Poor after sales support

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.

Probably the Best Robot available

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..

Thanks for your review, please get in touch if there is anything we can do to help.

WOW - An expensive boat anchor.

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.

Hi Matt C, we at Maytronics are sorry to hear about this experience. We would like to look into this to see how we can help turn your experience around. We will send you a private message to connect.Thanks will wait to hear from you.Hi Matt, your message should be in your Product Review inbox.


i bought this 9 months ago as i was sick of using a basic suction cleaner which would jam up with certain leaves which are unfortunately common in my pool. My alternative was using vacumn hose which you can imagine is a vertitable PITA. What a labour saver! And it keeps pool clean. Mind you it is best/advisable to take it out of pool after use and rinse filters every time. I also rinse whole machine given my pool is salt based. As to leaves it can suck up quite a few in its collection system due to the suction, of course if you get a lot of leaves you can pick some up with scoop to makes easier.It has a 2 year guarantee btw.
I looked at a few at home show and while many promise to work if you get problems backup is important and not all are easy or amenable when it gets to that situation.

Spotless pool, great investment

I was looking at getting a robot for the pool for quite some time. It's a relatively new pool (less than 2 years old) so i did my research, and with some advice from my local pool store, i ended up getting a Maytronics s300i. I'm a pretty fussy guy, i like my pool spotless, and the little robot makes it sparkle every clean. I've been using the unit since November, and i couldn't be happier.

I've sat down with a beer on more than one occasion, just to watch the little guy race around the pool.

The filters are easy to clean, and this one is a lot lighter than the other ones i was shown in the store. The timers are easy to set, and the phone app means i can change the timers and even turn the unit on from the livingroom! The instructions were easy to understand, even if they were a little simple, and the whole thing was in the pool and working in about 10 mins, so it's very easy. The kids named it Toby after our old neighbour's dog, so it's even got a name.

I followed the poolshop's advice, don't watch it clean the first time, becuase it's meant to be learning the pool, and it looked very dumb the first clean. But once it learned the pool it started zooming around like a champ.
Its expensive, but totally worth it. 5 stars.

Hi, I got a brand new S300i dolphin 6 months ago. It’s worked very well upto now when I can’t seem to be able to select the cleaning mode & hence does not work. It does not work via the app and does not work from the control panel either. Please help
