In accordance with a preferred embodiment of the present invention the rotatable water path deflector assembly axis and the second rotatable water path deflector axis are coaxial. Alternatively, the nozzle axis, the rotatable water path deflector assembly axis and the second rotatable water path deflector axis are all coaxial.
