Hello! Soon we will be opening out pool and have been considering an automatic pool cleaner. We have a 20x40 pool, about 25,000 gallons. Deep end is 9 foot and the shallow end is 3 foot leading to a pretty steep slope between them. So far the high end ones admit that they will get stuck in the deep end because the robot will think the slope is a wall. We tried the creepy crawly and we have yet to be able to get it to run for more than 5 minutes. Does ANYONE have a suggestion!?
