PURPOSE: A suction port for attaching a duster of a vacuum cleaner is provided to enhance the cleaning performance of a vacuum cleaner by cleaning a room through friction between a duster attached to the bottom of a suction port and the ground. CONSTITUTION: A suction port having a duster of a vacuum cleaner consists of: a suction hole(510) formed on the front lower surface of a suction port(500) to suck air into the suction port; a couple of duster attaching plates(530) arranged at the rear of the suction hole to attach dusters(60) for cleaning a room through contact with the bottom surface; and a drive unit mounted between the duster attaching plates to rotate the plates. A user cleans a room with moving the suction port back and forth after the user attaches the dusters to the both duster attaching plates. A couple of rollers(540) slide on the bottom surface, and each drive gear(541) outside the rollers is rotated to rotate the both duster attaching plates through each gears(532). The duster attaching plates are rotated in proportion to the RPM(Revolutions Per Minute) of the rollers whenever the suction port is moved back and forth. Therefore, the cleaning efficiency of the vacuum cleaner is enhanced.
