No information about handle positions
Overall love the M400, does a great job. I’m not sure what position I need to have the handle to do the walls. I have a 60000 litre fibreglass poll

A good pool cleaner for custom pebblecrete pool.
I've had the M400 for over 1 year & it has performed adequately for our custom kidney shaped pebblecrete pool. The M400 can usually clean the pool within 1 session, unless we've had a storm and there is more debris present requiring an additional cleaning session.
The unit is easy to clean & the filters can easily be removed for cleaning.
The only complaint is the fine filter panels are easily broken, particularly the lower lugs that connect into the frames when too much debris is captured. They seem inadequate for the pressure of material a...

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.

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!!!

Doesn't climb that well
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.

Questions & Answers
Hi i have a new m400 wb, thru the app can you tell robot to concentrate on the walls cheers steve
Hello Steve. Thank you for reaching out.
Within the My Dolphin Plus application there are are options to set the Dolphin to Regular Mode, Floor Only and Ultra Clean cleaning modes. These modes do not have the option to solely focus on the walls however, if the walls are manually brushed down, the Dolphin should collect anything on the pool floor.
My new M400 climbs walls fine but doesn’t run along the waterline, it just stays where it surfaces, cleans that bit before then reversing back down the wall to the pool floor ! I’ve tried adjusting / locking the handle so it stays at right angle to Dolphin but it doesn’t seem to actually lock in place. Thanks in advance for any help :-)
Hello David. Thank you for reaching out. If the handle is in the main position, the Dolphin will clean that straight up and down area of the wall and waterline. However, if the handle is adjusted to be on either angle, the Dolphin will them assume that angle when it reaches the waterline. If the handle does not appear to lock into place, Maytronics recommends to ask the store of purchase for assistance in securing the desired angle. Please do not hesitate to contact our Customer Care Team on 1300 693 657 option 2 for any further assistance.
Can anyone tell me what the different positions of the handle?
What position does the handle have to be to up the walls?
Thanks any help would be appreciated
Carolyn. if you offset the floats (handle) so they are at an angle (left slant or right slant), the unit will go sideways on the surface against the tiles. if they are aligned the unit just stays vertical.
Hi Carolyn, Shane is correct. When changing the direction of the handle, the robot will take this direction, especially when cleaning at waterline level.
Hi, thanks for that
Do you know if there is any written documentation that shows the different positions of the handle and what it achieves?
