We are in process of choosing equipment for new pool build. Had pool at previous home with Kreepy Krauly Legend pool cleaner with a separate pump to run it. This new pool will only be 7’ x 28’ (rectangular) due to utility easement. Pool builder is recommending same cleaner with separate pump again. Main pool pump will be Pentair Intelliflo 2 VST variable speed.Is it really necessary to have a separate pump? Is there a better type of cleaner we should consider? We shouldn’t have any leaf debri, only pine needles.
