Based on some of the reviews provided here I was considering a Dolphin Supreme pool cleaner (M4/M5). The issue is that the specs for these cleaners state that they are good for pools up to 50 feet in length, our pool is 55 feet. The pool is not rectangular but rather an organic shape; it is a Sylvan, vintage 1992, if that helps.
I called Maytronics and they said that the limitation was in the mapping software in the cleaner and that it could not map a pool larger than 50 feet. The CS rep suggested that I might have to do two passes moving the cleaner to get it to cover the whole pool.
Thanks in advance for the help.
