I have a 18' x 48" Easy set pool and have never been able to install it over the years without a myriad of folds and wrinkles on the bottom. Therefore I have never considered getting a vacuum system that travels along the bottom on its own. I have the larger sand filter(2500 gph?).
Is there a model that will step over the wrinkles on the bottom? It's almost time to take it down this year, but I just broke the top of the vaccum body that fits into the skimmer, so maybe it's a good time to look into it. Intex does not have any replacements in stock.
