I apologize as I am sure this has been asked multiple times, but I am stuck on what cleaner to get. I purchased a Dolphin DX4 last week and returned it within 3 days as it missed about half of my 16 X 34 inground pool. I have read a million reviews on all sorts of cleaners and have no idea what to get. I am not concerned with price, I just want one that works and cleans the entire pool. I have been using a Kreepy Krawly for years and it does a good job. I am just tired of baby sitting it and would rather have something that does not use my pump. I have a vinyl pool liner if that matters. I live in Minnesota so the pool is usually open from May through September.
