Works ok, but doesn't by any stretch of the imagination "clean the entire pool" as one of the reviews suggests. No way to adjust the run time once it's initially set, no good directions in the manual and no response from "customer service". Pool will still require manual cleaning periodically as it never seems to get the whole pool. I have wedding cake steps and it appears to be lost when it tries to climb them, flipped over, filter door came open😯. Set to floor only %26 still can't figure out the pattern...it's a round pool!😑
