the suction nozzle having a suction port confined by an inlet duct made of transparent and ultraviolet-ray transmittable material allowing a transmission of ultraviolet rays therethrough; and
at least an ultraviolet lamp adjacent to and disposed around said suction port of said suction nozzle for projecting ultraviolet rays downwardly towards a surface to be cleaned by the vacuum cleaner for destroying bacteria directly on the surface and for projecting ultraviolet rays through the transparent suction port of said suction nozzle for killing bacteria as laden i an air stream drafted by the exhausting fan.

Abstract
A sterilizing vacuum cleaner includes at least an ultraviolet lamp disposed around a suction nozzle provided in a bottom portion of a hood secured with the cleaner housing, having a reflecting shade mounted on a back side of the ultraviolet lamp for reflecting the ultraviolet rays emitted from the lamp towards the surface to be cleaned and towards the nozzle duct made of transparent sheet and of ultraviolet-ray transmittable material, so that the dusts or pollutants containing bacteria or fungi laden on the air stream sucked by the cleaner will be sterilized by the ultraviolet lamp for hygienic purpose and for a good housekeeping in a hospital or in any other interior of a building.
