A suction cleaner nozzle has a nozzle body enclosing an agitator chamber, which has an elongated suction inlet opening. An agitator is disposed in the agitator chamber such that the agitator extends partially through the suction inlet opening for agitating a surface to be cleaned. A duct is connected to the nozzle body and located adjacent the agitator chamber. The duct extends parallel to the rotative axis of the agitator. A turbine rotor is rotatably connected to the nozzle body and operatively connected to the agitator.
