A vacuum cleaner charging dock comprising a base and a bracket is provided. The bracket is arranged on one side of the base and is provided with a charging socket for charging a vacuum cleaner, while a positioning slot is arranged on another side of the base, the positioning slot is used for containing a floor brush of the vacuum cleaner, the positioning slot is provided with a plurality of convex teeth, which are used for rubbing with a rolling brush on the floor brush. The vacuum cleaner charging dock is provided with convex teeth, and the rolling brush of floor brush has deformation contact with the convex teeth. When the rolling brush starts to rotate, the convex teeth are easy to perform frictional rotation. Then dust and sewage on the rolling brush are shaken off into a positioning slot to complete the cleaning to the rolling brush, which is convenient and efficient.

A cleaner holder includes a base, a stand coupled to the base and extending upward from the base, a support body coupled to an upper portion of the stand and configured to support a cleaner, and a cleaning module support coupled to the stand and configured to support a cleaning module of the cleaner. The cleaning module may be detachably coupled to an extension tube of the cleaner.

Disclosed are a cleaning apparatus and a control method thereof. A cleaning apparatus according to the present specification, comprising a cleaning module and a main body, comprises: a motor for suctioning air outside the cleaning apparatus; a sensor which is included in the cleaning module and detects a facing distance between the cleaning module and a facing surface while the motor is operating; and a processor which controls the output of the motor on the basis of the facing distance. Thus, even without an additional operation by the user, it is possible to pre-emptively protect a user from injury by a brush that rotates while externally exposed, on the basis of the distance between the cleaning module and the floor surface.

An automatic guiding method for a self-propelled apparatus (10) is provided. The self-propelled apparatus (10) turns and irradiates when a signal light emitted by a charging dock (20) is sensed by a flank sensor (103), and changes its turn direction when another different signal light from the charging dock (20) is sensed by a forward sensor (102). The charging dock (20) switches to emit another signal light different from the signal light currently emitted when each time is triggered by the signal light emitted by the self-propelled apparatus (10). Repeatedly execute the above actions and make the self-propelled apparatus approach the light-emitting unit (202) until the self-propelled apparatus (10) reaches a charging position. It can accurately guide the self-propelled apparatus (10) to the charging position by arranging only two sensors on the self-propelled apparatus.

An extension pipe (30) is configured to allow a suction tool (70) to be connected to one end side in a pipe axis direction and a vacuum cleaner main body (10) to be connected to another end. The extension pipe (30) includes a power-receiving portion (36) configured to receive and supply electric power to be fed to a battery (17a) provided to the vacuum cleaner main body (10).

A handheld air purifier may include a suction body provided with a suction surface having a first and second frame, a fan to suction air, and a filter to filter suctioned air, a bending portion extending rearward from the suction body to bend upward, and a handle extending further from the bending portion and held by the user. The second frame may be provided behind the first frame and may include a protrusion that penetrates through the first frame to create a gap between the suction surface and a garment being treated to promote a free airflow through the handheld air purifier.

A surface cleaning apparatus, such as a portable surface cleaning apparatus is powered by one or more ultracapacitors and a charging unit for same is provided.

A surface cleaning apparatus has a suction motor actuator that is actuatable to actuate the suction motor to operate in a low mode of operation and to operate in a high mode of operation. A first power pack provides a first level of on board power that is available to power the surface cleaning apparatus. A second power pack provides a second level of on board power is available to power the surface cleaning apparatus, the second level of on board power is greater than the first level of on board power. Each of the low and high modes of operation are enabled when the first power pack is provided to power the surface cleaning apparatus and when the second power pack is provided to power the surface cleaning apparatus. When the second power pack is provided to power the surface cleaning apparatus, an operating power level provided to the suction motor during at least one of the low and high modes of operation is increased.

A mobile robot of the present disclosure includes: a traveling unit configured to move a main body; a cleaning unit configured to perform a cleaning function; a sensing unit configured to sense a surrounding environment; an image acquiring unit configured to acquire an image outside the main body; and a controller configured to generate a distance map indicating distance information from an obstacle for a cleaning area based on information detected and the image through the sensing unit and the image acquiring unit, divide the cleaning area into a plurality of detailed areas according to the distance information of the distance map and control to perform cleaning independently for each of the detailed areas. Therefore, the area division is optimized for the mobile robot traveling in a straight line by dividing the area in a map showing a cleaning area.

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.
