ABSTRACT:
A self-cleaning mirror comprising a rotor having a shaft, a disc on an end of the shaft, constituting the outer end of the shaft, presenting a reflective surface at its outer face, and a plurality of vanes extending laterally with respect to the shaft. The rotor is mounted for rotation within a housing having an open end with the reflective surface of the rotor being disposed adjacent the open end of the housing. An inlet port directs fluid under pressure from a source thereof against the vanes at an angle causing the rotor to rotate, whereby the rotor expels, by centrifugal force, water or other flowable material which may come into contact with its reflective surface thereby keeping it clean.
