A dust remover for a vacuum cleaner is provided inside a filter and is rotated by a motor. The dust remover includes: a rigid rotary member perpendicularly coupled to an output shaft of the motor to be rotated according to a rotation of the output shaft; a rotating buffer member assembled with an end portion of the rigid rotary member to be rotatable around a rotary shaft that is in parallel with the output shaft; a striking member having an end portion fixed to the rotating buffer member and another end portion contacting the filter; and an elastic member having an end portion coupled to the rotating buffer member and another end portion coupled to the rigid rotary member so as to apply an elastic recovery force to the rotating buffer member to rotate in a direction in which the rigid rotary member rotates.

A vacuum cleaner including a main body and a filter assembly. The main body includes a vacuum motor for drawing a flow of air through the vacuum cleaner. The filter assembly includes a first filter, and a filter housing configured to form part of an outer surface of the vacuum cleaner. The filter assembly defines a longitudinal axis, and a through-hole which runs along the longitudinal axis through the filter assembly. Also disclosed herein is a filter assembly for said vacuum cleaner.

A surface cleaning apparatus having an air flow path from a dirty air inlet to a clean air outlet and including an air treatment member, a suction motor and a filter assembly in the air flow path. The filter assembly includes at least two spaced apart physical filter elements with the upstream face of the second filter facing the downstream face of the first filter element. The filter assembly is configured to prevent air from bypassing the first physical filter media. The filter assembly includes a gap between the first filter element and the second filter element that acts as a header and reduces the flow rate of air incident on the second filter element.

A dust bin and a vacuum cleaner combination provided with the dust bin are provided. The dust bin includes a dust chamber, a dust inlet detachably connected to a dust suction apparatus, and a sealing structure for implementing the sealing between the dust suction apparatus and the dust bin. The dust suction apparatus has a dust outlet joined to the dust inlet. The vacuum cleaner combination includes a dust suction apparatus and a dust bin detachably connected to the dust suction apparatus. The dust suction apparatus has a housing and a dust cup assembly connected to the housing. The dust cup assembly includes a cup body and a filter apparatus disposed in the cup body. Compared with the prior art, in the present invention, a detachable multi-purpose dust bin with a simple structure is disposed, so that the dust collection chamber of the vacuum cleaner is flexibly increased.

A handheld vacuum cleaner including a fluid flow path, a main body, a fluid flow motor, a battery, and a cyclone chamber. The fluid flow path extends from a dirty air inlet to a clean air outlet, and the main body includes a handle. The fluid flow motor is positioned in the fluid flow path. The battery is positioned below the fluid flow motor. The cyclone chamber is in the fluid flow path transverse to the dirty air inlet. The cyclone chamber includes a first end wall and a second end wall, a cyclone chamber axis passing through the first end wall and the second end wall, a cyclone dirty fluid inlet, and a cyclone clean fluid outlet. The first end wall and the second end wall of the cyclone chamber both intersect a common horizontal plane when the handheld vacuum cleaner is positioned on a horizontal surface.

A handheld vacuum cleaner includes a housing, motor, filter access door, filter, and dirt cup movably coupled to the housing. The housing defines a top, bottom, motor chamber, dirty air inlet, handle, clean air outlet, and air flow path. The air flow path is routed from the dirty air inlet to the clean air outlet. The motor is disposed in the motor chamber and defines a motor axis. The filter access defines a filter chamber with the housing. The filter is disposed in the filter chamber and defines a filter axis. The dirt cup defines a dirt cup axis extending parallel to the motor axis and filter axis. The filter access door is located below the filter axis. When the filter axis door is removed, the filter is removable in a downward direction from the filter chamber.

A hand vacuum cleaner has a dual first stage cyclones.

A self-cleaning dust cylinder assembly, including a dust collection assembly, a filter and a cleaning assembly. The dust collection assembly includes a dust collection cylinder, the upper end of the dust collection cylinder is provided with an opening, and the lower end of the dust collection cylinder is provided with a dust suction port. The filter inlet side of the filter is located above the dust suction port, and the filter outlet side is connected to the opening of the dust collection cylinder. The cleaning assembly includes a cleaning brush, and the cleaning brush is installed in the dust collection cylinder and cleans the filter with the movement of the dust collection cylinder, so as to clean the dust stains and other garbage attached on the filter into the dust collection cylinder.

A hand vacuum cleaner has an information display device provided on a rear wall of the rear end of the hand vacuum cleaner.

A cleaner is disclosed. The cleaner includes: a housing having an introduction opening through which air is introduced; a filtering unit configured to be mounted in an inner space of the housing, and defining a dust collection space between the filtering unit and an inner surface of the housing; and a cleaning unit surrounding the filtering unit and configured to be raised and lowered. When the cleaning unit is in an initial position at least a portion of the cleaning unit is connected to an air introduction path extending from the introduction opening such that the cleaning unit guides a flow of introduced air. A guide edge extends from a lower portion of the cleaning unit toward a bottom of the dust collection space, and a surface of the guide edge facing the inner surface of the housing is inclined.
