This cleaner never worked well
Unfortunately this cleaner has been a frustrating experience. It never cleaned all the pool and spent most of it's time in the deep end. The cartridge type leaf catchers have a small capacity and they kept bursting open inside the unit. The impeller would frequently get clogged. It was too heavy to easily take out of the pool. Numerous parts failed: the brushes, the cable, the cartridges, the s clips holding the cartridges closed, the power supply switches and now it has stopped working completely. The parts are so expensive it is not worth rebuilding it. I thought I was buying a top of the line cleaner but it has been disappointing.
Purchased for $1,800.00.
This is a great product and worth the money. Perfect for a fully tiled pool. Highly recommend https://www.pooltronics.com.au/ to purchase any Dolphin product as they really spent time to help select the best product for our pool and even did a person delivery and demo to talk through how to use it.

This is the second season that we've had this cleaner. It does a really good job, but the wonder brushes are worn out already.
I was shocked to find out that it costs over $100 a pair...and you need two sets..!
That's a lot of money in maintenance costs..

Very good, but disappointing user manual
EDIT, please read all the way through for an updated happy ending.
I originally bought a Zodiac CX35 online and was so excited to use it for the first time. Found I was happy enough until it broke within 7 days.. got an error code and it refused to move. Sent it back for a refund.
This time around I wanted to do a little more research before buying something and all roads pointed toward the Dolphin because it was tough, dependable, had finer filters and was nav intelligent apparently. First thing I noted was that it has two filter canisters n...ot just one! Where no one ever actually mentioned online whatsoever so that was a complete surprise. Also has two types of changeable filters, one I'm guessing 100 micron and a finer type. Very cool. The Zodiac only had a 200 micron (or pay an additional $80 for 100 micron) where silt would blow through back into suspension clouding up the pool. The other thing I noticed was the Zodiac impeller was actually right in the middle of the filter basket, suspect to damage ... whereas the Dolphins is independent and won't be damaged by debris spinning through filtration. (Dolphin impeller after all filtration has been completed, Zodiac right in the centre of the filters) It's definitely built tougher, which is good and seems to do a decent job of navigating the pool. I do notice it climbs the walls in the same three or four spots and can't quite make it up the steeper starting corner slopes where none of the rollers or tracks make forward contact but no robotic cleaners would. (fwiw I have a fibreglass pool and bought the WB model with foam rollers). It doesn't seem to get to the waterline much after the first few minutes, as soon as there's a little bit of matter inside the filters it stops climbing and slips as it tries to climb up before reversing back down with even the 100 micron filter installed, and I mean miniscule amount of debris in the filters (I thoroughly clean these each time), it just seems to become too heavy but so did the Zodiac as well, maybe all robotics do this? I've tried adjusting the float positions but it hasn't seemed to make a difference at all. Is it possible because my fibreglass pool is sprayed blue the shop should have sold me the CB model? In the manual it states: WB for tile and ceramics, online states also fibreglass so who knows It does pick up everything, but only if I sweep the silt down to bottom off the higher ledges. It does knock some down on it's descent if it can climb the particular area which I can tell was cleverly and purposely designed. It leaves a few small piles of silt on some of the curves/corners and stairs where my pool is strange and street shaped but I can live with that, no robot would be able to get that, it's only very small amounts.

Great cleaner with easy to empty filters!
I have a large 80,000 litre Pebble Crete pool and it cleans it perfectly every time. I put it in once every week or two as required. The cartridge type filters are easy to remove and clean.

Makes the resort lifestyle easy!
What a great cleaning unit the Dolphin M400 is! Easy to use, easy to maintain and it has its own trolley to relax in when it’s not hard at work cleaning the pool.
Gets right up to the waterline and steps.

