Hi All! We are entering season 3 with our fiberglass pool. We have manually brushed and vacuumed the first two seasons, but I am seriously considering a robot for the upcoming pool season. My concern is whether it will really be worth it in our situation. We have a fairly large pool in the fiberglass world - 16x37 freeform shape, with 8 bucket seats (plus the safety ledge). Key West by Tallman I am guessing the bucket seats are a lost cause and will just need to be brushed first, but can a robot get the safety ledge relatively clean or will it make the robot fall down? Our pool builder sells the M4 and that is what they suggest....but the price is awfully steep. I've heard good things about the Polaris 9550. Any recommendations? Should I just keep going with the manual vacuum/brush? Any suggestions are welcome!
