Does anyone use an automatic cleaner from Aquabot Pool Rover or Pool Rover Jr for their Above Ground Pool??

Just curious because we are considering purchasing one this year. Last year we tried the Roboclean and it worked great for about two weeks and then it quit working. Got another one from the dealer and it quit within a week so we just gave up and waited until this year.

They aren't cheap but I would not mind paying for it to keep me from vacumming so much plus not having to replace the water that I would loose.
