Abstract: A cleaning device contains a cleaning nozzle unit with at least one nozzle having an exit channel with a nozzle opening. The unit is mounted on a rotary shaft having a longitudinal axis and a direction of rotation and the cleaning device further includes a propeller mounted on the rotary shaft. The propeller has at least one plate shaped vane with a first plate part having a leading edge with a length and a second plate part having a trailing edge with a length, the leading edge is oriented in the direction of rotation and the trailing edge is oriented in an opposite direction. The propeller has at least one first opening between the leading edge and a neighboring trailing edge, said first opening(s) having at least one height h1, determined parallel to the longitudinal axis of the rotary shaft and between the leading edge and the neighboring trailing edge.
