Dolphin S300

This is my second year with this cleaner. After struggling with Polaris for many years I am so pleased with the Dolphin. Easy to clean. Cleans well. Only became entangled with cord once. The cord does twist on itself but I simply untwist it every time I empty it. Highly recommend it over the Polaris. Seemed I was always working on the Polaris.

Pool robot cleans the pool pretty well, although definitely only gets the waterline in a few spots. The cord failed for me after 6 months but they replaced it under warranty. The remote control app doesn’t work at all and is completely useless. But overall is really does clean the pool well and is very easy to empty so I am satisfied.

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.

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.

Expensive, but worth the investment to minimize your cleaning time and maximize your pool time. We have a Barrier Reef Fiberglas in-ground pool. The pool has plenty of curves and free-form steps. This cleaner cleans everything. I typically operate it on the 2 hour cleaning cycle and that is all it takes. I use the app to setup the cleaning cycle schedule so it cleans while we sleep. Like mentioned in other reviews it cleans up the worst of Fall leaves, but count on cleaning out the filter basket frequently, which couldn’t be easier. The cable does get twists in it at times but that is easy to remedy by disconnecting the cable from the controller and untwisting it and reconnecting it. I highly recommend this pool cleaner!

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.
