Dolphin Active 20

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!

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!

Had the Dolphin active 20 for two seasons. Had issues with unit not cleaning shallow end of pool. Took it back to exchange unit. Second unit did the same thing! Just would not clean shallow end..

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!

This product does what it is designed to do. It work great as long a it is kept clean.

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.

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!

Best time saving expense I’ve ever made.

Cord ravels up and it takes forever to unravel. I purchased new from authorized retailer and it stopped working in less than four months.

My previous Dolphin DX4 lasted only 3 seasons. Bad motor and bad cord.

This active 20 model doesn’t pick up debris as well as the DX4 although it was in the same price range (I paid about $700 – $800 for New DX4 in 2014).

Also doesn’t get the crevasses very well either.

I have four weeks of summer left and am planning a 16th birthday party in two weeks with no way to clean my pool.

I wish there was a better option in this price range by a different manufacturer.
I also submitted required documentation for the rebate to maytronics online and the rebate never came.

Buyer beware!

I have a kidney shaped 18,000 gallon pool. Deep end is about 7.5 feet.

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 finally got rid of my aqua crap, this is my first week using it, it’s so easy to clean. Pool looks great

The Dolphin Active 20 is great! Picks up almost anything and cleans and scrubs the bottom and sides amazingly clean!

Great machine. Just turn it on and let it go. I vacuum once a week and brush once a week. Enjoy the pool much more since I have more free time. Worth every penny.
