Owned nine months and really happy!

My experience with this pool cleaner has been different to a number of the other reviewers, maybe the majority of those who write reviews are the unhappy ones? But I have been delighted with our M400 after 9 months of fortnightly use in a smallish concrete rectangular pool. For starters the company staff really tried very hard to help me select the right unit. Secondly the unit does all it is claimed to do — climbs the walls, moves slightly horizontally when it reaches the surface, and covers the pool comprehensively in the 2.5 hour cycle. Negatives? The cable is a little inflexible to rewind, the unit is fairly heavy when lifting out of the water, and the carrying caddy is not a perfect design. I clean the filter cartridges on the unit after each use, which maybe some people do not, and that is a quick exercise. I was originally also critical of the company for the confusing marketing approach they were using in applying different badges to what was essentially the same machine for different distributors. But the M400 I have has done all I expected and more.

Do not buy if your pool is curved in shape or has curved sides!

What a mistake for the price! My old Creepy-Crawler got around to every corner of my pool, but unfortunately for me this M400 Dolphin gets stuck as soon as it hit the curves. Wheels are spinning and nothing moving!! I took it back to the retailer and complained it was getting stuck. I commented it had the wrong brushes - (they were the foam Wonder brushes(?), instead of the PVC brushes). They said no, I had the right brushes for a fiberglass pool but I had the wrong angle on the handle float. Hogwash - I adjusted it and made no difference. Now, every time I use this M400 I have to keep an eye out so when it gets stuck I have to move it to get it going again. Admittedly, the areas it does clean, it does a good job, but I always use the Ultra-fine filter cartridges instead of the net filters. I just wished it would clean the whole pool and without my intervention to get it going. The advertising for the Dolphin is that you sit back, relax and never have to worry about the pool cleaner. Yeah right!!

I am really sorry that this product is over-priced, over-hyped and over-here...in my pool.

Great all rounder

I’ve had mine for several years and it has worked really well. It cleans and filters fine silt. If you scoop majority of leaves before running it, there’s absolutely no problem. Wouldn’t be without it! Show details ·  1

Relax with a beer while your dolphin does all the work

Got our M400 a few months ago as we bought a house with a large gumtree in the adjacent property as well as a quarry behind. We were spending hours with the upkeep due to dust and gum leaves so decided to buy a dolphin after a lot of research. Would recommend it for dust/dirt and tree debris, and also for the entertainment when cleaning the water lines. The dolphin app is convenient as it occasionally needs a hand with curves, haven’t had an issues with the cable due to the swivel and the caddy is a great bonus. Show details ·  1

Hoping for a good outcome

Great pool cleaner just out of 2 year warranty. Couldn’t rate the cleaner enough!! UNTIL a week ago it stopped working!!!!! So we tested the power sockets etc at the wall and the power supply and they were all good. Still not working. YouTubed the matronics troubleshooting etc pulled it apart as per the videos and the whole electrical part was FULL of water!! Got in touch with our pool installer who was amazing and Maytronics called me straight away to tell me where to send it for a service (even though I highly doubt it could be serviced now after what we saw) luckily I videod the whole thing so they can’t tell me I’m lying. I’m really hoping Maytronics will replace this. Wish us luck!

Great Pool Cleaner

My M400 is over 5 years old now, and it’s still like new, never replaced a single part. As someone else said, the best $2000+ I ever spent on pool equipment. Show details ·  1

Pricey but does a great job

This wasn’t cheap but I’m glad I stumped up for it…does a brilliant job of genuinely set and forget pool cleaning. No regrets of not opting for an infloor self cleaning system- this is perfect Show details ·  1

Fiona C. · Dolphin M400

We installed a pool this time last year and bought the M400 cleaner with the pool. My cleaner keeps getting stuck on the corner of our bottom step. I've tried adjusting the handles to different positions but it doesn't seem to make a difference. It means I have to go out every 5 mins or so to check on it and I can never put it on and leave the house.
