I’ve wasted a LOT more $$ on much more expensive cleaners (Polaris & others) and there is no better bang for the buck than this DX3. However, after 6 months the blue power cord is showing severe signs of deterioration and I don’t expect it to last. I ALWAYS purchase an Amazon 2-year warranty on these as they ALWAYS die right around that time. Don’t waste your money on machines that are 2-3x the price of this one - they are all pretty much built the same and last only about 20-23 months. This machine’s Achilles heel is the blue power cord not being made durable enough (deteriorating), and the cord also not including a self-spinning 360° attachment that prevents it from binding up

The robot does a pretty good job, but to be honest I'm a little let down in the overall performance given the price I paid. Before I purchased this robot, I was manually cleaning my pool just about every other day. I did it frequently just to stay ahead of it. I have some overhanging trees that tend to drop little leaves and pods regularly so every morning there is just a little dirt that needed to be sucked up. I bought this vacuum to save me some time during swim season. Before I first used the robot, I let the dirt in the pool accumulate for about a week or two. I really wanted to test the robot's capabilities right out of the box as I was anxious to see if it lived up to the hype. After the first cycle (it runs for 2 hours then shuts off, not 3 like the manual says) there was still more dirt on the bottom than what I would have liked to have seen. I ran it 2 more time (total of 6 hours) and the bottom was pretty clean, but not spotless. Over the next week, I put it on a daily run schedule and was pretty pleased with the result. The pool wasn't spotless, but it was 95% there, and given the time I saved not doing it manually, I'm happy with the purchase. One thing I should note (as stated in the manual): The robot doesn't have any sort of memory that helps in cleaning your unique pool. I assumed it would "map" my pool each time it was turned on so that it would be more efficient each time I used it. IT DOES NOT DO THIS. Every time it turns on, it starts with a clean slate as if it was cleaning my pool for the first time.

We have had the Dolphin for about a week now. The water in our pool was literally green since we weren't able to maintain it without the cleaner. We have run it several hours a day and to our surprise it has cleared the water up. It picked the dead algae and well as chlorine residue of the bottom of the pool. We were concerned it wouldn't be able to do this but in about 4 days it was back to blue! We live in Texas with very hot humid weather. Shocking the pool is a regular required maintenance and when the algae falls to the bottom it needs to be vacuumed out or it just builds up. We had a Polaris for many years and it along with the pump was pooped out. It also just stirred the algae up and made the pool cloudy so it was good to see we could clean the pool without going through the pump. The only reason I gave it 4 stars because it does not clean steps well so we still have to sweep those but everything else has been working very well. We are very satisfied. Also the filters that came with it are small enough to catch small particles so no other ultra fine filters were needed.

This was one of my better purchases, much less hassle than the supply side type. But at almost 11 months the power supply kept on tripping a gfci. Called and they did not bat an eye, had all my info , and will be sending a replacement power supply. will keep you informed.9/1 replacement power supply $499 glad its still under warranty 9/15 still have not received replacement, called company, on backorder. 9/25 e-mailed company still on back order , available on amazon for $415 3 weeks and counting

Let me tell you, we got the DX4 on a Saturday. It had trouble cleaning at first for more than an hour, then it was a half hour then only lasted 10/15 minutes - this was through that one day Saturday, just wouldn't stay cleaning the 2 hrs it was supposed to. Emailed the Amazon seller, emailed the manufacturer. First thing Sunday morning had an email from the Manufacturer. Odd answer, said motor may need to be 're-seated' due to shipping, sent me an instructional video, seemed a bit intimidating and weird, but tried it. Low and behold! It actually worked and was a simple fix. Yeah yeah, you spend all this money on it and shouldn't have to disassemble the thing but hey, it worked, better than sending the thing back - it's a cool robot! Anyway, has been working since and its been a month. Ok, so the Amazon seller contacted me after the whole ordeal - said I could send it back - well what the heck! I already fixed it! Nix that. Ok, on to the next issue. The power pack seemed to 'bubble' up over the push controls. Not good. Can still put the robot into action, but cannot choose any other option. Well emailed manufacturer again. They will be sending a new power pack out - once it is in stock - we'll see how long, it's been a week now, but hey, the thing is still working for what I need it for right now. I'll update on the shipping situation once it does come in. They did tell me it could take a while, so whatever. They are awesome to deal with - manufacturer I mean :) - be sure to register your robot as soon as you get it. We love it so far even with the bumps involved~ *update 6/13/22 - received the replacement power pack. Looks good, hoping it stays that way! DX4 still working amazing!

Excellent purchase! Love our Dolphin! Only issue is the rubber feet fall off, often. They do get picked up by the Dolphin, so we can pick them out of the debris when cleaning the trap. I’d purchase again.

Works great, easy to grab in and out of the pool, easy to clean. You can't ask for much more other than to wish the price were lower. Don't leave it in the pool, but take it out after every use and it will last a lot longer.

I've had it one day and it has worked well, in general. I posted a question here about whether the DX3 is supposed to have the "foam climbing rings" the instructions said were important but which were not installed. I went to Dolphin customer service and learned a day later by email that the DX3 does not come with foam climbing rings and that they'll notify their own marketing department not to put that page of instructions in the box. Well, yeah. One point off for having erroneous instructions in the box and delaying my start. Later I'll either raise or lower the score. The first cleaning cycle took under three hours - small pool - and got most of the bottom; I can see a few spots that it didn't cover. It did a good job on the curve where the pool bottom and sides join. It got a small portion of the sides and waterline, but not nearly a third. I t did get up on the swim-up seat and did a little there. It tried to do stairs but gave up the second time it almost tipped over; I wasn't expecting it to do stairs or swim-up seat. I think it's necessary not to judge its coverage on any one pool cleaning, but rather wait until five or six cycles and then judge what it has covered. So far - pretty good. Still works well after a couple of months. It deserves five stars so I've added one. It seems to climb well without the foam climbing rings.

Overall, does a very good job. It seems that where my pool has curves, it does not clean up as well and leaves a little debris. I had a CC Plus with dual rollers that did a better job. But overall, the pool is really clean and I just brush the remaining items. No regrets and a solid unit. Super easy to clean. Do have to be careful when retrieving from the pool as I have accidently opened the filter door a few times which spills into the pool. Once you learn how to grab it, not so bad.

I've used this pool vac 3 times so far. Our pool is 16 x 32 inground liner pool. We also have a "walking" ledge around the deep end. I thought the ledge would cause the pool vac trouble, but it really didn't. The vac catches all the yuk from the bottom of the pool in the filter basket (one that came with the vac, not the micro filter). I LOVE that the handle pops up when you open the vac. Not kidding-who wants to stick their hand in to find a handle? My vac filter basket didn't close properly (the bottom wouldn't 'snap' closed. I called Dolphin and they are sending out a new filter basket. Great customer service. I registered my vac the first day I received it. When I called cs about the filter basket, she answered the phone and addressed me by name. (Love that!) We have a collapsing skimmer line so needed to find a way to vacuum our pool that didn't need our skimmer/pool filter, so this was a perfect solution. I purchased the universal caddy too, although I wish my vac fit better on it. (See separate caddy review.)

I was cleaning my pool daily in the hot weather. I got tired and said what am I doing Went on Amazon and purchased the dolphin. Life saver. Does a fantastic job even picked up a dead mouse. Should have purchased years ago

I bought this 2 years ago. I love it it’s a wonderful item. The warranty is two years and unfortunately two years and two months is when it stopped working for me

This machine does a great job but I have to do 2 cycles to get pool totally cleaned. It also has a major problem climbing my stadium steps. More often than not the cycle ends in the deep end and I have to pull it to where I can raise it from the pool. These issues are not key because other than that the machine does a great job.

I was little hesitant to spend $650.00 for a pool vacuum, but I was very pleasantly surprised how good of a vacuum DX3 model was. I read couple of negative review about not working or it does a wheelie on the pool floor and does not vacuum the debris from the pool floor. That was not the case with the one I got. I didn't close our pool all winter and kept the pump on when temp got near or below freezing temp (I had the heat tapes around the pipes) just to keep the water movement. So naturally, my skimmer collected some blown leaves, small tree limbs and debris, so I had to keep my skimmer clean all winter. I tried to keep the pool free from debris as much as I could using the net, but by the time March, April came along, I had some algea looking thing visible on the bottom of the pool. First few times of the vacuum use (in mid May), I would empty the vacuum filter maybe every 30 min, just to keep the filter clean. But after the initial "Spring clean" phase, I would let it do it's thing just one cycle a day. I really don't even need to vacuum everyday, but I just like the way the pool looks after the vacuum does one cleaning cycle. It picks up sands, little rocks, bugs, and pretty much anything that can fit thru the vacuum opening on the bottom of the machine. I'm very pleased with it. We have 33 X 16 inground pool. Not huge, but big enough for us. :)

work great and save my time. It did clean up including dirt. Even though it climbs up the wall and cleans it, it does not climb all wall areas. I still need to use the brush for some areas.

I’ve never left a product review, but I’m 2 margaritas into a slow weekend and ready share my one year relationship with this little guy… Does he take 4 hours to do what you could do with a net in 30 minutes? yes. Does he pass over leaves, missing them by millimeters and moving them 1 foot out of the way? yes. Does he do wheelies in the middles of your pool floor for no reason? Guilty as charged. But somehow, after 2-4 hours he has our pool floor spotless, including sand and small particles we’d never grab with the pole and net. I did a time study (minus the margaritas) and determined that over the course of a week, between manual pole and net vs. this guy, this guy saves about 30 minutes after set up, (2) 2-hour cycles and cleaning the basket twice a week. But the value of “set it and forget it” and getting on with your life while he does his thing far outweighs the hour of “reaching scooping” leaves and debris each week. I will caveat this by admitting our pool is practically a commercial property with the number of visitors we host each month in Florida, so your cleaning needs may not be as strenuous as ours. For the price and value this guy is a strong “buy!”

Good suction, wall cleaning and easy to clean. Have in-ground pool, does great job.

I'm tempted to give the Dolphin a 5 star rating, but I have see how durable it is over the long term. It's very easy to use. The instructions say to no use an extension cord, but I connect it to a GFI and it works just fine.

We should have done this years ago. No more standing in the sun for an hour sweeping the pool. Just set it in, plug it in, and come back later to unplug it, lift it out, and hose it off (the filter). It seems to go around the pool with no rhyme or reason, but it cleans the whole thing. Our pool is vinyl, in ground, 3 to 6 feet deep and the deep end is hopper shaped. "Rosie" has no trouble going up and down the slopes of the hopper. We've had no trouble with the cord tangling. Let's just hope it lasts. The DX3 is one of the cheaper ones, but still an investment.

