    Abstract: A vacuum cleaner including: a cleaner body configured to generate a suction force; and a suctioner configured to have a brush drum rotatably provided on a suction port sucking foreign objects by the suction force. The brush drum includes a cylindrical drum, a blade assembly provided on an outer circumferential surface of the drum to extend along a rotational shaft direction, and a cleaning member provided on the blade assembly to clean dust or the foreign objects on a cleaning surface. The blade assembly includes a cleaning member support part configured to accommodate and support a part of the cleaning member and a stopper provided in the cleaning member at intervals to restrict the cleaning member from being deformed in an opposite direction to a rotational direction of the brush drum.

    Abstract: A vacuum cleaner includes a foreign-substance suction unit having a drum brush to suck foreign substances by the suction power rotating on a floor to be cleaned. The drum brush includes a rotary body having a cylindrical drum and foreign-substance collecting grooves formed at opposite end portions of the drum along a circumferential direction; a cleaning member disposed on a circumferential surface of the drum; at least one nozzle spirally extended across the cleaning member along a lengthwise direction of the drum to guide foreign substances toward the foreign-substance collecting groove; and a foreign-substance winding portion disposed in a portion of the foreign-substance collecting groove to wind the guided foreign substances. The drum brush may effectively guide, wind, and cut a hair and the like foreign substances on a carpet and the like bottom, thereby effectively preventing the hair and the like foreign substances from being piled up.

    Abstract: Disclosed is a vacuum cleaner with a drum brush. The vacuum cleaner includes: a cleaner body configured to generate suction power; and a foreign object suctionor configured to suck foreign objects by the suction power. The foreign object suctionor includes a cylindrical drum brush and a drum support configured to house a part of the drum brush and rotatably support the drum brush. The drum support includes a drum housing part configured to have a shape corresponding to an outer circumferential surface of the housed drum brush, a scraper configured to be provided in the drum housing part to remove foreign objects attached to the drum brush, and a foreign object stopper configured to be provided in one area of the drum housing part at a predetermined inflow blocking distance along a rotation direction of the drum brush from the scraper. As a result, the vacuum cleaner may effectively prevent the drum brush and the scraper from being abraded or damaged by rotating with the drum brush without removing certain foreign objects.
