We currently have the Polaris 380, I believe. We are looking for a high quality, robotic vac that does a much better job of scrubbing and cleaning the surfaces of the pool. I've seen a number of recommendations on various review sites, but I thought I'd stop by here for quick advice.
Since we plan to have this for quite some time, I would like a high quality, durable cleaner, even if it means paying a premium. Also, note that my current vac has a pump of its own, and my equipment (pumps) are Polaris (main pump is variable speed) with a Jandy filter (not sand). The pool is about 17k gallons, with pebbletec surface.
