Maytronics (the manufacturer) support. So far it's been four days and no answer (not even an automated response). To be fair, it did work well when it was running, but I should have got more than 6 weeks out of my $1,500 investment. Now I'm back to manually vacuuming my pool until hopefully, the company decides to stand behind their product. Before hitting that buy button, as yourself, will it be worth it when it breaks down and you have to trash it? I should also mention that controlling the robot via the app rarely worked for me. Luckily you can start cleaning from the power supply box. If you do decide to get one of these, consider not paying extra for the "Supreme WiFi" version.

(SEE BELOW FOR UPDATE)Within 2 hours of receiving this pool cleaner and taking it out of the box, it stopped working. I would turn it on, it would turn off and light on power supply box turned red. Filters were not even close to full. My issue other than the machine not working was the lack of manual. I had to go to the website and "flip" through a digital book. For 1500 dollars you'd think there would be a physical owners manual. Even after looking through the manual AND google searching, I could find no information on what the different light colors meant, other than blue good/red bad. So other than checking filters I had no idea what to look for. Also, right of the bat it would not connect to the WIFI. I tried on 2.4 and 5. I get that there are defective products from time to time and when I called the number on their website the lady was very nice but I really wish they would have sent me a brand new cleaner seeing as this one was broken right from the start but instead I have to send this one to them for a repair attempt. After paying this much and it not working out of the box they should have sent a new one. I'll see how the repair goes and update this review if it works. If not then I'll be getting my money back and choosing a different product. (UPDATE)I left my original review for comparison with this update. As i stated before, the people i spoke with about the issues stated above were VERY nice, professional and actually reached out to me after my initial review to see what exactly had happened so they could put notes in for the tech that would be looking at my cleaner when they received it. She also sent me a link that would take me straight to the owners manual for my particular machine. I was pleasantly surprised by the phone call. I explained to them in detail what had taken place, she apologized about the trouble and assured me i would hear back from them soon as their tech took a look at it. Turns out there was an issue with the motor. So in this case, i had just gotten unlucky and received a bad unit. She called me back and let me know that it could not be repaired and they had another cleaner (brand new) sent out to me within 2 days from the call. I got that cleaner in the mail this morning and right off the bat i was able to link the unit with my wifi and after letting in soak in the pool about 30 minutes, i set it to do a deep clean cycle and it set off without issue and ran the entire cycle time without incident. So far i have had zero issues or complaints as it seems to do what it is supposed to do and does a wonderful job. I would like to thank the people that helped me out with this issue and wish all companies support staff operated like they do.

This robot is a true beast of a cleaner. I had a faulty filter that’s since been replaced but left a lot of algae and debris all along the pool floor and walls. Once I put my new Dolphin in the pool, I noticed a difference in cleanliness within 20 minutes Love the app which allows you to select various cleaning cycles, schedule daily/weekly cleaning, allows for manual cleaning and finally, provides a cleaning update (e.g. 24% clean). Love the extra long cord and its anti-tangle capability as well. I don’t have to do anything but drop this baby in the pool and let it get to work. Super pumped over this purchase!

I rarely write reviews but this product is so impressive I'm compelled to give it the praise it deserves. As a retired engineer, I'm totally impressed with the level of engineering and development required in bringing this product to market. First class product..first class company. Not a lot of products live up to the marketing hype out there. This product is by far an exception. Yes, it does cost more than most pool cleaners but you get your moneys worth on this one. Exceptionally well engineered and very easy to operate. The Bluetooth and Wi-Fi connectivity works flawlessly. People complaining about connectivity issues obviously are not using up to date routing and internet connectivity products on there home networks. I highly recommend this complete package with the caddy to transport the pool cleaner. No more connecting and dragging vacuum hoses around and dealing with suction issues. Just plug it in, connect to your Wi-Fi network and drop the cleaner in the pool. It scrubs the pool surfaces and vacuums.

So I held off on writing a review on this until I had more time actually using it. Overall I love the new robot. Pros: - No tangle cord - Super easy to clean. If you have an old Aquabot with the bags, there is no comparison on how easy it is to clean the cartridges on this bot. - Relatively good at cleaning entire pool (I have 1 or 2 spots for some reason that it just keeps skipping) Cons: - The app is wonky. When it works, it works great. However, on start up this season, it just refused to connect to the robot. Then suddenly it started connecting and worked great. - The Caddy really should be included for free in the top model - Pricey

This is the best purchase we have made for our pool. It works great and cleaning is simple. The only issue is the app.

The instructions are a little vague but it really is quite simple. The Ap / wifi connection makes it easy to program. We have a fairly large pool near trees so there is always something to clean so i have it run regularly. Much better than the polaris unit that I had that died.

Some of the reviews caused me to pause on purchasing this Dolphin Nautilus CC Supreme Robot, but I took the plunge and ordered it. I got to tell you, I ABSOLUTELY LOVE IT!!! In the beginning I had to get my wifi figured out. You need to have the slower farther reaching frequency linked to it. (Makes perfect sense after you think about it) Which was easy once I clicked on the non 5G Band and after that I was off to the races. I love the filters they are amazing. They catch everything. Leg hair, arm hair, bugs big & small bugs. They are so easy to clean. It takes me maybe 5 minutes to clean them out well and wipe down the machine and put it away. The app is pretty easy. I'd like to see add ons in the future like more details & functionality but compared to not having it and cleaning your own pool by hand it rocks. It can be a little tricky steering it back to you but its not a big deal. I'd buy this thing again in a heart beat. People freaking out about the app are over reacting in my opinion. I've had it for 90 days or so now and its going strong with zero problems. The only sad thing is I asked my lady to pull it out of the pool once after it was done and its a little heavy & bulky wet and she scratched the side of the robot on my concrete edge. Its only cosmetic but I was bummed. So as a heads up to the rest of you that you may want to explain or expect its a two handed squating effort to safely pull it out of the pool. I set it on a floaty matt right after to let the water drain off keeping it off the concrete and pop out the filters to go clean them right after. Its not a good idea to let the junk dry out in them. Anyway I hope my review helps those of you on the fense. This thing is AWESOME!!!

I was using pentairs prowler robot. Compared to this….no comparison. This is so awesome, it picks up very fine particles like sand like the pentair can’t. I’m a pool builder, and strongly recommend this robot. It totally makes a difference you can see.

Short Version This product works as advertised, perhaps even better, and, despite some minor issues (see below), I can recommend it wholeheartedly. Long Version Our pool is along a tree line and accumulates debris like leaves and bugs. Our service people come every Wednesday, and the pool looks great once they're done, but by the time the weekend rolled around, it looked less than completely inviting. We moved into the house last year and didn't have much time to use the pool, and tended to be discouraged when we did. This year, early in the season, I researched automatic pool cleaners and decided to take the plunge despite the steep price. Months later, I can report how pleased I am. I had the device set up and the iOS app connected within 20 minutes. Using the app, I set it to start every morning at 7:30 AM, originally for 2.5 hours, and later for 3.5 hours. Every day, the pool looks clean and ready to use, with nary a trace of the debris that we'd come to expect. In the middle of summer, I only needed to clean the filters once a week, but at the start of the season, and now as fall approaches, I have to do it every other, sometimes every, day. Fortunately, it's only a minor inconvenience. Meanwhile, this device has made all the difference in the enjoyment of our pool, and I can't recommend it enough. Those Minor Issues Alas, nothing is perfect so I would be remiss if I did not mention some shortcomings. The very long cable can get twisted and the robot has no apparent way to untwist it, so I have to periodically unplug it and pull it across my yard. It would be nice if the unit could spin itself in the pool to resolve this. The app will often report that the cloud service is down, or the robot cannot be contacted, even though it is less than 20 feet from a WiFi repeater so powerful, I can pick up the signal from within the house. Usually I can either wait or force-restart the app to resolve it, but occasionally I've had to physically unplug the power supply. That's it. (I told you they were minor.)

To start I will explain the pictures. I woke up last week with a nearby wildfire which had dropped a ton of Ash into my pool. To make matters worse my power got shut off and was out for a little over two days. As soon as my power turned on I started running my pool vacuum and cleaning it out every hour or so. After two days, 1 backflush of my pool filter and about 12 times of cleaning the Nautilus my pool is looking pretty clean. As you can see in the last picture there's still some ash, but looks at much better. It's still dropping Ash but now I only have to run the pool vacuum once in the morning. I gave it five stars because if it's amazing ability to clean up a messy pool quickly. However that would mean that this pool robot was perfect, which it is not. I have found that it does okay picking up oak leaves but does not like to pick up pine needles which I have a lot of in my area. Furthermore the filters that collect the debris do not fully seal. So with fine material like ash it will drop a lot out of the filters as soon as you go to lift the Nautilus out of the water. I however pulled the Nautilus out of the water quickly and let it drain and drop the ash outside of the pool. This makes the Nautilus quite heavy because it's holding close to a gallon or so of water plus the weight of the unit... Even if you had to let it drain down in the pool and drop the debris, it will most likely collect it on the next round of running the pool vacuum. In which case will just require more cleaning of the filters. I'm sure the same thing will be true during our pollen season. But I did not have this pool vacuum when that took place. So that being said I would rate it a four and a half Stars. But keep in mind this is an amazing pool vacuum and does a great job

The app does not work when you are away from your home.

This is my second Nautilus. My first, a Dolphin Oasis Z5, would always get hung up on the pool drains so you had to keep your eye on it and move it manually when that happened. I tried a friend's Dolphin Quantum and it had the same problem. I was hesitant to order another Dolphin when mine died, but I took a chance on this model. With the third brush in the middle, it never gets stuck on a pool drain. This is the only model in my opinion that you should even consider.

This item was delivered damaged and PoolZoom did a great job getting me a shipping label and getting the new unit to me extremely fast! Thanks so much for your help with the return. I ran the robot through my mostly clean pool and it picked up a ton of silt and debris. I can tell I'm going to be happy with this purchase.

6 months later and I've had 1 issue. For some reason it doesn't show its connected to the internet via the app even though it shows connected via the unit display panel. So unplugging it fixes this. Yet that doesn't help if your away and want to remotely turn it on so I've simply installed an alexa controlled plug adapter that i can turn off power to the unit and turn it back on remotely which solves that issue. The unit itself has great suction, easy to clean and most of all, leaves my pool NOTICEABLY CLEAN in every area. It does a good job. That's all I care about. I needed Wifi in order that I can control it remotely when I'm out of town.

Easy to operate and easy to use does a fantastic job

I absolutely love this device. Although I did have a couple of issues with the remote setup in the beginning. But I was smart enough to just try adding the device back on again and wallah! Worked like a charm and has been non stop for about a month now and this thing keeps my pool the cleanest that it has ever been!! And I don’t mean just the bottom but the sides and the waterline are pristine!!!

Spent hours checks reviews and reading industry publications. Chose the Nautilus and can say it is worth the steep price. It climbs the walls, scrubs the waterline and will get on the tanning shelf if the water level is high enough. The remote app is convenient if some areas need attention.

