Maytronics Dolphin S 300i

We have a large pool and neighboring trees drop leaves & twigs into the pool. This unit although expensive cleans all this debris without any trouble.
After an initial issue which was sorted by Maytronics and the agent extremely promptly this unit has not missed a beat. The unit climbs the walls of the pool then moves sideways cleaning along the waterline as well as the floor and within a couple of hours of setting the unit up the pool is spotless

Have owned the pool cleaner for 7 months now and hasn't missed a beat, pool is surrounded by trees so lots of leaf litter and dust, so far so good, easy to use compared to setting up a suction cleaner, just hoping for the high cost of the unit it goes forever.

We live in a very heavily treed area so our pool is constantly filled with debris from leaves to small sticks, the Dolphin 300i cleans it all up with ease, it very easy to empty and clean the filters, we set and forget.

Bought S300i 4 months ago and pleased with it so far. It's expensive but I've had 3 other cleaners before this one (in 15 years) and this is the best so far. The best thing is that it's not connected to the pool pump so the pump can run without the extra load of a cleaner. We have a large pool that collects a lot of leaves so I have to empty the basket 4-5 times a day until it's cleared out - but that's ok as I had to do that with the pool filter basket anyway. Does not clean the steps - tries to but doesn't succeed so I usually vacuum them manually. You can do it with the app but it's a bit of a hassle and the last couple of times I tried to use the app it didn't work- not a major problem to me though. So far so good.

Love this pool cleaner. Thought our pool was clean with our old cleaner but couldn't believe the difference when we got the maytronics cleaner. It is now crystal clear all the time. never have anything in the pool it picks up everything.

My Dolphin has taken over all the work I used to have to do myself or pay a pool guy to clean the leaves and debris from overhanging trees.

It is just set and forget and clean the basket every so often

Made some pretty good decisions on pool equipment before but this is not one of them. Have had the unit for 2 years and 3 months and in that time the controller has had to be replaced on site by a rep, have had problems with the app which were resolved and the power cable had to be replaced under warranty because it was faulty. Now I have had to pay 325 dollars to have an impeller fixed for a unit that was cleaned weekly and it was cited as maintenance. I would say more likely poor design. When it cleans it cleans well but it comes at a cost. Poor product and clearly badly designed

We have a large vinyl pool with a deep end, the debris in the pool was gum leaves and the cleaner worked pretty good......while it worked. Every season since we bought it three years ago we've had to send it back to the supplier for repairs as it ends up turning in circles and doing nothing at all. Every year the same problem, now Maytronics say they will not fix it anymore nor will they do any refund at all. Were left with a $1500 lump of plastic that doesnt work. The cleaners work ok when they do work, but the support will not be there for you when it breaks, and it will break.

This is my third Robot. Starting with the Zodiac V3 - good, then an AstralPool RTX - better, and now i have the Maytronics S300i. Obviously they all get better with evolving technology but the S300i really is miles ahead of the pack. Great smart phone connectivity and a really effective cleaner. Been in the pool for 8 months now which i know they say is not the right thing to do but what evs... Been tracking around cleaning the pool without fault, i dont use the timer any more, i just turn it on with my iphone when i see the pool is dirty from the bedroom window!! So cool. And the little light on the front makes night time running cool also...
Very good product so far..

Very disappointed with this pool cleaner. Was told how good and reliable they were by the supplier, however had had trouble with it after 12 months not cleaning the pool properly and stopping intermittently. When I rang and advised of the issues was told it more than likely my pool walls and a dirty filter on the unit.

Now it is out of warranty it has stopped completely and has issues that require a new drive motor. Very disappointed Maytronics as I believe the motor has been on the way out whilst under warranty.
