Abstract
A self-propelled skimmer is provided for removing debris from the surface of a pool. A pump driven propulsion system intakes water at one end and forcefully expels it at the other end. A filter is located at the intake to trap debris for ultimate removal and disposal. To clear the entire surface of the pool, the expulsion of the liquid is randomly altered in a center-right-left sweep. A pressure sensitive transducer or switch is provided at the front of the skimmer to activate a reverse movement if the skimmer front impacts a pool edge or other obstacle.
