A docking station for a robotic vacuum cleaner may include a suction motor, a collection bin, and a filter system fluidly coupled to the suction motor. The suction motor may be configured to suction debris from a dust cup of the robotic vacuum cleaner. The filter system may include a filter medium to collect debris suctioned from the dust cup, a compactor configured to urge a first portion of the filter medium towards a second portion of the filter medium such that a closed bag can be formed, and a conveyor configured to urge the closed bag into the collection bin.

A cleaner station and a method of controlling the same are provided, the method including: a dust bin fixing step of holding and fixing, by a fixing member of the cleaner station, a dust bin of a cleaner when the cleaner is coupled to the cleaner station; a door opening step of opening a door of the cleaner station when the dust bin is fixed; a cover opening step of opening a discharge cover configured to open or close the dust bin when the door is opened; and a dust collecting step of collecting dust in the dust bin by operating a dust collecting motor of the cleaner station when the discharge cover is opened such that a dust passing hole is opened by detecting coupling of the cleaner without a user's separate manipulation and the dust in the dust bin is removed by operation of the dust collecting motor.

A cleaner includes: at least one cyclone configured to separate dust from suctioned air; a dust container configured to store the dust separated by the at least one cyclone; a dust compressor provided inside the dust container; and a lifter configured to move the dust compressor within the dust container.

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 cleaner includes: at least one cyclone configured to separate dust from suctioned air; a dust container configured to store the dust separated by the at least one cyclone; a dust compressor provided inside the dust container; and a lifter configured to move the dust compressor upward and downward.

The present disclosure relates to a vacuum cleaner for separating and collecting dust and other contaminants by using a multi-cyclone and a mesh filter, including a cleaning unit for sweeping dust and foreign materials attached to the mesh filter along an outer circumferential surface of the mesh filter, and a rotation unit coupled to the cleaning unit for rotating the cleaning unit relative to the mesh filter, whereby the cleaning unit can clean a surface of the filter automatically or manually during an operation of the cleaner, so that the filter surface can be kept clean, and a load on a fan unit caused due to foreign materials or dust can be reduced.

Provided is a vacuum cleaner including a cleaner body of which a center of gravity is disposed at a rear side further than a rotating center thereof; one pair of moving wheels provided at both side surfaces of the cleaner body and configured to rotatably support the cleaner body and also to be rotated for travelling; and a rear wheel unit provided at a bottom surface of the cleaner body and configured to elastically support the cleaner body at a rear of the pair of moving wheels, wherein the rear wheel unit includes a supporting part rotatably installed at the bottom surface of the cleaner body and rotated in a rotating direction of the cleaner body; an elastic portion configured to extend from one side of the supporting part and to be elastically deformed by being in contact with the bottom surface of the cleaner body when the supporting part is rotated; a rotating member shaft-coupled to the supporting part and installed to be rotatable in a direction intersecting with a rotating direction of the supporting part; and a rear wheel installed at the rotating member and rolled while being in contact with the ground.

Provided is a vacuum cleaner separating and collecting dust, or the like, using a multi-cyclone and mesh filter. The vacuum cleaner includes a cleaning unit sweeping dust and foreign objects clinging on the mesh filter down along an outer circumferential surface of the mesh filter and a rotary unit coupled to the mesh filter and relatively rotating the mesh filter with respect to the cleaning unit. Since the cleaning unit automatically/manually cleans a surface of the filter during an operation of the cleaner, the surface of the filter may be maintained to be clean and a load applied to a fan unit due to a foreign object or dust may be reduced.

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; a screw provided at a lower side of and surrounding the first cyclone, and having at least one vane spirally extended along a flow direction of the air introduced into the outer case to induce the inflow of foreign matter and dust filtered by the first cyclone into a first storage section.

Provided is a vacuum cleaner including a cleaner body; a moving wheel provided at each of both side surfaces of the cleaner body, rotated for travelling of the vacuum cleaner and configured to support the cleaner body to be rotatable in normal and reverse directions; a wheel motor assembly connected to the moving wheel and configured to rotate the moving wheel for the travelling of the vacuum cleaner; a main motor provided inside the cleaner body, located at a rear side further than a vertical extension line of a rotating center of the moving wheel and driven to suction dust; and a battery provided inside the cleaner body, located at the rear side further than the vertical extension line of the rotating center of the moving wheel and configured to provide electric power to the main motor and the wheel motor assembly, wherein a center of gravity of the cleaner body is located at a rear of the vertical extension line of the rotating center of the moving wheel due to an arrangement of the main motor and the battery.
