Abstract: A showerhead assembly is provided which includes a conduit, a gear train and oscillating nozzle chamber. The gear train includes a propeller, toothed pinion, and large toothed gear. Water flows from the conduit into an internal chamber within the showerhead housing. Specifically, water enters the propeller thereby causing it to rotate, the rotation of which causes the pinion to rotate, and consequently, the large gear to revolve.
