Comments about Heritage Pools Zappy Auto Pool Cleaner:
I purchased the Zappy thinking it would help clean the grime off the bottom being it would suction through the pump / filter, but it would get started, hit a small snag in the vinyl...eg; seams...and it would stop. It was designed more for a solid concrete bottom pool then i think it would work wonderful. I have a 1,000 gph pump and it wasn't strong enough even though it says 700 gph is sufficient.
Bottom Line No, I would not recommend this to a friend
