Claim:
A swimming pool cleaner comprising: a. a body defining a water inlet thereto and a water outlet therefrom; b. a reversible electric motor carried by the body and comprising a drive shaft; c. a filtering device carried by the body for filtering at least some water passing through the water inlet; d. a driving member mechanically connected to the reversible electric motor; e. pumping means (i) mechanically connected to the reversible electric motor, (ii) positioned at least partly within the body, (iii) being the only means for drawing water into the body, and (iv) comprising an axial pumping propeller with unidirectional pitch; and f. an electric control unit which is configured to control the reversible electric motor both (i) in a first rotation direction of the drive shaft so as to (A) drive the driving member in a first direction and (B) cause the axial pumping propeller to generate a flow of water from the water inlet toward the water outlet and (ii) in a second rotation direction opposite the first rotation direction so as to drive the driving member in a second direction opposite the first direction.
