I have the sigma (previously owned s300i) cleans great better than my old one. Was getting stuck on drains I called factory. I had to ship it to them (they paid for the return) the added a middle brush fixed the problem Shipping wasnt cheap but it was worth it

We have been unground pool owners for years so when I found this pool cleaner I was hopeful. This is the BEST pool cleaner we have ever had. So easy to use. There pool is so clean! You don't need to attach to the pool filter in any way. We just drop it in the pool and push start. I would highly recommend this cleaner. It's worth every penny

Bought this last season, and am extremely impressed. Came from a Tigershark, which did an OK job, but would get stuck too often in my pool. The Sigma has yet to get stuck once all last season and after about 10 uses this season. Powerful pumps, ripples the top of the water from 10 feet deep. Quick cleaning. Bluetooth is hard to use for spot cleaning, I just don't bother with it. It cleans my 20x40 foot pool in about 2.5 hours, no need to spot clean after. If it lasts another 2 seasons, I will consider it one of my best purchases for pool cleaning. Have not felt the need to manually vaccuum since I bought it. Highly recommend.
