We have had the dolfin s300i since sept16 (4+ yrs) it was supplied with the pool contract. it was repaired once under warranty and had run without issue until recently. Unable to Find any repair info online I persisted and found that the ‘cable anti twist coupling’ in the power cord was faulty. I was able to pull it apart , repair pins,relube oring and re assemble . It was just not making good connection inside. Has been fine since and is a good alround cleaner doing sides and collecting most leaves. We have lots of small leaf trees. I have only had the pool too far gone in hot weather twice where I had to brush clean the pool.

This cleaner needs more attension than my $100 aldi cleaner. Maybe my pool is to big 9x4.5. No satifaction guaranteed warrenty. That shouls spook you from the start. Can see it been great in a small pool with no trees within few hundred meters.I have to clean it every 2nd day. The filters in it will probably not last a season. Does not get to the step. Cleans ok but needs lots of cleaning. If we go away for a week what would happen.

FACTS
Owned it for a month.
Paid ~$2,400
Pool size is 45,000 Litres

POSITIVES
Does a very good job scrubbing and cleaning tiles.
Hook it up to to home wifi and and download the app and you have complete control of the robot.
Quiet
Climbs up walls easily even with pool cover on....

I purchased my robot 1mth ago, its the best purchase I have made for a long time. We have had our pool of 7ys i wish I had bought one when we got the pool. So easy to use, great that it cleans the walls too. Makes our busy life a lot easier with one less thing to clean.

Robot has been in for repaired twice in 4 years. Told it requires new motor and CPU for $650. Would have been better off purchasing a cheaper brand and replacing it each year. With such a huge outlay one would expect the motor to last longer. This should be covered under Australian consumer law.

I have owned my Dolphin 300 series for 3 years and have had no satisfaction with it at all. Apart from having to have a new power cord fitted ($350 as it was out of warranty), the machine does a poor job of cleaning the pool. It really struggles with leaves, just "pushing" them around, and I always end up having to manually vac the pool, which defeats the purpose of buying a Dolphin in the first place. As for the app interface - a disaster. I just keep getting the "oops, something went wrong" message when I try to access any of the programs ot...

I had JB Pool construction build my in ground pool and spa. The Maytronics range Jamie believed was at the forefront of the Robotic pool cleaner market and rightly so.

I chose the s300i over the m400 for 2 main reasons,
1. App wifi connectivity
2. Design of the large filter/Catchment basket

I have a large amount of leaves and dust on my acreage property and the 300i takes care of it with ease!

Great choice all round!

I love this 'set and forget' pool cleaner. living in extremely red dust environment is made bearable with the dolphin s300i. makes picking up dirt and debris easy! THANK YOU

This unit gets stuck on main drain even when pump is off also I have brick pavers around my pool. Can not help little pebbles from getting into pool. This machine will never pick it up yet previously my tiger shark did great, sorry I did not buy another tiger shark.

Had it a month and pretty disappointed with it.
It is pretty random how it goes around the pool. There are times when it just goes backwood and then forward, in half a meter.
The impeller isn't strong enough to keep it pressed on the waterline tiles.

The cost is excessive when compared to the results.

I trialled a Dolphin s300i on Wednesday and by Thursday I had ordered one. What a great investment. The pool cleaner I had was still working but only cleaned the floor. After the bushfires the pool was blanketed with ash and dust. I thought I would never get rid of it. The dolphin rid of it within a few days. The best thing is it scrubs the waterline and walls so no more lugging of the broom. Our pool has never looked so clean. We have a pine tree close that drops tiny pine needles that sink down and land in the grout lines, I couldn’t believe...

Recently purchased the Dolphin S300i. Great product. Pool looks amazing. Got ride of the dust and leaf matter with ease. Simple to use and to clean. Manual drive mode on phone allows you to target problem areas.

We have a large pool and neighboring trees drop leaves & twigs into the pool. This unit although expensive cleans all this debris without any trouble.
After an initial issue which was sorted by Maytronics and the agent extremely promptly this unit has not missed a beat. The unit climbs the walls of the pool then moves sideways cleaning along the waterline as well as the floor and within a couple of hours of setting the unit up the pool is spotless

Have owned the pool cleaner for 7 months now and hasn't missed a beat, pool is surrounded by trees so lots of leaf litter and dust, so far so good, easy to use compared to setting up a suction cleaner, just hoping for the high cost of the unit it goes forever.

We live in a very heavily treed area so our pool is constantly filled with debris from leaves to small sticks, the Dolphin 300i cleans it all up with ease, it very easy to empty and clean the filters, we set and forget.

Bought S300i 4 months ago and pleased with it so far. It's expensive but I've had 3 other cleaners before this one (in 15 years) and this is the best so far. The best thing is that it's not connected to the pool pump so the pump can run without the extra load of a cleaner. We have a large pool that collects a lot of leaves so I have to empty the basket 4-5 times a day until it's cleared out - but that's ok as I had to do that with the pool filter basket anyway. Does not clean the steps - tries to but doesn't succeed so I usually vacuum them manually. You can do it with the app but it's a bit of a hassle and the last couple of times I tried to use the app it didn't work- not a major problem to me though. So far so good.

Love this pool cleaner. Thought our pool was clean with our old cleaner but couldn't believe the difference when we got the maytronics cleaner. It is now crystal clear all the time. never have anything in the pool it picks up everything.

My Dolphin has taken over all the work I used to have to do myself or pay a pool guy to clean the leaves and debris from overhanging trees.

It is just set and forget and clean the basket every so often

I have had this S300i for just on three years now. cleans the pool well, the two modes Fast (one hour) cleans the floor only and long (three hours) floor and walls is a great option and works well. Does not clean the steps but dont think any cleaner does despite what the rep says. This unit is super easy and fast to clean, the filter box lifts out with its own handle is fast and easy to hose out, could not be easier, looked at many and this was one of the few that would filter fine dust without needing a bag (that looks way too hard and time co...

Made some pretty good decisions on pool equipment before but this is not one of them. Have had the unit for 2 years and 3 months and in that time the controller has had to be replaced on site by a rep, have had problems with the app which were resolved and the power cable had to be replaced under warranty because it was faulty. Now I have had to pay 325 dollars to have an impeller fixed for a unit that was cleaned weekly and it was cited as maintenance. I would say more likely poor design. When it cleans it cleans well but it comes at a cost. Poor product and clearly badly designed