The control panel is water resistant not water proof so it has to be be taken down after each cleaning as I have to stretch it out into the elements to have enough line to reach our small pool. So using the settings to set up automatic cleanings is not an option. The other issue is the cord is light and twists/tangles up with every cleaning. It does have good suction power and is easy to clean. The latch on the basket seems to be getting worn. Will have to see if it holds up.

The only thing I didn't like was the control panel is so light that when the cleaner moves along the pool as it pulls on the power cord it pulls the control panel off the table. I had to tie the cord to a chair to stop it from moving. I thought the docking station came with the pool cleaner...It didn't. Kina miss leading when I ordered it. I thought it said it came with the unit.

I am having trouble with the filter basket. It won't stay closed so when I try to remove it to empty and clean it I have to reach in and manually hold it closed in order to remove it. I am afraid of breaking it if I try more forcefully to close it. Any suggestions?

The unit functions pretty much as promised. I have some concerns for the filter basket as it feel a little fragile. Time will tell. I like the basket over the previous double blade type collection design where you remove the entire bottom of the unit to clean it out. The unit climbs the walls well. No real complaints just fingers crossed it is rugged enough to last a good long time.

Ordered two robots from different companies. Both units were defective. Had the hassle factor of returning. The dolphin worked right out of the box. Would recommend it.

I bought this robot vacuum simply because I needed it. My unground pool just switched from an D.E filter to a sand one. However the sand filter that was installed the first time was damaged. So for a week straight the filter was pumping all the sand into my pool. Every last piece. 6lbs of Sand in my pool later and after three days of constantly vacuuming and filling my pool back up with water I decided to buy this vacuum. In just a week twice a day this vacuum cleaned my pool spotless! It was soo cloudy and this little robot gave us our pool back. He would run for 2 hours and be so easy to clean when he got full. 10/10 approve of this product. We now put him in once a week and he climbs the walls and everything still. Now apart of the family, we named him Gary.

This is a no frills robot vacuum cleaner. It does not talk to your phone, it does not connect to blue-tooth, it does not make you coffee, but what it does do, clean the bottom and sides of your pool, it does fantastically well. And that is why I bought it. It is not clear in the description that it actually comes with the fine mesh basket, but it does, which was important to me because of the fine sand that gets into my pool living in the desert. It is built very well and the plastic and all components feel very high end quality. I drop my submersible in my pool, plug it in, press the power button and two hours later the pool bottom is immaculate. Why in the world did I struggle for nine years with a manual vac set up? This was money well spent!

Well engineered, easy maintenance, basket removes and cleans easily and my pools never looked better. I unboxed and dropped it in the pool, it ran about 20 minutes and stopped. I pulled it out and pine needles were visible in the discharge, I didn’t have one of the filters locked into place and it dislodged enough to cause junk to get where it shouldn’t. The impeller can get jammed with debris and sand grit can get into the drive where the motor assembly meets the drive system this is both normal and although infrequent planned for the robot disassembles with a Phillips screw driver and 6 screws in a few minutes for easy cleaning. The power transformer and cord are also easy to test with a volt meter. After cleaning mine it’s run half a dozen two hour cycles without a hitch and done a good job of coverage on my pool even with the irregular sides, seats and steps. So, I give this 5 stars because there’s not much to go wrong the mechanics aren't complicated, I think it the easiest appliance I’ve ever worked on and it cleans my pool like I would expect. Additionally the local pool supply recommended this model to me as the easiest to repair with the fewest problems.

We have had the Dolphin DX3 for our 18 x 36 Horizontal Pool. From the very first time of use, the wife and I frankly in awe. Up the walls, cleaned whole pool in less than two hours. Very simple to put into pool, remove from pool. NO tangling of hose. Please purchase the dolly and cover....which makes it so easy to protect and move the unit. The control panel is one button push and it takes off, then shuts itself down at end of cycle. You can program the control to do daily, weekly, odd days. NO, we have no connection to Maytronics, we are just very happy users...............See below why we are so happy. NOTE: WE LEARNED TO TURN OFF YOUR POOL PUMP, JETS ETC. - when there was no ports blowing out pool water and to stir up the pool floor, the unit then picked up even more. After 9 years of fighting a Polaris, it was trashbin time. The Polaris, midline unit, came with as part of the pool purchase. For the first 3 months, worked pretty, except tangling of hose. I don't want to berate Polaris, but all the time, it was parts, wheels, etc. plus it constantly hung up in the hose and only cleaning maybe 50 sq ft.

This cleaner was ready to go when I received it. It does a great job of getting small particles of dirt and scum from the pool. Easy to remove after cleaning and the basket is fairly easy to clean with a garden hose. I purchased a set of finer filters and it was awkward to revamp the filter box. I wish that I had two filter boxes so that I could choose the appropriate one to use. Also would like the model with gps. The model I have cleans randomly. The bottom of my pool has wrinkles and bumps which cause the cleaner to change direction. Bottom line: If you can afford the cleaner with GPS, get it. If not this model does a good job!

Very happy with this purchase . Cheaper and better than shark vac.

The pool cleaner does not preform to my expectations. I have been using the Proteus DX4 for 2 weeks now. My pool is a 16x30 plaster pool. 10 feet of it is a 16” deep sun ledge. The pool cleaner will not clean this area. It will climb up on the ledge and then back off of it into the deeper part of the pool. With this in mind, it’s only attempting to clean a 16’x20’ pool. The proteus will randomly run around the pool area with no particular pattern climbing the wall occasionally and often in the same area that it has already been. Never has it even climbed many parts of my walls and water level areas. There are parts of the pool floor that it never goes and many areas that it goes over numerous times in a 2 hour cycle. It does a lot of wheelies and blows debris around on the floor of the pool. Today the vacuum got stuck 5 times on the drain. Speaking of the drain, Your drains need to be cut off or your drain will suck all of the debris that the vacuum has picked up out of your Proteus basket. Today the drain was cut off but still got stuck 5 times. I called customer service and the lady was no help. I ask if she has a better model that she could recommend and she said that the Proteus was one of the best that they have and only offered for a technician to take a look at it if I wanted to send it back, but sounds like it’s doing all it was designed to do. 🙈. I must admit that I am pretty OCD and retired out of the medical field where I was used to high quality and expected products to preform superior. It’s time Dolphin gets up to date with pool ledges and modern day pool designs. Would I buy again. No

What can I say? I'm beyond impressed with this robot. I have been in the "pool world" for decades. My family had a pool, my wife and I worked in the pool business for a while and we have a lovely 8 year old Doughboy pool ... but never in all those years did we ever use a "robot", I didn't know what I was missing! PROS: * The Price. I have been shopping for various units and the prices for "larger pool" robots were over $1,000, and at the price we paid ($849 - 5% Amazon Store Card Credit), it is a STEAL. * It Freekin' Works. Look, I love my pool, and don't really mind vacuuming it, but as the season progresses and more leaves and dirt get in the pool, it really became a drag to do it. I can say without hesitation, that I will probably never have to vac the pool again! When we opened the pool, the water was clear but there was some "gunk" and algae on the bottom. We put this in (Using the pleated filters) and within no time it was CLEAN * It Cleans The Walls, Water Line and "Corners". The one job I truly hate in the heat of the summer, is catching / scrubbing those pesky occasional "algae spots" that sneak up on the walls. This unit cleans the floor, the coping, the edges and climbs the walls to clean all the way up to the water line. SO far, no algae spots are in the pool. * EASY To Clean and Maintain. Just pull out the unit, open it up, empty the "basket" and wash off the filter panels with a hose. Takes a few minutes! * The Dog Loves It. Our Dachshund loves to sit by the pool and watch it work ... and so do I :-) CONS: * Wish There Was More Run Time Options. I knew going in that this unit does not have the bluetooth features the higher models have, but I would like the ability to run the unit more than once a day OR run a little longer. This is the only "con" I have so far! * Manual Was a Bit "Lacking". There were some questions I had about the product that were not answered in the manual since parts of it were "universal" to all of their units (including do not remove the foam circles on the cleaning roller ... this unit didn't have those ... and it took me 5 minutes to have realized there was an asterisk in the manual saying "not all units have these". Minor thing. Bottom line? If you are looking for a robot cleaner, do yourself a favor and snag this DX4 (or any in this line) and I guarantee that you will LOVE not sweeping your pool during the season!

The good: *Large collection basket that’s much easier to clean than previous years models. *Thinner anti-swivel cord helps prevent tangling. *Unit will purge air on its own, so you can just drop in pool. *Water line cleaning is excellent. The Bad: *Controller/PSU is not water proof. Maytronics support says it should be kept out of rain, their suggestion was keep it off the ground and cover with plastic. *Controller/PSU has a short cord and the manual says not to use an extension cord. Support says you can use up to a 10’ heavy duty extension cord. *My pool (18’x36’) is standard distance from house and power outlet. Even hanging the controller/PSU on a deck that is fairly close to pool with a 10’ extension, the cleaner cord barely has enough to reach entire pool. *it avoids cleaning one corner of the pool for some reason. *Cleaner gets hung up on low profile floor drain, if the basket is carrying a certain weight it won’t break free. *Has trouble picking up sand caught in liner creases. Not sure what they were thinking with the Controller/PSU design. How do you make one for an outdoor pool cleaner that is not waterproof, especially when it provides a function to schedule cleanings? And they should provide a much longer cord or design for use with longer extension cord or bump up the cleaner cord from 60’ to 80’.

I did not realize how dirty my pool was until I ran the DX3. So happy so far. Will have to see how it holds up over time. Right now I am very happy with my vacuum!

This works great and cleans walls and floor. Great buy

Everything works great, one problem, door on basket broke the second time we cleaned it.

Easy to set up and use.

So far this is a great robotic pool vacuum for my inground salt water pool. Works great picks up sand particles and everything in its path.

The item arrived ahead of schedule an was very easy to set up. i have used it once in a 15 x 40 pool. it did not get everything in a 3 hour cycle but left a small amount of debris on the bottom. as far as i am concerned, it is quite acceptable. my old Tiger Shark lasted 17 years before it quit. If the Dolphin lasts that long, i would give it 5 stars.

Plug and play. You will need a nearby electrical outlet Very reliable and the tracks allow it to scale pool wall and steps. Plug it in and forget about it. I will say that it is not good for small pools because it displaces a lot of water so it will stir up dirt in a small pool.

drop it in turn it on and let it go it does its thing no issues

Great

Product works well. Does struggle a bit getting up steeper side walls. But does a great job cleaning pool. Do wish the cord was a bit longer but still works well for us. Seller sent this extremely fast!!

I have bought three different pool sweeps before testing this one and by far its the best one. It climes the walls and also gets ever section of my small pool. It does have a hard time doing steps but over all i'm super satisfied in my purchase.

What I disliked about it was it was not new in the box. It did not have the plastic rap that was supposed to be on the wheels that the instructions said to remove and it was dirty. Also not packed very well.

