The performance has been excellent. The only problem we've had was with it getting stuck against my steps. I replaced the backup valve and it's never been stuck again. Had a poolfriend overhaul the innards about three years ago(I've since learned anyone can do it-kits are available online, eBay, etc.). I can't imagine another cleaner would be much better but some of the reviews in this forum make me wonder......LOL

Yeah, I've heard it both ways now. Some people love the KK and others love the Polaris. We decided to go ahead with the Polaris. I just like the idea of having a pressure side cleaner.
