Man. Makes me really wonder what the deal is with ME? Or better; with my Polaris. So NO ONE ELSE sits there at the side of their pool and watches it endlessly. Watches it go back over the same spots over and over. ...Then tweak the directional nozzle on the back and watch it some more.

I have put on new wheels. Polaris sent me a new timer valves that backs it up twice as often, which has helped some, but it also has increased the time it takes to clean because it is spending so much time backing up and away instead of cleaning.

It DOES eventually clean the pool. It does miss large areas on the incline between the deep and shallow ends. I use a brush and redistribute the dirt and keep it going. I DO use the sand/silt bag because it works better for me. I just can't imagine buying one of these knowing what I know over something like a Dolphin. But I guess I'm really in the minority. And it makes me wonder if my cleaner is a lemon.