I don’t usually write a review, but I must comment on this. I purchased this at the end of March, it landed June 1st great delivery time. I used it for about 3weeks, went on vacation, came home on July 1st dropped it in the pool and turned it on. It ran one cycle, when I went to run it for a second cycle the brain was dead. I checked the GFIC receptacle it was good and on, I plugged a fan in the same receptacle so power coming in was Not a problem. So, freaking out I came in and checked Amazon …. This was the last day for a return. I sent a return request in and Amazon approved the return. So, first thing July 5th I dropped it off at UPS. As of this date I have not heard from the manufacture. So, I will give it a little longer before I freak out, I don’t know about you, but $700 bucks is a lot of money. Now for the machine itself. If you have had an old AquaBot this is not as powerful, but it did the job but again if you are looking for something that will break the water line and scrub your tiles this is not for you, if you can live without that this should work for you. Now have own two AquaBots the controller on them were massive medal boxes compared to this controller, but they all seem to be going that way. My hope is, since I am this invested, the ship the machine back with a new controller as there didn’t seem to be anything with the machine itself. I have. heard that they will deduct a restocking fee if you want a flat out return Or they may deny the return itself. If that is the case I will have to bring it up to Amazon as this is advertised as Amazon pick or choice or whatever they say. My Amazon page was flooded with this machine popping up, now if I didn’t make the purchase I could excuse this. All I know is my pool is going to hell and I have no idea where I stand as of this date. 7-8-2022

Works very well, climbs the walls, super easy to clean.

Does a great job, awesome product

Works as advertised and super easy to use

After years of having my Polaris spray my windows, patio furniture and anybody that happened to walk around the pool I decided to make the switch to a robotic cleaner. I was tired of buying the Tail Sweep Pro and the ridiculous foam brushes over and over again. Did I mention my wife constantly complaining about the dirty windows and patio door? Anyway - chose to go with the Dolphin Proteus DX4 after a lot of research and talking to my pool maintenance company. What an amazing transformation! First off, no spraying outside of the pool. Secondly, the DX4 scrubs the whole pool bottom, sides, and even comes up and cleans the tile at the water line!! Super clean pool now compared to the job my Polaris did. Of course, it's not perfect but I think the trade off is worth it. It has a hard time picking up small branches that sometimes end up in the pool, but it sucks up everything else like a champ. As a point of reference, we have tons of crepe myrtles around the pool so we have more leaves than normal - zero problems with them. The only recommendation I have is to buy the caddy for it. Since you have to manually drop it in the pool and take it out when it is finished - the caddy makes it very convenient. One added note - my wife loves me again - no more window cleaning!! Now if they could only invent a little mini one of these to run around in my hot tub.....

I’ve been using the product about 2 weeks now and while the robot cleans my entire small pool, it takes at least two cycles to be thoroughly clean. The Proteus on runs for two hours per cycle with no way to change cycle duration. While I only need to push the button again, if I’m not home it could interfere with plans upon returning. My pool is only 12,000 gallons and roughly 25x14 feet. I believe the issue with not getting all the fine debris is the power of the Proteus displaces the debris near its path which then resettles in a previous cleaned area. Overall, I’m pleased with the purchase but I wish I could adjust the length of a cycle.

Does a good job!

This unit was purchased to replace an 8 season and still running aqua bot Classic. The differences between the two units are obvious immediately . While both cleaners vacuum the pool and clean the waterline, the DX4 is superior in it's navigational pattern. The older model that I had would get itself hung up in the frame of the ladder and stay stuck for 10 minutes The swivel feature is a plus as it allows the cord to follow the cleaner without getting kinked up. Last, but not least is the filter basket as opposed to the cloth bags of yesterday. The basket is a huge improvement and is easy to clean. Pool cleaners require a certain amount of effort however the DX4 requires much less time fighting the cloth filter. I expect that this will give me good service.

I have tried many tools to clean my pool.But by far this one is the best.To hire someone to clean and brush down the pool evey day,would be not be affordable for most of us.But the Robot will do it for you and won't complain 😀 My pool has never been so clean .!!!! I would Highly recommend this product. PS:The wife is so happy.!!!!!!!

We have an expensive cleaner that quit on us and while it was being repaired, we decided to order a cheaper one to use whenever the other was out. It works great!!

I like this DX3 a lot. I've used it twice a week for a year now and it does what it's supposed to quite well. I purchased a basket with a fine filter since living in a desert a lot of sand/dust and tiny mesquite tree leaves/buds gets in my pool. In case the manufactuer reads this: there is room for improvement. 1) It is unnecessarily hard to remove the lid when it needs to be removed in case debris gets stuck in the outlet tunnel. 2) There are two small covers on the bottom that fill up with mesquite tree bud spikes. In theory they could be removed using a fingernail, realistically you need a screwdriver to pry them out. 3) The spring that lifts the basket handle is an unnecessary gimmick. Waste of manufacturing and labour cost. 4) the plastic that covers the control buttons started bulging up only after a week of owning this. Probably not enough glue used. No big deal but it takes away from perceived value. These things I noticed makes me wonder if designers actually own and use the things they design.

I've owned Dolphin products for years and they have been great. After several years from my current model, it was time to replace. Unfortunately, this is the second unit in two weeks that I received and on this specific order, the Wifi cannot find the robot. I spent over an hour on the phone with Maytronics (vs. just returning to Amazon), and still no luck. Maytronics support is really good, and they agreed to replace the entire unit, but we landed on just the controller, as the actual robot works just fine in manual mode. Disappointing that two successive orders had problems, but hopefully the replacement controller will solve this. I'm still a fan, but feeling a bit more suspect now.

It blows everything out from underneath it before it sucked it up, so the small particles that create what I call plankton doesn’t get sucked up so your pool continues to look murky. It also doesn’t follow a distinct pattern, since it doesn’t have that ability. Spend another $500 and you can get it much higher costing item, but will that pick up the plankton on the bottom with a blown it everywhere? I don’t know.

does clean good ... just wish it can memorize the pool map

We have a serious sand problem in our yard so vacuuming was always a task but this little guy makes things a breeze. It’s so easy to use and clean and really does a great job. Only downside is I wish it had a remote to be able to tell it where to go for the spots it sometimes misses. Otherwise it has definitely been worth the investment!

didn't expect the performance to be great, but suprisingly it is better then I expected

Nicely priced and does a great job

It does a pretty good job. If there is a drawback it is that the cleaning is totally random.

I've had the DX4 for about a month now and it works flawlessly every time I put it in the pool and turn it on. I just set it and forget it until it is done. Cleaning the filter is easy as well.

My pool is 17'w x 29'l x 5.5'h, in-ground vinyl lined pool. 20,000 gallons. The Dolphin Proteus DX3 works great. Easy setup. Cleans sides and bottom of pool. It's programmable. I really like that it's not hooked up to my pool pump/filter, dirtying that up. The basket is super easy to empty and clean. The one real downside is it's not able to clean the stairs. It tries but I don't think the stair treads are deep enough. I would definitely recommend.

Short answer, Yes. There are innumerable similar products and reviews aplenty. Deciding which will fit your needs, expectations and budget is a task to be sure. I read several and finally had to pick what I thought would fit us best. This is a quality brand with positive reviews. Ours is a medium size pool (23,000 gal) freestyle. Previous cleaner was a Polaris three driven by a booster pump. This was the setup when we first built the pool about 10 years ago. It was good and you could tell when it wasn't run. The Polaris has been rebuilt more than once and the booster pump finally gave out. This prompted the search for something new. This DOLPHIN DX3 is doing an amazing job. The floor and walls are the best they've been and the water stays clearer. It operates better than I expected and has raised the bar as far as I am concerned. Especially at this price point, I can recommend.

I have used the unit three times. It is easy to set up, cleans well on the bottom and up the sides of the pool. It climbs up the bottom step but has difficulty getting up the next step. It's cleaning pattern is random so it needs to be guided to areas that it has missed. Very easy to clean the filter basket. The unit comes up short in my opinion, because it does not have a swivel system at the point where the power cable attaches to the robot. Still, very happy with the purchase.

excellent product

I have owned a 16' x 32' inground pool for 19 years, and this is my 2nd summer using this pool cleaner. I live in western New York, so I have to deal with leaves, seeds, cotton from cottonwood trees, etc. I CANNOT BELIEVE THE DIFFERENCE THIS CLEANER MAKES!! I have not manually cleaned my pool since I bought this. It keeps my pool ridiculously clean, and the only "help" I give to pool cleaning is to brush my steps occasionally, and maintain the chlorine and pH. My pool was so clean when I closed my pool last year, my pool had NO GREEN in it when I opened it this year. That is the first time that has ever happened! I should have bought this years ago, and I STRONGLY recommend it. I do run the cleaner daily and rinse out the filter screens in it every 2 or 3 days.

Product arrived in an undamaged box. Unboxed and followed directions to put in pool. Powered it on and nothing happened. Unplugged, waited 5 minutes, then plugged everything back in still nothing happened. Called the seller and they said to submit a request through Amazon since I Purchased it through there. Submitted a request through amazon and they said to contact the manufacturer. Contacted the manufacturer and was informed that components shifted during shipping. Restrained myself from asking why they didn't put a couple of pieces of styrofoam in place or at least a sheet of paper explaining the fix. Manufacturer had me remove four screws (Two from the top, then two from the mount revealed after removing the top and the cowling under it) then "Shift around the motor" followed by re-installing the screws. This resolved the issue. Product appears to work well, though feature wise it is incredibly lacking. Lacking Features: Scheduling function is worse than rudimentary What the heck is the reasoning behind the "You have to set it up again every week?" function No real error handling Instructions are non-sensical (Can't plug it into an extension cord?) Can't stop it from wrapping the cable around pool features. ---September 28,2022 Update--- The Issue does not only occur during shipping. When you put it back into the pool, you need to ease it in, dropping it into the water from just a couple of inches up is sufficient to displace the components that shifted when mine was shipped.

Ease of use. Does a great job cleaning without much effort.

This works well but there’s no rhyme or reason to where it goes so spots do get missed. It’s powerful and will climb steps and sides but it just doesn’t cover entire area. For the money it is worth it except for the fact the cord tangles horribly. It’s not supposed to. Straightening it out does not help even with it if water. It immediately tangles again as soon as put back in pool

My previous pool vacuum died. I went with Dolphin this time and I don't regret it. Immediately opened the box, put him into my pool, and 2 hours later the cycle completed and the pool was nearly all clean. Like I said, my previous robot died, so my pool was getting pretty slimy and the floor had fine dirt on it. I ran it another 2 hour cycle, and all the fine dirt is gone. The top load basket is so much easier to clean than my previous bottom mount bag system. I just love everything about my new pool boy !!

I did not want, my wife did, I lost. It’s here and I love it! Does a great job at the coving and top of the wall I drop it in, hit the button and go mow the lawn. Easy to clean. Only draw back is no floating style handle to lift out of the pool. I solved that by fabricating my own with a pvc T, poly rope and a pool noodle.