Wonderful product! I have an OLD pool, built in the mid 60s and it doesn’t even have a traditional skimmer and basket. This fit the bill! It cleans wonderfully and it gets the tile line too. It’s powerful and well made. Worth the money: I have a small pool; approx 16-18 ft long, 6’ deep, all manual cleaning. This is a great addition

Second update: I upgraded to 5 stars after two full summers of use. We couldn’t be happier with the performance of this cleaner. To be honest, after getting a dud the first time, we thought that we would be lucky to get a year out of it. But it has exceeded our expectations. This is an update to an earlier 1 star review. We clearly got a dud unit. And I am grateful to Pool Zoom for allowing us to return the product and replace it. The new unit has none of the issues of the old one - and I’ve waited for a full summer of cleaning to confirm that. It connects to WiFi easily, cleans thoroughly, and does MUCH better at the water line. I did not have high hopes for the unit, but it exceeded our expectations. I am glad we gave it a second try. And again thank you to Pool Zoom for being so helpful. Earlier review below: We really enjoyed this product for the week it worked. Then we got the red ring of death. - There is NO helpful documentation included with the product or online. It’s shocking. - There is no support outside of m-f business hours. Email? “We will get back to you within a few days” Frankly, these Amazon reviews are the best support available. At least now I know that this is a common problem. Way too common. We bought the top of the line product hoping it would mean a good experience. We thought the brand was reliable. This is the single worst supported technology product I’ve ever come across. Do not even think about buying this unless you have the stomach for gambling and extreme patience.

Loved this. Incredibly easy to use. Easy to clean. Pool is now cleaner than it's ever been. Works as advertised. Maybe even better than advertised in terms of the end results. Still, a couple negatives: i) if you have any meaningful amount of leaves, you'll spend a lot of time taking the unit out of the pool, emptying out the leaves, and then putting it back in the pool -- that's because the filter is small, the leaves fill it up very quickly, and the machine won't continue to pick them up once the filter is full. On average, I end up emptying the filter about every 30-40 minutes of time it's in the pool; ii) don't count on the phone app working--not a big deal because you can still put it in the water and turn it off and on without the phone app, but it's a surprise that for a product this good that the phone app doesn't work very well. All in all, I'm happy with the product because it cleans so well and couldn't be easier to use, but it would be great if they could design a machine with a much larger filter for the leaves.

Makes being a pool owner so much more manageable. Quick, precise and easy. I love this thing!

Rather than write a big, long review of how great the Dolphin Nautilus CC Supreme Robotic Pool Robot Vacuum Cleaner is, let me save some time and just say "why did I wait so long to make this purchase". It does a better job than my "previously employed" pool man.

This pool vacuum was highly recommended But very disappointing. I expected more for the money.

This my third Maytronics Robot since 2009, and I repaired the first and still have it as a backup. I purchased this for the 2022 season and love the improvements made in this robot. It is very easy to clean and the internal skirts put into the collection basket keep debris from falling out when the robot is removed from the pool. Also, this robot is cleaned from the top and does not need to be flipped over for cleaning. The BIG problem with this robot is the control app. I was a radar systems engineer and I still can't get this thing to work. Maytronics has attempted to help, but it has not helped. I would love a real remote control. So, as much as I love the operation of this robot as it comes from the package, if you want to change its operation or control it in ANY way, do NOT get this robot. Also, the power supply does not operate properly when exposed to rain. It switches off my GFI outlet. How can you build a robot for an inground pool with a power supply that must be kept out of the rain?!?

Easy to assemble and set up. The app is user friendly. Love that we can set it to clean and not be home. Easy to create schedule. Cleans better than our last cleaner hands down. HIGHLY recommend. (It better last for a long time!)

Will post update when available.... (I received the unit yesterday). All feature and functions are controlled by a mobile device... there is no other remote manufactured for this unit. Every option to control the unit from times, scheduling, waterline scrubbing, enhanced cleaning, etc. require the mobile device. I was able to connect out of the box without a problem, however the "remote control" barely worked at all. I was unable to steer the unit more than a few inches before it just stopped or reversed course on its own. This morning, I was unable to connect to start a cleaning cycle. After much troubleshooting, I spoke with Maytronics support. It seems they have "pushed and update" and currently, mobile devices are not connecting to the cleaner. Without the connection, the only option is power cycling with activates the "basic" cleaning mode. I have concerns about a $1,500 unit being unstable out of the box and being reliant on Maytronics' continued support to control the most basic functions of the unit. Support is working on a solution, but they are unable to provide a date for another update. If it is not stable in the next 10 days, I will need to return while I still have the option... I am still wondering if I would be better exchanging for a Polaris.

This is worth the money. I have not had to vacuum my pool so far this year. Easy to program and easy to use! And I’m 74 yo

This robot pool vacuum works exactly as advertised. Super simple to operate. Just drop it in and turn it on via the smart phone app. Select the cleaning mode and run time and you're all done. It will notify you when it's done. Pull it out of the pool, remove the filter, rinse it off with a hose and you are all finished. So far I am VERY happy with my purchase and would definitely recommend this product to anyone thinking about purchasing a robot pool vacuum.

I've had two other types of robots and this is my first Dolphin. I've been using it all summer and it is excellent. I had a storm recently and it picked up relatively big leaves and sticks. Cleans walls and floor in my pond shaped vinyl pool very well. The cable does not kink and I really like the filter cartridges better than the old fabric diaper thing in my old robots. I like that I can set different types of coeaning modes...like wall only, floor only or ultra clean. I did go big with the wifi connected and manual drive features. Even though I typically like those types of options, the wifi and app usage is only a slight convenience probably not worth the money. The manual drive is not that responsive and cumbersome at best. I would consider another Dolphin for sure, but likely go with the one that is fundamentally the same but not pay for the wifi/remote control features.

This is my third pool robot. It is replacing a aquabot t2 turbo. My pool is about 36,000 gallons and spa. Lots of curved walls. The previous owners removed the filter suction powered automatic cleaner so I have been using pool robots as the main cleaner. I have had it for about 3 weeks and have run a cycle just about every day Pros: Fast cleaner. The nautilus supreme cc moves! It is fun to watch it speed its way across the pool bottom. Easy to clean. The filter cartridges come out and a part easy. A quick rinse off with a hose sprayer and it is ready to go back in the pool Wall climbing/waterline. Does a good job climbing the walls and sweeping the water line. It climbs all the steps and cleans them, though it might take two cycles to get all of them. Cons: The app is pretty terrible from what I can tell. It needs to connect to WiFi, and that is the problem. It needs to have a password 32 characters or less. If your password is any better than that, the app gets stuck in the connect screen and there is no way out it. You have to delete it and reinstall and then the cycle starts over. Customer support: As other people have mentioned it is not super. The app has a contact, which I bet answers through the app, but since it won’t complete the setup I have no idea. I have emailed a few times with no response, and my work hours haven’t allowed me to call yet. Cleaning: the wall climbing bumpers while they help with the climbing, they are very solid and prevent the brushes from scrubbing. If you have green algae, there will be two clean lines where the bumpers were and a lighter sweeping everywhere else. Overall. 3 stars.

I wish I had bought this sooner. Best investment ever for my pool

I was super excited to use this product, but had to return it. My pool has white plaster and some of the walls don't have much curve into the floor. This model has black plastic in the corners and sides, so the unit would scrape along the wall and leave black scuff marks along the edge. If you have light plaster, I suggest that you get a model that is white in color. Also, the "manual" mode through the app is not very good. Too much lag and not enough precision. You press a button, and nothing happens for a while, then it moves, and you let go of the button and it keeps going for a second. Not too troublesome for forward and reverse, but when you are trying to turn left or right and line it up, it is impossible. The manufacturer should make the manual mode turning 10X slower than what it is for it to be useful. Other than that, it is a very nice model with lots of features that is easy to clean.

This product works great. cleans the pool better than the old polaris sweeper. climbs the walls and cleans the water line. it picks up the fine sand that is constantly blowing in my pool. I highly recommend this .

This is an excellent pool cleaner, but I really wish it would map your pool. For the price of this cleaner one would think the mapping technology would be integrated, but it’s not. It still gets the job done, you just have to run it more often.

I purchased the dolphin 5 months ago for about $1600 thinking it is top of line and should there be any issues with the product customer service would be exceptional given the cost of this robot. For the price I paid I would not expect to have any issues with the product for a long time, however 5 months in I am getting a power supply error on the app. This is the second issue I have had, however the first issue was resolved after deleting and re down loading the app. To me the current issue with the power supply error is a huge concern given this product is powered by electricity and used in the pool. Customer service has been very slow in responding and as of late has not responded at all to my request for a replacement unit given the price of the product and only using it for 5 months. The company has agreed to let me return it for repair, but given the price and time of ownership and issues with power supply I would expect replacement. If they replace the product with a new unit I would be happy but so far am very disappointed in the product and customer service. My recommendation as of now....keep looking for a better product from a different company that cares about the customer.

The equipment is somewhat intuitive to set up and operate. However there are no operating instructions for using the phone app. Could not figure out how to manually maneuver the sweep with the phone app and there are no operating instructions.

After a lot of research, decided to buy this unit. Received it quickly and unpacked and put it to work. - fairly efficient once you get an internet connection for the APP (the internet connection is required) which is a small challenge as pool is 15 yards away from house and internet modem is on the far side of the house. The 3rd brush does a fairly good job of scrubbing. There is no mapping feature of the pool for the supreme (not very smart) it does sometimes takes 2 cycles (5 hrs)to get the whole pool clean. Watching it, it seems that it at times it appears confused and takes 15-30 seconds to continue on the next leg. Since 2006 have been using a Blue Diamond RC robot for pool cleaning which mapped the pool and only took 1 3 hour cycle to get it all. By the way it still works great but needs new brush's. Bought this as I am afraid to take the BD RC apart being 15 years of pool cleaning and chlorine though I am reconsidering after watching this one work. Did not help with no caddy being included at the price. So this robot is ok but.......

I was extremely disappointed when I was unable to pair my device to the robot. I attempted this with 3 different Apple and Android devices and nothing worked. Maytronics customer support offered as much assistance as they could give, and concluded that the power supply must be faulty. They would have shipped me a replacement except they are all back ordered due to the supply chain chip shortages, and they have no idea when there will be more supply. My advice to others is to not bother with paying extra for the models that offer phone apps to control your robot with. I was really looking forward to using all of the premium features I paid hundreds more for with the app, so I’m now regretting purchasing this product. One other thing to keep in mind is that if your WiFi uses 5G then it will not work, as Maytronics seems to be very much behind today’s technology standards, and the device will only work on 2.4G WiFi networks. This is just one more hoop you’ll need to jump through as most everyone is using dual band routers, which might not be compatible with your dolphin robot. Otherwise as a pool cleaner, it works great. Simple to use, just drop it in the pool and turn it on, and it goes to work. You can buy models at half the price which perform just as well. Save your money and go with a basic robot without all the bells and whistles that come with a phone app. Not really worth the trouble, hassle, or price. I fully intend to return my Dolphin Nautilus Supreme back to Amazon, if my power supply replacement from Maytronics doesn’t arrive before the Amazon Returns deadline.

