Apparatus is provided for cleaning the walls of liquid containing vessels, particularly swimming pools. The apparatus is powered by suction applied to an outlet. The outlet communicates with two inlets, a first inlet being positioned adjacent the vessel surface while a second inlet is aligned toward the interior of the vessel. Motive means, preferably in the form of an axial flow turbine, is situated between the second inlet and the outlet to effect operation and mobility means preferably in the form of a pair of wheels.
