A suction nozzle assembly for a vacuum cleaner includes a nozzle body (2,101) with a contaminants suction opening, and a rotation drum (20,120) rotatably disposed at the contaminants suction opening of the nozzle body (2,101) with a plurality of protrusions (62-69) formed on an outer circumferential surface of the rotation drum (20,120). When the nozzle body (2,101) moves on a surface to be cleaned, the rotation drum (20,120) is rotated by friction force of the plurality of protrusions (62-69) against the surface to be cleaned.