I had the old style pool pump suction sweeper that always did just an okay job for the first few years. Year 5 and not sure if it was the gears or what but it hardly moved. This Dolphin arrived and wow. Just plugged it in and tossed it into the pool and it went to work without even setting anything up. Watched it climb over the small 3 inch lip that starts at the down slope for the deep end and make it to the water line scrubbing the sides easily. I let it do its 2.5 hr cycle, pool spotless. The setup is bit glitchy, would not connect to wifi, restarted the app and then it seemed to work just fine. My only complaint is not about item or company...why use FED EX they are horrible, first they tried to deliver my item to an Apt ? Second when it arrived box was fairly beat up and torn. I was worried either things were missing or broken. Luckily the packaging is very cushioned and everything was okay. Should have bought this when my sweeper was dying a year ago. 06/11/21 Been over a year, the beast is still going strong! Worth every penny!

So easy to install and does a great job cleaning

I might be biased bc this was our first pool robot, but I did alot of looking online at features and reviews and settled on this guy. Likes: programmable cleaning mode, waterline scrubbing, easy to lift out of pool, set it and forget it, cord floats and doesn't tangle, intuitive wifi app. Dislikes: that might be too harsh a term, but I wish the filter compartment opened wider so I could flush out twigs and debris easier, and/or opened on top and bottom (instead of just the top) bc the water i hose into the compartment to flush it out comes right back at me. Also the filters are a little temperamental in fitting them back into place after rinsing them off. Also, a little pricey but honestly when comparing other brands,, it seems you pay for quality, longevity and reliability. Other than these few peculiarities, this bot is the new king of the pool.

Works as described. I dont know others to compare but this do works good

Unit works as advertised, but exactly 31 days after purchase (couldn’t return) the handle cracked as I was pulling it to the surface. Maytronics customer service said it was covered under warranty and would be fixed at no charge. What they failed to mention, and I didn’t realize until they sent me the RMA email, is that I had to pay to ship it to them. Not my idea of the “exceptional experience” they advertise. I’ve owned several Aquabot products, one that lasted almost 20 years. Guess I’ll see how long this one lasts but I don’t expect customer service to be of any help. Having to spend more money after spending over $1,500.00 is not what I consider good customer service.

Cleans better than the pool guy, instead of paying my pool guy I am paying to my robot. Scheduled weekly cleaning schedule, always on time, always goes above and beyond. Once i had an issue and the customer service was very helpful over email

I hesitantly purchased this unit three months ago after doing considerable research. There are many pool cleaners available and this is one of the most costly which accounted for my hesitancy. After using it two times, our pool looked great! The unit is easy to use and easy to clean. I would definitely give it a solid recommendation. i have to admit that I don't use the advanced features as much as I thought such as manual drive. In hindsight i probably would have been happy the Dolphin CC Plus at a lower cost.

love it.so easy to maintain. cleans very well. My pool is clean all the times.

So overall, this robot has performed satisfactory. The Nautilus CCplus is about half the price of this one and the main difference is the wifi connectivity which is spotty and hard to set up because in my experience you have to get the power unit in an ideal spot that gets 60% wifi strength (per customer service). Once I got that set up, the app is user friendly. My main complaint: the traction threads have already popped off a FEW times. This is annoying but easily fixed. But my question to Dolphin is: why don’t you include an error notification and alert on both the app and the power unit so owners can address the issue immediately instead of having us find out when we pull the unit out for filter cleans??? Please include this in your next software update!!! The new voice control feature is cool but I prefer a full filter indicator and hardware error notification instead. Oh and it would have been nice to have the caddy thrown in for what you are paying. I can’t believe there’s no package deal or even for an extra $100 owners get a package deal of sorts.

This is worth every penny, if it lasts as long as my previous one (7 years). I have a 33,000 gallon salt water pool and this is a beautiful beast. I love the double basket filters, easy to clean. I also like this seller. I had ordered a lower price replacement frim then after my 7 yr old dolphin died, and the $600 model was so light weight that it wouldn’t sit on the bottom of the pool... it just floated and was defective. I returned it for a full refund and decided on this more expensive model. It was shipped quickly although during covid, many things are shipping slowly.... overall a very solid purchase for my needs. My pool is in a forest and I get a lot of leaves, pollen, etc.. hoping this one lasts for years as well. I’m not using the Bluetooth feature as it jumps off while I’m wandering around the property, but it may work for others. Another plus is that it has more rollers/suction and picks up even sand and dirt.

This robot has worked great thus far. We are in the final steps of having our in-ground pool completed and so we started with a ton of construction dirt/junk in the pool. After using a borrowed robot for several days we ordered and promptly received this dolphin nautilus CC supreme. The pool went from pretty clean to very clean after just a few cycles of cleaning and was picking up the very small dirt/dust that the other robot wouldn't/couldn't. It does not get stuck on drains and it does climb our swimout ledges/seats and clean them too. It does not work on the steps (very well), and will not run on our tanning ledge (I believe it thinks it is out of the water). The filters are easy to change and clean, but that is also the most annoying part of operation. When cleaning them out, you end up with 6 pieces to clean since there are two filtering baskets and within each basket there are 2 filters plus the casing. Not a big deal really. So far, very happy with this purchase.

I’ve had the Unit for a week. So far so good, it’s terrific. Connecting to the internet was easy. Took a few minutes to sync. The network went down yesterday, and all it took was the normal resetting of the modem/router etc to get it back up and running. My set up is a decent distance from the router and there is no difficulty connecting. I’ve written about the app because there appears to be some issues in other reviews but I had none. As for the vacuum, it does the job. We have a 20x40 vinyl pool. The vacuum crawls over every inch including the walls in around 2 hours, and voila! the pool is clean. Cleaning the vacuum after is simple. So much simpler and better than the system we used for years that relied upon the pool pump for power. And a three year manufacturer warranty, plus I purchased the extended coverage for another three years. Good product and it does what it’s supposed to do.

this is a simple easy to clean awesome pool vacuum. I change the filters from the silt filters to the leaf filters as required but both always do a great job on sand and dirt. Cleaning the filters takes about 5 minutes. removing them and washing with a garden and replacing. Programing (if you want to) took me less then a 5 minutes and it is a one time programing. I clean every day at 9 am for 2.5 hours. I still use the net for the top leaves and brush just to keep the pool in great shape once a week. Its February and the pool is ready to swim. I just cant find anyone that wants to swim in 56 degree water. Well worth the money Im hoping for many years of using this cleaner.

This is the best thing I’ve purchased for my pool, hands down. There may be ones that are less expensive, but my pool has been spotless since I’ve started using it. The only real issue that I have is the track seems to come off once In a while and it’s a little bit of a pain to put back on. But I’m not sure why thats happening.

, the pool robot has done an excellent job in cleaning my pool. I am very happy with the product

Purchased this as my first pool cleaner. I’ve had it for about 4 months now and have used it a half a dozen times already. It works well and setup was very easy. It’s easy to set it in the pool and start it from your phone. I usually use the longest cycle, 3.5 hours and have it do the tile line as well. Cleaning it out is easy too and it seems to pick up a lot. No issues so far.

I bought this to replace a Nautilus Plus CC. That one had no companion app, no wifi built-in to the power supply but it worked great. It would clean my steps and tanning ledge, but occassionally wouuld get stuck on its side and i would have to rescue it. It seems with this iteration Dolphin opted to have the robot not even attempt steps. So they stay dirty, and even the 1 foot leading up to any steps is untouched. this Dolphin wants nothing to do with steps! I think i prefer it overall because it can stay in the pool for weeks and keep cleaning without fear of it toppling over. But i do find myself getting out the brush more than with the older model.

My Husband has been on Cloud 9 since I got this for him to help clean our pool. For one it is super easy to set up, is controllable from his mobile device, sets up schedule leaning times, easy to clean out the filters and the Suction is off the charts by comparison to other pool cleaners we have purchased in the past. It climbs up the walls, the steps and the shelf table so my husband hasn't had to brush the pool down in weeks.. Additionally we noticed a significant decrease in our electricity bill, since this cleaner runs from a plug and doesn't require the pool pump to run. Definitely a wonderful buy for this family. Remember you get what you pay for and we are so happy to have found this little gem.

We had a Dolphin s300i for about five years. Worked great, but the cable started to show signs of wear due to sun and chlorine. Decided to upgrade to the Nautilus CC Supreme and immediately noticed a difference. This unit seems to crawl faster, has improved suction (all debris is picked up in the first pass) and remote monitoring via WiFi (vs Bluetooth) all make for a upgraded experience. One 2.5 hour cycle leaves our large pool spotless. The two integrated filters are simple to remove and easy to clean. In this price range you should expect elevated performance, and the Nautilus CC Supreme definitely delivers. Well done, Maytronics. One minor point of frustration was that the package shipped in the original Maytronics box, but arrived with one of the integrated handles ripped out. The contents inside were exposed, but the ultimately undamaged. Unit works great, but for this amount of money I would expect the packaging to be bulletproof.

Seriously the GOAT of pool cleaners..... my pool looks better than ever and I used to have a pool maintenance contract plus my worthless always on it's side Polaris. Stupid convenient with the app on my phone. I've had to run it multiple times per day to catch up..... nice to monitor it. Small update.... all I have to do for the pool now is brush off stairs and ledges..... but that is incredibly better than walls, floor, stairs and edges and after doing that tons of debris and sand left in the pool after the Polaris would run. It is as if I never had a pool cleaner before.... I absolutely adore it. The treads have come off once, but not a big deal at all.

I love my new Dolphin CC Supreme. We’ve had it a couple months and it does everything the spec and photos show. We also got it working WiFi connected in 5 minutes out of the box, and it takes 5 minutes to clean the filters with your garden hose. It’s a wonderful pool cleaner and our pool is kept gorgeous. Get it you’ll be glad you did. I got the extended warranty in case of future issues too since it’s a high dollar item.

Suction power isn’t the greatest. I can watch the robot go along the bottom and still leave debris behind. We don’t have any trees nearby so it’s more the sand/dirt that gets left behind which to me I thought would be a no brainer and would be sucked up easily. We also have a “safety ledge” along the bottom of the pool and the robot does not clean it. I knew it wouldn’t get the top of the tanning ledge because it was too shallow but I didn’t think the ledge at the bottom of the pool would be an issue. Really wishing I would have ordered a different robot. This one does not work as well as it should for what I spent.

