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.
Had an old Polaris pressure cleaner which gave up the ghost just before Christmas and decided to replace it with a robotic cleaner. We have a rectangular pebblecrete pool and after the recent storms in Sydney I put this cleaner in the pool for 4 days in a row. The amount of fine dust this has managed to remove from the pool is incredible. Very happy with the performance. The only downside I can find is the weight of the cleaner when you remove it from the water. I guess that's a small price to pay for its ability to scrub surfaces as well as vacuum debris.
we have just been told that it will cost more than a new one to repair . it run out of warranty 2 months ago . i expect that its life would be longer than that . out last one lasted 12 years with annual services different brand . It has been a good cleaner . but dies just after warranty grrr .NOW WHAT TO REPLACE IT WITH
I replaced a Dolphin M4 which I had for 5 years, with a newer M400. I am using it for the first time today. I can see a big improvement already. I am so happy about the change and would recommend this model. It's so easy to use. Easy to maintain and clean.
It get stuck easily on the steps of the aquatechnics fibre glass pool
Got this robot cleaner for cleaning the rectangle shape fibre glass pool for dirt and leaves plus brush the surface of the pool. It get stuck at the corner of the steps very easily which I have to constantly check on it to make sure it is doing its job. I wish I can just switch it on and leave it. Not sure if it is because it is with form rollers in stead of the silicone flips rollers.
Cleaning the pool very very well but damn it's heavy
We have only had this cleaner for about 3 months and it's our first robotic. (Tiled pool) The bad, it's very heavy, pulling it out of the pool full of water it must be about 15 to 20 kg. The unit weighs 10 kg. My wife couldn't do it plus you are bent over lifting it up. Good; so far doing a fantastic job of cleaning my pool. I get a few leaves but more fine dirt dust and it's excellent. I like that you get two types of filters, one for heavy and one for finer dirt. Very easy to clean the filters and having the filters easily accessible from the top of the unit is a great design. My pool has never looked so clean. Old cleaner was a Hayward pool vac which was running all the time with the pumps being a vacuum unit. I use this about once a week and I'm amazed how much fine dirt and debris it picks up. It really does climb the walls very well, pool coverage very good, misses the corners but I don't see that as an issue, to be expected and I just quickly brush corners then put the cleaner in. No kinks or tangles the swivel cable function works well. The stand is good quality and well designed. I'll update this in 12 months but so far all good, I do love it but seriously needs to be lighter. I bought the cover for the unit and the stand, don't waste your money, buy a good BBQ cover far cheaper and far better quality. I would give it 5 stars for its cleaning but only giving it 4 as it is just so damn heavy.
Really great robot
Water is crystal clear and catches everything. It can’t climb my steps unless I reduce the angle on the floaters, that seems to help it climb them easier?? Does everything and is fun to watch. I now want to sbuy the cover to keep it dust free on my patio. Excellent scrubbing.
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,
Owned nine months and really happy!
My experience with this pool cleaner has been different to a number of the other reviewers, maybe the majority of those who write reviews are the unhappy ones? But I have been delighted with our M400 after 9 months of fortnightly use in a smallish concrete rectangular pool. For starters the company staff really tried very hard to help me select the right unit. Secondly the unit does all it is claimed to do — climbs the walls, moves slightly horizontally when it reaches the surface, and covers the pool comprehensively in the 2.5 hour cycle. Negatives? The cable is a little inflexible to rewind, the unit is fairly heavy when lifting out of the water, and the carrying caddy is not a perfect design. I clean the filter cartridges on the unit after each use, which maybe some people do not, and that is a quick exercise. I was originally also critical of the company for the confusing marketing approach they were using in applying different badges to what was essentially the same machine for different distributors. But the M400 I have has done all I expected and more.
Do not buy if your pool is curved in shape or has curved sides!
What a mistake for the price! My old Creepy-Crawler got around to every corner of my pool, but unfortunately for me this M400 Dolphin gets stuck as soon as it hit the curves. Wheels are spinning and nothing moving!! I took it back to the retailer and complained it was getting stuck. I commented it had the wrong brushes - (they were the foam Wonder brushes(?), instead of the PVC brushes). They said no, I had the right brushes for a fiberglass pool but I had the wrong angle on the handle float. Hogwash - I adjusted it and made no difference. Now, every time I use this M400 I have to keep an eye out so when it gets stuck I have to move it to get it going again. Admittedly, the areas it does clean, it does a good job, but I always use the Ultra-fine filter cartridges instead of the net filters. I just wished it would clean the whole pool and without my intervention to get it going. The advertising for the Dolphin is that you sit back, relax and never have to worry about the pool cleaner. Yeah right!!
I am really sorry that this product is over-priced, over-hyped and over-here...in my pool.
Had the same problem threw a golf ball in which sat in the deep end and solved that problem. It ran over the golf ball and sent in on a new direction now cleans both ends of the pool. I have had the same machine for 12 years and it has had an active 12 years in the pool. Replaced motor drive after 6 years
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!
Don't waste your money
Lasted less than a year and won't even attempt to turn on. Wasn't cleaning the entire pool when it was working, always missed the same part of the pool no matter what setting I used. Really disappointed that it won't even turn on anymore. I was told that this pool cleaner was the best one on the market but I could have bought two of my last pool sweeps and it lasted a whole lot longer than a year.
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!!!
Maytronics Supreme M4
Worked well for about a month. Then left small dirt on bottom. We bought it last summer and this summer didn't clean that well and the end of June it completely quit working. Won't turn on or anything. Messaged customer service and we still have heard nothing from them. Do not think it was worth the money considering it only worked for 1 summer. Also very disappointed we heard nothing back from customer service.
Dead after less than a year
Blue power lights come on for 2 seconds then goes off. Checked all outlets and ground fault. Cleaned filters still doesn't work--not happy! Checked all troubleshooting info i could find, nothing works. Hope this is not a bad sign of things to come. Would expect more than one year of service!
Just started with our third season with the M4; first year it would not climb the pool walls effectively and would not break the surface of the water to clean the water line. Sent it back under warranty and didn't receive it back until the end of the pool season. The M4 cleans about 70 percent of the pool and no matter what settings are selected it seems to clean the same spots repeatedly and missed large sections. It doesn't clean the corners but wasn't expecting it to as it's a residential model and not a commercial version. The robot that my pool supply store loans out is 10 years old and has been abused and is twice the cleaner as the M4, it's also a Dolphin so I thought I made a good purchase. Disappointed with my purchase, wish I had went with either a commercial model or different manufacturer all together. Maytronics only allows the local pool supply store to service the commercial models and not the residential ones which is very disappointing.
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 0732729633 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!!!
After purchasing this, I couldn't ever own a pool without having one of these. Makes my life so much easier, now I can get on to the other outside jobs whilst this cleans the pool for me. Cleaning the robot takes 2 mins before I put it away in the garage.
Expensive at 3k but honestly for the fact it makes my life easier, it's worth it.
Only negative I have is that since I've purchaed it over a year and a half ago, absolutely no communication from the Maytronics company, no emails no phone calls no post asking if I'm happy. Other brand names like Miele for my white goods are in constant contact.
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.
