Abstract
A method and apparatus powered from the suction side of a pump for cleaning the interior surface of a pool containment wall and the upper surface of a water pool contained therein. The apparatus includes an essentially unitary cleaner body and a controller for selectively causing the body to move either in a forward direction or a non-forward direction. The controller includes (1) a periodic control device for alternately defining forward and non-forward states and (2) a motion responsive control device defining a first condition when the forward motion of the body exceeds a certain threshold and a second condition when the forward motion of said body is less than said threshold.