My wife and I just had a new pool built. We have heard horror stories of pool owners spending majority of their time cleaning pools and less time enjoying them. So we decided to invest in the nautilus. My wife and I independently researched automatic pool cleaners. Miraculously, we both arrived at the same conclusion. This is a rare feat. It is as easy to use right out of the box as the infomercial suggests. Excluding the time it took me to read the manual and set up the app, I had the nautilus in the water five minutes after taking it out of its box. We had the pool manually cleaned but there was still some debris on the pool floor. After the four hours cleaning cycle was completed, all the debris was gone. (Leaves, sand and airborne seeds). Cleaning the filter was very easy. So far, I am very impressed with this pool vac.

The Good: Excellent suction power, dual filters that catch pretty much everything. This machine is very easy to clean as well. The app works very well with WiFi and I can control from anywhere. Overall setup is quick and easy. The Bad: This unit is heavy and large. Need some strength to lift out of the water after a cleaning. It does not come with a caddy so you will have to purchase one or have the proper storage for it. Although, it is excellent with climbing the walls it doesn’t do well with my stairs or sun deck. This is something I can live with but really shouldn’t at this price point. It is also recommended in the manual that you keep it out of the water, sun and in a dry location when not cleaning. I was not happy to read that information but adjusted around it as there is a 20% restocking fee to return it in brand new condition and a 50% fee if not considered brand new condition by this seller. Just a few unknowns you should be aware of before purchasing. With all that said, the Nautilus CC Supreme is a very good overall pool cleaner.

After 17 years I had an algae issue come up in my pool. The brush feature was why I bought it. I liked how it worked removing yellow algae. My pool has many various curved corners on walls, shape of steps plus a curved connection of bottom to walls, etc. While the size of the brushes is not a perfect match to sweep all corners -angles perfectly I was more than satisfied with it performance on it first three hour run compared to my previous cleaner. It also has two sizes of filters which I can switch out. I don't think it would work as well as my previous cleaner if you have a neighbor with a lot of tree leaves falling in your pool. I kept my old cleaner and run that first when I have a leaf issue.

I really wanted to like this robot, but after about 20 hours of running the program I have to say, it just doesn't do much to the walls. I have a small pool in Florida, and it's pretty good at the bottom, and it does climb the walls, but it doesn't actually clean them. I have a standard curve from the bottom to the wall, so nothing really shocking. I'm thinking I'll send it back. For the price, I don't think I want to clean half (the harder half) of the pool. I may as well just do it all and save the money.

I've gone through 3 Aquabot Turbo's since 1997. Aquabot's were great invention but alot of repairs which were sometime so expensive it made more sense to just replace it. My last Aquabot lasted only 2 seasons. I decided to try this out. This cleans just as good, is a breeze to empty, and using the wifi app to control it and schedule it means I use it less often and have a cleaner pool. Now I leave it in and let it clean every 3 days. So far I only empty it once very 2 weeks! It keeps a clean pool looking perfect, is the reason I bought it. Lets see how it long it last, so far so good

We purchased this for our outdoor pool last May. We live in IL, so only get to use our pool a few months of the year. It started out great. I researched lots of vacuums and felt it was going to be worth it to spend the extra money on this vacuum. Boy was I wrong!! In August, it stopped working completely. The Power Source would start and then just stop after 1-2 minutes. The robot would not vacuum anything during that time. Calling customer service, they were going to charge me $200+ to ship it back to them, but after much haggling, they finally agreed to cover the shipping to their warehouse to fix the unit. That took a few weeks (which is CRAZY since it was less than 3 months old and cost over $1500. No local repair option. By the time we got it back, we used it for about 4 weeks before our pool had to close for the year. We just took it out to use it for our pool this year and it doesn't work. We plug it in, it trips the fuse every time and the power source is not working. Super Frustrated. I was nervous to purchase this, but liked the size, functions and reviews. That said- I wish I had purchased from a local store. If I knew I was going to have to pay $200+ to ship it to be repaired when it's still pretty much brand new, I definitely would not have purchased it. Such a huge rip off. We have a fiberglass pool with stairs- it doesn't clean the stairs or clean the walls (though it says it does). Not sure what we are going to do now. I have another ticket open with Maytronics, but am considering just buying another vacuum locally as I don't want to wait 4 weeks to get it back or pay $200 to ship it.

If you have a pool ….this cleaner is a must to have. EZ to use and maintain. A little pricey but well worth it.

Love the different cleaning modes. Can focus on vacuuming the bottom or scrubbing the walls and waterline or both. The wifi allows me to start the machine when I am not at home or even right before bed when I don’t want to walk outside.

Plug and play up and running in 5 mins or less. Only tried it 2 hours......so far does the job. Climbs pool walls well. Went up one set of stairs but not the top 2. So it probably won't work for the stairs. Only issue is still can't figure out how to lock the lift handle in the center position as instructions suggest for cleaning - works fine either way. Cleans sand and other debris from the bottom of pool well. Quiet and appears to have a fairly powerful suction. Purchased the cart caddy and cover also but haven't assembled that yet however the cart caddy looks like cheap plastic quality unlike the cleaner itself which seems to be made of better quality.

I have already posted a review on the unit. When trying to register it with Dolphin none of the numbers on the shipping box or the exterier of the unit were recognized . there was no warranty card in the paper work provided. Upon calling Dolphin the guy who finally answered checked all the numbers on the box and the unit and didn't recognize any of them. His only answer was get the unit out of the pool and find the number. BYE ! Not exactly the Customer Support I expected ! Now I'm worried if something really went wrong ??

This was my first pool vacuum. It is so easy to use and does a fantastic job. I definitely recommend this vacuum. It is also easy to clean and program.

This pool cleaner vacuum has been the best purchase we have had in maintaining a very clean pool. Our pool has never been cleaner and it even cut down on pool chemical purchases. We are soooo thankful we bought it.

This is my 2nd Dolphin. Right away I’ve found the tread have come off 3 times in the first dozen times I’ve run it. Anyone else had this problem? Any fix? Apparently Maytronic doesn’t have a customer service department. Just email with auto response and phone number with full voicemail box.

This pool vacuum was such a good investment. So I haven’t actually used all the functions yet. I haven’t set it up on the wifi or even used the app. However, I put him in the pool at least every other day and it’s always sparkling and crystal clear. We have a lot of oak trees nearby and it has no issues picking them up in the pool. I do rinse it down and hose the filters after every use. Definitely a worth while investment.

This is an added item for my inground pool. Initial setup took longer than I thought it would but now the connection is a breeze. Watching it clean the pool is both a bit spooky. It is natural to watch it clean the bottom of the pool but when it actually goes up the side of the pool and then breaks the water surface it almost looks like it will leave the pool. Pretty cool at night watching it work with its lights on and the outdoor and pool lights off. Incredibly happy with the way it works and how clean the pool without much effort on my part. I get to enjoy the pool more because I spend less time cleaning it.

I am extremely happy with how clean my pool is now. The only thing that I would say negatively about this is the weight of pulling it put of the water when finished. It is heavy to start with but then with the added weight of the water it makes it a bit too heavy for some people. Otherwise, I could not be happier!

I don't really think this thing is learning my pool - or else why does it always seem to end its cycle in the deep end? I have seen it spend a fair amount of time cleaning at the water line level. It seems to have some trouble getting algae off the bends at the corners at the deep end. I have to run it several times to pick up what it seems to miss, but I can scrub with a brush if necessary. It definitely has saved me time.

Not sure why a lot of the other reviews are bad. This has been an amazing machine. It has cleaned the pool better than any manual machine. The app is not great however the machine is amazing

I have owned many dolphins in the past 10 years. This one looks great and in theory I expected to be the best one but not really. It climbs walls but the problem is that it does not really clean anything. The ground it goes over the same area and it is still not clean like the old dolphins would do. Love the cord on this versus my previous dolphin, it does not tangle. The debris reservoir leaves a lot to be desired. It is small and needs to be constantly clean. Overall, i guess it is ok but if I could I would return it for an old style cleaner with a bag.

I've used a few. this is by far the simplest and easiest to use. can control from your phone. super easy to clean filters. nice that it runs on its own, not reliant on the skimmer so your pool can keep functioning while this cleans the floor and sides. climbs sidewall and steps easily. definitely recommend. everyone who sees this at my house instantly wants one.

Great product cleans pool excellent only problem I say it’s hard to connect to the Wi-Fi with the unit

Good quality. Cleans pool great. If you are swayed by the remote operation option, don’t be. Completely worthless. Takes 10 seconds to respond. By that time it’s too late.

Delivery = exceptional, received item 2 days earlier than scheduled. Setup = exceptional, simply plug and go. Wireless function = exceptional, both Wifi and Bluetooth works effortlessly. I am able to sit in my office and control the intensity, hours and area of pool of needing cleaning. Suction = cleans like a champ, walls, bottom and waterline. Programming = a breeze, choose the days and type of cleaning

Ok, I have to admit, I'm a first time pool owner, and after reading as many reviews as I could, I took the leap and bought this Pool cleaner... And WoW what an awesome little beast... (I've given her a name "The Black Pearl"). You can turn it off and on with your phone ( I have an apple), but you don't have to have a phone to use it... The pool cleaner does a great job in getting the pool clean, especially on the water line.... Like most Pool cleaners, it doesn't get the stairs super clean, or the tanning ledge... but that's ok... Overall, great little beast for keeping the pool clean...

I would like it to filter a little finer particles. Even with the optional filter it still does not filter as much as I had hope.

I did receive a power supply that was dead on arrival, but their support team had me back in business in less than a week and the robot has been doing an excellent job of keeping our pool clean.

The unit has completely died after 60 days. The problems began when it arrived and I downloaded the App. The App has 56 1-star reviews, it is horrible. 50% of the time it won't connect with the machine and when it does it fails to change the cleaning cycles or change the cleaning times. I was never able to setup daily or weekly schedules and because none of the settings would save. I also had trouble with the suction and the climbing ability. I've always believed you get what you pay for and I thought $1,600 for a poll vacuum would get me an excellent machine - I was absolutely wrong. And since there is no way to fully operate it manually (from the power unit) once the App fails it basically becomes a $1,600 boat anchor. PLEASE take a look at the "Maytronics Dolphin Plus" App before you ever consider buying this. The reviews there was give you a good idea of what you're getting yourself into.

I’ve only had the unit for a month, but so far I absolutely love it! I am going from a suction-style unit to this one and the difference in power is unbelievable. I really like the app that I can have it in a schedule and then clean in between after a windy day.

I knew I was going to buy a robotic vacuum when I had my pool installed last year, and spent a good bit of time research features and reviews. While this model is the most expensive of the Dolphin family, I think it's worth it as it cleans not only the floor, but will climb the walls as well and clean the waterline tile. I've only had it a short time, but so far, I love it!!

Likes: Easy to clean and has an app Dislikes: The app sucks and needs a lot of work. Update it and get the bugs out of it. If someone actually used the app at the company as a new customer you would spot a good portion of the bugs. It is also pricey. I think we could have spent half and got a product that cleans the pool just as well.

This is the best pool cleaner I have ever used! It's so easy to use- you just put it in the pool plug in the timer, use your smart phone, set your time and let it go! It really cleans the walls, floors, and water lines! The filter is also very easy to clean! The only dislike I have is, it is very heavy for me to pick up and pull out of the pool!

