We just put in a pool about two years ago to the date and already need to purchase a new pool cleaner. The builder installed a Zodiac MX6 but it just could not handle the debris that was required due to the huge oak tree that was in the area. It is no longer there, we just had it cut. I am looking to purchase a new suction cleaner and would like to hear from others on which one they would recommend. Should we go back with the MX8?
