What we like about the Dolphin Cayman robotic inground pool cleaner is that it is energy efficient, and therefore, you will be able to save a great amount of money. We don't like that it can be used only for inground pools.
Measuring only 22” by 13” by 18” and accompanied by a feather-like weight of 13.8 lbs, Dolphin Cayman is easily maneuvered around both on land and in water, and never becomes an obstacle while enclosed. It proposes an elegant casing in beautiful neutral colors that ensure compatibility with a wide variety of pool styles. The front-positioned, incorporated handle assures the cleaner will never slip through your fingers, whilst the lengthy cable, 50’ gifts leeway for the device to reach pools up to 40’ long. Also equipped with a swiveling function it will never tangle, regardless if there are toys forgotten on the water surface, floats, or other outdoor elements.
To ensure it can easily tackle varied areas, including vertical walls, it sports a compact rubberized track instead of wheels. This offers increased stability throughout its cleaning procedure as well as providing the robot with a strong grip on several textures. But fear not, as it will gently glide on the areas, without causing the inner lining harm or leaks. Even more, to guarantee a thorough cleanse, the dual brushrolls dislodge any dirt that might continue to be glued on the areas. They actively spin around, so they will remove twice as many algae and microorganisms than normal brushes.
The trash passes through the large intakes and ends up directly in the inner chamber. Covered with filters of fine porosity, specks as little as 2 microns are prevented from reentering the water. The chamber is easily accessed through the top-located tap-lock lid, and the cartridges are washable, for increased convenience. In case you require an ultra-fine porosity, an additional chamber with the desired specs can be acquired separately. Therefore, as the unit is completely autonomous, it won’t require any link to the pool’s skimmer, filter, or pump.
The SmartNav 2.0 navigational system orientates it underwater, ensuring it actively differentiates between obstacles, drains, and steps. Additionally, the CleverClean operational system examines the pool in real-time, learning its shape, calculating the optimum path the unit shall take to efficiently clean the basin. Therefore, it is not recommended to use it when any type of cover – solar or safety – is on, as it might impede its operation.
Its overall cycle doesn’t last longer than 2 hours, but it has plenty of time to do a thorough job. It is also an economical choice, as it requires as little as 10 cents per hour to finish its task, and through its swift water filtration disperse the chemicals equally around the basin. This not only guarantees the unit won’t raise the electricity bills, but will also help save money in the long run on water chemicals. Even more, it will ensure the water’s clarity, guaranteeing an improved water circulation, keeping the water balance stable for longer periods.
The cleaning doesn’t stop with the floor, as it is fully capable of tackling several terrain shapes, including vertical walls, up to the water edge, removing the deposits present there. It also offers its users a programmable weekly timer to keep the pool spotless whenever you wish to use it. You can program it up to for everyday use, every other day cleanse, or for every third-day routine. But don’t forget to turn off the pool alarms!
Highly compact, with few moving parts that might pose an issue later on, Dolphin Cayman guarantees long use with as little upkeep as possible. The only aspect you’ll have to pay attention to is the state of the rubberized elements, namely the brushes and the tracks. These tend to get worn out with time and they should be replaced with new ones when the time comes. Additionally, it is recommended to regularly clean the debris chamber, preferably after each and every utilization. By doing so you will prevent bacteria from growing inside the unit, as well as impede mold from forming. The manufacturer guarantees the unit with 2 years, and also provides a responsive customer support team that will answer any questions you might have. Another aspect you should keep in mind is the water balance. Test it before you wish to submerge the robot, as different water coloration or a cloudy aspect will lead to premature damage. Additionally, if the chlorine concentration is heightened, or if the pH levels go beyond the regular value, you should lower them prior to the vacuum‘s utilization. High pH means high alkalinity, so pay attention to that aspect as well, because if left unchecked, calcium deposits will appear on the robot’s filters.
All in all, Maytronics Dolphin Cayman is a highly efficient unit designed to keep any inground pool spotless. It gifts an adjustable timer for increased comfort as well as smart navigation and active cleaning for spick and span results. The filters will hold microscopic particles and will act as a secondary skimmer to your pool, since the unit works independently from pool filtration and pump.
