  • Question
    Why won’t this cleaner climb the walls?
    Answer
    The above ground robotic pool cleaners are designed specifically for cleaning the FLOORS ONLY.
  • Question
    What are the voltage requirements for the Dolphin power supply?
    Answer
    The Dolphin requires a standard 120v outlet for power.
  • Question
    What are the ideal operating temperatures for my Dolphin cleaner?
    Answer
    Dolphin robotic pool cleaners are best used in temperatures between 43 and 93 degrees.
  • Question
    Should I remove the Styrofoam from the motor unit?
    Answer
    No, do not remove, this is not packing material. These help the Dolphin with buoyancy within the pool.
  • Question
    My white climbing rings are dented, are they damaged?
    Answer
    No, the indentions on the rings are normal and due to the product settling during shipping. The rings will reshape once saturated with water.
  • Question
    My Dolphin does ‘wheelies’, is this normal?
    Answer
    Yes, the Dolphin maneuvers around the pool by starting and stopping the impeller. This allows the cleaner to make precise turns, which simulates the ‘wheelie’ appearance.
  • Question

  • Question
    Can you leave the Dolphin in the Water?
    Answer

  • Question
    Can I purchase a Dolphin pool cleaner and use it abroad?
    Answer

    Dolphin pool cleaners purchased in the United States must be operated in North America in order to retain the warranty rights. Using any Dolphin pool cleaner outside of North America (that is purchased in the US) voids the warranty service agreement.

    Answer
    The power supply unit is an electrical device which must be protected from the elements. When in use the unit needs to remain dry. Do not submerge the power supply unit in water as this will damage the internal components.

    Jon Varnes

    So easy and so nice to just be able to throw the dolphin in the pool and let it go!! The best way to clean the pool with no effort but plugging it in. It’s so nice to just being able to throw it in and go do something else till it’s done. Also so easy to clean, just spray out the basket and it’s ready to go for the next time

    5 out of 5 I love it!!!

    Jean tucker

    I love my vacuum! My pool is under some trees and the vacuum picks up everything… it is soooo much easier than using my pool vacuum that uses the pool filter. With the dolphin’s self contained collection bag, which holds quite a bit, my sand filter does not need to be cleaned as soon often. And I think the dolphin cleans better.

    One enhancement, my husband wants a joy stick to tell the dolphin where to go….

    Bilal

    It has a very nice design, not like others where they are glued together and the glue come off. It also has good suction and picks up a lot of dirt. I wish it comes with the Very fine basket.

    5 out of 5 Perfect Bottom cleaner

    William

    Works great, really pulls all the heavy debris up such as leaves and dirt. Will also climb part way up the wall! Easy to clean out debris that has been picked up. For the price it is worth every penny.

    5 out of 5 Happy for $450

    Dale

    This robot cleans entire bottom of our 15×24 pool & goes around the ladder. Living in Florida we wanted something that picks up all the sand from everyone’s feet & the smaller leaf’s. Easy cleaning basket pops out the top & it will come apart for spraying off with the hose. After 2 months we are happy so far!

    5 out of 5 Best automatic cleaner I've ever used

    John

    This cleaner is the only one I’ve ever owned that will actually vacuum the entire bottom of my pool. Even around the edges . It definitely gives you the same results as a hand vacume. It’s expensive but totally worth it in the long run.

  14. larry rosencrans

    3 out of 5 Not right the first time.

    larry rosencrans

    I purchased the Dolphin S 50 to save me the physical time to clean my pool. It will pick up most items in the pool but will not collect the finer particles. The pool looks great until an hour or two later and the particles have settled back on the bottom of the pool. I then have to manually vacuum the pool. I talked to the business I bought it from and they told me I could purchase an ultra fine filter for $100.00 that “might” pick up the fine particles. I did not know this when I spent $500.00 on the S-50 so I would not have to manually vacuum. They have basically said too bad. I can not afford to buy the ultra filter not knowing if it will solve the problem knowing they will not back up the sale with a refund if it does not.I know this because when I was looking at purchasing the S-50 I was told Is a great performer, no complaints, if your not satisfied bring it back”. I did and was told I could not return it once it had been in the water. How was I going to know how it worked if I did not put it in the water? Now they want to sell me a better filter basket. You should sell it with the ultra fine basket to begin with. I feel I have wasted my $500.00. This robot pool cleaner does not do the job Right The First Time,or the second, or the 3rd. Very disapointed.

    Product was great while it worked. I’ve been trying to contact the company for 1 week, leaving phone messages and email messages. Still yet to have been contacted. My product is still under warranty. My pool is in desperate need of a vacuum cleaner that works!

  17. Shawna S.

    2 out of 5 Extremely disappointed

    Shawna S.

    I spent almost $700 on this machine. I bought the s50 model on June 13, 2019, which is the one rated for my above-ground pool. I realized shortly
    After that the robot would run for about and hour and then just shut off in the middle of the pool, despite the fact that the pool is no where near clean yet. I found out today that the unit has a 1.5 hour cycle and then it stops and has to be turned back on again. That isn’t near enough time to clean the pool, so I have to run out there every hour or so and then turn it off and back on so the thing will keep running. It is so inconvenient. I would have never bought the unit if I had known that.
    I wish I would have just bought a newer version of my $99 Kreepy and left it at that. The old cheaply also picks up diet and debris much better. This one kinda just runs over it and spits a lot of the finer dirt and debris right back out the top of the machine. Supposedly there is another basket you can buy for another $100 that’s picks up better but I have zero confidence in anything to do with this company or this machine at this point. BUYERS BEWARE!

    4 out of 5 Clean pool, No work

    Harry Cottrill

    We tired of the crappy “lady bug” pool vac that came with our pool and ran off the pool pump.
    Decided to go with the Maytronics self powered pool vac. We’ve had this vac for a year now. Simply plug it into a 120 outlet and it’s converted into safe low voltage power which doesn’t rely or bog down your pools pump.
    This vac has its own rubish collect filter bag.
    We just set it in and forget it !!!
    So far, so good. Highly recommended
