A nozzle discharge assembly includes a housing having a connection for receiving a pressurized supply of liquid and a nozzle having a discharge orifice movable relative to the housing. A mechanism controls a movement of the discharge orifice so that the discharge orifice moves in a pattern relative to the housing for creating a substantially helical stream of liquid when the pressurized supply of liquid flows through the discharge orifice.
