I would like to purchase a robotic cleaner for my 16 x32 vinyl liner pool. I say entry level because I cant go much above $750-$800. I want a cleaner that I can maintain myself. Have used suction side cleaner for years with mixed results. I like the robotic type so I can get away from hoses and having my skimmer tied up plus I do get a few acorns and they sometimes will jam the impeller of the cleaner. Any ideas?
