    摘要： A suction port assembly and vacuum cleaner having the same is disclosed. The suction port assembly includes a casing comprising a suction port which draws in dust from a surface being cleaned; a drum brush which is disposed rotatably in the casing, on an external surface of which a plurality of bristles are arranged to shake off dust from the surface being cleaned; and a rib which is disposed at a position close to the drum brush, is mounted in the casing so that its one end is in contact with the bristles, and detaches the dust from the bristles when the drum brush rotates; and wherein the bristles are contacted on a slant relative to the rib to prevent the drum brush from rotating when the casing is pulled towards a user.
