I had a problem with the cleaner getting stuck behind my AG stairs. The stairs extended about 3 ½ feet into the pool and the cleaner was frequently getting stuck. To fix it, I bought some water tubes from Leslies and filled them with filter sand and placed them along the side of the stairs. Now the cleaner bumps up to the sandbags, turns around and continues merrily on its way. I think I may have seen this solution somewhere else on this board so whoever first posted this solution, thanks.
