We use the Polaris 65 now. It's ok, snags the dog hair and leaves but it does nothing for the 'fine' stuff other than blowing it around some. Plus, it has the occasional nervous breakdown and forgets what it's doing. Then, it swims in circles, going over the same area time and time again until I haul it out, drain it, talk to it in a calm and soothing voice . . . Are there any gadgets for an above-ground pool which actually work without supervision?
