Excellent product M400
Purchased about 4 years ago and has never let us down. We had a an issue with our Dolphin initially cleaning the entire pool always cleaning the deep end. By adjusting the handle angle until we found the right location to suit our pool and it cleans the entire pool including walls every time.
Noticed a big saving in water not having to backwash as much compared to our previous cleaner that worked on the suction from the skimmer box.
Good quality machine and great design. Filters simplistic but effective design are easily accessed and easy to clean. Caddy makes it easy to pack up and put away after each use.
We love it as it makes owning a pool so easy.

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

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.

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.

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 ...

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.

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.

Fantastic pool cleaner
This is my second robotic pool cleaner after using a number of suction hose type pool cleaners over the last 20 years of pool ownership. My very first robotic cleaner was superior to the suction hose cleaners that I’d previously used but it didn’t always clean up the fine silt that sometimes settled at the bottom of my pool. This previous model also had other shortcomings in that the cable badly twisted and the baskets were clunky to remove, clean and replace. Anyway after several years of loyal service it died. (I was kind of relieved). After ...lots of research and the offer of a free trial I settled on a Maytronics S200 pool cleaner and was immediately impressed from the get go. On its very first use it charged through the silt and other random leaf litter in my very large pool and sucked everything up. It did the same along the walls and after a couple of runs, lasting about 2-3 hours each cycle, it cleaned the entire pool surface including the ledges and steps. It is also very easy to clean the unit afterwards as the basket lifts out using its folding handle and the fine mesh holds all of the silt and micro debris as I walk to the tap to give it a rinse. In summary, I highly recommend this product. It wasn’t cheap and I was tempted at time of purchase to explore less expensive products but glad I resisted to avoid anything inferior to my S200. I can’t remember when I last used a pool scoop to clean my pool and my new S200 robotic cleaner has certainly made my pool maintenance a lot easier. (I do not have any association in any way with Maytronics or pool retail or associated industry. I offer my comments in good faith to assist anyone contemplating the purchase of a good robotic pool cleaner).

Awesome cleaner, great service from maytronics
contacted Maytronics for a demo of the m400 and i was contacted almost immediately by a local dealer who arranged to come around with the unit and give it a run in my pool. The agent from the pool shop was able to answer all my questions which ultimately lead to me purchasing the M400.
The M400 does an excellent job of cleaning fine debris from my pool, i don't really have a problem with leaves. Seeing as i've got a cartridge pool, having the M400 frees up my skimmer box to just filter the top of the water. I'm also able to save power by running my pool pump on the eco setting.
All in all, great purchase, should have picked one up ages ago.

Questions & Answers
My Dolphin M400 doesn't go up the Wall, I have the Handle diagonally positioned as per the Pool shop advice. I brought it back to the Pool shop and they tested it and they said it's working as long you have the Handle diagonally set. it went up the Wall only once in 2.5 Hr, that's all. My Pool is Pebblecrete.
Can you help Please.
Hello Alfie. Thank you for reaching out.
Wall climbing models of Dolphin, inclusive of the M400, are programmed to climb to the waterline every four minutes. if your Dolphin is experiencing difficulty climbing, the following is recommended:
- Thoroughly rinsed the filters under a tap or, soak in cartridge cleaner or a mild dishwashing detergent and warm water solution to assist in the removal of in-grained debris.
- If the unit is attempting to climb, brush down the walls and/or slope down manually to loosen any build up. The Dolphin should then be able to grip these surfaces and maintain them on its own going forward.
-Water chemistry levels and pH levels that are out of recommended range can prohibit the unit from climbing to the waterline. This is due to the surface becoming slippery and the robot is then unable to gain grip/traction. A full water test and the pool balanced is recommended. Following this, brush down of the surfaces to shift any slipperiness.

Hi recently purchased a M400, can someone confirm the M400 can be set to clean the floor or walls only
I’m using the my dolphin plus app and can’t see any options to switch programs to floor only
Hello Shane. Thank you for reaching out. To change the cleaning mode of your Dolphin, this is located within the My Dolphin Plus application under mode or cleaning mode.
Yes tried that the actual app doesn’t have options just 2.5 cleaning cycle
If you have a direct email I’ll send some screen shots but your app has been updated and since then we have no options to clean floor only
Hello Shane. Please send any screenshots and also the serial number of your Dolphin to our team at email@example.com
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.