I used to have another Dolphin robotic cleaner which served me well for over 7 years before dying. That cleaner cost me more than twice less, but comparing with this one it did far less effective job. This one cleans perfectly - much better than any pool service person cleaning manually. It is not cheap, true. But with this cleaner you can definitely get away from the manual pool service and the savings will pay for the cleaner in less that a year. As to some critical reviews here: "bad apples" do happen. Exchange it or repair under warranty and enjoy.

Exceptionally effective pool cleaner, it gets the job done, leaves the pool floor and walls super clean. I had an older suction robot that drained to the main filter, this new generation cleaner is 10x more powerful and effective. I activate it every 2-3 days and that’s enough.

This is excellent. Haven’t used a pool guy all summer. Important to use all the different functions to make sure pool gets very clean. But overall it’s great! Wireless features awesome. I control everything from my phone.

Generally cleans good enough but has to make a few passes on sand. App is easy to navigate but the manual function is either too touchy or doesn’t respond. I guess they’ll be updates since this is the first model with an app. It’s heavy to remove the unit out of the water and debris does fall out from the bottom. Overall I like it better than the Polaris.

I bought this to replace a Hayward SharkVac XL that would get stuck on my main drains every 5 minutes. I’ve ran the Dolphin through my pool about 5 times now and the thing is a champ. Drives over my drains like a tank and doesn’t get stuck on my ladder. Gets the pool crystal clear every time. Even gets the dirt in all the corners, which my last robot didn’t do. The app is nice, sometimes a little difficult to connect. The manual drive is cool, although I haven’t found a need for it because the thing gets all the dirt the first time around.

We bought to replace our zodiac mx8. We have a curved pebble tech pool. This unit does have a hard time climbing the stairs and some of the curved walls but that being said is way better than the zodiac. It is way cheaper to use and it scrubs the bottom of the pool and the walls better than the other plus our main filtration system is so much cleaner due to this robot. I recomend rhis to anyone with a pool u turn ur pumps on less and let this clean up the botton and it picks up the debri and with the 2 types of included filter media it picks up the fine sand.

"Nessie", as we call him, is fantastic! It goes on its rounds peacefully, occasionally rising to the surface to scrub the water line with a gentle gurgling of bubbles. It has changed our pool owner lives for the better.

I live in Florida and the pool is under a cage, so big debris is not generally the problem. But I live on a well and there is sand in the water line. I ran the bot 3 times in the first 24 hours. The picture is of the first time and the filters were about like that after the 2/3 time. So easy to set up and use. No issues with the app. No tangling of the line. I don’t know if it will allow me to get rid of my pool service, but the pool definitely looks a lot better!

I bought this product but it was not working well. The motor was not advancing and picking up anything. I returned it. I think it was not an original one because it didn t come in its box. I wanted to know if I could ordered another one instead of being reimbursed but be sure it is a product that works and is original!

The bottom of my pool is blue again. Problem with DE leaking past filters, Dolphin cleaned it all out in 3 cycles. Arrived with some broken tabs on ultrafine filter elements, customer service had new ones at my door 3 days later! Hoping I can give the same review a couple years from now.

For anyone debating on a Dolphin Pool Cleaner 🐬 Here is all you need to see. 👀 This is the best pool cleaner I’ve ever owned or seen. This is from one week of running in a pool that already looks crystal clear. It amazes me the amount of fine particles it gets. DOLPHIN Nautilus CC Supreme

We have been using this for over a month and it is wonderful. It cleans very well and hooking it up to the Wi-Fi was a breeze. Just follow the instructions and you shouldn't have any trouble. Love the schedule mode. I would definitely buy this again.

My new best friend! We have a 10’ deep concrete pool and this things does everything it says. It is amazing to watch it climb the walls and clean the water line. They say you get what you paid for! I AGREE. This little guy is worth the money.

Dolphin is a wonder machine! Our old one hit the dust at the end of the season last year, Hubby said he needed a new one to open up! When it came in he programed it to his smart phone. It cleans our 16' x 36' inground pool (with a liner) amazing well. It saves my 72 year old husband from manually cleaning our pool for the grandchildren. Since we purchased the first one many years ago, it saves time when we are invaded by our grandchildren wanting to swim! The pool is always clean and ready!

I had this product for 2 years. Just put it back in the water today and app does not work. The cleaner works but you cannot schedule or do anything with the app it is useless. Look for another product this is ch!nese junk as usual.

Seriously amazing vacuum for the pool .... what’s the point in buying anything else! It has amazing suction picks up everything especially sand which I had a lot of after the winter. My pool is an inground 30x50 pool that was out in the end of last year 2019. So I had a lot of sand that must have come off of the pebble finish I surfaced the pool with. With that said the vacuum scooped up all of the sand after running it for 3 days for about 8 hours . Great product !!!

Wow! What a game changer. We have only used "Bob" six times, but we are very pleased with how great the pool looks. My daughter posted a pic of my grandchildren in the pool on social media. Someone commented it was the cleanest pool they ever saw. It definitely is the cleanest OUR pool has ever been. It was worth every penny if it continues to do a great job for seasons to come. We'll update this review if we encounter problems, but for now, we are impressed with its performance.

Works really well and fairly easy to use with a little tech saviness. Super easy to clean

This really frees you up to do other thing while it takes care for cleaning the pool. It works on your schedule. You don't have to wait on the pool man to enjoy a clean pool. It works on your time. If you are like me and value your spare time you wont be disappointed.

Awesome pool cleaner. The price is a bit high, but it does the job. Saves your pool filter, and takes small amount of electricity. Was amazed how much it was able to capture, and climbs the walls like a champ. Wasn't sure if the buy was worth it, but it will pay for itself over time. App was easy to use. Set up everything off the bat, and it registered the warranty during set up.

First ever pool robot, and I'm in love. This guy tackled my very dirty pool after initial open and now it is crystal clear. The wall scrubbing feature is great. The only negative is it will not go up my stairs. It goes up everything else. The app is fine, nothing great (would be nice if there were stats or mapping data like a Roomba). Would recommend this hands down. The filter types are great at getting debris and also filtering pool water.

It works, it works. Cleaned the pool. Initally had an issue with the wifi but it also works - the joy-stick has a learning curve but over time I am sure we (my wife and I) will get the hang of it. Very happy with the over-all product.

Love then unit hate the double filters! I have a lot of pine needles and leaves and they get full quick. Its a pain to have to keep taking both filters out when I wish it had just one large one

We bought this just under 1 year ago and used it last pool season. We just opened our pool for this season and ran the unit 2x. Since the last operation, the unit will no longer work. Status indicators and app suggest the power unit cannot communicate with the robot. We've been trying to reach support through phone, email, and phone app submission but have had no luck. Great unit, lousy product support thus far.

The robot does a pretty good job (not great but I saved me vacuuming most of the pool). What is very unfortunate is the software and customer support in relation to this. When the app stopped functioning I contacted Maytronics. I was a good sport and jumped through their hoops, having me reinstall the app 100 times, moving my home access point around to get better signal. I knew the entire time my WiFi wasn't the issue - the software is just horrible. I'm not nitpicking either - I used the robot for a month dealing with the unreliable connection and put up with it because the robot was helping me clean. But now it won't connect at all which makes the robot useless (no manual override). Their support has since stopped responding to me completely, 6 weeks after I bought it. I really wanted to like this robot because it does what it should. The company service is just horrible though. One other thing that customers should know - and I don't know if this was by mistake - but when dealing with their support they revealed some things about my home network that I found creepy for them to know about. The controller apparently relays all sorts of details about your home network back to them and they store it for who knows what purpose. But as a privacy concern, I think everyone should be aware of this.

So far the robot works like a dream! Oh love all the features. My only draw back is that we have a tanning ledge that is too shallow for it to work. Other than that, we love it!

I downloaded the dolphin app first only works in 2.4 ghz or less but it was super easy to set up and I definitely recommend getting the caddy because it’s heavy and it keeps all the parts together my pool was dirty because our old cleaner cord was chewed up by our dog put this in and set it for deep cleaning 3.5 hrs and right away it looks amazing I have only had it for a couple hours and so far very pleased it came with extra filters as well

Man oh man I’m glad I trusted my gut and bought this one even though this was way more than I wanted to spend. I never leave reviews but felt compelled because of the cost and a few bad reviews. It’s only been a few days but so far greatness! Super easy to unbox and get set up, no more than 20 minutes tops. If you’re on the fence about getting, I highly recommend.

Every time that I try to use it, I have to reconnect the Bluetooth connection; for starters! Customer Service is really lacking as there is always at least an hour wait. To pay the premium for the product and have such poor product support is wrong!

This new robot has all the functionality I could envision to improve upon my 12 year old Dolphin. So easy to clean, programmable and more powerful.

With the wi-fi connection, I can monitor the status while doing other activities.

The robot cleans good. However it leaves black marks on the corners and steps of pool from the plastic on the sides. The marks are extremely hard to clean off.

This is my first robot pool cleaner and the entire experience has really discouraged me from ever buying a pool robot cleaner again and any expensive high priced item from amazon . Not even within two weeks of using the brand new robot I noticed it spinning around in circles. When I went to inspect it I noticed the tread had come off one of the tracks. I contacted Maytronics and their warranty is that you pay to ship the item to their location for repair, which would be more money spent on an already expensive item. I already shelled out a small fortune for this thing and now I have to pay to get it repaired? The seller’s policy is even worse. You do not want to return this item unless you want to pay a 50% restocking fee. Your purchase is essentially final. Knowing what I know now I would never purchase a pool robot cleaner ever again. The customer service is horrendous and designed to make your purchase final and stick you with expensive repairs with their 3 year warranty.

It does everything it says it does. The only thing, it doesn’t climb stairs, but other than that it’s a great vacuum. I would highly recommend it!

After two months of very light usage, the power supply unit fails. I waited for a new one to arrive, connected it, and now the app won't recognize the robot (robot works). Now I have to mail the robot, power supply and filters to the manufacturer so they can "fix" it.

I’ll never go back to the old pre-robot days when I or my pool guys would have to suck up leaves individually. This thing is a game changer. Among other settings, it can be set to “floor only” or “floors and walls”. It won’t climb up onto my tanning ledge but that’s totally fine. I brush that off periodically and my Dolphin robot buddy takes care of everything else.

Easy to use and very effective. Cleaning could be easier though.

Took a big risk and bought this. Cost me a lot but wow, this little guy is unreal. It does walls, steps, I even found it one day doing acrobatic moves! Almost did a flip! This is worth every penny. My liner has been spotless. I haven't even used the app yet. Put him in and for a three hours tour and he cleans everything. Also the filters are super easy to clean. Totally satisfied.

