Abstract
The invention relates to an apparatus for cleaning a surface which is immersed in a liquid, comprising a hollow body, guiding and driving members, a filtration chamber in the hollow body, at least one liquid inlet, at least one liquid outlet out of the hollow body, at least one axial pumping propeller, a single reversible electric motor whose drive shaft, in order to move it, is simultaneously mechanically connected to at least one motorized member and to each pumping propeller. In a first rotation direction of the drive shaft, each motorized member is driven in a forward direction, and each pumping propeller generates the flow of liquid in the normal direction ensuring the cleaning of the immersed surface. In a second rotation direction of the drive shaft, each motorized member is driven in a backward direction opposite the first direction.
