A pair of first water jet nozzles are formed on an end section of the spray arm, while a pair of second water jet nozzles are formed on the spray arm axially inside the first nozzles and spaced apart from the first nozzles by a distance. A deflector for guiding water jets from the first and second nozzles is provided on the first and second nozzles. The rotary blade disc control unit is placed in the spray arm under the jet nozzles and periodically alternately rotates the spray arm in opposed directions.
