I just went through the same thing your going through, and after reading some of the problems that people on here and epinions.com had with their Aquabug I went with the RoboKleen by Dolphin, and I couldn't be happier. I really like that I don't have to mess with those large hoses and getting all the air out of them and running all the junk through my pump and filter. The Robokleen couldn't be easier to use just toss it in and turn it on. It's enternal filter bag is easy to clean, and because I don't have to run the pump with it I will save the $220 I paid for it in a couple of years.
