    Abstract: The invention relates to a water surface cleaner method and apparatus for suctioning flotage such as oil, pollutants, floating debris and the like from water surfaces. A water guide passage extends between front and rear ends of a floating body. Exhaust flow of a pump generates an effective surface current in front of the body and through the passage. A flotage collecting section is provided at the rear end of the water guide passage. Buoyant means support the flotage collecting section at and under the water surface. A propeller system is connected to a radio control receiver provided on said body.
