A vacuum cleaner includes a foot assembly having a suction inlet thereon, a suction source in fluid communication with the suction inlet to produce a working airflow therethrough, and a dirt container in fluid communication with the suction inlet and suction source. The foot assembly further comprises a body defined by a central portion and a pair of extension arms, a rotatable agitator on each extension arm, and a drive assembly configured to counter-rotate the agitators. The counter-rotating agitators are operable to cooperate with the suction source to direct dust and debris towards the suction inlet.

A nozzle for a vacuum cleaner and a vacuum cleaner are provided. The nozzle may include a main nozzle; at least one movable nozzle rotatably coupled to the main nozzle; and a rotary cleaner provided inside of the main nozzle and the movable nozzle that cleans a floor surface using a rotary motion. The rotary cleaner may include a main shaft rotatably provided inside of the main nozzle, and at least one auxiliary shaft provided inside of the movable nozzle and connected to the main shaft. The at least one auxiliary shaft may rotate using a rotational force transmitted from the main shaft.

New and novel structure(s) for cleaning surfaces have been disclosed. The structures, configurations and methods disclosed herein are new to this world and functionally and structurally enable that which was not possible previously. The invention at hand uniquely and inventively improves upon the known devices in this field.

A cleaner including a cleaner body having a suction motor, a nozzle that sucks in foreign substances and air from a floor surface by suction force of the suction motor, and a connection tube connected to a rear portion of the nozzle and guiding foreign substances and air sucked from the nozzle to the cleaner body. Additionally, the nozzle may include a nozzle body having a front-rear suction passage extending in a front-rear direction of the nozzle so that the foreign substances and air are sucked in, and formed so that the front-rear suction passage is connected to the connection tube, a rotation cleaning part provided so as to be rotatable below the nozzle body and having at least one rotation plate to which a mop is attached, and a driving device provided in the nozzle body and having a driving motor for rotating the rotation plate.

A nozzle of a cleaner includes a nozzle body, a rotation cleaning part having a rotation plate to which a rag is attached, a driving device provided in the nozzle body, a water tank, a water supply passage, and a water adjuster of which at least a portion is mounted on the nozzle body at a rear side thereof so as to be exposed to a rear surface or a top surface of the nozzle body. A user standing on the same floor surface as the nozzle body may manipulate the water adjuster by using his or her foot. The water adjuster can adjust an on/off operation and a rotational speed (e.g., rpm) of the pump motor.

A vacuum cleaner comprises a cleaning head having a suction nozzle adapted to be moved along a surface to be cleaned, and a hair collection assembly provided on the cleaning head and having a hair collection element adapted to collect hair from the surface to be cleaned as the cleaning head moves along the surface to be cleaned.

A cleaning head connectable to a vacuum cleaner comprises a cassette removeably mountable on the cleaning head. A rotatable bar has projecting cleaning elements engageable with a surface to be cleaned and the rotatable bar is removeably mountable in the cassette. A first cassette mounting assembly is coupled to the rotatable bar at a first end with a first spindle. A second cassette mounting assembly is coupled to the rotatable bar at a second end with a second spindle. The first and second cassette mounting assemblies have removable cover portions for shielding the first and second spindles from debris and the first cassette mounting assembly is rotatably coupled to and removable with the first spindle.

A vacuum cleaner comprises a base having a suction nozzle adapted to be moved along a surface to be cleaned, and a hair collection assembly carried by the base and having a hair collection element adapted to collect hair from the surface to be cleaned as the base moves along the surface to be cleaned.

A vacuum cleaner includes a foot assembly having a suction inlet thereon, a suction source in fluid communication with the suction inlet to produce a working airflow therethrough, and a dirt container in fluid communication with the suction inlet and suction source. The foot assembly further comprises a body defined by a central portion and a pair of extension arms, a rotatable agitator on each extension arm, and a drive assembly configured to counter-rotate the agitators. The counter-rotating agitators are operable to cooperate with the suction source to direct dust and debris towards the suction inlet.

A wheel driving device includes: a motor rotating a shaft: an input gear fixed to the shaft; at least one transmission gear meshed with the input gear to transmit power of the motor; and a final gear meshed with the transmission gear and connected with a wheel via an axis to transmit the power from the transmission gear to the wheel. The wheel driving device includes an extraction gear meshed with the final gear or the transmission gear, and a power transmission part connected with the extraction gear to transmit the power from the extraction gear to a cleaner head.