Use to clean a 20x40 ft pool. Works very well

We bought the Dolphin Proteus DX3 when our Dolphin Sigma died for the second time, 26 months after purchase, as a backup for the Sigma, because while the Sigma is still under warranty, many parts are backordered and the warranty requires us to ship the product back to the manufacturer. Which is another issue entirely. The Proteus costs less than half of what the Sigma does (And did. It's $500 more now than when we bought it!), so we knew it would be a lesser machine, but hoped it would get us through until the Sigma (a great machine, breakdowns not withstanding) is back in functional order. I put it in the pool a couple of hours ago, and it did clean the pool, including vacuuming out accumulated leaves. But with half the scrubbers and fewer motors, it doesn't clean as well or as efficiently as the Sigma. Which was to be expected. The real problem is that when I pulled the Proteus out to clean the large debris basket, I discovered that there is NO WAY to keep the basket closed as it's pulled from the machine. It opens EVERY TIME, dumping the debris right back into the Proteus. Much of it fell back into the pool I'd just cleaned. As I carried the basket to and from the grass where I rinsed it out, it refused to stay closed. That latch is TRASH. Completely ineffective. What is the point of a debris basket that just dumps the debris out the moment it's removed from the vacuum? I had to take the entire machine across the yard and hold it upside down to rinse it out, because the design prevents you from rinsing the erroneously dumbed debris from the machine itself when it's upright, or even on its side. Yes, this machine was "only" $700. But with this design flaw, it's worth less than nothing. Don't waste your time or money. The two stars I gave it are because it does actually clean the pool. If slowly, inefficiently, and less well than the better Dolphin models. Not that that matters, if it's going to dump leaves and dirt right back into the pool.

If companies really wanted to know how their products are performing they’d wait a few weeks before sending out surveys. Having said that, the Proteus seems perfect for my small inground pool.

I love this robot cleans excellent pool looks fantastic!!!

It's nice well made easy to clean. The power pack is ok seems easy but occasionally it glitches. It's cleaning capability is ok. I wouldn't say it's great. It seems to have a hard time getting in the corners and then will get stuck and stop running and I will have to restart it. Seems to get confused when we start in on our taming ledge. All in all it works ok but we still have to get in there and use a manual vacuum. I do wish it had The capability to memorize the pool instead of having to relearn it every single time. Perhaps those features come with a different series however this was nearly $1000 and should've had that capability.

Love this cleaner so far. Much lighter weight than my previous cleaner. Easy to clean after use.

I love this pool cleaner. I had the polaris for years and it would always get stuck somewhere in the pool spinning it's wheels and wearing down the plaster. This new one is amazing. It really does climb and scrub the walls. For a little more money it really is worth it.

unpacked it threw it in the pool and let her go, boy she sucks fairly good, tends to slide down the angles of the pool and once in awhile has a hard time getting over the bottom drains. great to see it climb the wall and scrub the top of the walls . Unfortunately it will not map out the bottom of the pool but overall not a bad product.

Return policy is worthless! Can't return if used. Can't figure out if any good unless you use it. It's just okay. It worked (after spending some time getting the bobber switch to work cause it was stuck and wouldn’t start). Now that I've used it for several weeks, I'm not impressed. It works, just not very well. Poor suction, cleans minimally . Gets stuck on bottom circulation inlet over and over. Have to grab it and pull off to go again. Running it over and over again gets good results. However, timer is only an hour or so and no readout when cycle is finished. You just need to check on it often for getting stuck or timing out and manually push the start button again. And, again. And again! My old Polaris 9450 worked much better and was easier to clean filter too. It's problem was it only lasted for 4-5 years, then died. For almost a grand, I expect better from BOTH units. Guess Im stuck with this under-performer until it puts me out of my misery and dies. Just watch, this dang thing will keep doing a crummy job forever!

Easy to use and easy to clean. I like that it works independently and not dependent on the pool pump. Great investment to keep my pool in top shape.

The product works well. I got the fine filter basket option. My version did not have the remote option. This is my only regret.

It cleans pretty good. This makes the 3rd automatic pool vac that we've had. Only improvement that I can see is the cable. I had to disassemble it down to the impeller within the first week of use because it got some debris wrapped around it. It kept shutting off. It didn't take too long to take it apart and clean it up but I hope I don't have to do it very often.

Super happy I purchased this. Works great and cleans the pool nicely. I have a rectangle 24x12 and it’ll clean it in an hour or so. Wish it wasn’t so expensive but definitely beats hand vacuuming

I had a chance to stick with an older model dolphin Nautilus CC plus (virtually the same price) or this model. While the nautilus lasted 5 years, I was sad to see it go. I decided to switch to this newer model and quickly found, it just didn’t pick up as well. With that said, it does work, just at a slower pace. The basket catch system is much easier to clean! I. also haven’t figured out how to figure the Bluetooth options, but overall, a good purchase! Pray for good years ahead!

A friend let me borrow hers for a couple of weeks until she opened her pool. It saved me soo much time and effort cleaning that I bought this one as soon as she took hers back. It is soo easy to use and cleans the bottom better than I can do in 30 minutes using a hosed vacuum.

It would be great if it had a way of easily storing the cord

I did a lot of research and glad I landed on this robot. It does a fantastic job cleaning the pool. Is well built and very easy to use…just one power button to turn on and start the cleaning cycle. Debris basket is huge and extremely easy to remove and clean…takes about 30 seconds each time. Highly recommend this robot!

Easy and effective

Love this robotic vacuum. It’s super easy to use and does a terrific job!

I bought it after years of manually cleaning my in-ground pool. This little robot has simplified my life and gets lots of stuff off the bottom of the pool that I didn't realize was there. So easy to clean it too! Wish I had bought it years earlier.

Vacuum does a great job. box arrived damaged, but robot appeared okay and tested it for a week and it is working good. Not sure who damaged and retaped the box.

This is a great pool cleaner. The big bucket makes it easy to rinse out. Love it!

We loved the Dolphin other than it would not go across our drains in the bottom of the pool, and we had to manually push the Dolphin off the drains. It did a good job of cleaning as long as it continued to move.

I have had it three weeks and the cleaning is amazing. It even cleans my stairs. So very happy with this buy....so far. Will post again in three months.

So simple to use, even I could do it. I put it in my pool, turned it on and watched it for about an hour as it went back and forth picking up leaves, and other items such as a dead cricket at the bottom of the pool. I was concerned about it running over its power line, but it did not do it my first two uses, so possibly somehow it knows how to stop when it comes up on it. Easy to clean basket even though one of my screens fell out, but I figured out quickly how to put it back in. I think they come out for easy cleaning. It climbs the walls with ease.

It make’s cleaning easy. Just sat back and let the Dolphin do the work.

It didn’t have a remote control. Is it missing?

After two uses seems to work great, easy to clean. Good entry level cleaner. Time will tell.

The cleaner does a good job cleaning the pool. It managed to get on one of the seating shelves and cleaned it too. Was not able to clean all the steps, but haven’t had a cleaner yet that could. Opening the door to remove debris basket could be a little easier. I feel like I’m going to break it every time. Over all, good product for the money.

He’s taking a while to learn the pool. Seams don’t get clean, but it’s a quick swipe with the brush and the sediment is gone. We haven’t had it that long, but are hopeful it will become more efficient.

I have a 40 x 20 ft inground pool and I use this robotic cleaner weekly. I have had it for 2 years now and it's super easy to clean with a large canister that holds alot of debris. It goes up the walls of my pool easily and makes my pool maintenance so much less work. I would definitely recommend this Dolphin pool cleaner to anyone who wants a reliable vacuum to clean their pool. It's worth every dollar and is not overly complicated (I first bought a Polaris vacuum with an app that could control the settings of the vacuum but returned it because it was just too difficult to figure out). This robot is not overly complicated...it gets the job done!

So far the Dolphin is cleaning our pool

Does a pretty good job. More of a maintenance type cleaner - not for opening duties. Scrubs waterline very good. Best to brush the corners because it doesn't get them very well. Have not seen it go on the stairs yet, so not sure if it'll get stuck on them. It does get stuck on the drains, though. At the price it should include the caddy. Control panel is sparse, but I'm not putting it on a schedule - just 3 hour cycles. Hopefully it will last for a few years.

Works great but will have to see how long it last before repair/replacement of wear parts.

I think it awsome

We love this! I just wish I had the option to not clean the sides of the pool if I did not want to. We chose this because of the large basket to get leaves up and it does great at that. But when March's winds come and all the leaves in my neighbors property blow into my pool and literally the entire bottom of my pool is covered, I want it to get the leaves not scrub the walls! Perhaps I should have gotten the wifi one.....but it was way more expensive.

The Dolphin Proteus DX4 seems to struggle being consistent at cleaning the pool walls. Overall it seems to require a minimum of 2 cycles back-to-back to get the overall pool clean. We have waited months for concrete, so our pool is littered regularly with red dirt. Maybe once there’s concrete it will stay clean and not require the extra work.

Works great! I Love mine. My pool has a steep incline and it has no issues getting anywhere.

I'll start this review with this: I am crazy about keeping my pool clean. I vacuum it every other day, sometimes daily. I can't stand it being dirty. If my water is dirty, I take action. I say this, because I feel my pool is cleaner than most. Well, I bought this because I love robots in general and I thought it would help me keep a clean pool and save some time. I opened the box, dropped her in and hit power. 3 hours later, after running a complete cycle, I was expecting to find a little debris, but I found all types of stuff, including fine sand particles. It was amazing and I was rather shocked. Also, watching it scrub the tile waterline was just plan cool. Also, I love that it is self-contained and doesn't fill up filter with sand and dead bugs. I highly recommend this cleaner for anyone looking for one. Can I give it 6 stars?

Does not climb the walls to the top and have to turn it on twice to clean the entire pool

I've been asked to rate the machine. I only used it once so far. It worked well. A higher rating will need to stand the test of time.

Easy to use right out of the box and cleans great! Goes up the walls and back down- no flips with this vacuum! Highly recommend. Only bad thing is the cord sometimes gets tangled and it’s stuck for a little bit other than that it cleans great!!

Heavy when pulling out of the pool. No weight noted full of water especially if waterline is set lower than average. Had to contact Maytronics service day two for unit not functioning as written - had to disassemble unit to disengage and then ‘reset’ motor. Now functions as desired.

This thing is wonderful. Put it in the pool in the morning. Where we live we have a lot of sand in the pool. This gets a ton out. It leaves a bit in the corners, but way better than doing it by hand!!! Love this product!

Didn’t clean all the bottom of pool

Very easy to use. Does not get hung up on stairs great for my 18 x 36 inground pool

The media could not be loaded. It really works!! I was so skeptical. As it says in directions to take out all filters and then put them back in and start it. It would go a few inches and stop ! This happened all the first day and read all reviews that said to look at motor. It was the filters were not in there good that was causing it to start and stop! Once i got those in , it did great!! It vacuumed up sand I accidentally spilt and it comes on and cleans cleans cleans!! I am super happy with my purchase!

