Abstract
A cleaning robot having an exhaust air feedback function can utilize the vacuum suction force generated by a suction motor as well as spray exhaust air onto the surface to be cleaned by circulating the air using the suction motor, thereby improving foreign material removal efficiency. The cleaning robot includes a suction unit, a suction motor for drawing in foreign materials from the surface to be cleaned, along with air, through the suction unit, a dust collector for capturing the foreign materials, so that the air is exhausted through the suction motor, and an exhaust air feedback unit for feeding the air. The cleaning robot also includes a spray nozzle unit inserted into the suction unit and placed on the leading end of the suction unit, the spray nozzle unit spraying the air fed by the exhaust air feedback unit, to the surface to be cleaned.
