Maytronics Dolphin Cayman Review


  • More Affordable Price Point. Probably the main and most attractive reason to buy the DOLPHIN Cayman is its relatively affordable price. For the premium features you’re getting with this machine, the DOLPHIN Cayman is well worth the money.
  • Dual Motors That Supports Fine Cleaning. Another aspect of the DOLPHIN Cayman that deserved commendations is the dual motors. The 24-volt DC motors are designed to slash energy costs without compromising on power. These are some of the finest yet most energy-efficient sets of motors used in a pool cleaner yet. With them on the DOLPHIN Cayman, dirt, silt, and algae don’t even stand a chance.
  • Can Clean Several Different Pool Types. The DOLPHIN Cayman might not be the most advanced robotic pool cleaner in the market but it certainly makes up for this by being extremely flexible in terms of pool types. The DOLPHIN Cayman can effectively clean Gunite/Plaster, Vinyl, and Fiberglass pools with relative ease.
  • Lightweight Compared To Other Models.


  • Shorter Warranty Period. Robotic pool cleaners are very intricate, complicated pieces of machinery that rely on a multitude of different moving parts to work. The brightest minds went into their creation so that means it's gonna take some bright minds to fix it should something go wrong. Although the DOLPHIN Cayman doesn’t break easily, a warranty allows you to deal with any issues the unit might have by simply handing it over to the people who know best. Sadly, the DOLPHIN Cayman comes with a 2-year extended warranty instead of the 3-year warranty provided by other DOLPHIN models. 
  • Not Wi-Fi Ready. Being Wi-Fi ready means that you can control your robotic pool cleaner remotely through your smartphone. This is an extra layer of convenience that many people have come to enjoy with their pool cleaners. It seems, however, to support its affordable price point, that the DOLPHIN Cayman has opted to go without this innovative feature. 
  • Less Flexible, Does Not Facilitate Ultra-Fine Clean. The job of any pool cleaner is to effectively clean your pool, ensuring it's spotless and hygienic enough to allow for hours of swimming and fun. Though the DOLPHIN Cayman can provide a spotless pool in just a few hours, it cannot ensure cleaning that’s as quick and thorough as pricier robotic pool cleaner models. The DOLPHIN Cayman will definitely do the job and do it well, it just won’t offer the same cleaning power as its pricier big brothers.

A More Detailed Look At the Dolphin Cayman

Maytronics Dolphin Cayman Review

Pool cleaners are an integral part of any pool set up in this day and age. Anyone who owns a pool can attest that a huge hole in the ground filled with water can get dirty very easily.

Cleaning a pool, especially a large one, can take up huge chunks of your day when done manually.

Another alternative is availing of a pool cleaning service, but this can take up hundreds of dollars and isn’t sustainable in the long run.  

Pool cleaners, and the more modern robotic pool cleaners, are the natural solution to this dilemma.

Simply drop one of these bad boys in and walk away as it scrubs the dirt and grime away from the pool’s floor and walls. 

That being said, not all robotic pool cleaners are created equal:

  • Some are truly worth the money, providing superior but fast cleaning action with every use 
  • Others talk a big game but show very little for it

Which category does the DOLPHIN Cayman fall under? Read on to find out!

Dolphin Cayman Features:

Let's examine some of the features in greater detail! 

Adjustable Cleaning Time

A common feature with many pool cleaners is that you can set a weekly cleaning schedule that’s tailored to your liking.

With the built-in Smart Weekly Timer, you can control when your robot operates without lifting a finger.

This means that you save on both personal energy and electricity with a machine that runs only when it needs to.

This model offers you a selection of 3 settings: every day, every other day, or every 3rd day.

Energy Efficient

Related to the point above, the dolphin cayman only operates when it needs to, consuming less energy than the pool filters that run 24/7.

Another feature that makes this option energy efficient is the dual 24-volt DC motors designed specifically to slash energy costs.

Traditional robots can use up to 1800 watts of power, but Cayman delivers at an impressive 90% less energy use.

A benefit like this cannot be understated these days.

With rising energy prices, and concerns over high energy usage clashing with sustainability efforts, having a pool cleaner that’s easy on consumption goes a long way.

No Hoses Required

Like with many others, robotic pool cleaners do their job without needing any hoses or pumps.

This minimizes the likelihood of your sifting through tangled wires to set up your pool cleaner.

Like with most new robotic pool cleaners, the DOLPHIN Cayman sports internal filters that collect the dirt, needing only to be emptied after every or every other cleaning cycle.

Powerful Motor

The dual 24-volt DC motors facilitate 4000 GPH of suction power. This puts it miles ahead of many other robotic pool cleaners in the market right now.

It can scrub off minute dust particles with ease and leave your pool sufficiently clean in just a few hours.

You can even let it run during the night to not interrupt the family’s splashing fun during the day. With these kinds of motors, the DOLPHIN Cayman can clean pools of up to 33 ft. in size.

2-year Warranty

The DOLPHIN Cayman comes with a 2-year warranty period for spare parts, servicing, and maintenance.

They will also provide you with a completely new unit should there be any factory defect with the one you purchased. A nice little add-on should anything go wrong.

Other notable Features:

  • Being ergonomic in design and extremely light, weighing in at only 14 pounds, this is a sleek-looking robotic cleaner that’s not difficult to carry around. 
  • Compared to older robotic pool cleaner models, the DOLPHIN Cayman is 30% lighter.
  • The continuous tracks of the DOLPHIN Cayman make it easy for the robotic pool cleaner to climb up and clean the walls of your pool. This, long with Hyperbrush Scrubbing, ensures everything from dirt to algae is removed without damaging the surface of the pool.  
  • Another great little feature is the use of CleverClean Technology which allows it to scan your swimming pool and use advanced algorithms to efficiently clean the floor and walls without letting obstacles get in the way.

Dolphin Cayman Review & Final Verdict 

Our Rating: 4.2 / 5

And that was the review of the DOLPHIN Cayman.

If you’re looking for a quality robot pool cleaner that won’t cost you an arm and a leg, then this particular model is one of your best bets.

Though it should be noted that to achieve this low cost, the DOLPHIN Cayman had to do away with the more innovative features supported by other DOLPHIN robot pool cleaner models. 

There was a time when a robotic pool cleaner, even the most advanced ones in the market, weighed so much that it felt like a workout to simply get into the pool.

In those days, one often wondered whether it wasn’t the suction that kept the pool cleaner on the floor but its own weight.

And don’t even get me started on getting it out of the pool once it’s done (hint, it's super easy)! 

The DOLPHIN Cayman is one of the lightest models of robotic pool cleaners available. With this unit, you can simply pick it up and drop it into the pool without breaking a sweat.

Although a lot was taken out of this DOLPHIN model to make way for lower costs, it still provides a great cleaning job that’s often better than most other robotic pool cleaners out there.

If you want all those extra features though, like being remotely controlled and a longer warranty period, then this likely isn’t the model for you.

But if you’re looking for an energy-efficient, uncomplicated, and affordable robotic pool cleaner that does what it says it does, then the DOLPHIN Cayman is the right choice.  If you want something a bit more affordable, the dolphin e10 is worth considering.  It's not without fault, but we think the price is justified and it works well enough. 

Overall, we definitely recommend the DOLPHIN Cayman for purchase, but if you don't feel it's for you, check out our #1 choice below!
