A nozzle includes: a housing having a chamber formed in the housing and a front opening formed on a front side of the housing; a rotation cleaning part accommodated in the chamber and to clean a floor; a partition member provided in the chamber to partition the chamber into two areas and of which at least a portion is in contact with the rotation cleaning part; a driving unit to rotate the rotation cleaning part; and a connection tube connected to the housing and configured to transfer air introduced through the front opening to a dust container of the cleaner, wherein a lower passage formed below the rotation cleaning part and an upper passage formed above the rotation cleaning part are provided in the chamber, and a portion of the partition member is recessed to define the upper passages.

A water-absorbing cyclone dust cup for secondary dust-air separation comprises a dust cup cover body and a dust cup main body. The dust cup main body comprises a cup body portion, a primary cyclone arranged in an opening of the dust cup main body, and a secondary cyclone comprising a secondary cyclone main body provided with a ventilation hole defined in a center. At least one air guiding portion is arranged on a bottom end surface of the secondary cyclone main body. The air guiding portions comprise spiral air guiding plates, spiral air guiding passages formed by the spiral air guiding plates around the ventilation hole, and air guiding passage baffles enclosing first ends of the spiral air guiding plates. the spiral air guiding passages are formed by spiral longitudinal extension along the center line direction of the ventilation hole.

A vacuum cleaner basically includes a motor, first and second inlets and a cover. The motor is configured to create flow through a suction path. The first inlet and the second inlet are disposed in the housing in fluid communication with the suction path. A cover is pivotably disposed in the second inlet. The cover is movable between a first position in which the second inlet is substantially covered to substantially prevent fluid from flowing through the second inlet and a second position in which fluid is allowed to flow through the second inlet.

A vacuum accessory tool has a nozzle body with upper and lower housings, a working air conduit provided on the nozzle body and adapted to be connected to a suction source remote from the nozzle body, a suction nozzle in fluid communication with the working air conduit, and a rotatable retaining ring securing the upper and lower housings together.

A surface cleaner that includes an accessory body removably coupled to a base. A nozzle has a first nozzle portion having a first nozzle passageway attached to the base and a second nozzle portion having a second nozzle passageway attached to the accessory body and removable with the accessory body. The first nozzle portion and second nozzle portion are releasably coupled connecting the first and second nozzle passageways along an airpath in fluid communication with a collection container when the accessory body is coupled to the base. The first nozzle passageway forms a suction inlet when the accessory body is coupled to the base and the second nozzle passageway forms the suction inlet in communication with the collection container and the suction source when the accessory body is uncoupled from the base.

A vacuum accessory tool comprises a nozzle body defining an interior, with an opening formed in the nozzle body and a working air conduit provided on the nozzle body in fluid communication with the opening via the interior. A hair removal assembly is associated with the nozzle body, and can include nubs from a flexible polymeric material adapted to generate an electrostatic charge when the tool moves over and in contact with a carpet surface.

A cleaner head for a vacuum cleaner that comprises a pair of rotary agitators and one or more wheels. The agitators rotate in opposite directions, and the wheels are moveable between a deployed position and a retracted position. The wheels contact a floor to be cleaned when in the deployed position, and the wheels are lifted clear of the floor when in the retracted position such that the cleaner head is supported on the floor solely by the agitators.

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.

A nozzle includes: a housing having a chamber formed in the housing and a front opening formed on a front side of the housing; a rotation cleaning part accommodated in the chamber and to clean a floor; a partition member provided in the chamber to partition the chamber into two areas and of which at least a portion is in contact with the rotation cleaning part; a driving unit to rotate the rotation cleaning part; and a connection tube connected to the housing and configured to transfer air introduced through the front opening to a dust container of the cleaner, wherein a lower passage formed below the rotation cleaning part and an upper passage formed above the rotation cleaning part are provided in the chamber, and a portion of the partition member is recessed to define the upper passages.

An industrial sweeper operates by rolling along a floor to be cleaned, pushed or pulled, including: a brush with a horizontal axis depending on the use position of the industrial sweeper on a horizontal floor, a collecting pan for collecting dirt swept by the brush, the collecting pan mounted and able to pivot between a closed and working position and a wide open position allowing the pan to be emptied, a suction turbine downstream of the collecting pan suctioning dust into the collecting pan when in closed position, two wheels for resting on the floor, an air filter, an unclogging mechanism for unclogging the air filter. The air filter is fixed on the collecting pan and the unclogging mechanism includes an end stop to block travel of the collecting pan in its wide open position, the end stop causing a shock at the end of the collecting pan opening movement.
