Abstract
A spot cleaning apparatus has a housing, a fluid distribution system, a fluid recovery system, an agitation system, at least one UV light emitting element, an optional steam generator, and a controller to automatically monitor and control inputs and outputs to the systems for spot and stain removal and surface sanitization without attendance by a user. A suction nozzle, agitation machine, and optionally, at least one UV light emitting element are mounted to the housing for movement over the surface to be cleaned relative to a stationary housing. Optionally, the spot cleaning apparatus can be operated in manual mode.
