5 years after my last post about my circa 2011 Polaris 280, it's finally going belly up on us. We've replaced parts as they fail but at this point we can't figure out the problem. The cleaner floats around the pool barely touching the bottom, at only 24 rpm. Takes about 8-10 hours to completely clean the pool if we're lucky. Maybe it's time for an upgrade? I keep hearing about the electric robots but wonder how well they can pick up pine needles and worms, and the occasional slug. The Polaris was able to pick up that stuff easily but I found it to be a hassle to use: difficult to attach and detach at pool wall; gets stuck in corners and on the stairs; sprays water all over my windows. So... recommendations please!
