Abstract
A suction nozzle for a vacuum cleaner is designed so that exhaust from a motor blower in the body of the vacuum cleaner is provided into a suction port of the suction nozzle. The exhaust provided into the suction nozzle is prevented from being discharged to the atmosphere at the point where the suction nozzle meets the to-be-cleaned surface.