Seems like a winner
Early days but very impressed so far. Picks up much more than our previous suction cleaner. Seems very easy to operate and emptying the waste compartments is an absolute breeze

Amazing Product M400
I purchased my Matronics M400 yesterday from Brisbane Pool.
My previous M400 had died after 7 years of solid service without ever having one fault. My new M400 is perfect and does such a wonderful job keeping my pool sparkling clean. I have lots of trees and leaves, but this model is absolutely perfect and does a wonderful job cleaning floor, walls and waterline. Its a really good quality build and I would recommend anyone to buy this model.

The Maytronics M400 is very good at cleaning large and small debris equally. It also does a good job at picking up the fine dust from the bottom of the pool. I am happy with the product.

Great cleaner that reduced cleaning needs
Easy to use, simple to clean filters, just plug in and it does the job, in addition cleans the walls as well, removes fine debris from floor and walls. Good warranty as well

So east to use!
We love our new M400 pool cleaner. It is so easy to use and does a great job cleaning the floor and walls of our pool! Love the storage caddy too.
Filter options vs function
Purchased the M400 4 months ago, I asked the retailer which one I should buy regardless of cost. I wanted the most reliable and guaranteed to clean all surfaces including walls, regardless of cost. Was assured the M500 or M400 (if I didn’t want the programming / App features) is the top of the range and the best option. I wasn’t told about or offered the 600M, found out later it was out of stock at the time and obviously they wanted to sell me what was in stock.
The M400 does a great job at cleaning the floor, but like many other reviewers, it ...

Never have seen the pool so clean in my life!
I've been using a suction pool cleaner for a while, and I've gone through about 5 of them. They're annoying to operate and restrict the features of your pool's pump system. I then came across the Maytronics Dolphin M400. It was the first time I'd seen a robotic pool cleaner in action, and I thought it was pretty amazing. I took a free demo and was amazed to find my pool sparkling clean when it was finished. The robot isn't cheap, but it's worth it. I highly recommend this product.

I love our Dolphin, can't live without it!
We had actually ordered a different robot pool cleaner when we built our pool until my friends told us about the Dolphin. They had done a lot of research, so we decided to change to the Dolphin Supreme M4 and I'm so glad we did!!! It climbs the walls and spends a couple of hours vacuuming the pool, we usually chuck it in the water at night after we've finished swimming and it goes about it's job cleaning the pool so we get up in the morning and it's sparkling clean, ready for us to swim!
It's a fantastic product that cuts out soooo much of the work of owning a pool. I now recommend the dolphin to everyone I know who owns a pool!!!

Dolphin left holes in liner
Have only had my dolphin m400 for 1 year. This year our pool was losing water, pool leak specialist found 2 holes where wall and pool floor meet both same size. He asked me what I use to vacuum, I showed him my dolphin and he informed me that I was the 3rd person that used the dolphin that had holes. I have vinyl liner , and I’m not sure why this would be happening.
Have tried contacting Maytronics and have not heard back. Not happy having an expensive vacuum I am affaird to use for fear of more holes in liner.

Questions & Answers
What would stop one side of the brushes from moving?
Thank you for reaching out.
There may be an obstruction in the track that can cause this from happening or it may also be an issue with the drive motor.
If you are able to call our Customer Care Team on 1300 693 657 opt 2 one of our team members will be able to go through some troubleshooting with you over the phone.
I have an M400 which is 4 years old. I have changed all of the brushes and the white pads. Since I put it back in the pool the robot doesn’t seem to scan the pool correctly. It does stop now and again seeming to scan but doesn’t turn 90 degrees. It then just moves back and forth to each side of the pool. I have looked at all of the brushes to check if there is anything obstruction but there is nothing at all.
Can you tell me if there is a problem with the electrical scanning printed circuit or anything else to help me .?
I have a M400. I changed the climbing rings, and also noticed the drive brush had a broken/stripped gear and bearing assembly on one side. I bought a new piece and installed it in the dolphin. it does good on the bottom and half way up the side but when it gets to the vertical angle of the pool one side runs faster than the other. What can I do to fix this? it is probably why the gear stripped out last time.
