Maytronics Dolphin S400

The wifi receiver is a cheap unit and requires the unit to be within 1m of the wifi access point, which even when it is does not connect. When it randomly does connect the robot does not work. Not worth the money, do not waste your money. Show details

I've seen lots of positive reviews for this pool cleaner. They are either fake reviews or I was just unlucky enough to buy a dud machine. About to take it for 2nd repair in 10 months since I bought it. Poor cleaning performance, poor wifi and Bluetooth connectivity, which regularly drops out and won't reconnect. Add to that cheap plastic internal… Read more

components that have broken several times...all in all a very disappointing pool cleaner which has put me off Maytronics/Dolphin completely.

Disappointing – I tried hard to like the S400 for well over a year now, but there are just too many annoyances, especially for a top of the line machine. I'd expect this of a $300 machine, not a $3000 one. It does a reasonable job of picking things up. But we have a large flat step at one end of the pool (ca 2mx1.5m, 50cm height) and it fails to climb up and… Read more

clean that 95% of the time.... So I have to manually brush that end of the pool (and yes I contacted support, and the conclusion was the robot just isn't that smart/good).

What I find most frustrating is the usability though. The app is very slow and buggy. I can't integrate it with google home. I think it works with Siri, but I have so many problems keeping the wifi connected, that I've given up.

If you want to clean the pool, just be prepared to wait a minute or so for it to load everything before giving you the option to hit clean... may as well walk to the filter and hit the button.

As mentioned, it constantly loses wifi connectivity and it will never reconnect on its own. You have to go through the whole painful setup process again. Most of the time that process does not work. I have a $20 wifi plug right next to the Dolphin power supply - the wifi plug performs flawlessly, and I reckon I've had about 10% up time on my Dolphin over the last 18 months. It is such a pain to try to reconnect it that I've basically given up and resort to using it as a dumb machine. Finally the anti-twist cable seems to only partially work... my machine still manages to tangle it all up, which then affects how much of the pool it cleans....

I'd be very happy with this machine if I paid $300 for it, and was not promised so much capability that clearly doesn't work. In this case, paying premium pays for premium marketing, but not a premium product.

Fantastic performance – I tried a few other models before Maytronics and I have to say my Dolphin is awesome - its cleans by pool better than before. Dolphin really is the best on the market, my pool has never looked so clean Show reply

Really quick cleaning – I purchased online and found the 'choose my robot' tool helpful, delivery was quick from my local pool shop and the Dolphin itself is great - has cleaned by pool meaning I can now chill out by the pool and enjoy! Show details ·  1

best and easy to use – Surprised how well it performed. We have always has suction cleaners and decided to upgrade to a robot. We tried a few and found the Maytronics Dolphin to be the best. Great performance. Really easy to use and our kids have named it Eddie! Thanks Maytronics! Show details ·  1

Wow! We upgraded to an S400 and its great! – We decided to upgrade from a Zodiac pool cleaner to a Maytronics S400 and wish we did it earlier. The S400 is awesome, it has cleaned our pool so much better than any other cleaner. We did also trial a few others. The pool store said that the Maytronics were number 1 for a reason and they really are! Show details ·  1

Bubbles is brilliant – “We previously had a Zodiac but the pool shop recommended the dolphin for my pool. My daughter has named it bubbles and loves watching it come to the top and scrub along the waterline. Our pool is as clean as it has ever been and the s400 has filtered the sand in the pool for the first time. We love the double filter for leaves and sand. Great design and wow so quiet. BUBBLES IS WELCOME IN OUR FAMILY!!!” Show details ·  1

Dolphin S400 – Great product easy use & does as advised. Great to use remote with pickup feature wouldn’t buy a unit with out this feature. Great anti tangle cable and pick up fine sand from the pool bottom. Show 2 replies
