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. Neg...atives? 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 tha...t 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 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!!!
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.
Had mine for over 2.5 years now. Use it 1 to 2 times a week. Have a 75,000 pebble crete surface (concrete pool). Never misses a beat. I always take my bot out - rinse it off and store it out of the sun. Keeps it looking and operating like new. Don't leave it in the pool and store out of the sun -that is the trick to it lasting many a year. Sure, it involves a bit of effort to put it in the pool, take it out the pool - rinse it off and clean the filters and store the bot - but - if you want top notch cleaning and a pool that is pipe free...for when you swim - then this is the machine. I researched very carefully - this is defiantly the best bot in my opinion. The top loaded filters make it so easy to take in and out. Every so now and then - I have to remove the screw on top of the bot to get to the top fan to remove some dirt or weed or whatever that has wrapped around the blade. Some simply care and maintenance is all that is required. I am no handyman - so very easy to use.
Bloody Bonza Mate
Originally had the M3, but found it got caught in the corners of my pool. Was given a full refund on my upgrade to the M4 and have never looked back. Excellent and recommended to anyone. Mine is a 10m x 4m concrete pool. Cudos to Aqua Service Nowra who sold me the original and upgraded Dolphin.
Awesome after sales service - up and running in no time with a replacement part
Is the m4 the best cleaner in the world - I dont know. But I do know it works better than my old creepy and by doing it by hand. I am impressed by the silting that it gets off the bottom of my pool floor. I didnt even know it was there. I did a lot of research and bought about 11 months ago. Then one day it stopped working. I though I had better get on to this as the warranty is probably over. I emailed Maytronics with a query of what to do. I was responded to quickly by Jon - to my surprise he was amazingly helpful. In no time he had...diagnosed the problem and dispatched the replacement part to my home. This morning I fitted it and it worked again. I was so delighted that I wanted to share. Is it the best cleaner? - I still dont know. Is the after sales support excellent - absolutely. Thanks Maytronics and Jon - what could have been a bitter experience is a customer converted for life!
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.
Id buy another, but I dont have to.....
After spending, literally months searching and researching, gaining info on robotic cleaners, Kreepy type and other cleaners I decided on a genuine Maytronics Dolphin M4.I work 14 hours a day 5 days a week so my time is the utmost. I have a 75,000litre concrete pool, and the machine does not stay in the water after a clean.I was told I can leave it in but, chlorine can damage.... I hose it off and use it every second day. After the demo, I did not seek the M5, as the more gizmos there are on a mechanical item, the more can go wrong. My M4 actua...lly does the walls, scrubs for about a metre then goes back down. For this to happen you need to adjust the floats. Not being a mechanical or technical brainiac, I needed a machine that was easy to use, clean and store with maximum warranty bought from a person who took time to explain things from a experienced point of view. I have had it now, about eight months with no hic ups. In the meantime I have purchased a new filter and eco pump from same outlet, also to a very high standard of service and friendliness. No Im not a relative or employee of either Maytronics or Paramount Pool shop at Ryde.
With the trolly it is easy to transport and store away. Doesn't jam up like previous filter driven cleaners.The best part is just to put it in the pool and turn it on and walk away unlike the filter suction cleaners where purging the suction line of air is necessary. Easy to clean and after 12 months constant use no problems mechanically.
Questions & Answers
i bought my m 400 just before christmas and noticed straight away that it wont climb the walls of our fiberglass pool at all ive played with the float arms in all different positions but to no avail .i also noticed the unit inside the box comes with foam rollers but the pic on the box shows the rubber type.i went back to the shop who told me there technicians are all on holidays but couldn't offer me any other advice ..i wanted the rollers changed to the rubber type as my old zodiac cx20 had the rubber rollers and climbed the walls fantastically..ive also played with ph levels to see if that makes any diff but to no avail..now i must admit it picks up all the fine dust better than any other cleaner ive used in the past but this is the only one that wont even attempt to climb the wall for $2000, bucks im really disappointed tbh
When I have the maytronic 400 cleaning the pool after a while it turns off is there a timer on it or does it switch itself back on later
Hi Dianne. The Dolphin M400 unfortunately does not have a timer feature of which allows it to turn off and on. When a robot switches off mid-cycle, we recommend to check for any obstruction/s within the impeller and the drive tracks. The impeller, which resembles a fan, may be tangled with leaves, hair, and other debris. With the robot disconnected from power, remove the impeller cover, which is located at the top of the unit where the blue cable is connected, and examine the unit. Any obstructions are to be removed. Debris may also be stuck in the tracks and/or rollers. Again, with the robot disconnected from power, turn it on its back and roll the brushes with your hands. You may feel resistance if there is something stuck. If you cannot roll the brushes to free the obstruction, the side plates are able to be removed from the unit to inspect the full tracks and rollers. Should this above not resolve the problem, assessment of the robot is recommended. Please do not hesitate to contact our Customer Care Team via email to email@example.com or on 1300 693 657 option 2 who will gather your location and postcode and will advise of the closest dealer that is able to further assist.
Yesterday the cleaner had to be turned off 30 minutes after it started cleaning and now it will only run for 30 minutes. All the settings are fine and doesn't need cleaning. Any ideas?
