Abstract: This invention deals specifically with the use of ultraviolet light emitters within a vacuum cleaner, where the lights are used to neutralize bacterial contamination. The air and debris entering into the vacuum is exposed to one or more ultraviolet light sources, with the resulting radiation causing the bacterial contaminants to be neutralized. The vacuum used may be an upright bag vacuum, an upright bagless vacuum, a floor type vacuum, or a shop type vacuum. Multiple chambers are provided, in which the lights are disposed in secondary chambers, in addition to any lights used at the point of initial filtration.