It's easy to clean it's a little heavy but it does the job better than a Polaris

Bought this based on other rave reviews. No matter which filter is in the vacuum it always leaves stuff behind in the pool. Absolutely can not run it while not home (so the dream of starting the vacuum and having a nice ready to jump in pool won't actually happen) because it gets stuck on the stairs. Not only does it get stuck on the bottom step (so NO this $1500 robot will not even vacuum your stairs!) it will stay stuck for the remainder of the time to clean the pool...meaning it will sit there stuck to the curved edge of a stair for 2.5 hrs unless you move it. For $1500 I would expect a vacuum that does at least as good a job of vacuuming as I can do manually, won't get stuck on the side of a stair but would actually vacuum the stairs. UPDATE 2 yrs later: We are coming up on having this for almost 2 yrs now. At this point we are now having to replace the hose and the climbing wheels. Not sure what else we may need to replace. I really want to love this robot but with the issues we have had, lack of any response from customer service and having to replace parts with less than 2 years of ownership I absolutely do not recommend this product. Or, I at least do not recommend buying from this seller.

This is the best pool sweep I have ever purchased! I don’t use the WiFi control because my pool is situated far from the connection. I love every other feature. It climbs the walls and stairs with ease. It will not clean my beach landing because the water is too shallow.

It cleans really good. Hard to get on to the sun shelf. Manual drive is very hard. You have to completely close our app from running programs for it to reconnect on Bluetooth. Expensive but you get results for what you buy.

The media could not be loaded. Dolphin really does his job and save me a lot o time It’s easy to use and very easy to clean the filters.

This is great device and it cleaned my pool well. I cannot connect this device to my WIFI, I created the request, but got rather general answer. But it is good device.

I was using a Polaris for 4 years. This summer, I began having trouble keeping my water clear. I purchased the Dolphin, and within a few weeks, my pool was back being spectacular. I recommend this product. Plus, my electric bill is lower.

This Robot replaced a 20 year old Polaris standard pool sweeper, 20 years is a long time and it’s like night and day. The robot cleans parts of the pool and waterline untouched by old system. Very easy to clean, programmed for different cleaning functions. Would recommend this device to anyone with a pool. Very happy with purchase.

Great pool cleaner. Keeps pool clean, the Bluetooth works great. Should be careful taking out of pool can be heavy and bulky. Easy to clean.

Perfect job every time. Does lose connection to WiFi easily but usually connects back with just a reset of the app. Waterline cleaning is great and love being able to set the schedule from the app.

This robot is cleaning the pool well but unfortunately the Power Supply came with a defective Bluetooth chip. I am unable to use the app and automation features of this robot which is its main selling point to me. I have been in-contact with Maytronic's support and have tried all the troubleshooting steps they asked me to do. The device is obviously defective but the rep I was talking to has not even offered to replace the defective power supply unit. Furthermore, it takes 24 hours before they would respond to my email. Beware of quality issues when purchasing this robot.

I read so many reviews on this one as well as others and some people had horrible things to say. I have had this for about 2 months and love it. It is so easy to use with the app and cleans so well. I don't miss cleaning my pool at all!

Exceeded my expectation! We have a bee pool scrubbing it by hand daily. I almost bought one more expensive but thankful for reviews. This thing cleans so well! Set it and forget it! One month in and it has never got caught and it is much cleaner! Great product!

The black plastic rubs on the plaster leaving black lines which are very visible. I noticed other reviews saying the same thing but figured it was rare. For $1700, you’d think you wouldn’t have black lines all around your pool. I’d like to return this as it’s damaging my plaster but the seller advised me of a restocking fee and shipping charges. I DO NOT RECOMMEND this pool robot or this seller.

Great product, easy to use, don’t waste money on wireless, that part does not work. But it really cleans good.

Ordered last week after my previous Dolphin cleaner failed to work after 8 years. Did not like the price but because it has a third row of cleaners/brushes, I thought this would stop the Dolphin from getting stuck on the bottom. So far so good, and the Dolphin came 3 days earlier than expected.

I had an aquabot for more than 10 years I read about the dolphin cc supreme and it got excellent reviews so I purchased it used it for the first time. So far we ran it in the pool 4 times and the pool is still dirty. My opinion on this leaner is this is the worst cleaner on the market I do not recommend this cleaner at all. Also it comes with no manual just a quick start guide and brochures telling you how great it is!

until now it deserve the 5 start since filling our expectations on performance

The media could not be loaded. Limpia super bien y me ahorra muchas horas de trabajo. Super recomendado. Fácil de lavar después de usar.

If you’re on the fence as to whether or not this is worth it...GO FOR IT! After a recent hurricane our 20x40 pool floor was COVERED in large leaves. This thing sucked them all up in two cleanings. Absolutely unbelievable. So unbelievably happy that we purchased this.

I’ve only had this cleaner for a month. I love it. Amazing how it picks up fine particles. I would highly recommend it.

Well designed, engineered and assembled. Does a beautiful job and filter assembly cleans up easily. WiFi capability is a very nice feature A bit heavy to retrieve from pool when job is complete, helpful to let water drain out before lifting. So far we are really pleased with the all round quality.

Very impressed so far. I've been able to turn off the floor pop up to save money running the pool pump. With the filters I've only had to run the Dolphin twice on the ultimate clean setting. I am trying to find how to get the receipt from amazon to complete the warranty

Worth every penny! This version is super powerful and quick. Highly recommended.

I have it for a while now and I am pretty happy with it. It cleans very well and is easy to use. The app is giving me troubles sometimes though and I have to restart it.

Love it! Easy to assemble cart, easy to set up and put to work! Love the app and scheduling assistant

Took it out of the box, took off the shipping packaging, threw it in the deep end, plugged it in and pushed the power button. It cleaned for 3.5 hours nonstop and did an excellent job. Used it everyday since!!!

Loving this little beast so far! We've been using it for about 5 or so weeks and it's a huge time saver and allows us to skip paying for a weekly pool guy. So, it essentially pays for itself in less than a year.

Works pretty well. Cons: Doesn't clean steps well. Sometimes stops during cleaning cycle and has to be restarted.

This vacuum has great suction; is easy to clean. Best of all, the cord does not tangle.

Has the fine and large filters. Cleans walls well too and I have a natural pond curvy pool. Easy to connect to WIFI and upload warranty info on the app. Plugged it in and 2 hours latter my pool was clean!

We had a lot of pollen this spring and sediment had built up from some landscaping work we did over the winter and the pool looked horrible when I started but after several runs, the pool is cleaning up just fine. It's a great product.

Best cleaning our pool has ever had since it was brand new. Great design makes it easy to clean out the filters. I bought a cart and cover. Very happy with this robot so far.

Poor suction. It only cleans the pool that's already clean. Misses big areas of the pool. Does not clean floor corners. Only likes to stay on the deep end of the pool. Does not map the pool. Does not do steps or benches. Does not work in manual mode, keeps switching to automatic mode and crawls away from the areas I need it to clean. Manufacturer (Maytronics) is responsive, but so far none of the issues have been resolved.

Easy to use and does great job

Love everything about it. Our pool is sooo clean

Product is the real deal. Works great exactly as advertised. Worth every penny

Does an excellent job keeping the bottom and sides clean. Very powerful. Much easier to clean then older models.

This vacuum is easy to setup and use and does a great job cleaning. It is a little heavy.

The cleaner works hard so you don’t

Great Pool Cleaner

I have had this cleaner for 1-2 weeks and it has been awesome and everything as advertised. I had another brand for a few years but so far this cleaner has been superior.

I am not crazy how this machine goes its different way. It doesn’t cover the entire pool in the time allowed for it to run. I do love how this machine picks up the dirt though.

Easy to use, I purchase to be use in South America, it works perfectly with 240 volts

Best money spent

Delivery of the Nautilus CC Supreme was on-time and painless. Unboxing and setting up the cleaner was a breeze. That's about it. I am now the owner of a "cleaning challenged" $1,500 "brick". This cleaner will not clean to the waterline, leaves whole areas of the pool untouched, has no "idea" how to climb sloping sides, and requires me to "help" it clean the sides. All in all, it saves me about 15 minutes out of 2 hours scrubbing...pretty expensive helper. Maybe if you have a standard rectangular tile pool, this is the one for you. The top internet reviews should really explore this issue, and not lead people astray. I'm no different than most of the "experts". Everyone has both an opinion and a ...., nuff said. Build quality is excellent, value not so much, performance...on my pool is poor. My advice, for the price, hire a pool boy for the summer! Not a recommended buy for free form, sloped pools.

This thing is amazing. Switched from the Hayward Shark XL, and what a difference. The hose doesn’t get tangled and all the app features are awesome.

It’s so far been a great product. Every once in a while I will have to reset phone for Wifi control of device but so far so good.

I purchased Nautilus CC Supreme Robot $1543.19. The robot broke within months. They said to take to Factory Authorized Repair in town and is covered 100%. Its been 5 weeks and nothing. I called Maytronics and asked for supervisor. Supervisor never called. Talked to customer service and they cant do anything. But MAYBE had I mailed robot to them they could talk to me. The second call I made I was told parts were on backorder until who knows when. Another week and 3rd call Asked for supervisor (you never get). Customer service dept says alot of parts on backorder. Nothing he could do. Sorry. They have zero robots to replace or refund. Requested again for supervisor to call me. Nothing. Think Twice before buying.

I order new and not working so return to sender.

We just bought this robot and used it once and on the second try, the app refused to work, said wifi wasn't working or power supply too far from wifi signal which wasn't so, it was right next to it. Without the app, the robot would only clean the bottom of the pool, not the walls, etc. and these features could only be used through the app not on the machine itself. It is a great robotic cleaner if the app worked, which it doesn't, and we could not contact Maytronics customer service, telephone number always busy, Amazon couldn't help either except telling us to return it, so we are returning the robot. After the fact, I did read reviews of the app and most agree the app is terrible and doesn't work. It is a shame as the robot itself works great but certainly is not worth the money if you cannot access all its capabilities and the app does not work. So buyer beware.

malfunction in two months. need warrantee service.

Fantastic product! Pool was new and murky and milky. Took about a week to make it crystal clear.

I love how well this product vacuums and scrubs the water line with ease. Every bit of debris is picked up. Sadly this had to go back because it is made of black plastic and left horrible black marks all over our white plaster pool. They will never come out. Very sad and displeased at what destruction it left. Had to return. I guess you could only use this successfully in a black plaster pool, tile (maybe?) or fiberglass. NOT to be used on gunite.

It cleans randomly, and could be set up to clean in the "Ultra clean mode for the longest time available (3.5 hours) and machine still misses some spots. My swimming pool is only 12X25 ft, and incredibly, it will miss some spots. It also won't stored fine dust in its filters, so it is push back into the swimming pool water. Not good. On the other hand, It cleans floors, walls, and water line very good, but only the areas it actually gets. I hoped, for the price, the machine will map up all swimming pool areas, and clean it systematically, without missing any spots, like our samsung carpet cleaner does, for a third of the cost.

While they claim to have a great and industry-leading warranty, it's awful. I have been waiting for months to get a replacement power supply, that died after 3 months of use.

