The invention discloses a rotary waterfall shower comprising a hollow body, transversely arranged vane wheels, a front cover arranged on the front end of the body in a sealing way and a water division member which is arranged in the body in a sealing way and can cause the vane wheels to rotate, a pinion wheel is fixedly arranged on the front end of the vane wheels in an axial direction and is meshed with output gear wheels distributed in a central symmetry way, and each output gear wheel can drive one rotary water discharge component arranged on the front end of the front cover to rotate horizontally. Water sprinkled out from the water outlet of the rotary waterfall shower can be dynamically rotated to form gainly clusters of spiral waterfall water blooms, and the shower has the effect of gentle massage.