I purchased the Proteus DX4 robotic vacuum for one week ago. I have probably ran it ten times. Today I observed the performance for the entire 2 hours. The pool is 30’ X 18’ and kidney shaped. The circumference of the pool is 85’. I ran the DX4 for the default 2 hours. The pools pump is a variable speed and was running at about 1/3 maximum speed. I started the cleaning at the remote end of the pool in the shallow area. I have started the DX4 in different areas and get similar results. The DX4 climbed the wall 15 times in 6 areas which covered 25 feet or 30% of the pool circumference for water edge scrubbing. This seems disappointing, especially only scrubbing in six areas, 30% of the pool. The DX4 spent over 1/6th of the time around the main drain cover. It would back up and continue running over the drain cover. The main drain is shut off and not used in this pool. The main drain cover meets the new standards to prevent personal injury when the suction is turned on. The DX4 seems to prefer using the center of the length of the pool and only branching right or left in the six areas identified for water edge cleaning. Numerous times while climbing from the deep end (about 6’ deep) it would seemingly stall and abort the climb to the shallow end. I also observed it frequently moving forward and backward repeatedly only covering about a foot in either direction. Attached is a picture showing the six areas where water edge scrubbing was observed. The areas where there are no black buckets indicates there were no attempts for water edge cleaning or cleaning the pool floor. From my perspective the coverage for my pool was poor. I purchased the DX4 for the Water Edge Scrubbing and the Swivel in the power cord. Neither feature met my expectations. I expected the DX4 to cover the entire pool in the 2 hour cycle. I contacted Maytronics about my concerns last week, and the rep suggested I clean the impeller. The pool is screened and was manually cleaned before using the DX4, so I was confident there were no obstructions and the DX4 was clean after disassembling and inspection. I have also completely unplugged the unit, thinking the unit might reset, but the coverage characteristics are similar on the next run. Maytronics is willing to run diagnostics since the DX4 is within warranty period, only one week old, but I have to pay for shipping which seems ridicules. I contacted Maytronics support and their recommendations were (1) turn off the pool pump during the 2 hour cleaning period (2) The also felt the issue with continuous cleaning of the main drain was also tied to the pool pump (note the drain has a plug in it) (3) Be prepared to manually clean areas of the pool (4) DX4 will not clean steps because the water is too shallow (it has cleaned this area on a subsequent test run) I also ex[plained that I also tested a Maytronics Active Solo, which did not exhibit any of these issues and that it did an excellent job of cleaning the pool. I am a retired engineer. I have no experience in robotics.

A few things to consider. We live in an area of north Texas where it rains unexpectedly a LOT, even when the forecast says 0% chance of rain. So we can not leave a $900 electrical machine controller sitting out in the open for fear it will get wet and be ruined. This machine must be plugged into an electrical power source, so if your pool is more than 3 feet away from the house, you will have to use an extension cord, which we have to unroll 40 feet and and then roll back up after each use. The vacuum itself might only weigh 14 pounds, but when you are lifting it from the water full of leaves and water, it is much, much heavier. It is more than my strong 11 year old can handle, and almost more then I can handle; I'm 67 and disabled. The power cable to the machine must be painstakingly unrolled and fed into the pool after the vac is submerged, or it will only travel as far as the tangled cord allows. We have to tie the power supply onto the fence, as the vac almost pulled the electronic controller into the pool. The basket lid sticks and won't open half the time. Our hose for cleaning the basket is clear across the yard which I then have to navigate with my walker. With the backorder unavailability of the caddy for the setup, it's quite a chore to carry the machine power supply cable and extension cord to a rain-proof area. If I leave the controller sitting in a sunny area, it overheats during a 2-hour cycle. We have a lot of trees, and fall is a challenge to keep the leaves out of the pool. I ran it for three 2-hour cycles yesterday, and although the vac picked up some, there were still lots of leaves in the pool. Now the pool is going green. I'm not too sure this was the best bet for our needs.

Easy to put in pool, cleans like a pool co. would clean, seems indistructable

This photo after three days and three separate cleaning cycles. According to the user’s guide it does not “learn” a pool but starts fresh each time. I’m guessing it’s about 80% coverage. There were several locations that it simply never visited.

I’ve owned my pool for 4 years and finally sprung for an auto vac for the pool. I’ve swept manually about once a week. I couldn’t believe the amount of grit and grime this thing picked up. I ran it 4 times right away and my floors and walls have never felt so clean. The very fine filter nets in the basket catch all of the Sandy particles that my Manuel vac would blow back in the pool. I turn it on, close my auto cover and walk away. Takes about 2 hours to clean my 20x40 pool. Happy so far!

I’ve only had it for a month so far so good. It cleans up to the water line and stays up sliding across the water line

It is worth it. Easy to use and does a good job.

I’m very please with my Dolphin. I used it the same day that I received it. I was astonished at how well it mapped my pool and cleaned it. It climbed the walls and sucked up all the small debris that was present. This robot has made my life so much easier. The clean up is so easy. The basket pops in and out.

Ive only had for a week.. The first run stirred up a lot of the dirt/sand and made the pool a cloudy mess. I ran it two more times after the dirt settled and cleaned it up pretty well. We will see how it holds up.

Works great!

I had an older product of the same company. But, this model has improved greatly, especially the easiness of cleaning the collected dirt.

My old dolphin lasted 12 summers. This one is much lighter weight and easier to lift out of the pool and the debris basket vs the bag is gold star worthy. So much easier to clean. Literally takes seconds to rinse and return to the vacuum. Time will tell if the power source and vacuum last like the last one did!

We have a 18k gallon pool with a baja shelf and a spa. I worried that this model would not do all that the $2k+ models would do, but after having it for 5 weeks, I am very happy with it. Our pool sits under a very large gumbo limbo tree that sheds its entire canopy twice a year. This was causing me to vacuum the pool 2 or 3 times a week, which was extremely time consuming. That prompted me to look into an automated robot. If I could do anything differently, it would be to order the higher model with the app-based remote control, but in all honesty, this one works just fine. The capacity is more than we need, and cleaning particulate is a little bit of a chore, but I am just whining. I recommend this product wholeheartedly.

clean the pool floor

Hats off to In The Swim and to this vac. but careful, the basket handle will break. It did on us.

i would like to let people know it is much cheaper than buying at the pool store it climbs the walls and leaves more time to enjoy the pool than spending time always cleaning it you just put it in, and press start it's as easy as that then you can enjoy the results i use it every other day

Not sure why but the cell phone remote control does not work.

This pool sweep is so much better than the old style that sucked all the debris into the filter. Cleans all areas, sides, stairs, floor. Easy to clean out.

This is a replacement for a Dolphin Deluxe 4. The two biggest differences between this model and our previous model is the debris basket and the brushes. Our previous model had a bag. What a pain to clean. It’s like night and day difference. You could. Punt on 15 minutes with a hose on the previous model in addition to turning the unit over, messing with clips, stretching the bag to fit on the frame, etc. it was a pain. With this one you open the top, grab the handle, pull out the basket, open the bottom and spray it out. It seems a little flimsy, but it is super easy and takes maybe 5 minutes tops. Now, the ok’d bag caught all the fine dirt. This model catches none of it. So, it will stay in the poll or go into the filters. That’s a downside of having it “easy”. The other difference is that both roller/brushes on the old unit turned at the same rate at the track. On this unit, one of the brushes rotates faster, which gives it a bit of “scrubbing” capability. While the old unit would move forward and backward to change direction slightly, this unit uses side jets of water to make 90° turns. It pretty impressive to watch. I read some previous comments about this unit not climbing walls... So for it has no shortcomings in climbing the 9 ft walls of our pool and does a better job of scrubbing the waterline as the old unit.

Just like I needed although I cut off the climber rings not realizing they were not packing! 😭🥴ordering new ones hopefully it’s not too difficult to install! Works great though!

The media could not be loaded. So I'm in florida and my pool is 15x24 ft and about 9.5 ft to 3.5 deep. I did not clean my pool for about 6months. Local pool cleaners charge me 200 dollars for chlorine and weekly cleaning per month. My pool was extremely dirty with leaves at the bottom. Water was clear cause I added chlorine as per schedule. This robot handle I would say maybe 5 to 7 good shovel scoops of leaves out of my pool. I received it today and ran it immediately. 8 hours later and stopping it to clean the filter 5 times I will honestly say it's clean. I bout the dx3 model. It was stuck once at the end of the nite mind you is 1223 am but I released the filter and sent it back out there. I bout the 3 year protection plan and cost me 700 total. If it last 4 months I feel I got my money worth. Everyone is complaining it gets stuck sometimes but in reality it's saving me money and I have company over and BBQ and prefer a pool leaf and debris free. It's a good deal glad I crossed over from the pool guy. With the protection plan if it has issues I will update on that process but so far so good and I encourage other pool owners to try to manage it as well. Pro tip: if your pool as algae at the bottom this robot will try its best but I had over 5 months of growth. It tried but left streaks. I scrubbed it myself and when it settled it did pick up all the residuals. I will update if anything changes.

I bought this Dolphin Proteus DX3 Pool Robot so that I could more easily keep my inground fiberglass pool clean. I unpacked the robot and followed the instructions. It was only 2 hours after receiving it that I dropped it in the pool and hit the start button as advised and the robot went to work cleaning the bottom and sidewalls as advertised. It doesn't have the side jets that the more expensive models do but still does a really good job at getting debris and windblown trash out of the pool. Only had it for a couple of weeks now but am very satisfied so far. My wife used to spend a couple of hours cleaning the pool with the pool vac setup with my help. Now "Bullseye" takes care of it in the same amount of time with very little input from us. Would definitely buy again.

Love how easy it is to operate, and what a good job it does cleaning the pool.

I read a lot of the reviews prior to purchasing. The good and the bad. I almost didn't purchase based upon the bad reviews. I decided to borrow a friends dolphin, different version, and it worked great. So I took the plunge and purchased this one. It has been great. The pool has never looked so clean after it completes it's cycle. During the first run, it got stuck on one of the drains, but after I assisted it, it was fine. It has not gotten stuck again since that day. The customer service has been great too. The unit was shipped without the 2nd set of filters. I reached out and let them know. 5 days later, I had the filters. I'll update if anything changes.

Any time I spend over $500 for something, it better have a good warranty. The Dolphin is 2 years .But only 1year for all parts (Gears, motors, controls ,etc.) All plastic parts is 2 years, Come - On, what goes wrong with plastic- UGH! What I don't like, it should have come with a Anti-tangle cord - the higher priced ones do. I'm almost afraid to use it (Reading all the 1and 2 star) It does miss spots. What you have to do ,if you own one, is clean the Impeller often, It will get plugged -up and burn the motor up -(Go to You-Tube) they will show you how.

