Dolphin Cayman

Dolphin Cayman Robotic Pool Cleaner Review

Best Price
The Dolphin Cayman Robotic Pool Cleaner has the following:
  • Scrubbing HyperBrush removes the toughest ontaiminants stuck to the pool wall + HyperGrip Rubber Tracks for superior wall climbing
  • For stubborn, stuck-on contaminants, traditional vacuum pool cleaners just don’t cut it. That’s why the engineers at Dolphin added the HyperBrush to the Cayman. Spinning twice as fast as standard pool brushes, the HyperBrush dislodges stubborn contaminants for a deep clean of your pool’s surfaces. Cleaning struggles like cloudy water, algae bloom, and build-up may be due to the fact that your cleaning regimen only treats the symptoms, rather than attacking the source of the problem.
  • With its top-access filter compartment, simply lift the Cayman’s top hatch and grab the cartridge handle for easy and mess-free removal. No more fiddling with cumbersome debris bags.
  • Traditional wheeled robotic pool cleaners struggle with slipping as they clean. A layer of water can get in between the wheels and the pool surface, causing the robot to lose traction. This lost traction is a big blow to efficiency, and adds up in the long run for the pool owner. Dolphin’s engineers hold themselves to the highest standards of efficiency, and this slipping problem just wouldn’t do for the all-new Cayman.

No frills just a great working pool vac

Steve - Reviewed in the United States on August 28, 2022

Love the Cayman. After owning several other pool robots we settled on this. Large basket for collecting big debris, powerful enough vac to sick up everything in the pool and exposed tracks do it NEVER gets stuck on anything.

Pretty Decent Robot (this is after the initial cleaning)

Thomas B. Mccaffety - Reviewed in the United States on May 28, 2021

I bought this robot as a "spare" since a motor burned out on my Polaris 965iQ and I am awaiting the parts. It cleaned very well. I'm a little underwhelmed by the lack of options such as the ability to control it in the app and select the floor only or wall/floor clean option for what it costs. (it was really only a few hundred less than the Polaris which does everything).... Overall, I liked how it cleaned on its initial, and its a really nice looking, easy to use machine. I would recommend.

Effective Pool Cleaning Robot

Kris - Reviewed in the United States on June 12, 2020

This is a great in ground pool cleaning robot. Easy to clean. Much easier than the Tiger Shark. It comes up out of water to clean side walls. This version can’t be controlled with cell phone but can be scheduled to turn on daily/weekly. The only negative is it has a bright blue cord which stands out on our neutral colored pool deck. Very pleased with this purchase.

Spend the money and get the better unit.

John Milan - Reviewed in the United States 🇺🇸 on May 29, 2020

I liked this unit because it is easy to clean. I used to after I opened the pool. The unit only runs for three hours a day unless you cycle the power. It would only go up one wall and not always pick up leaves when it ran them over. Only goes up walls in one direction. Sent pack and ordered the premier.

Operation of Robot is Slow

Theresa DeShields - Reviewed in the United States 🇺🇸 on July 23, 2021

Machine randomly goes around the pool and skips most areas. It takes almost two hours for the unit to clean a small, inground pool.

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.

Need the basket filter where can i get them?

Filters and basket are both available on

can this be plugged into an extension cord?

Yes it can.

will it work on above ground pool? especially will it clean walls?

My pool is an inground. The unit did not seem to work very random and only went up 1 of the 4 walls. The Caymen has small wheels on the front with no brush so it only cleans one way. It will not go up the wall going forward. I sent mine back and ordered the Dolphine Premier. I ordered the remanufactured unit. Wont arrive for another 2 days.

Will this work on an above ground pool?

i saw much less expensive options for above ground, so wouldn't recommend this one.

Do you make dolphin t15?

No, that unit is outdated. The Dolphin Cayman is the newer unit.

Description used two motors 24 volts but didn’t say use battery or not

It works on 110 volt

Will this work for a 16x32 pool?

Yes! It should work great for your pool!

the description claims "no" for water line that because this unit does not climb walls effectively?

It does climb walls. It comes partly out of the water.

works for 220Volt ??

No, 110v plug.

Does it have a 3 yr. warranty?

It has a 2 year manufacturer warranty! If you’re looking for a 3 year warranty, take a look at the Dolphin Premier and Dolphin Sigma!

I want to purchase the product, does the price include the taxation that exists in Bishkek and customs clearance? Or in Israel will they demand an add

floor to walls are not curved will dx3 go up the walls?

Yes he will crawl up walls ours are not curved He will not run on our beach deck area cause the water is too shallow

My pool has a liner and the Cayman has worked very well all season.

El voltage de energía eléctrica para Cayman. ¿Supongo que es 220 V?


How long is cord?

18 meters 59 feet

can it be used in dirty pool water with Ph levels off?

Yes it does a great job cleaning up dirt, algae, leaves, and whatever else is stuck on the sides and the bottom of the pool

Is there a t15 cleaner?

how deep will vacuum go?

It does not have a max depth and can handle any depth found in a residential pool!

Why is it the Fast mode and delayed operation button are not working

This particular model does not have those features. The control pad is a universal pad for all Dolphin models of this generation. I contacted Dolphin with the very same question when I first bought it. This model runs on only one mode. I bought it as a spare to my fancy Polaris so it works for that application.

Dolphin Cayman use batteries or re-charge batteries and it can use to vacuum ?

No batteries it just gets plugged in and you turn it on after it's inside the pool

What is Dolphin return policy for pool cleaner robots?

Contact your seller. Dolphin is a manufacturer

What is the weight of the unit itself. I see 14lbs then I see 24.8?

It is because the 24lb is the shipping weight which includes the unit, power supply, and all the filters and accessories! The unit itself is significantly lighter!

en que mvoltaje funciona, en mi pais la corriente es de 220 volt

what is the volume /dimensions of the debris container?

The Dimensions of the filter basket is 9.57in x 7.48in x 5.79in! It is huge and can collect almost anything in your pool!

Is this the replacement for the dolphin active 20?

Yes, this is the replacement for the Dolphin Active series!

Which micro filter box fits this model?

Funciona con 220 volt

If it breaks. Where do you take it to get fixed under the warranty?

Contact your seller and Maytronixs.
