<p>It is disclosed a vacuum cleaner nozzle comprising a housing, a rotatable brush which is adapted to brush a surface, and a turbine, wherein a suction air flow impacting on said turbine generates a first rotational torque for rotating said rotatable brush, wherein it further comprises an electric power generator for generating electric power by a rotation of said turbine; an accumulator unit for storing said electric power; and an electric motor which is adapted to generate a second rotational torque for rotating said rotatable brush, wherein said electric motor is electrically connected to said accumulator unit. The electric power generator and the electric motor could be either integrated into a single component or they could be separate components.</p> |
