  • Question

    The Dolphin requires a standard 120v outlet for power.
  • Question

    These are to protect the climbing rings during shipping. Please be sure to remove before the initial cycle.
  • 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
    Is there another filter option for this unit?
    Answer
    Yes, there is an Ultra Fine filter basket available. The part number is 9991460-R1.  Please contact your dealer for pricing and availability.
  • Question
    How do I remove the Dolphin from the pool?
    Answer
    Using the floating cable, pull the robot to the edge of the pool. Grab the handle and remove the robot from the water. Do not pull the robot out of the water using the cable. Place the pool cleaner on the side of the pool to allow the water to drain.

    Answer

  • Question
    Can you leave the power supply out in the weather?
    Answer
    The power supply is water resistant but not waterproof. Please cover the power supply if inclement weather approaches. Do not leave the power supply in standing water. Do not allow the power supply to be submerged in the pool.
  • Question
    Can you leave the Dolphin in the Water?
    Answer
    It is safe to leave your Dolphin cleaner in the water when not in use. However, (when adding chemicals to the pool) please remove the Dolphin until the proper chlorine and PH balance are obtained.
  • Question
    Can I use my Dolphin pool cleaner with an extension cord or surge protector?
    Answer

    The Dolphin is not designed to be used with an extension cord. There are many different types of extension cords and we do not recommend using one. However, it is safe to use a surge protector with the Dolphin. This will help protect the Dolphin from surges in power such as thunderstorms.

  • Question
    Can I use my Dolphin in an Infinity pool?
    Answer
    Not all Dolphins are suitable for infinity pools, please contact Maytronics directly or your local Dolphin retailer for information regarding the models that are suitable for this pool type.
  • Question

  • Question
    Can I purchase a Dolphin pool cleaner online with warranty service?
    Answer
    Maytronics offers several pool cleaners both via brick and mortar stores and via internet dealers that include warranty rights. Please refer to the ‘Residential pools’ section of our website for our product listings.
  • 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.

  • Question
    Can I leave the power supply unit outside in the elements?
    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.
  • Question
    Are Dolphin pool cleaners safe to use when I'm swimming in my pool?
    Answer
    Dolphin pool cleaners are safe to use for the general public, however, (for safety precautions) we do not recommend swimming while the cleaner is in use. We also do not recommend leaving the cleaner in the pool for long extended periods of time.*

     

    *Please note the pool cleaner may stay in the water when using features such as the weekly timer for automating cleaning when you are away from your home.

    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 Strong and powerfull

    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 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….

    4 out of 5 Clean pool with no effort!!

    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

  9. Harry Cottrill

    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
