Hi all, we have an in wall pool cleaning system, but it doesn't work (!), so we're going to break down and buy a robot. I've been looking into the Aquabot Classic, which appears to be good value. We have a relatively small (10,000 gallon) fiberglass pool (San Juan Rio), no ladder, but there is a swim out and a few stairs, and a main drain which the dirt seems to collect between that and the nearby wall. We'd like a unit that climbs the walls and cleans the water/scum line as well, but not break the bank! Thoughts on this unit? thanks!
