Dolphin S300

Not very happy with this machine. I’m on my second controller and third motor. The original motor seemed to be the quickest till it died. This latest motor is painfully slow going forward and fast in reverse. It takes about 3 hours to clean our 18′ x36′ rectangular pool and there will still be stuff on the bottom.
The clean out is nice and so far cord tangling has not been a problem.
The worst part has been dealing with service and getting through to the right people… very confusing.
Interesting enough everytime we get a new motor all the cleaning functions work (extended clean cycles etc…) and then after the first use it goes back to the 1 hour or 2 hour limit. If the unit actually cleaned the pool in 1 hour this would be fine but when you have to restart it every hour for 3 hours to get the pool relatively clean it’s a pain. It would be nice if the same software was standard on all the machines.
Not that the warranty is almost over I am not looking forward to the future of this unit.

Dolphin S300 robot is back at pool store for the second time in 6 months. Repairs are covered by warranty thankfully. Pool store (Tucson Pool and Spa) very kind to provide a loaner unit while waiting for parts, again, from Atlanta. Tucson Pool and Spa is the best pool company in Arizona. Hope to get my unit back this week.

I love my Dolphin 300.
I tried other pool robot cleaners but they were too heavy when lifting out of the pool.
The 300 is also easy to clean the filters.
Only negative is that the cleaner is a bit too pricey

We purchased the S300 to replace a suction cleaner that slowed down as the filter filled up. In order to keep the suction cleaner running we had to throttle down the skimmer and turn off the bottom drain even when the filter was clean. The S300 is completely independent of the filter and circulation system so can clean even if the pool pump is off or the filter is dirty. A great benefit, too, is we can run the skimmer at full throttle which helps keep the surface a lot cleaner. So, summarizing my thoughts:
Pros: The S300 runs independently of the pump and filter system. It can be set to run for 2 hours and cleans the sides; or 1 hour to just vacuum the bottom. It can be set to run every day for a 5 day period after which it has to be reset (urges you to clean the unit). Very easy to clean with a removable basket that is easy to hose off, unlike many robots that have pleated filters. The basket gives two choices, very fine mesh screens or a filter material. I use the screens. The bluetooth feature lets me clean areas it misses if I have the patience to run it. I often just run another cycle.
Cons: The unit does not have a memory so isn’t able determine if it covers the entire bottom. It often leaves patches of debry untouched, especially along the base of the walls. (The suction cleaner ran all the time so it kept the bottom cleaner, but it also left patches untouched). To be fair, we only use the 1 hour cycle because the coaming of our pool is concrete. When we run the two hour cycle it rises up the wall and the rubber brushes churn against the concrete coaming so we fear it will eventually tear the brushes up. The power supply has to be near an outlet so the cable connecting the power supply to the unit lays on the pool deck. As it cleans the rubber brushes tend to stir up the lighter particles so they don’t all get sucked into the machine. The blue tooth option is rather rudimentary. It gives good fore and aft control but there is no real steering function. To turn it you have to patiently wait for the water jets in the unit to tilt the unit and push it sideways to pivot it and hope it lands in the direction you want.
Summary: Not a perfect machine but it serves our purpose better than the suction cleaners. Have not regretted purchasing this unit and have yet to talk to someone who has one that performs better.

This robot does a great job of keeping our pool bottom and water line clean. Easy to clean the filters. My 2 issues:
1. The cleaning cycle only lasts about 3 hours, so I have to remember to go back out and start it again to finish cleaning the pool.
2. The cord is horrible. It does not have a swivel where it connects to the robot so it is constantly tangling/knotting up and when you try to wind it to hang on the stand you have to constantly flip/turn the cording.

This is the best pool cleaner ever. I like the idea of how it operates. It is heavy. But that’s what the grandkids are for- lifting. I turn it on through the IPad app. Then at the end of the day, it gets pulled out and I rinse the filter. It doesn’t get much easier than that.
