摘要： An extraction cleaning machine includes a housing with a fluid delivery system that includes a fluid distributor for delivering a cleaning fluid to the surface to be cleaned. A fluid extraction system includes a suction nozzle for recovering soiled cleaning fluid from the surface. A steam delivery system is operably coupled to the housing and supplies steam or heated liquid to the surface. A controller is operably coupled to the steam delivery system and at least one ultraviolet light emitting element to selectively control the steam delivery system in accordance with a first timed duty cycle to generate at least one of the steam and the heated liquid that is supplied to the surface and the at least one ultraviolet light emitting element to emit ultraviolet light to the surface in accordance with a second timed duty cycle.
