Just thought I'd give you guys a laugh. I had a 16x32 vinyl pool put in over the fall and immediately covered with a mesh safety cover.
We set the timer so the pump ran for 4 hours a day and the polaris 280 ran for 2 hours a day. Last week, we removed the cover. The polaris would not clean the entire pool and would not climb the incline from deep to shallow or the walls. I read the manual, pointed the rear jet in every direction, checked the hose for leaks...etc. I showed a friend a pic from work of how clear my pool was and pointed out the drain in the bottom of the deep end. It took a couple of days later to figure out, but er-uh, I dont have a drain in the bottom on the deep end. That is a Polaris Drive Wheel!
