Abstract: A cleaning robot may determine a three-dimensional model of a physical environment based on data collected from one or more sensors. The cleaning robot may then identify a surface within the physical environment to clean. Having identified that surface, the robot may autonomously navigate to a location proximate to the surface, position an ultraviolet light source in proximity to the surface, and activate the ultraviolet light source for a period of time.

Abstract: Provided are a headgear stand and a headgear cleaner that is small-sized and has low power consumption, and that is capable of sterilizing and deodorizing headgear made of any material. A headgear cleaner 1-1 is provided with an ozone generator 2 and a voltage supply part 5. The ozone generator 2 is constituted from an ozone generator body 3-1 and a connecting part 4. The ozone generator body 3-1 forms a shape in which twelve leaf parts extend radially. The voltage supply part 5 supplies a voltage necessary for generating ozone to the ozone generator 2.
Abstract: Among other things, techniques are described for self-cleaning door handles. A door handle for a vehicle includes a housing including a hand grip; a hygienic film that is formed around a portion of a circumference of the hand grip; a plurality of cylindrical rollers rotatably connected to the housing and are configured to rotationally guide the hygienic film along the portion of the circumference of the hand grip; and a light that is configured to emit electromagnetic radiation in an ultraviolent spectrum and configured to irradiate at least one portion of the hygienic film to reduce a quantity of bacteria on the at least one portion of the hygienic film.
