I need a bit of an education here.
Every year at one point or another, my liner lifts about an inch off the floor in about a 6' x 2' area in the deep end. I've resigned myself to believe this is due to ground water. I've learned to live with it, but the most frustrating thing is that our Hayward Ultra Pool Cleaner gets hung up as the suction pulls the liner up to block the inlet of the cleaner.
I'm guessing I will have this problem with all suction cleaners.
I'm not sure if either a pressure cleaner or Robot would be any different. (Don't they all essentially suck dirt off the liner)
Any recommendations on a cleaner that would still work when liner is raised about an inch from the floor?