This cleaner is easy to use, very little set up. Does a great job, stairs and odd shapes are taken care of easly.

Works great so far

We have had several pressure-side pool cleaners. This unit puts them to shame.

Love this pool cleaner. World of difference over our old Zodiac G3.

This is my first robotic cleaner. I read many online reviews that rated this unit as a “top of the line option.” I decided to give it a go, despite the mixed reviews on Amazon. Unfortunately I didn’t get very far. Upon opening the box it became very evident that the unit was used. Paint was chipping from the handle and there were scratches and scuff marks on the body of the robotic cleaner. For $1,500 the unit should be pristine. Now I get to spend the next 2-3 weeks waiting for the item to ship back to the seller before a refund is issued and I can look for another robotic cleaner. I do not recommend the Pool Zoom seller.

Send a message to manufacturer waiting to hear back but probably going to send it back. Michael aristide and this was my second Polaris so I figured I would try this unit because it got the best reviews. I Polaris never had an issue cleaning the pool I had to wait two days so the pool got pretty dirty, but nothing the pilaris couldn't handle in 1 cleaning. no matter what I do all this thing can do is go back and forth in 4 ft increments across the bottom of the deep end can't make it to the waterline even though it's set to go to the waterline and can't even make it into the shallow ends even if I try driving it manually. Seems relatively useless, thinking of you throw it back in the box and order another Polaris.

App does not work well! Robot does not clean the pool floor and always leaves track marks

It is great and really keeps the pool very clean

Item was returned, had scratches and dirty a few places, a returned item sold to me as new.

Easy set-up. Cleans better than my pool guy did.

It quit working this august I have had it 2 yrs and it wasn’t cleaning that good this yr. so when it no longer even powered own I tried calling the number it said because I had my original receipt. I got the number had been disconnected and I even bought the extended 5 yr warranty on top of the 2 yr warranty and like always I’m screwed. If anyone knows what to do please help!

Received quickly,item as described. Will update the review after we get to use it.

So far I am really impressed. It's working very well

This should NOT be happening to a brand new pool vacuum. It won’t connect to WIFi and turns on for 10 seconds then red light appears on power supply. I have to pay $70 to ship unit to Georgia. After spending over an hour on the phone waiting for support, we learn that this company only has 15 people answering phones. The manufacturer, Matronics, says the motor and power supply was bad on a $1500 brand new vacuum. Really? We received unit back and it won’t go into ultra mode nor clean steps. Waiting on response from manufacturer. Manufacturer now says they sent wrong replacement power supply during original warranty repair. Their cloud service which controls the vacuum is down now.

Did not get cover for the dolphin.

I should have purchased this years ago.

Incredibly easy to use and does a great job

So impressed, expensive but worth every penny

Works great easy to use from your phone easy to clean

This is a really nice machine, nice phone app, nice warranty

- WiFi never connected, spoke with customer service and they suggested taking to a store. Store they suggested wanted to charge to even look at it. - two weeks later the unit itself stopped cleaning or moving. Called customer service again. After thirty minutes the pleasant woman I spoke with (she was thorough and nice) said they would send a new power supply box but it would take a week to arrive and wasn’t sure if that was the actual problem. Returning it. VERY disappointed

We love it

I am very disappointed with this product. For a robot cleaner costing more than $1500 this vacuum behaves erratically especially when cleaning walls and water line. It often gets stuck on the weir filter inlets and stairs. After cleaning 2 ft of the waterline it will suddenly stop and go back down to the bottom of the pool. While it is supposed to be a top of the line unit I have found the way this makes decisions to leave gaps in clean in corners etc. it will repeatedly clean the deeper end of the pool over and over leaving the shallow patchy in any cycle. I am seriously considering returning this product and buying a Polaris product instead

Works great, very easy to clean compared to the Polaris.

I had the unit for less than 3 months and it stopped working. I tried troubleshooting it with maytronics but they state it is likely a motor issue or the cord has stopped working. This unit is only available online and they state no local dealers will service it. They offer no other solution than to ship it back and wait for a total of up to 2 weeks with shipping time and servicing time.

did not clean top of water line, could not climb walls. I didn't want to write a review but I felt I had to. already in the mail, and yea the app stop connecting, it's the coolest thing ever, dual filters three scrubbers but could not clean all the way up the water line. Will buy another type, not sure what type yet tho. I'm thinking the step above this one with the gyro in it. I think it will be smarter.

Easy to use and cleans great

Not sure why everything in the box was either dirty or looks like refurbished. I paid full price ~ $1500 for this product. Most likely will be returning this back. I cannot comment on performance for now, unboxing and looking dirty item itself was disappointing. Uploading some of the pictures for reference.

Machine worked flawlessly for 2 years and then quit. Troubleshooted with tech support (very prompt through app) to no avail. Now have to send back for repair. Not sure about how to box it up. Luckily still has over a year left on warranty. Loved it until I don't......

Excellent!

We recently got a new pool in our yard. Since it was new, we thought we would get a high end cleaner to keep it looking new. Every time we have used it we get black scuff marks on our plaster from its casing on the walls and steps. We also have an in pool table that it constantly gets stuck behind. I have been able to remove most of the scuff marks with a magic eraser. But for this price I should not have to follow it around cleaning it's mess. The customer service has not been helpful either.

Good product

Updated review: It runs for 10 minutes then it stops and the power button turns red. I've tried cleaning the machine several times but after only a few weeks of use it's never been able to complete another cleaning. Waste of $1500! Previous review: The setup was super easy. I dropped it in the pool and it cleaned the floor and walls really well. It missed a couple leafs as it vacuumed the floor but using the app I took control of the bot and vacuumed it up effortlessly. One day down...we'll see how the next few weeks go!

Was so excited for this Robot to clean the hell out of my pool. Was equally disappointed when it didn't. I know Robot's don't get everything in the pool, but Phil, (we named him) didn't even clean 35%. For $1500 I was hoping/expecting Phil to suck up at least 90%. Thankful that Amazon made the return super easy.

This cleaner has scuffed up my plaster. Not happy considering how much this cleaner costs. It’s the body of the cleaner that has left marks on the plaster. Going to return this expensive cleaner and look for one that doesn’t have a body covers the treads like a fender.

I would give it 0 stars if there was an option. It worked great and my pool was so clean. I was so impressed. It was so easy to clean the filters. But it died into week 2. only works one side for a couple minutes then gives the red light and stops. Would not buy again.

Does not clean as advertised. The software needs to be updated, this robot cleans randomly and misses over 25% of the pool floor. Does not climb up to the waterline, no matter how you adjust the floating handle. Leaves 80% of the walls untouched.

It worked 1 time and never again. We had to return it. The Dolphin seems like it would be great if it continued to work. The manufacturer deemed it a defective product after a red ring appeared on the power supply. The customer service had nice people but did not help at all.

[See Revised update] This is my first robotic cleaner. It is a very nice cleaner and seems well built BUT it does NOT go up to the water line. I have tried various settings and nothing works. I have a 30,000 gal free form pool. It also misses spots in the pool. I tried out a cheaper dolphin demo cleaner from Pinch-a-Penny that did almost as well as this top model. I do like the three brushes though. The cleaner does a great job with the majority of the pool. It is not a lite cleaner, but is a bit heavy to get out of the pool. The Dolphin Google App the company recommend downloading is USELESS. You have to be 3 feet from the power unit for it to work!!! The cart is nice and fairly sturdy but the instructions were clearly written by someone who is challenged with the English language. I had to start tear down and start over assembling the cart. It took awhile. Revision (after the pool is cleaner): I'm using the cleaner for about the 4th time today. It is going up on the waterline (at least in the shallow end). The cell app is working a lot better. It's as if it updated or something because there are functions that didn't appear before. One of the functions I particularly liked was the manual drive to get a couple of spots the cleaner missed. It is really getting the pool clean.

don't be a fool like me, be aware that if you return this item for whatever reason (even if its still new, never opened and in box like my case) they gonna keep 20% of the paid price, meaning I've lost $325! Just a shame!

Didn’t work at all ..sent back weeks ago waiting for refund

I have had for 10 days and still not able to get account activated and machine running.

Will not climb walls of a fiberglass pool. Will not clean the steps.

This item was clearly used and/or refurbished. Avoid buying from here.

Unable to connect to internet. Contacted the manufacturer they have not been helpful. Unfortunately, did not get to experience how it cleans since unable to set it up.

This robot broke during the first use. One of the bottom rollers came off and out of the track. I do not recommend purchasing the product.

The media could not be loaded. I read all the reviews and one dealer was trying to sell me on the premier but then I realize they do not sell this model and that’s why they were pushing the Premier. I have tried other pool cleaners from local companies that let you try before you buy and this is by far the best pool cleaner I have tried yet so I bought this one. Some people say it does not climb the walls properly and some say it doesn’t climb the steps I have to tell you it does everything. I clean my pool every few days and my pool looks spotless. I absolutely recommend this unit to anybody looking for a quality pool cleaner with Wi-Fi capabilities. It took me about two minutes to figure out how to use the remote control on the phone because you have to know that no matter which way you turn it the front of the machine responds not the way you’re looking at it. You need to figure out which part is the front first and then it’s easy to use. People say it doesn’t hold enough debris but my pool was full of small leaves and it cleaned everything with room to spare in the 2 large cleaner filters. Between the two filters there is more than enough room for all the debris in my pool. I set it up to my Wi-Fi in about five minutes and it works perfectly. The only part I had trouble figuring out is how to adjust the handle which apparently is a float and decides how it will clean the scum line but once I figured that out it worked amazingly I added some pictures so you can see how well it climbs the walls. And it also cleans my stairs perfectly. I put it in my spa and it cleaned the entire spa even up the seat it went right up the side and right over the seat and right up the walls look at the pictures. After buying this I’m wondering why I used a pool service for $100 a month for the last five years I now take care of my own pool and all it cost me is a few dollars a month for chlorine tablets and chemicals that’s it. In conclusion all I have to say is I love this machine it works amazing it does everything it says it is supposed to do and more and I totally recommend it the people that put negative reviews either don’t know how to use it properly or they’re trying to sell somebody else’s machine or they are pushing different products, in my opinion only. I’ll add one more thing. The suction power is fantastic and it is very easy to clean.

Leave it in the pool all year round and schedule a daily cleaning in the am and then manually start it in the evening with a press of a button or from the app. Ultra fine filters only! Cleans up in 5 minutes. Black plastic can mark up the base of walls is only complaint.

