A pulsating fluid nozzle is disclosed which comprises a body having an inner chamber and an outer chamber separated by a cylindrical wall. The inner chamber is supplied with fluid through a fluid outlet, and the outer chamber supplies fluid to the fluid outlets. The cylindrical wall has a port through which fluid can flow from the inner chamber to the outer chamber. A rotor is mounted for rotation in the outer chamber. The rotor has a blade extending from an annular hub which is adapted to fit around the cylindrical wall and block the flow of fluid through the port. The hub has an opening adapted to intermittently coincide with the port as the rotor turns to permit the flow of fluid through the port to produce a pulsating flow. The blade is adjacent to the opening and positioned to be contacted by a stream of fluid flowing through the port when the opening coincides with the port. The contact by the stream of fluid propels the blade to turn the rotor. The nozzle produces a pulsating flow without using a special pulsating pump, and can utilize the full maximum flow of fluid through the flexible hose connected to the fluid inlet of the nozzle.
