An AI robot for cleaning in consideration of a user's action includes a camera to acquire a first image data for the user, a cleaning unit including a suction unit and a mopping unit, a driving unit configured to drive the AI robot, and a processor to determine the user's action using the first image data, determine a cleaning schedule in consideration of the user's action, and control the cleaning unit and the driving unit based on the determined cleaning schedule.

A method for controlling a suction device, in which the suction device includes at least one electric motor at least for generating a suction function, includes at least detecting vibration data on a suction hose of the suction device, evaluating the vibration data by comparing it with comparison data and generating a comparison result, and controlling the electric motor in accordance with the comparison result.

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.

A dust cup assembly (100) and a handheld cleaner (1000) having the same are provided. The dust cup assembly (100) includes: a cup casing (1); a device housing (2) configured as a tube shape and disposed in the cup casing (1), wherein an outer end face of the device housing (2) at an axial side thereof abuts against or extends beyond a partial inner surface of the cup casing (1), and a dust removal chamber (A1) is defined between an inner surface of the cup casing (1) and an outer peripheral surface of the device housing (2) and surrounds the device housing (2) along a circumferential direction of the device housing (2); and a negative pressure device (3) located within the device housing (2) and enabling dusty air to enter the dust removal chamber (A1) for dust and air separation.

In order to accomplish a solution task of the present disclosure, a cleaner hand according to an embodiment of the present disclosure may include a pipe configured to transfer at least one of air, dust, and foreign matter to a drive unit that generates a suction force, a grip portion connected to the pipe, and formed to be gripped by a user, a sensor unit disposed in the grip portion to sense information related to whether or not the grip portion is gripped by the user, and a controller configured to control the drive unit based on the sensed information.

Method for operating a dirt collecting device for a sweeping vehicle or for a vacuum cleaner nozzle of a floor or upright vacuum cleaner, which each comprise a suction fan with controllable speed and/or power, wherein in a first method step, the suction power of the suction fan is set at such a low level that the suction pressure in the dirt collecting device or the vacuum cleaner nozzle is merely sufficient to convey and deposit the absorbed coarse dirt into the intermediate container, and to convey the absorbed fine dirt into a downstream collection container, (normal operation); and that in a second method step, the filling level in the intermediate container is detected with respect to the coarse dirt deposited therein; and that in a third method step, if the filling level in the intermediate container is exceeded, the suction power of the suction fan is increased such that the coarse dirt, which is temporarily deposited in the intermediate container, becomes dispersible and is conveyed into the downstream collection container (emptying mode).

An upright surface cleaning apparatus comprises rear wheels that are moveable in a longitudinal direction and/or a lateral direction, which is transverse to the longitudinal direction, upon reconfiguring the upright surface cleaning apparatus between a storage position and an floor cleaning position.

A method for adjusting at least one parameter range of a device parameter of a floor treatment device for treating a surface. The parameter range is available on the floor treatment device and depends on a floor type of the surface to be treated. The parameter range comprises a defined scope of values of the device parameter selected by the user for the treatment of the surface. The user moves the floor treatment device over the surface to be treated during an adjustment process, wherein a limiting device parameter, which is dependent on the nature of the surface and upon its use for the treatment of the surface leads to a predefined fault, is automatically determined during the movement of the floor treatment device, and wherein the parameter range is automatically adjusted based on the determined limiting device parameter which defines a range end of the parameter range.

Disclosed is a central vacuum system. The central vacuum system comprises a first vacuum device, a second vacuum device, and a hose connected between the first vacuum device and the second vacuum device; the first vacuum device and the second vacuum are controlled by a linked switch, interior of the hose remains positive or slightly negative pressure. A self-operated differential pressure regulating valve arranged at the end of the hose is capable of generating corresponding air resistance under different airflow rate so as to maintain the interior pressure of the hose at a stable slightly positive or negative pressure.

A vacuum cleaner for air pollution prevention includes a main body, a blower, a filtering and cleaning assembly, and a gas detection module. The main body is configured to form a flow-guiding path. The blower is disposed in the flow-guiding path to guide air convection. The filtering and cleaning assembly is disposed in the flow-guiding path to filter and clean the air pollution source in the air guided by the blower. The gas detection module is disposed in the flow-guiding path to detect the air pollution source and transmits a gas detection data.
