Next-Gen MaxBin™

As a part of the Max-Series™, Cayman’s easy to use and highly effective MaxBin™ filtration system sets it above and beyond what you’d expect from a standard automatic pool cleaner. Its super-fine filtration allows it to clean debris of all sizes, from algae to large leaves. Its large, oversized cartridge and programmable timer means it could clean for an entire week before it needs to be emptied.

NanoFilter vs Standard Filter

Optional NanoFiltration™

Experince the NanoFilter difference. Side by side, you can see the difference between the NanoFilter™ (left) and standard filter (right).

For the first time ever, you can upgrade your Dolphin Cayman by adding its MaxBin™ with NanoFilters™. By adding this filter, it allows you to target and capture difficult debris that would otherwise be recirculated in your pool.

Dolphin Cayman Robotic Pool Cleaner

Ergonomic & Lightweight Design

A pool cleaner that’s heavy and cumbersome makes pool cleaning a chore, but the light weight and ergonomic design of the Cayman ensures the robot bares your cleaning burdens. Its frame is ergonomically designed to create the least water resistance possible so it moves efficiently around your pool. Its light weight of only 14lbs means it’s easy to transport and drop into your pool. Plus, with its fast water release program, it never feels waterlogged or heavy when you lift it from your pool by its convenient carrying handle.

Scrub 2X with HyperBrush™

A powerful brush is a must when it comes to effectively cleaning away stuck on stubborn contaminants. The all-new Cayman features a HyperBrush™ to dislodge stuck-on debris with brushes that spin two times faster than ordinary brushes. Dirt and debris don’t stand a chance against the Dolphin Cayman.

Dolphin Cayman Scrubbing Brushes
Dolphin Cayman Tracks

HyperGrip™ Rubber Tracks

The Cayman is equipped with HyperGrip TM Rubber Tracks to ensure that no surface gets left behind. The tracks grip tightly to your pool’s floor and walls to eliminate the slipping that wheeled robots experience. With the Cayman, the debris and tough contaminants in your pool have nowhere to hide.

Highly Efficient DC Motors

The Cayman’s engineers set out to build a robotic cleaner that accomplished a thorough and efficient clean while using less energy. Their success is evident in the new Dolphin Cayman. With dual 24-volt DC motors powering the Cayman around the pool, this robot uses only 180watts, or almost 90% less than traditional cleaners that can use up to 1800 watts of power. This balance of power and efficiency ensures you get the best of both worlds every time you clean.

Dolphin Cayman Power Supply

Programmable Weekly Timer

The Cayman cleans quick, and completes its cleaning cycles in 2 hours. Its advanced mapping system ensures that cleaning paths don’t overlap and that every inch of your pool is touched by its advanced scrubbing brushes. The Cayman features a built-in, programmable weekly timer to ensure that even if you are out of town or simply forgot, your pool stays clean and ready to enjoy.

SmartNav 2.0™ Robotic Scanning

Traditional pool robots tend to wander aimlessly around the pool, hoping they’ll eventually clean everything. With the new Dolphin Cayman, there’s no hoping or wandering involved. It’s equipped with the SmartNav 2.0™ pool mapping system to ensure that it not only cleans every inch, but it also doesn’t waste time overlap cleaning paths.

Overall Rating: 4.4

Darcey Lukaszka - 5 Stars

The Cayman is AWESOME. The tracks work so much better than wheel or tires in other Bots and the snap filter in the Cayman works flawless.

Christopher Schmidt - 5 Stars

Works like a charm. Very happy. Hand-free clean pool

Douglas K. - 5 Stars

What a great little robot. We gave it a big job and it just keeps working. Very pleased. 50,000 gallon saltwater pool, with 10,000 gallon zero edge overflow tank. We just drop it in both and it cleans everything. Walks up the sidewalls, even crawls up on in pool steps and cleans them.

A.R. - 5 Stars

Cleans our 26k salt water pool with ease, easy to clean filter. Easy to use, and cheaper than the same model at our local pool store. We had a Pentair in pool cleaner that we replaced with this model. This cleaner is much easy to clean, and does a great job picking up various debris from the pool floor, it is able to climb the side walls, and occasionally can make it on to the steps. We usually put it in the pool for about 2hours a couple times a week depending on season, and need.

Bland B. - 5 Stars

Best I have ever owned. Replaced my old polaris.