I had a Blue Diamond bot cleaner which is now 14 years old. It finally bit the dust this year in 2022. They don't make them anymore and the repair parts I needed were 5/7 the price of a new cleaner. So, after looking at many different models which had at least a 55' power cord, we settled on this one. I will add my 5☆ review to the many which are already out there. It works as expected. Easy to clean (MUCH easier to clean out than the BD. Easily reaches the end of the pool from the power supply with about 2 ft to spare.

Simple to use. Plug it in put it in the pool an$ go play golf. Cleans the pool better than me. Climbs the walls, great machine.

I am impressed with this ,very simple to use ,quick cleaning and great when it cleans the tiles around pool. But not impressed with the cheap made holder for the cleaner.

I think ultra fine filters should have been included for this price

It’s not a bad unit over all. Cleans the pool super good! Just wish the lines wouldn’t tangle up.

Super easy to use and setup. Bonus it works amazing.

this is the second Dolphin i have had and i know the product is good but this one did not work from day 1. i called the manufacturer and there is a problem theydetected about placement of the fan. I am sending to the manufacturer for repair

Better than expected, for the price it is great. No more vac every week

Super Easy to use and clean Just drop it in the pool plu it in and presss the button

ran for less time than advertised.2hrs versus 3hrs. not good on corners.

That I can put it in the water andforget about it. Can clean with the solor and winter covers on.

This is a great pool cleaner. It’s fast & easy to clean the basket. I wish it had a lift button on the control but I still love it. It’s not as big & bulky as ones we’ve had in the past which were a different brand. I would highly recommend. At first sight I was thinking it was too small & would take hours to clean but it really zips around & gets the job done in a couple hours.

This is a great product. For mid grade it does a great job. I have a 21,000 gal pool and it goes from deep end to shallow end, climbs walls and does a great job. You look back in your pool and he has cleaned it out! Quiet also. It cld be better at remembering a route of you pool. Mine has yet to do that.

Work great

Purchased this when my Tiger Shark finally gave out. The Dolphin does not do near the cleaning that my Tiger Shark did. Cool that it climbs and cleans the sides of the pool, but even if I run it the full amount of time, there’s still stuff in the bottom, especially around the edges. We went back and forth on sticking with what we had or trying this in hopes it would be as good as or better than the Shark. Seriously regret our decision.

Does a good job cleaning the entire pool floor. My pool is an odd-shaped 12'x24' design. Cleaner manages to to navigate all the cut-ins, stairs and rounded corners. No frills cleaner, just on-off and 3 fixed timer settings. Happy with the purchase.

Works great, leave it in water and it does its own thing and you just need to take it out of water after a bit of time. See the difference before and after use, works great!

I love the fact that this does NOT use the pool pump for suction and motion. It's all electric, and it traps all the floor debris in a very effective basket filter. I have it for about 3 weeks, very very very happy.

We had a cleaner that used the pool pump on the skimmer for many years. Took two people to get it set up. Now I can do this by myself whenever I want. Yay!

For the price we paid for this it is not executing what was described in the text. It does not go to the deep end does not climb walls or stairs. Not happy at all especially for the price we paid for it.

this is a great product it climbs they showed where it turns over not i my pool they showed where it can't clean a dug in place where you set it does in my pool this is a life saver for sure cleaned up grime very well and picked up winter sludge easily

i purchased my first dolphin over 12 years ago and it is still operational. I saw the need to either get a new product or give the old one a tune up with some new tracks and bearings. i can say with all honesty, it was the sale price and my lack of interest in the tune up. the only issues, if you can even call them that, was it would high center on one of the two main drains in the bottom of the pool. if you did not see it to remove it, the cycle would not complete. If I can do it, you can do it. so do it.

I’m happy with it. It has lessened the evil of having to scrub the side walls after vacuuming and very quiet. I put it in the water and push the button, then I’m able to do other things while it’s working to get the pool clean. In my opinion, it was a good investment!

It cleans really well and simple to use . Happy with the purchase right now .

I was looking at the DX-3 as an alternate, but my pool is 36ft long, so I wasn't sure the DX-3 cord would be long enough. The DX-3 also has 2 filters to clean and very little capacity in each for junk. The DX-4, though larger, has a single, easy to clean filter box with a large capacity. I think I could run it in my pool for a week and not dump the basket. I have used it 3 days in a row and it worked fine - though, arguably, there was less to pick up on the second 2 days.

Seems to clean very well. Easy to clean. Will validate reliability as the summer moves along. Like how it does not draw any suction from the VS pump.

the product stopped working after first time use; i.e. second day it would run for 10 minutes and stop. Customer support was very attentive and help me resolve the problem. The unit has not failed since...so at this moment I am very pleased with the product. My fiber glass pool has never been cleaner. it's not perfect on steps but good enough.

I have only used it twice since I received it but I have to say it does an excellent job. Very easy to operate and clean. We used to have a creepy crawly that had the tubing running throughout the pool and kept getting stuck in the corners. So this is a great improvement. I am very happy at this point that we bought it.

Very easy to use. Just set it in the water, turn on the timer and you are free to do other things! Great suction and ease of cleaning out the unit. We were worried it wouldn't work as well as our prior cleaner with this one costing so much less - boy were we ever happy to be wrong!

Was disappointed in the cleaning results. Easy to use but it expected more for the price.

Exceptionally pleased. Everything operates as advertised and delivery was quick. It seems to be priced pretty steep, then again this is the first time I have bought one. Also, the instructions discourage using the power cable to lift the DX4 from the pool… my pool is 9’ deep at one end; either create an instruction to return to the shallow end or provide a simple cable to attach to pole or provide a hook device. I haven’t tried the remote control features, yet.

We had debated getting one of these for a long time and finally went for it. It was worth every penny. We have used it for one full pool season and it has made a huge difference. We just drop it in once per day and it vacuums the whole pool, climbs the walls and scrubs the water line. We have had to put a fraction of the shock we normally do in because the pool is so free of debris that little algae grows. We can actually see the bottom of the pool all the time now. It is so nice not to haul out the hose and vacuum and mess with backwashing. The basket on this model is quite large so we just quick hose it out every other time we run the robot. The only two things are that it does get caught on the steps sometimes and we have to move it and start the program over. The other thing is that the first time we used it when we opened the pool it could not keep up with the amount of dirt in the pool. We had to manually vacuum it upon opening and then switch to the robot after that. Perfect for keeping up with every day maintenance. Can’t say enough good things about this model. I hope it lasts quite a few years. We have a 40x60 in-ground concrete pool.

So far so good with all !!!

This robotic cleaner is so easy to clean. Open lid and handle pops up then take out the basket and clean with water hose. So much less work than my old cleaner. Does a good job cleaning. I would recommend this product!

Does no clean well

This pool cleaner is awesome. Does a great job. The filter comes out easy and is easy to clean! Love it!

Cleaned mostly one area, would sometimes venture out beyond the deep end, but mostly not, cleaned back and forth over the same lines, not through enough. Also, the trash basket seemed to get stuck, had to force it out. If I ran it 2 or more times back to back, it cleaned the bottom ok, generally, and by then most areas were at least better. Now, returning this and for another $250, going to the Dolphin CC Plus model… hopefully it works better. This is not a reflection of the seller, only the product.

Instructions make you believe you can control with an app, but this model that functions is not available, actual control devices has a lot of option but you can’t use. I thought this unit u can set a timer but I was wrong again. My opinion this isn’t worth the price I paid.

Very easy to use and clean and works very well

The media could not be loaded. The Proteus DX4 is the first robotic pool cleaner I have purchased, and - generally speaking - I am satisfied with the job it does of vacuuming my pool. I cannot speak yet for how much this bot will save me from cleaning the big pool filter, but it does save time on scrubbing. I’ve had the DX4 for almost four months now and there is one particular issue that makes me rate this robot a 3, and not a 4 or 5. The one issue is that the cleaner often gets stuck. My pool does not have a complicated shape at all, but it has one ledge that’s about 2 feet from the surface where the robot would climb up, would then try to clean the surrounding walls, and then is unable to back up. It tries to free itself, going back and forth, struggles, and then it turns off. I then have to manually move it and restart the cleaner. I’ve attached a video with this review to illustrate the issue. To me it seems like the software should have been able to handle this sort of situation. This could happen to the top step of stairs for example, so I'd think it's a common situation. I'd be interested to see if there is a firmware update of sorts I could apply to the unit to get rid of this issue. It is quite annoying, especially because the unit just turns off. If it tried to free itself a bit longer, it could do it.

Wonderful product. So simple to use

Clean by inground swimming pool very well

AMAZING !!!!! So easy to use and works GREAT. Our pool was clean in less than an hour. It cleans very well. Scrubs the walls too.

Absolutely amazing piece of equipment. Cleans the pool better than the pool cleaner I was paying. Very happy with my purchase.

This replaced M400 Dolphin. It has been suction, much easier cleaner basket. Struggles with steps and has trouble at times with the walls. - Same as M400 Excellent on bottom of pool This model DX3 does not have the Bluetooth capability nor can u control it. Overall - good purchase

After considerable research, I selected this pool cleaner. On the surface it seems like a great labor saving appliance. The Pros: It's small, lightweight and easy to clean. The Cons: It's not very efficient, It regularly misses about 10 - 15 percent of the debris. I found myself running it twice in succession to clean my pool. I have a battery operated Pool Blaster ($139 on Ebay) and I can do in 10 minutes what the Dolphin does in two hours! For the price, I'm really disappointed.

I have an irregularly shaped pool about 30 feet long. Pop this little guy in and then collect in less than 3 hours and retrieve the basket, as shown, and low, it collects everything, even, as in this case, a basket full of acorns!! This thing has some great suction. It climbs up the walls, scubbing as it goes. Pretty clever. What i like best? Not having to manually fill the hose and plugging it into the side of the pool to vacuum the old way - I hated that! This DX does all of that without the hassles. Now it won't clean the spa...it's too big for that. It also won't climb up the wall of the spa where it is too curved, it isn't designed for that either. However, it does eall else, and I'm thrilled with it. I heartily recommend. PS - I thought about getting the more expensive Dolphin and wondered if I made the right choice....I did, no need to pay the extra money unless your pool is larger, then you might need the more expensive model.

Excellent pool cleaner on lagoon shaped fiberglass inground pool. It replaced an older aquabot and is so much quicker to clean and easier to empty, at half the weight.

Very easy to program and use and does a great job of cleaning the pool.

It has great suction power, and I like that it works from my phone! It is heavy, so if you are a female, you should have your husband pull it out of the pool for you.

So far so good, I had it 2 weeks and I'm impressed with the cleaning job it does.

Great product to clean in ground pools. Very quiet, very little maintenance, just make sure you have an outlet relatively close by. Great for daily maintenance to keep the pool sparkling or every couple days to make pool maintenance easy!

