  • Question
    Why can’t I access all the features on the power supply?
    Answer
    The power supply is a universal unit for multiple Dolphin cleaners. Your Dolphin is programmed with specific features for your individual Dolphin cleaner.
  • Question
    When to use the Spring Filters versus the Ultra Fine (corrugated) filters?
    Answer
    This Dolphin cleaner is shipped with the spring filters installed. The spring filters collect large debris (such as leaves). Inside the box are the Ultra Fine filters (corrugated) which collect the small debris (such as dirt or sand).

    The Dolphin requires a standard 120v outlet for power.

    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
    Can you leave the Dolphin in the Water?

  • 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.

    Robert Ferguson

    I’ve spent 18 years fiddling ariund with every pool vaccum on the market. However, since I purchased the Maytronics Active 20 my pool has never been so clean! After the winter my pool is still algea free today, April 19, 2018.

    2 out of 5 Unsatisfied with the Active20 and tech support suggestion did not help.

    Andrew Crouter

    I have a freeform pool and this bot does not reach everywhere. Tech suggestion was to start the bot in different areas or send back to manufacturer (not for refund mind you, but for troubleshooting). While starting the bot in different places might be an option, it did not work, and am so frustrated I spent 1K+ on a bot that might need to run multiple cycles to get 100% coverage (which doesn’t work). Kinda feel duped. I wish maytronics had more control over their authorized dealers and worked with them closer to resolve troubleshooting and returns.

    Tip – if there is a brick and mortar store in your area, buy from there and ask about the return policy! You might have better luck trying to return the unit or even get credit for a different one. What I really wanted to do was return the Active20 and trade up for the Active30 because the mobile app supposedly allows you to locate the bot where you want after it has geomapped your pool. Since i didn’t buy from a brick and mortar store, that doesn’t seem to be an option. 100% satisfied seems to be a marketing ploy at best, and any issues need to be resolved with your retailer unless you want to ship the unit back.

    5 out of 5 Love my Dolphin Active 20!

    Tom Grider

    I absolutely love this thing! Easy to use, easy to clean, does a great job of cleaning my pool. The hours it has saved me from connecting hoses and manually vacuuming my 28k gallon pool is priceless! I drop Flipper (as I affectionately call it) in the pool in the morning and go enjoy my coffee. After about 2 hrs I’m ready to swim, although I’ve been in the pool while it does its thing. I’m always amazed at the amount of fine sand/dirt it removes. One suggestion for future models would be a swivel where the power cord is attached to the machine to make rolling the cord easier. Bottom line…can’t imagine being without it!

    I love my Dolphin 20 it makes cleaning the pool so much easier and faster. I put it in the pool and forget about it until I’m ready to get in the pool. The filter is so easy to clean also. I would recommend this product to everyone!

    Last year was so much easier to keep my pool clean with my active 20. Just opened the pool this year and it is hard at work getting the pool ready for this year. Very happy with this product and can highly recommend it.

    Scott

    This cleaner makes cleaning so easy. It does a great job. My only negative comment would be the cord. It tangles constantly. I followed the recommendations of laying it out in the sun. But it tangles again after a few minutes of use.

    5 out of 5 Awesome Cleaner

    Bob Lewis

    I own a Viking fiberglass pool with toe ledges, seating ledges, and stairs. This robot cleans it all! I was very hesitant to buy one due to not knowing if it would climb over the toe ledges on the walls and continue on cleaning the wall to the water line. It does it perfectly. Everything about this unit is well made and convienet to use. I couldn’t be without one now. Thanks for such a great quality product!

    4 out of 5 Its ok for the price point. I would have spent the extra cash for the Bluetooth enabled on if I knew this one would miss things

    Guy S

    It cleans about 80% of my 18×36 rectangular pool within a 3 hour cycle but tends to leave obvious chunks of junk on the bottom of the pool. I tend to question this” Smart sensor” technology that they claim is built into the unit. Wonder if its just a blinking light to make you think its a sensor.

    5 out of 5 Amazing debris pickup

    Kurt

    I’ve had my Active 20 for a year now. With two minor exceptions, it has been very positive. It cleans up my worms and leaves easily but where it really shines is the dust-like debris that the pleated filters capture. It is amazing the amount of funk that washes out of them.

    The two minor items are that the cord twists, and I remove and untangle it after each use so it’s not accumulating twists from multiple uses. Howeve, I believe this has been addressed with a a swivel cord on 2018 models.

    Ours does also occasionally timeout on the long bench we have on one end of the pool. It happens about 20% of runs. But I’m often around and just push it back k in if it happens.

    I do tend to run back to back 2 hour sessions to get a really full/solid coverage of our 18 x38 pool.

    Overall it has been great!

  15. Robert Murray

    3 out of 5 Programming Issues

    Robert Murray

    Overall, Dolphin A series Active 20 does a great job cleaning pool; however, it cannot be programmed for weekly cleaning schedule as indicated and retailer cannot provide a reason for this apparent failure. Sometimes the unit cannot be turned off unless it is unplugged from the power source. Sometimes it just keeps cleaning forever and never gets to the end of a cleaning cycle and again, cannot be turned off utilizing the on/off button.
    Had a considerable amount of difficulty in getting the unit registered and am still not sure all the required information was received by Maytronics. Everything we had was sent but confirming e-mail indicated not all was received. Very frustrating!

    2 out of 5 WORST POOL CLEANER

    Cindy Schmidt

    It does not scrub the algae off like it claims. The cord is all twisted up and I lay it in the sun like they say to do but it’s a pain. Does not go to my shallow end to clean. I had another brand for 16 years that is refurbished and still does a better job than this . HATE IT

    4 out of 5 BOUGHT MINE THIS SPRING

    Lianne R

    and I am super glad I did. I have an inground pool and since my husband passed away pool cleaning by
    myself was a challenge and I hated to keep calling someone to come and help me set things up.

    Now that I have Miss May (my pet name for my active 20) she and I have no problem keeping the
    pool sparkling…and it has been a pretty hot Summer.

    Girl power !

    5 out of 5 Great unit.

    jandk.s28

    I waited till i had this unit for an entire pool season before i wrote a review. I found it worked extremely well. It climbed my pool walls and bench seats with ease. Never ever getting stuck. No issues (except for winding up that power cord but that’s minor). My pool hasn’t looked this good ever. I don’t know if it’s because i used this every other day but i never had an algae issue all season and we had some extremely hot weather this summer up here in Southern Ontario. Wish i had bought it years ago.

    I had the MX8 for almost 4 years and was initially happy with it but it kept getting jammed with larger leaves. I went today to look at alternatives and bought this one. I am ecstatic!! The time and speed of it, the ease it picks up larger debris. Well worth every penny!!!
