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..

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...

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.

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.

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

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.

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

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.

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 ...

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.

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!!!

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.

The dolphin M400 has cleaned the floor of our pool amazingly. The pool now looks 100 percent. One of the downfalls is it will rarely climb walls or the beach we have at the entrance of the pool. Not sure if there is something wrong with it but i thought for 2100 bucks it would do this easily.

The M400 is easy to use, the filters are easy to clean, it’s runs for 2 hours straight, it climbs the walls of the pool to the top lip, it even cleans our spa including the straight edge seats! It’s perfect for people who don’t have hours to waste on cleaning, worth every cent!

Great pool cleaner it does what it suppose too and leaves my pool nice and clean when finished ( glass pebble)
I usually leave the fine debry basket in as my pool gets alot of dust & settles to the bottom, this Dolphin cleans it right up no worries!
What would of been nice on this model is an app to control manual navigation/ cycle time/ and clean modes, should be a standard thing on this model range.
Happy with my Dolphin M400.

After dealing with pool cleaners and the like which was a rip off and stressful, I finally bought a Dolphin. It is a revolution in pool maintenance ... just magic and has made owning a pool a pleasure.

My Dolphin M400 has been life changing - no more untangling the old robot driven by the booster pump and no more manual vacuuming! Easy to use, covers every part of the pool floor and picks up everything the gum and jacaranda trees can throw at it.
I leave the super-fine filters on there all the time and they’re great for collecting everything from big bits down to the fine sediments that get blown into the pool. The pool is kept nice and clean by running the Dolphin once a week and it’s east to flush out afterwards - the filters pop out and can be hosed down. Note it is a heavy unit though, especially when you first lift it out and it’s full of water.
Overall I’d highly recommend if you’re in the market for a new robot!

Our pool builder recommended to use a robotic pool cleaner on handing over the pool. They in fact brought in Robotic pool cleaner (Non-Maytronic product) and demonstrated. During the demonstration (~2 hours) at least three times the robot toppled over and stopped working. Later we had a demonstration of M400 by a rep from Maytronics Australia agent. M400 was far superior to Non-Maytronic robot. We’re very happy with our decision. It is a great small tool which makes our life much comfortable.
