We've had a polaris 280 for years now and need a new cleaner. I see on polaris' website that there is the 280, 380, 480, and 3900 sport. I would love recommendations and advice. We do have the dedicated booster pump and cleaning line. Our old 280 has been rebuilt too many times and husband is ready for new cleaner. Our pool design does not and has never allowed the 280 to completely climb the walls or steps properly. i also have a bench on the deep end that it for sure has never climbed. we want something that will climb well.
thanks
