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