The invention relates to a device for cleaning a surface submerged in a liquid, comprising: a hollow body; guiding and driving members (5, 6); a filtration chamber in the hollow body; at least one liquid inlet; at least one outlet for discharging liquid from the hollow body; at least one axial pumping impeller (10); and a single reversible electric motor (8), the drive shaft of which is mechanically connected to at least one motor member and to each pumping impeller simultaneously in order to drive same. In a first drive shaft (9) direction of rotation, each motor member is driven forwards and each pumping impeller generates a flow of liquid in the normal direction, thereby cleaning the submerged surface. In a second drive shaft (9) direction of rotation, each motor member is driven backwards, opposite the aforementioned forward direction. |