Easy to use and way more convenient than my old pool vac with all the tubes into the skimmer, etc… BUT this unit is not good at cleaning the bottom of my pool liner when algae starts. It’s just goes over it with no effect. Probably not as powerful suction as ones that use the power of the pool pump. I’m keeping it but I’m disappointed.

My pool is crystal clear. This cleans the bottom of my in-ground vinyl pool better than any filter I've used.

I’m kinda cheap and was hesitant on spending on a pool vacuum but this is one of the best purchases I’ve ever made! I used to spend so much time manually cleaning the pool now I set this robot up, check on it in a couple hours, clean the basket, then restart it. Good bye dirty pool!

We’re using this in a 18’ x 36’ inground pool & it does a great job. Very pleased & wondering why we waited so long to purchase. Easy to use, has good suction & cleans pretty much the entire pool in one 3 hour cycle. Highly recommend.

I like the unit very much. Overall it cleans the pool perfectly as well as the walls. My only wish is that it would have come with a tangle free cord. Otherwise it’s perfect.

Saves me so much time and works great

The DX3 is exactly what we needed for our pool. We use it weekly and it keeps the pool clean and clear.

The dolphin DX3 is a good replacement for our DX3(2010 model). It is easy to clean and it does a good job in our pool. It also does some water line cleaning which is nice. Highly recommended for your inground pool!

Easy to use and easy to clean

Product was super easy cleans so good tge price was good all around 5 stars amazing you will love it best invention yet!!!!

Only used it about 5 times so far but it’s doing a great job. Very happy so far, hope it lasts.

I have not had this cleaner but a month, come back in 8 months and I can give a better review. The cleaner works great it climbs my walls just like the advertisement says it would. I have one issue with the cleaner, getting it out of the pool. It does have a recessed area in it for picking up, but you have to reach down in the water to get it out. It would be great if there was a way for it to float to the top when cycle is complete like some others.

I should have purchased this years ago. We've been using a Polaris sweep for the past 5 years. I rebuilt it one, replaced the (I think it's called) the backflow valve on the hose and I even replaced the large and EXPENSIVE pump. These kinds of things to make the Polaris clean the pool really start to add up. With all that the little guy kept getting stuck in the corner and would creep along at a snail's pace, and the pool was never perfect. I finally shut it down two weeks ago and, after some research, decided on this unit. So, after 2 weeks our pool was full of leaves and small debris. Then this unit finally arrived, and after a short read of the instructions, I plugged it in and over the edge and into the water it went. The basket, which is super easy to clean (and large) filled in about 30 minutes. I emptied it 3 times... So much easier than the old bag to empty. This morning my pool couldn't be cleaner. It vacuums the bottom, climbs and cleans the walls and NEVER gets stuck in a corner. And I don't have to listen to the pump. When this operates, you literally can't hear anything. It's absolutely silent. So this spring we'll swim without dodging the Polaris and it's hose. Great purchase so far.

Cleaning the sides of my inground pool.

Although, I had problems with the motor with my Dolphin cleaner, the customer service department provided me with free shipping back to them. I was advised they would have it for two days and ship it back. They did and it works great. It does everything it’s advertised to go. Great product with great customer service.

It does a great job of picking up debris. Does an even better job of climbing the sides than my last one. Easy to operate and clean.

This robot came highly recommended by a friend and we see why!!! It's amazing and works harder than any pool boy, also easy on the eyes 😏😄

I had bought a different one first and it was not good and Amazon refunded my money Then I ordered this one and it’s awesome I HIGHLY RECOMMEND THIS ONE!!!!!

works better than any pool vacuum we ever had only draw back is didn’t come with a cart to store when not using

I like it because it cleans the whole floor and walls, but it doesn't clean the steps because it gets to the surface and start loosing internal water

Put in the machine and it went to work. Had heavy winds the second day for a good test of leaves. Worked great! Controlling the robot is a bit tricky but it works. Very happy so far.

This little robot has made my life so much easier! Easy to set up, operate, & clean! Love it!

Very good pool vacuuming product. Put it in tge water, turn it on and watch it clean.

Cleaning capability quite good for most of the pool. Struggles a little bit near odd-shaped areas - steps, swim out, raised drains...hence four stars - but otherwise very effective. Cycle takes about two hours, and you literally toss him in, straighten out and hook up the cable, plug in the power supply, hit the button...and walk away. There is no end of cycle indication that I've noted, but none is really necessary: after a couple of hours, you get used to looking out occasionally to see if he's stopped. Cleanup is a snap: pop the lid, pull out the filter basket and hose it out, rinsing off the unit at the same time. It's become part of the weekly pool regimen, along with cleaning the pool filter, so garden hose is already out. Let the robot dry in the sun for a couple of hours, then he's back on the shelf until the next weekend. Cleaning without a hiccup for a couple of months; let us see what a full season of use brings. So far...recommended

Clean gunite pool. Love it. So easy to clean when done vacuuming.

This is truly a superior product. The suction and basket capacity allow it to pull a ton of stuff from the bottom of the pool, even small sticks.

We lost our booster pump because of the freeze, no impeller to be found anywhere. We were tired of waiting and, our pool was suffering. We decided to buy a robotic cleaner to replace the booster pump and, the Polaris 280 cleaner. This eliminated both components, reducing cost and repairs. Now we only worry about the cleaner itself, and not a booster pump. We also are saving energy with removing the 3/4 HP booster pump that ran 2 to 3 hr. a day. We bought the DOLPHIN Proteus DX3 Automatic Robotic Pool Cleaner, bought it Sunday and it arrived Monday. It was easy to set up and run, just dropped it into the pool and withing hrs. it was clean. It could climb the walls and the steps with no problems. Once it was done, it was easy to clean and stored in our storage box. The only concern is the control box. It is water resistant but not waterproof. We store the control box in our sunroom, next to the pool, to keep it dry. I will build a watertight box for it so if it does rain while we are cleaning the pool, it will stay dry. In all, we are very happy with this product.

Simple to use. Works perfect on my above ground pool. Climbs walls and keeps it very clean. Definitely worth every penny

i like it very much but i have a question about the control panel it seems to get very hot is that ok or is it a problem ?

We have large trees around our pool. We had been unable to get our pool clear due to leaf litter and pollen After the 2nd cleaning with this cleaner, pool is sparkling clear. The fine pollen and organic debris on bottom of pool is gone. Filter easy to clean.

Simple to use and clean.

This dolphin is so easy to clean, the basket is a snap to clean and put back into the robot. No bags to mess with. The suction is great, we are very pleased with our purchase.

Set and forget. Seems to work well without supervision.

Cleans my 20 x 40 pool quickly and meticulously

This little guy is worth the money. We have a 25’x50’ community pool. Such a time saver and our pool has never looked so clean. Yeah!!

I am still in the honeymoon stage and hope this little machine keeps on keeping on. It cleans very well picking up even dirt in the pool.

So easy to put in and take out of pool. Easy access filter basket.

This pool had 4 months worth of leaves, pollen, and algae. This is what I had to clean after the 3rd pass. I had to wait for it to clean, and finish a full cycle before taking it out to rinse and repeat. This robot is well worth the monry. 25x25 ft circular in-ground vinyl pool Shallow end 3ft Deep end 6ft

I purchased my Dolphin Proteus DX4 in March. It does a great job of cleaning the pool, though the "kink-free" cable doesn't fully work as intended. It will still kink up. I was happy with it, while it lasted. By August, it had died. It would start up, then shut off almost immediately. I did research and checked the impeller. It had some hair in it, but not much. With that clean, it was still dead. I followed all of the troubleshooting tips provided by Maytronics and anything else I could find online. Nothing worked. I was outside my return window for Amazon, so contacting Maytronics was my only choice. Their customer service is nice enough, though the wait can be long. I received an RMA with a shipping label to send my robot to their service center. That was mid-late August. Now, almost a month after they received it, the only info I can get is that they're waiting for parts. I won't be able to get any other information until they ship it back. Who knows how long that will be. For the price of this unit, you would expect years of trouble-free service, not 5 months. Very disappointed after spending so much on it. I can't see myself buying another Dolphin when they're failure rate is high enough that the repair wait time is this long.

So far it does a pretty good job. Climbs the walls, does waterline & it does climb & clean the steps to a degree. Ordered the ultrafine filter assembly, as I most definitely need that. Very well satisfied.

So far have only been using it for a couple of weeks... what a life changer! We have trees near our pool that we cannot cut down... so the alternative is a cover or a robotic cleaner. This little fella has been awesome! We may still use a cover for the worst leaf fall season, but the cleaner is very effective and saves the pool filter to boot. Really easy to use, big basket, easy to clean. Love it!

I am still testing it, but so far, I am not impressed. It is missing areas in the pool.

I love this pool cleaner! I also love the customer service because there was a little problem when I got it and I called and they were there to help me and solved the issue. I’m sitting right now on my back porch reading instead of cleaning the pool while my dolphin is doing all the work! I definitely would recommend this and actually my pool company was the one that told me about this cleaner.

This is absolutely amazing. I opened up my pool after a year. Used the robotic vacuum and it did the job for me. Cleaned my entire inground pool. Don't go by any negative feedbacks. It's worth the money. Extremely recommended 😉

We ordered this for our smaller in ground pool after our experience with a larger Dolphin unit for a large pool. DX3 is lighter and easier to clean. But probably not as powerful. It does climb the walls and does the water line. Our pool is caged so it doesn’t get very dirty, just some leaves from the lanai plants. Works well.

I bought this Dolphin for our new pool. There was sand that blew in the pool from the leftover sand the builder left and several twigs and leaves. All i had to do was drop my Dolphin in the water and push one button. I watched as it went thru the cycle, turned in different directions and scaled the walls to scrub the tile. To clean just remove the filter and spray it with the hose. I enjoy waking up in the morning and dropping it in the pool while I drink my coffee before work.

Cleaning my inground pool clean well where it goes but is a little inconsistent over all areas

Dolphin is known for excellent pool cleaning robots, and this model, the Proteus DX4, is no exception. It is very simple to set up and use right out of the box. I had mine working within minutes of receiving the delivery. It's programmable for multiple cleanings a week up to one full two-hour cycle a day. The large, top-load filter basket is a breeze to empty and wash out. The DX4's one big detractor here is it does not have a full basket indicator to let you know when you should empty it. The DX4 has two scrubbing brushes and a powerful enough vacuum to get just about everything off the pool floor including dirt, twigs, and leaves. It also does a great job climbing the walls and cleaning the waterline without the expensive foam climbing rings found on some older models. The DX4 carries an $850 price tag which gets you everything except smart device connectivity and the aforementioned full filter basket indicator making it a great value if you don't want to pay extra for those features.

Just switched from my Polaris that had a booster pump. So far, this vaccuum is way better than my polaris. It’s only been a week but it’s much better at cleaning the pool from what I can see.

