Easy to remove and clean filters
Thoroughly cleans pool
Has handy storage caddy
Less effective on curved surfaces
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.
DO NOT BUY FOR ABOVE GROUND POOLS
Was a gift, cleans ok, spends too much time up walls, has now punctured liner. Power supply failed, and had to be replaced. Does not like curved surfaces, stairs, etc. The edges (front and rear) are too sharp for tight spaces.
Purchased in October 2017 for $2,000.00.
Factually piece of crap!
This is a grossly over rated and over priced product. Does not come close to living up to its claims. Shame on me for purchasing it based on over inflated advertisement. Anything else I have to say would be offensive. I only hope no else get suckered on this product or its claims,
Just doesn’t work on kidney shaped pool... It may work on a rectangular or square pool but the curved sides on a kidney shaped pool knock the machine out of any pattern to cover the pool. The machine I trialled spent 95% of its time down the deep end of the pool. After a couple of hours I dragged it down to the shallow end but it soon crept down to the other end. Shame, I would love to have a robot cleaner that worked!
Very expensive product. Bought it in late May. Stopped working in early July after just a few weeks. We sent it in for "repair" and they held on to it for 2 weeks, replaced some part (drive motor, I think), and then called and said it was fixed. When I brought it home it still was not working at all!!!
Turns itself off.....
We purchased the Dolphin Supreme M4 just on three years ago, as soon as we got it the machine started turning itself off 10 seconds after it has been turned on...so we always need to restart it.We purchased it from Byron Bay and as we live in Ocean Shores the Dolphin has to be sent to the Gold Coast for any warranty work.Because of this we decided to wait until we got a service under warranty and get it all done at once.I had lost track of time and just realised that the warranty ran out just 3 months ago so I contacted Maytronics on 0732729...633 today to ask if they would still honour the warranty on the machine and I was told "bad luck".I am very disappointed with the after sale service and feel that a company of this size should have better customer relations!!!
Worked for 1.5 seasons and now won't turn on anymore.
Worked for 1.5 seasons and will no longer turn on. What a waste of money. Tried everything. For this kind of money it should be better quality then this. Now I have to attempt their warranty process and see if they will live up to their warranty promises. Sad that this happens.
Makes me angry
I have a pool 10 mts x 5 mts. The M4 always forgets the corners, doesn't clean the bords. In the deeper part of the pool, the robots stays working from right to left, cleaning always the same stroke. Whatever combination of the floaters I use, it always come back at the same spot.
The only splutions is to clean myself the old fashioned way. This is my second robot. The first, the Dolphin with the flashy colors worked better. Answers to Maytronics were not answered. Of course. What do they care. I am looking for another brand now, hoping for better service.
Complete Piece of Junk
had this robot for 2 years and it only worked for less than 6 months of it. I had it continually back at the pool shop getting fixed. This time it has a buggered PU Board and a shot motor and will cost more to fix than a new one would. Pool shop bloke says that he has has endless issues with dolphins and will never sell them again.
It never worked. the concept is great, the machine is garbage.
Questions & Answers
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?
I have an m400 and it was working fine. Took it out of pool to clean and put it back in. Now it doesn't turn on. Light is on the power supply but nothing happens.
Hi Shaggy38. Thank you for reaching out.
If you Dolphin M400 is not working correctly, it is recommended to check its impeller and drive system for any obstruction/s that may be contributing to its performance. If these areas are clear, assessment is then recommended to determine the issue.
