Set and forget
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.
Purchased in September 2016.
Does a very good job. Way better than manually scrubbing and vacuuming
Owned it for a month.
Pool size is 45,000 Litres
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.
Climbs up walls easily even with pool cover on....

Excellent Pool Cleaner
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.

Great Cleaner but needs a few improvements
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...nsuming to clean) but has large catchment for leaves and nuts. The unit is light to carry (much lighter than most of the good cleaners) and even when in water just hold it against the side of the pool and let the water run out before lifting out. it takes about two minutes to put in and about 5 min to take out, clean put on the caddy and put away its it really that quick and easy. The app is crap, who wants to manually drive it anyway, bought this to clean the pool, not me to drive it clean, but controlling it is average at best - do not buy it for this option. There are two design faults i believe. first is getting at the impeller is difficult, and if you have anyone in your pool with long hair (hair sheds) it gets wrapped around the pump impeller and reduces the water flow and ability to clean. this would be a problem with all cleaners but the S300i makes it difficult to fix, first you need to remove a cover with two screws, but maytronics took a shortcut where the cable is anchored to the unit, its part of this cover and is fiddly to remove and reattach this cover, two further fittings are easy to remove and then get at the impeller, other models i have seen have one screw holding a cover and you are done. Maytronics could and should fix this with little change to the design. The second problem is the rubber flap at the front to let the water out when finished seems to get stiffer as the unit gets older and i think it no longer seals properly and some water is sucked in there instead of through the filter cartridge. this causes two problems, reduced suction (cleaning) through the filter cartridge and distributes the dirt past the filter and around the pool to resettle on the bottom. i have glued the middle of the flap shut and fixed the problem but it should be part of the design. The unit stopped working recently one year out of warranty, I disassembled the drive and pump unit and found a small amount of water and a lot of condensation, the desiccant bag was soaked. So I cleaned and dried everything, used contact cleaner on the circuit board and dried the desiccant bag in the oven, (at a low temp) unit is now working again. it would seem that after two years (the warranty) the desiccant bag is no longer able to absorb the moisture and it starts to build up in the housing. not sure what the answer to this is and suspect all cleaners would suffer this, maybe it could be a service recommendation, in future i will disassemble after warranty for any unit i own. Im sure the moisture in the motor housing will have reduced the life on the unit. If you attempt this ensure all seals and surfaces are carefully cleaned and make sure you do not stretch the O-rings. use plenty of silicone pool grease/lube when reassembling. Apparently there are shops out there that can replace individual components on these which could also be an option if they fail. After all that i would still recommend this unit as it does what it want it to and for the reasons I chose this cleaner over many others - filters fine dirt and silt, fast and easy to clean, light and compact.

Questions & Answers
I had my S300i for 6mths and at first it worked well however lately it doesn't seem to pick up leaves and it seems I'm forever clearer the impeller. Can anyone tell me if the black sock wears out and if it needs replacing for it the machine to clean properly?
Don’t hesitate to contact Maytronics directly they are so helpful and very attentive just in case there is an underling issue, I’m sure they will resolve your problem .. also try putting the setting on ultra clean every 2nd or 3rd day
Hello Elroy. Thank you for reaching out. If the non-return flap (the black "sock" at the bottom of the filter basket) has torn or no longer sits correctly, it may require replacement. However, if the Dolphin is experiencing difficulty collecting leaves, soak the filters in warm water and a mild dishwashing detergent to shift any ingrained debris that may be contributing to the problem. Please feel free to contact our Customer Care Team on 1300 693 657 option 2 for any further assistance.
Hi everyone, I've recently purchased a S200 and I was impressed with the machine (cleaner), but decided I need the flexibility to program start and cycles times, so I upgraded to S300i. My opinion about the machine hasn't changed, but I'm incredibly frustrated with the robot (control unit). The S200 had a control panel with function keys for the weekly start cycles that didn't work and now that I've upgraded to the S300i, the control panel don't have the function keys and rely completely on the bluetooth and wifi connectivity that also doesn't work. I've upgraded and payed more money for functions I'm not getting. What am I missing here, the blue wifi indicator is showing it is connected but the app is stuck on "receiving info from robot". Has anyone else had this issue. One extremely frustrated and unhappy customer.
Hi Elroy. When using wifi as the preferred method for connectivity for the My Dolphin Plus smartphone application, ensure that both wi-fi and Bluetooth are enabled and that Location Services are also enabled as this allows the My Dolphin Plus smartphone application the access to the device to allow connection. These options should also be prompted when using the application.
A strong wi-fi presence be present in the area of the power supply is recommended as this allows the connection to take place. Should the signal strength be less than required, a wi-fi extender may be able to provide the solution to assist in boosting the connection and allow the connection and if using an extender, ensure to connect into this network. If the smartphone application gets to the final stage and is then unable to connect, this is generally due to signal strength. Please also note that the wi-fis frequency is required to be set to 2.4Ghz as this is what is supported by the robot’s power supply.
Please do not hesitate to contact our Customer Care Team on firstname.lastname@example.org or 1300 693 657 option 2 for any further assistance.
