Patent ID: 8779391

Claim:
A self-propelled system for sterilizing surfaces, the system including: a. a robotic mobile platform having an ultraviolet light source, the robotic mobile platform being configured to neutralize biological contaminants by using the ultraviolet light source to emit ultraviolet light on a surface; and b. a controller interfaced with the ultraviolet light source, i. the controller being configured to control the ultraviolet light source so as to change a level of disinfection effected by the ultraviolet light source, ii. the level of disinfection being a percentage of biological contaminants neutralized on the surface on which the ultraviolet light is emitted; and c. a light sensor configured to detect illumination of biological contaminants irradiated with light; wherein the robotic mobile platform does not have a vacuum so as to avoid suction that could spread contagions or that could suck contagions into the robotic mobile platform.