First things first: get the caddy! I’m not that old or out of shape, but this is quite heavy to move around by its own. It was very hard for me to select this model because of the variety of models this company produces for online sells and also different models for physical stores. Each model is slightly different too, making it harder to compare the minor details about them. This Supreme model had everything I wanted to have on my first pool cleaner including manual steering. The manual steering is not impressive though. It has a delay, and it’s hard to control the unit. The app is also a bit unintuitive, so hopefully they work on it. I tried a PentAir pool vacuum before ordering this one, and it was a lot of hassle to setting it up, attaching the hose, and running it over night while the pump was on high speed. It wasn’t silent, and it didn’t even do a good job at cleaning, so finally I bit the bullet and ordered this. My first run with the Nautilus with the bigger fall/spring screen mesh filters that were already inside the machine was very smooth and silent. The WiFi took a few minutes to setup, and it kept failing until it suddenly started working! After that, it was as simple as dropping the machine inside the pool and hitting the clean button. It took 2-3 hours and did a wonderful job. You can see the clean lines among the otherwise greenish pool on the second picture. I have an irregular infinity pool, so after the first run, I dropped it into the other side which is like a narrow rectangular spillover 3x30 ft., and it worked there too. One nice thing about this machine is that it is bidirectional! It works and scrubs both going forward and also while going backwards without the need to turn. That’s why even in a narrow space, it could easy go back and forth between the two walls. Second day I tried the ultra fine filters. They even picked up more dirt from my pool. I’m very satisfied with the cleaning power of this unit over the PentAir vacuum I tried before. Downsides I’ve seen so far: 1- cord is hard to manage. It has a tendency to jump off the holder by its own. A latch or something would’ve made it perfect. 2- brushes are not as fast as I thought they would be, but they clean well enough. 3- app can be better. 4- heavy. 5- doesn’t do steps. 6- price!!! It should be at least 30-40% less for what it is. I will update this review in coming weeks when I’ve used it more. Good thing is that it has 3 years of warranty. Update 2022: After 10 months of ownership, I’ve saved almost the full cost of the unit and caddy by firing my regular pool service company. However, I should disclose that measuring chlorine levels and balancing the pool costs about $15-$30 per month, but I measure the levels extensively like every other day. In addition, I have to brush the pool myself every other week which is not a fun thing to do. Other than these hassles, I’m happy that I don’t pay any maintenance pool fees, and strangers don’t come into my backyard every other week. In a 3 year time, I will be saving at least a net of $3000 when deducting the cost of the unit and water balancing, so I would say it’s a good deal. Thanks for reading, and YMMV.

Warranty requires you to ship the whole unit back at your expense. So even though I did some troubleshooting and identified that the blue cable is damaged, support issued me an RMA but they still require the whole unit, including the unit itself, the blue cable and power supply to be sent back to the service center. Considering that the unit is bulky and heavy, the shipping will cost about $100 from my place to the service center.

After putting up with the awful Polaris 360 for way to long I finally replaced it with the Dolphin. I just wanted something that wouldn’t spend it’s entire life in the corner. I got that and an absolutely amazing pool cleaner. The difference is night and day. You unpack it, plug it in and put it in the. Pool and the cleaning starts effortlessly. The machine climbs and cleans 8 foot walls including the waterline. This is a truly amazing machine. I give it my highest recommendation

I purchased the product last summer and has been awesome. I’ve had a pool for 9 years and this cleaned the best drop it the water and turn it on. It does the rest. It picks up the smallest of dirt and debris and stores it away. The filters are easy to clean and last. Well worth the money.

Stay away if you want reliable remote connectivity. System requires rebooting all the time (on nearly every use). Must restart app or power cycle device to reset to good state. As this is what the app recommends it must be the case that this is by design. WiFi signal is strong at unit location. Save 700 dollars and get the non WiFi version.

Today is my first day using this and so far i've noticed it learns as it cleans! When it first started cleaning the waterline, the front roller would grab onto the protruded & rounded brick above it causing it to loose contact with the wall. This went on for the first 30 - 45 mins of the cleaning cycle before it made adjustments and suprisingly corrected! The more you use it, the better it gets! I'm happy so far, no red light of death yet. I'll update if needed. Btw, you can get this on poolsupplyunlimited's web site for the same price and it comes with the caddy. EDIT: A few months in and I can say it still works well but isn't as smart as I expected. It has no idea when you pull it out of water and will continue to operate as if its still in the pool. Also I don't get messages when the bins are full. The software is also weird about setting it to 3.5 hours from the normal 2.5 but that's a nit pick.

The Dolphin is a good pool robot. A caddy is very handy addition, but if like me, dropping another $180 seems too spendy, here is a budget alternative (see photo). Its not pretty, but it works. Hand truck: $40 Tool box: $18 Spring clamps: $6 Pool noodle: $1 TOTAL: $65

Cleans the pool great. Glad I bought it.

New robot failed after owning for 2 months have already sent in for warranty repair and received it back more damaged and still not fixed. It used to clean great but now just limps around in circles for a few minutes and then gets an error light. Also the wifi connectivity is garbage and the unit refuses to pair to wifi after working for several weeks. Very dissapointed.

The media could not be loaded. Don’t buy if you have any feature in your pool. This will probably work in a basic pool with no stairs, steps or benches but in my case, it get stuck all the time on the stairs or bench and spend most of it’s time in place.

We have a 40' salt water lap pool and live in a very windy place. So, debris and leaves etc have to be removed daily. this Robot is so much better than any other method we have used. Although it is pricy, compared to an outside pool service, this robot will pay for itself in about 5-6 months. It runs circles around our old Polaris and is actually cheaper to run........uses less electricity than the pumps that break down. We love the Dolphin and the folks at Maytronics are wonderful to work with. We'll never use anything else.

Eureka! Given these times, I’ve been taking care of my pool myself. These robots are not cheap and I had tried another model before that got stuck on the drains and the steps and almost meant that I had to sit and monitor it all the time. This guy… I put him out there, I checked on my phone a few times, and when I came back he was right where he started and had ended the great job. This may not be the cheapest model… But it does a stupendous job!

I loved the little robot vs my current one that works off a separate pressure pump but this unit sometimes would stop mid clean and need to be power cycled by disconnecting the power line. Returned it and debating, do I buy the same unit and hope for better luck or just stick with the power hungry pressure side pump robot I use.

My granddaughters are the best judge. They see a speck and won’t go near it. They said the pool was perfect after i ran this cleaner. I love the handle for lifting out and the filters come out the top.

I cannot believe the poor customer service and quality we got from this product! It stopped working after only ~6 weeks' use. We emailed the company and, without finding out what the problem was (other than it just stopped working), they sent us a new power supply. This did not fix the problem so we let them know. They made us ship it back to them, AT OUR EXPENSE (+$65)!!! What we received was an obviously used replacement and a power supply that DIDNT WORK!!! For as much as we paid for this thing (well over $2000!), I would've expected better service. I just hope it'll now continue to work for several summers (although I highly doubt it since it's been such a problem so far)

I'm pretty impressed with the job this does cleaning, unfortunately it wont go all the way up my stairs but that is do be expected with my stairs design.

DON'T BUY DOLPHIN PRODUCTS. had a problem within a year and their 'customer service' will see to it you don't get your product fixed for the entire summer. They don't even have the part. how can you sell a product and not have the parts to honor the warranty? Customer service, instead of addressing this issue, just hangs up on you. I spent 1500 on this junk I can't even use for a full season. You know how much a new power supply is for this unit? $500... if you can even find it.

Over the last 30+ years of owning and maintaining a in ground pool...... this is indeed the very best pool cleaning device I have ever owned. Certainly cost the most.... but, certainly, thus far, has given me the best results and personal pleasure having. This is a Adult Big-Boy Toy for sure.... costing aprox. $1500!! But, I am worth it...... and so are many of you! Once your sold on the idea of a automatic debris collection device.... working independently of your Main Filtration Filer..... The Dolphin Supreme WiFi Robotic is ...... Superbly the best! -Superior Filter Trap and easy clean up. Can do in a 5 gallon Bucket with a hose! Will brush up the finest debris such as sand and algi scum and of course leaves and such. -Cycles are 2.5 hours and their are many to choose from! Works from you phone. -Actually scrubs the water line and walls! I now do very little brushing! So far..... very happy!

I am blown away by this sweeper!! It is a wonderful tool to keeping your pool clean. It is a little heavy but worth a little strain to get a job well done. The program was very easy to set up in my phone and Roboclean was off doing his job!!! Highly recommend this pool sweep!!

The filters are easy to remove and clean.

You get what you pay for. This is my third try at a pool cleaner. We have a lot of residual plaster, from new pool install, plaster dust, and a lot of sand from surrounding landscaping or lack of . This cleaner gets it all, an dI mean all. leaves, super find dust, fine sand. programmable. two large collection bags/compartments. we use the fine screen filters and man alive do they work. Could not be more pleased. Im a tough critic. so I assure you... the is worth the money.

We have had our pool for over 10 years and this is the best pool sweep ever. My pool has never been so clear. It is worth every penny

Was able to get it working in the pool within minutes after opening the box. Very easy to link to my internet and phone. Does a great job at cleaning and the remote control option is excellent although I rarely have to use it as the Dolphin cleans the entire pool on its own. Cleaning the filters is very easy. Only downside is that it is a bit heavy so I am ordering the cart holder.

It even cleans the edges and removes fine sand that goes through our big filters.

My house backs to the woods before this purchase I would spend hours cleaning the pool each week. This pool cleaner is so effortless…I haven’t gotten the app to download on my phone yet but from what I see I don’t know how anyone could have a pool without one. I do have a kayak above ground pool with a vinyl liner, so far no issues or concerns. I am keeping the pool open a bit longer this year as I’m getting some back yard renovations done, this thing has even picked up a few small stones that found it’s way inside the pool. I can’t wait until we reopen the pool next season. I’ll actually get to spend more time relaxing in it versus the hours I wasted cleaning it!!! If I can get the app to download that will be my bonus. I’ll be able to program it from anywhere. This is the best gift a pool owner can have. I didn’t order the caddy but as soon as I find the one for this I will purchase as it is a bit heavy to carry back and forth. I have even used it in 50 degree weather and it worked fine without any issues.

Easy to use and my pool was clean in one hour. WOW!

Amazing clean my pool great

GET THIS VACUUM

Works great. Even goes up the steps. Powerful suction. Prompt delivery

Awesome vacuum but I wish it did stairs

I tried it today, easy to use and i connected it to my phone ....the app i easy to install I have to contact them because when i changed the mode for cleaning only the floor the robot continue to go on the wall........it is my first use so, hope they will give me a good explanation because the price was high so i expect a high quality

My weeks are so busy, and I just do not have the luxury of time to do proper pool cleaning. I thought of paying for a weekly pool guy to come and clean the pool, but that was very expensive. Really expensive. So I was stuck with the “robotic” pool cleaner I had. You know, the one that gets attached directly to the skimmer. But it often got stuck in the corner or didn't clean all the areas. In other words, it needed a "babysitter." I knew I had to buy a real pool cleaning robot. I made a list of what I wanted the robot to do, and the CC Supreme made the shortlist. I have done a lot of research about robotic cleaners, and this is the one I decided to purchase. It is expensive, to be sure, but it is worth it. I have had it for about two weeks, and it does what it is supposed to. I am very impressed. I highly recommend it.
