Aaron - Reviewed in the United States 🇺🇸 on July 9, 2021

This thing is absolutely awesome. This is my first robot vac, so I can’t compare it to the many other units available, but for us it’s been a game-changer. It seems as though (after about a month of use) it’s learned our pool, and cleans better than ever now. It was great out of the box, but now it even gets the steps and ledges. Great at climbing the sides and getting above the water line as well. Put it in the pool, press one button, and walk away. When you come back, you’re pool is clean. I obviously can’t speak to the durability/longevity yet, but I will definitely update if there’s an issue. I take it out of the pool when it’s done cleaning because I don’t like the idea of it sitting in chlorinated water all season. It may be fine that way, but I’m erring on the side of caution and babying it due to the price! I’m a healthy, strong adult, so pulling it out of the water is not an issue for me whatsoever. It feels like about 30-40 lbs when you first pull it up, but the water drains out quickly and it lightens up in no time. If you are elderly or weak, that may be an issue for you, but most adults shouldn’t have much trouble. I did a lot of research before buying this model and I’m not disappointed, but I’ll just say that if you’ve never tried a robot vac, get one! This one, or any one is better than vacuuming manually into your skimmer/filter system all the time! I may get through the entire year without having to backwash…

Works as described

Amazon Customer - Reviewed in the United States 🇺🇸 on May 26, 2022

I've only been using it for a couple of weeks and so far so good. If I had any complaints I wish it had included the ultra fine filters as they are nearly a $100 extra

Plug and play (or drink)

Stancoman - Reviewed in the United States 🇺🇸 on June 4, 2021

If anybody is wondering, it's perfect for a 20 x 40 pool. The cord is long enough keeping the modulator10' from the pool edge as they recommend. No need to ever have to power vac which costs an upwards of $150 each time. Some people make comments that it doesn't climb the walls but if your walls have an incredible amount of algae, even Spider-Man can't climb the walls. I'm using the fine filter for now but am investing the $50 for the ultra fine filter to get the "crystal clear" look to the pool. I highly recommend this and would give it 6 stars if I can. There's no need to pay the extra $300 to control it on your own with Wi-Fi or Bluetooth because it does it on its own. It's easy to use. "Plug and play" (or drink) I say.

It arrived not working, but once we rebuilt it, it works fine

Lorraine Sheehan - Reviewed in the United States 🇺🇸 on June 21, 2021

When the product arrived it worked for 20 minutes and then stopped. I spent an hour with customer service, who then sent a youtube video for me to watch to fix the machine. It involved unscrewing the housing, taking out the motor and resetting it back into the machine. It did work after that. I got the impression that this happens all the time because the customer service person just started with those instructions about having to take out the motor.

works way better that hayward shark

Ryan M. - Reviewed in the United States 🇺🇸 on June 28, 2021

delivered next day! that was unexpected. arrived as described - dropped it in the pool and it went to work. I had a hayward shark xl for years but had to replace the pump when the cable connection rusted and shorted. worked for 2 more years and then the motorized gears went. when i dropped the dolphin in the pool the next day, i was amazed at how much sand and fine dirt it picked up a day after the working shark cleaned the whole pool. The dolphin is way more efficient and the cleaning of the basket filters is so much easier. highly recommend this pool cleaner - expensive, but worth the price in my opinion.

Get yourself one!

Dana & Kevin - Reviewed in the United States 🇺🇸 on July 12, 2021

This is my first robotic pool cleaner, so I don't really have much to compare it against. I will say that it works just as advertised and has helped me greatly in getting my pool back into great shape after a lot of maintenance was done to my pool (new lines, new filter, new pipe). I love using my Dolphin ( nicknamed 'Dwight') and cleaning is easy as well. I did buy the ultra fine filters just recently and they are worth the extra money. This thing climbs the walls often and seems to cover my whole 16x32 rectangular pool with ease. I will never be without Dwight again.

