A rotary sprayer and method for spraying an inner surface of an enclusure, such as a toilet bowl, with a fluid are disclosed. The rotary sprayer includes a clip (110) and a rotating nozzle (120). The clip (110) includes a fluid inlet (208) and an arm (176) having a distal end section (178). The nozzle includes a circular deflection plate, and a pair of spaced apart walls extending away from a surface of the deflection plate.The walls define a channel on the surface of the deflection plate. A passageway is in fluid communication with the channel and an end space between the walls. The fluid inlet is positioned in the end space and a spindle of the nozzle is mounted to the distal end section of the arm. Fluid exiting the fluid inlet flows through the passageway andt he channel and contacts an inner suface of at least,one ot the walls to rotate the nozzle and spray the inner suface walll of the enclusure with the fluid.