The product worked as posted on line. I have no regrets on the purchase.

Great buy!

Like the easy of used ,Dislikes took three sessions to totally clean pool and still left some sand on bottom of a new pool liner

The Dolphin DX4 is really easy to use, clean, and store. You have to get the caddie and the cover for a complete set. The only downfall is it won't do steps but that is a small issue.

Easy to use and clean clim the wall of the pool ease so the suction is great

Our pool guy recommended this pool vac and he knew what he was talking about. It cleans well, is easy to use and is easy to clean.

Si te tardabas 1 hora en hacerlo manualmente, con esto se baja a 1 o 2 minutos despues de que el robot lo limpiara. Cumple con su funcion. Algunas esquinas quedan mal barridas, pero el 98% restante lo hace de forma correta.

pool looks great with minimal effort.

The DX3 is great in concept but poor in execution. The suction appeared to be good and the unit was easy enough to clean. The unit was easy to use and the cord was not an issue. But that is where the good news ends. The unit would work its way around the deep end but that was it. Even though I would start the unit in the 3' shallow end it immediately would find its way to the 6' end of the pool and stay there popping wheelies and therefore not really picking up too much. I really wanted this to work cause I hate having to manually sweep the pool but it costs too much to only do a third of the pool.

The pool has never been cleaner. So easy to use.

Works great. Cuts down greatly on manual cleaning. My pool's best friend! Climbs walls well. Easy to clean, just pop out the basket and empty. Love it!

I expected this unit to help me so I wouldn't have to manually vacuum my pool as much, but to my pleasant surprise I haven't had to manually vacuum at all. This Dolphin is a great workhorse and it even comes with 2 sets of filters, fine and x-tra fine. It's not cheap by any means, but it is sooo worth it. I only wish I ordered it years ago, it would have saved me countless hours of pain. I've had multiple back surgeries and this gave me a new appreciation for my pool. Now I just drop it in, and 2 hours later its done. It only took 3-4 sessions to clean up an dark green 30,000 gallon pool to almost perfectly clear, w/o using a bunch of chlorine. Now once a week or so is all I need to keep it sparkling clear. I never was able to get it this clear, this fast using elbow grease. Now I can relax instead of stress. Does Dolphin make a remote lawnmower? Thanks DOLPHIN

Worked better than expected. Had bottom of 27' pool cleaned in about an hour. Sure beats tangled hoses with vacuum cleaner.

This pool robot was recommended to me by a professional pool tech. Needless to say I’m impressed. Plug it in and press one button and it’s off and cleaning. Filter basket is easy to clean. I like that this robot cleans above the water line also. Would buy again.

Best thing ever

Bought this cleaner several months ago and wanted to wait to give a fair representation of it. I've had a pool for more than 20 years and this is by far the best one to date. I love how it cleans all the way up to the tile. Downside - you do have to take it out of the pool to clean it. Positive - I love how it cleans all the way up to the tile. Does a great job cleaning pine needles from our three trees.

I’m very happy with my pool cleaning, it does the job and have time for work, other things.

Easy to use. Cleans well.

This pool cleaner makes cleaning a breeze

Have not owned it very long but the times I have used it it worked well. It does climb walls as claimed, the basket is easy to remove and clean and it cleaned the pool completely. Hopefully it will continue to work so well.

So far it’s great. It climbs the walls and cleans the pool in no time. I’ve only had it a little over a month so hopefully that won’t change. My only complaint is that for me it’s a bit heavy to take out of the pool. I usually have to have someone else lift it out of the water for me.

Does what it’s supposed to do. Makes cleaning your in ground pool effortless.

Very easy to use and clean.

Purchase brand new not 1 month ago (3/13/21). Finally got a chance to unbox and try it in the pool since weather is getting warm and is about time to open pool ( 4/4/21). Followed all instructions carefully, placed robot in pool, connect power and turn on power. Robot led blinks a couple of times, then starts to move. then stops, then move some more, then stops again. No lights, no movement. Power supply is still on, but robot is dead in the water. The whole process wasn't even a minute long. Turning it off and on while it's still in the water would repeat the same process. led blinks a couple of times, then starts to move, then stops, then move some more, then stops again. Search online to see if I've done anything wrong. Most comment said to check if impeller is stuck. Checked it, was totally clean, can move the impeller fan with finger. Decided to contact Seller (In the Swim Pool Supplies) on 4/5/21. Didn't get a response till 4/7/21. Their response was because I had the item for over 30 days, they ask me to contact the manufacturer directly. If the manufacturer makes a diagnosis that the item is defective, they can go ahead and assist you further with the warranty claim....WTF. It's not even 30 days. If I can select 0 stars, I would. Product deserves 0 stars for it to be defective. Seller deserves 0 stars to pass the buck. They would charge a 50% restocking fee as stated on their profile. Service deserves 0 stars for not even taking care of their customers. Should had believe all the other 1 stars review. If you want to get a pool robot, go to your local shop, and make sure they will take care of you in person. They at least would fix your robot free of charge when it's under warranty. Unlike internet order where if the manufacture would finally respond back to me (I contacted them waiting for the diagnosis) They would most likely need me to ship the unit to them (out of pocket) and wait for who knows how long before I get to see it again. I'm contacting some local shops around the area to see if anyone would willing service it under warranty, and if not, how much it would cost to fix my brand new robot. Might as well spend a little more than throw $850 out of the window.

This unit has great suction and is definately easy to clean. It took two 2-hour sessions to adeqately clean my 18x36 foot pool and it still missed a few areas. If I had it to do again I would spend the extra money for the next higher model that had remote control and could learn the pool configuration.

Very easy to operate, easy to clean and light to take out especially for a senior citizen

Robot cleaner was intermittent when put into operation. I called Maytronics Customer Service and they instructed me to perform a procedure to correct the problem. I corrected the problem and the robot cleaner works great! Great support from Maytronics.

We like that our pool gets clean on the first run! We do not have to keep on starting it to ensure the whole pool gets cleaned. It is easy to clean and light weight.

(Purchased 5/11/21, Review 10/15/21) I don't know why I put off purchasing one of these. After 18 years of owning this pool... tons of different (unreliable) pool cleaning companies, taking care of it myself (time suck), I finally discovered how great these are. I just balance the chemicals once a week and this little guy does the rest! I have to occasionally brush down a tight corner here or there, but it literally does the rest. Pro Tip... you don't have to remove it and clean the basket every time you use it if you don't normally have a ton of debris at the bottom of the pool. I will follow up if there are probs with it in the future.

Does everything I need

We have just opened our pool for the season and only have used it twice. We are still learning it's tricks but it still hasn't learned to crawl up our steps and clean. We are going to start the next time to put in onto the steps first and see what it does. Hopefully this will help.

Bought for a friend and they loveit

Really like this Dolphin! It's more powerful than the one it replaced and it cleans all the way up the sides of the pool. We got the smallest model because the price and is perfect for our needs. The only drawback is that it has a smallish leaf bin. The instructions recommend to clean everyday, which we usually do. It's a much easier process since its lighter, more streamlined and easier to take out of the pool. Doesn't leak leaf bits back into the pool as it comes out of the water. To clean just lift open the top door, grab the bin handle and lift out. What an improvement over the fabric one that was a pain to take out from the bottom. We'll probably wish we got a bigger model during the few weeks of fall, but expecting to be happy for 11 months out of the year with this one.

Great buy, makes pool cleaning easy

Super easy to clean ,quiet and efficient! So I bought one for my rental. Tennant's love it. Holds a lot of debree and seems built to last.

This is our second one and it works great!!!!

Cleans my pool really good.

Pool bot works great, and as advertised. only issue was it has trouble going up the pool stairs, however I knew it would from talking to folks before purchased. best unit for the money I could find after researching, and I was not disapointed!

Lil guy gets after it. We like him and plan on having him around for some time…

best pool cleaner that I have used yet ! I would buy it again when this one wears out !

Works great!

I wish I had purchased this sooner. I am a woman in her late 70's who grew tired of vacuuming the pool or paying someone to do it. The pool is 22 x 50. The cord is long enough to reach the entire pool. It is very easy for me to use. I have no problem placing it in or taking it out of the water. It cleans the pool beautifully. Sometimes I will run it for two cycles, if we have had a storm or heavy wind that has deposited debris in the pool. The filter is easily cleaned with a hose. I did not realize that one can purchase a caddy for it. I bought a very large bin, with wheels, and I keep it in that.. In sum, I highly recommend this product. The pool stays cleaner that it has ever been, and I have not used the pole vacuum at all this summer. I gave it 4 stars instead of 5 for "easy to clean" only because my hose is not in the pool area. It should really be 5 stars.

The media could not be loaded. I love my Dolphin! It does an awesome job and even goes up and cleans the water line and my tanning ledge. It isn’t able to do the steps because of the size but that is not a problem. The pool is spotless. It is so easy to use and you really don’t have to do anything but sit back and watch. When you take it out of the water you hose down the filter basket and you are done. Open the top, lift it out, spray it off, and put back in. Couldn’t be easier. When you lift it out of the water it floats to the top, grab the handle, let the water drain out in 30 seconds, and lift it on out. It is not heavy at at all. My pool is 11’X29’ fiberglass.

Product did not live up to description. I have a15x30 oval pool with 6 foot deep end. Vacuum would clean about 3/4 of total floor area and 1/4 of walls. Movement seemed totally random and haphazard, not mapped as described. Read reviews carefully as Amazon has lumped reviews of the dx3 and dx4 together artificially raising the star rating of the dx3. The 2 stars are for Amazon's return policy and In The Swim's full refund on product return, not the dx3 which I would give a 0.

Easy to use and what a time saver!

Delivered 3/22/21. Worked great @ 1-2 times per week in a 35k inground vinyl-lined pool until 8/17/21. Now, comes on for about 15 seconds & dies. Working with cust service. Will update review when they take care of issue. Update: Cust serv got back to me & troubleshot problem. 10 minutes later, its working great again. I had to loosen the motor (4 screws) shake it & reinstall it. Presto!

I have used this product for about 2 months. My pool was quite dirty when I first started using the Dolphin. It cleans the pool quite thoroughly, so I had to clean the unit often. It has also been very dusty and windy where I live. I run the unit every day. It runs for two hours at a time and I clean the unit about every two days now that the unit has caught up with the filth that was in my pool. It is much quicker and easier to clean than my old Tiger Shark. My pool’s capacity is 12500 gallons. Overall, I am quite satisfied. This unit does not leave any areas undone.

Product easy to use .

I thought this was a rechargeable vacuum. It is electric and cannot operate when anyone is in the pool. The cord is barely long enough to cover my 16x32 in ground pool; a longer cord is available for $275. It does pick up debris, including sand, pretty well. However, I find it cumbersome to get out of my pool after each use. Next time I’ll spend the extra and get a rechargeable model.