After purchasing 2 Polaris pool cleaners the last 10 years, I discovered this robot cleaner to be extremely efficent. The pool is truly sparkling and I only use it 2x a week. It climbs the walls as advertised and cleans the tile line. When compared to any pressure run cleaner, this is hands down superior. Do yourself a favor and try this model. You'll be surprised

Dolphin Advantage Ultra! Name says it all!! Thank you!! No time wasted here. Three hour cycle provides ultimate cleaning when needed. Plug it in, submerge it, pull it. Pop the roof, pull the basket, swing the basket bottom down and rinse the micro mesh. Sit back, relax and enjoy the show 👍😎

Motor broken after one season

nothinghead - Reviewed in the United States 🇺🇸 on May 22, 2022

Bought this unit in May 2021, it worked great for the first season, which is approximately 3 months in my area. Just opened the pool and the unit has problems with starting up. It will roll forward about 3 feet and then stop. Unfortunately, I am just a week past my 1 year "limited" warranty so I'm kinda screwed. These devices should be more robust for the price.

read the reviews before buying....I didn't

jeff NJ - Reviewed in the United States on June 10, 2021

Mine is doing more time thinking than doing ! It moves 3' then twitches left or right and reverses 3' , repeat, repeat. It has made it to the waterline a few times, and shuffles 6". Doing the waterline like this will never do the whole waterline in a year. I chose this one because it did not require a smartphone app. Not sure what to do as I have the Universal caddy and cover on order elsewhere. Not happy is an understatement. With regard to its cleaning ability, I guess it's probably OK, my pool is already clean so difficult to tell

DO NOT BUY!! Does not filter out fine dirt.

Barbara - Reviewed in the United States on May 29, 2021

Purchased the product from Doheny pool supply. Purchased it to replace my old Kreepy Krauley that operated on the pools filtration system. The main reason I purchased the product was to reduce the burden on the main DE filtration system I was very disappointed to find out that the robotic cleaner does not really clean your pool. It picks up larger debris like leaves, worms, bugs, etc. but does not remove fine dirt. The fine dirt is blown through the fine screen back into the pool where the pool's main filtration system catches and removes the dirt. The water would become cloudy when I operated the Dolphin Advantage Ultra and is further evidence that the unit was merely re-suspending the fine dirt. It should referred to as a scrubber not a cleaner. That said, I still had to scrub the pools water line even after running the robot for 3-3hour cycles. I contacted product support at Doheny and their response was "I needed to run it longer". DUH!! Running it longer keeps the dirt suspended so that my main DE filter removes the dirt. They also want a 20% re-stocking fee to return the item. VERY DISAPPOINTED!!!!

great waterline cleaning robot

Corry - Reviewed in the United States on June 16, 2021

It is very light robot to carry in and out of the pool. I wanted a robot that clean the waterline around my pool. Anyway this robot climb up to the waterline and front brush is rubbing against slightly above the waterline. I am quite happy with it.

Question & Answers

Why won't this cleaner climb the walls?

The above ground robotic pool cleaners are designed specifically for cleaning the FLOORS ONLY.

What is the typical life span of a Dolphin robot?

The Dolphin is designed to last many seasons. However, the lifespan differs from Dolphin to Dolphin. Many different factors play a role, such as amount of use, pool chemistry, and pool surface.

What DIY repairs can I complete on my Dolphin?

DIY repairs should be completed by an authorized technician. Please contact your local retailer for service, Maytronics directly at 1-888-365-7446 or the support page of our website.

What are the voltage requirements for the Dolphin power supply?

The Dolphin requires a standard 120v outlet for power.

Does it map the pool?

No but I've had no complaints with how mine has cleared my 32' x 16' pool. Hasn't missed any spots regularly and doesn't get hung up. Owned it for more than one season.

it shows mobile icon on robot next to schedule. Is it controlled and scheduled by mobile over wifi and bluetooth?

I believe you can but I don’t use it that way.

is it safe for vinyl liner pool ??

Where do you buy the ultra fine filters?

Will this cleaner work in a salt water pool?

It would but I don't recommend this item because the app is gets disconnected from the cleaner every 10 seconds and tge customer service never call you back with the problem

What is the difference between the nautilus cc, advantage and the ultra advantage?

Which fine filter basket works with this specific model? It came with a medium filter but it does not get smaller particles.

I ordered the cartridge filter kit S300, (part number 9991467-R4) the same time i purchased the pool cleaner. I only use these filters when using the pool cleaner as they do pick up smaller particles.

What is the warranty for this model?

One year

What kind of warranty does this product have from manufacturer

One year
