I have the option of either for my pool - same cost. As of now, I've chosen the Polaris because I've heard good things from a couple of co-workers. The pool company would be more than happy for me to get the Kreepy Krauly, as they use mostly Pentair equipment.

Another of my co-workers has the Kreepy Krauly and has been very happy with it and says it only has one moving part, which is appealing. Also, becuase the rest of my equipment is Pentair, I would get a 3 year warranty versus just a 1 year with the Polaris.

I'd especially like opinions from anyone who has used, or has experience with both types - which would you recommend?

TIA
