A vacuum cleaner, including a cleaner body; and a dust collector provided in the cleaner body, wherein the dust collector includes a first cyclone provided within an outer case to filter foreign matter and dust from air introduced into the dust collector; a second cyclone accommodated within the first cyclone to separate fine dust from the air introduced into the first cyclone; and a screw surrounding part of the first cyclone, and configured to be rotatable in at least one direction with respect to the first cyclone, wherein the screw includes a pillar that spans a height of the mesh filter; and a scraper provided on an inner surface of the pillar facing an outer surface of the mesh filter, and configured to sweep off dust and foreign matter accumulated on the mesh filter during the rotation of the screw.

A hand vacuum cleaner may include a suction motor and fan assembly that is positioned downstream of a pre-motor filter. A post motor filter may be positioned downstream of the suction motor and fan assembly and may be in the lower end of the hand vacuum cleaner and an energy storage member may be in an upper end of the handle.

The present disclosure relates to a motor assembly improving a coupling structure of a rotor shaft and an impeller, and a cleaner including the same. The motor assembly includes a stator, a rotor including a rotor shaft including a metallic material and configured to be rotatable by electromagnetic interaction with the stator, a hub including a plastic material and including a hollow portion configured to allow the rotor shaft to pass therethrough, and a shaft coupling member positioned between the hollow portion and the rotor shaft and including a plastic material different from a plastic material forming the hub.

A vacuum cleaner assembly and vacuum cleaner with a vacuum cleaner assembly, including a suction device with a basic body with a first end with at least one suction inlet for connection with a suction tube and/or suction hose of the vacuum cleaner. Furthermore, the basic body divides at a second end into two substantially tubular suction ducts, each having a suction intake, wherein one suction arm each is associated with the suction intakes, and wherein the suction arms are provided pivotable about the associated suction duct.

The present disclosure relates to a cleaner improving the cleaning efficiency. The cleaner includes a main body, a suction device configured to suck foreign substances on a surface to be cleaned, and an extension member positioned in the rear of the suction device to connect the main body and the suction device, wherein the suction device includes a suction head including a suction port, a connection member connecting the suction head and the extension member, and a weight accommodated in the suction device and disposed between the suction port and the extension member such that the suction port is prevented from being lifted from the surface to be cleaned when the suction device moves along the surface to be cleaned.

A vacuum cleaner comprising a fan driven by a motor, wherein the fan is configured to accomplish a suction flow from a vacuum cleaner nozzle via a hand-held tube having a direction of elongation, to a permeable dust collecting container. A sensing device is provided, sensing strain in the tube along its elongate direction, and a control arrangement controls the output of the motor in response to the sensed strain. This allows the vacuum cleaner to adapt to different floor surfaces.

Provided is a vacuum cleaner. The vacuum cleaner includes a cleaner body including a moving device for moving, a suction device connected to the cleaner body to suction dusts and air and guide the suctioned dusts and air to the cleaner body, the suction device including a handle, a detection device for detecting a distance between the handle and the cleaner body, and a controller determining whether movement of cleaner body is necessary on the basis of the distance between the cleaner body and the handle, the controller controlling the moving device when the movement of the cleaner body is necessary. The controller controls the moving device to allow the cleaner body to avoid an obstacle when it is determined that an operation for avoiding the obstacle is necessary while the moving device operates.

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 surface cleaning apparatus comprises a canister body having a recess with sidewalls that extend upwardly from a platform, the platform having a pre-motor filter housing with a pre-motor filter positioned therein, wherein at least 50% of a perimeter of the pre-motor filter is recessed inwardly from the sidewalls of the recess whereby, when a pre-motor filter is positioned in the pre-motor filter housing, a portion of the platform is visible between the perimeter of the pre-motor filter and the sidewalls of the recess. An air treatment assembly is removably mountable to the canister body and seats on the recess when the air treatment assembly is mounted to the canister body.

The vacuum cleaner includes a cleaner body including a wheel for moving and a wheel motor for driving the wheel, a suction hose connected to the cleaner body, a handle connected to the suction hose, at least one detection sensor disposed in the suction hose to detect an inclination of the suction hose, and a controller controlling the wheel motor on the basis of the inclination of the suction hose detected by the at least one detection sensor.
