A cleaner includes: a suction motor that generates suction force; a dust separation unit that separates dust from air sucked by the suction force; a motor housing that covers the suction motor; a flow guide that surrounds an outer side of the motor housing and guides air discharged from the dust separation unit to the suction motor; and a body that forms an external appearance by surrounding the flow guide and guides air discharged from the suction motor together with the flow guide.

The present disclosure relates to a cleaner system including: a cleaner; a cleaner station; and an imaginary plane including an imaginary suction flow path through line penetrating a suction flow path in a longitudinal direction and an imaginary suction motor axis defined by extending a rotation axis of a suction motor, in which when the cleaner is coupled to the cleaner station, the plane penetrates at least a part of the cleaner station, such that a center of gravity of the cleaner is disposed to pass through a space for maintaining balance of the station, and as a result, it is possible to stably support the cleaner and the station while preventing the cleaner and the station from falling down.

A cleaning device and a method therefor are provided. The cleaning device includes a vacuum cleaner including a dust collecting container and a docking station to which the dust collecting container is coupled. The docking station includes a suction device configured to move air from the dust collecting container to inside of the docking station, a collector configured to collect a foreign substance that is moved together with the air by driving of the suction device, a suction flow path along which air moves inside the docking station, a flow adjusting device configured to open or close the suction flow path, and at least one processor configured to control the suction device to operate based on the dust collecting container being coupled to the docking station, and control the flow adjusting device to periodically open and close the suction flow path in a state in which the suction device operates.

A surface cleaning apparatus has a cyclone chamber provided in an air flow path. The cyclone chamber has a screen assembly with an outlet section, a longitudinally spaced apart distal section and a longitudinally extending porous section. The outlet section includes a non-porous member extending longitudinally inwardly an outlet section length from an outlet end of the outlet section to a longitudinally inwardly positioned inlet end of the outlet section. The outlet end of the outlet section overlies a cyclone air outlet. The porous section extends longitudinally inwardly from an outlet end of the porous section that is located at the inlet end of the outlet section. The distal section has a distal section length in the longitudinal direction that is greater than the cyclone outlet port length.

A mobile robot of the present disclosure emits a first patterned light downward and forward from a main body on a floor of an area to be cleaned and a second patterned light upward and forward from the main body, determines an obstacle based on an image of each emitted patterned light which is incident on the obstacle, and senses a tilt of the main body to compensate for the tilt. In this manner, an obstacle may be determined accurately, and after the tilt compensation, redetermination is made as to whether it is possible to pass through, so as to enable the mobile robot to pass through or bypass the obstacle. Accordingly, the mobile robot may reach a wider area to be cleaned, thereby extending the area that may be cleaned, and enabling fast determination and operation for effective traveling, such that the mobile robot may escape from an obstacle without being limited thereby.

A robot cleaner comprising: a cleaner body including a wheel unit and a controller controlling driving of the wheel unit; a suction unit disposed to protrude from the cleaner body, the suction unit sucking air containing dust; and a sensing unit disposed at the front of the cleaner body in which the suction unit is disposed, wherein at least one portion of the sensing unit is disposed to overlap with the suction unit in the top-bottom direction of the cleaner body.

A autonomous cleaner includes: a cleaner body including a wheel unit for autonomous traveling; a suction unit provided to protrude from one side of the cleaner body, the suction unit sucking air containing dust; a sensing unit provided at the one side of the cleaner body; a dust container accommodated in a dust container accommodation part formed at the other side of the cleaner body, the dust container collecting dust filtered from sucked air; and a dust container cover hinge-coupled to the cleaner body to be rotatable, the dust container cover being provided to cover a top surface of the dust container when the dust container cover is coupled to the dust container.

A charging stand (100) for a vacuum cleaner (200) includes: a body (1); and a pedal (2) disposed on the body (1) and pivotable between a first position and a second position, wherein when the pedal (2) is in the first position, the vacuum cleaner (200) is suitable to be placed on the pedal (2) to be charged.

A vacuum cleaner nozzle having a rotatable member for picking up particles from a surface to be cleaned, and an external cleaning apparatus for removing articles entangled to the rotatable member. The nozzle includes a support surface provided on a radially projecting member of the rotatable member, and a cleaning member provided on the external cleaning apparatus. During rotation of the rotatable member, the cleaning member co-operates with the support surface to remove entangled articles from the rotatable member.

An electric vacuum cleaning apparatus including an autonomous robotic vacuum cleaner that autonomously moves between surfaces to be cleaned and collects dust and a station fluidly connectable to the autonomous robotic vacuum cleaner. The autonomous robotic vacuum cleaner includes: a container body accumulating collected dust, the container body including: a bottom wall including a disposal port; and a disposal lid opening and closing the disposal port. The station unit includes: a dust transfer pipe connected to the disposal port; a secondary dust container accumulating dust; and a secondary electric blower that generates negative suction pressure in the dust transfer pipe via the secondary dust container. At least one irregularly shaped ventilation groove that causes air to flow below the dust within the container body by the negative pressure generated by the secondary electric blower is provided to the inner surface of the bottom wall of the container body.
