A method of controlling movement of a robotic cleaning device and a robotic cleaning device performing the method. The method comprises acquiring historical data forming a representation of an environment in which the robotic cleaning device moves, and controlling movement of the robotic cleaning device to exert a force onto an object located in the environment to move the object based on the acquired historical data.

An embodiment of the present invention provides an artificial intelligence (AI) robot for determining a cleaning route using sensor data, comprising: a sensor unit including at least one of an image sensor, a depth sensor or a shock sensor; a cleaning unit including at least one of a suction unit or a mopping unit; a driving unit configured to drive the AI robot; and a processor configured to: acquire the sensor data from the sensor unit, determine a complex area using the acquired sensor data, create a virtual wall for blocking an entry into the determined complex area, determine the cleaning route in consideration of the created virtual wall, and control the cleaning unit and the driving unit based on the determined cleaning route.

The present invention provides a cleaning unit, comprising: a columnar body part having a rotation guide opening formed on the outer circumferential surface thereof; a shaft installed to reciprocate a predetermined distance in the longitudinal direction thereof in a hollow formed in the body part; a drive part that protrudes from the shaft in the radial direction thereof; a brush part that has one side installed on the outer circumferential surface of the body part along the longitudinal direction thereof and rotates on the basis of the one side as a rotation axis; and a driven part that extends from the brush part toward the drive part, passes through the rotation guide opening, and is inserted into a rotation guide groove formed in the drive part. The rotation guide groove extends at a predetermined angle with respect to the longitudinal direction of the shaft, and as the shaft reciprocates, the driven part is guided to rotate by means of the rotation guide groove, and the brush is rotated by means of the rotation of the driven part. The cleaning unit may include a robot cleaner or a cleaner operated by means of a user's operation.

A robot cleaner includes a body to travel on a floor; an obstacle sensing unit to sense an obstacle approaching the body; an auxiliary cleaning unit pivotably mounted to a bottom of the body, to be extendable and retractable; and a control unit to control extension or retraction of the auxiliary cleaning unit based on a pivot angle formed by the auxiliary cleaning unit with respect to a travel direction of the body when the obstacle is sensed.

A surface cleaning apparatus is provided. The surface cleaning apparatus includes a dirt inlet, a rotatable brushing member, and a brush motor drivingly connected to the rotatable brushing member. The brush motor includes a plurality of field coils, a first motor sub-unit, a second motor sub-unit, and a motor controller. The first motor sub-unit includes a first rotor portion, a first stator portion, and a first field coil. The second motor sub-unit includes a second rotor portion, a second stator portion, and a second field coil. The first and second rotor portions are rotatable about a motor axis and are drivingly connected to the brushing member. The second motor sub-unit is axially spaced along the motor axis from the first motor sub-unit. The motor controller is operable to direct electric current through the plurality of field coils generating magnetic fields and driving rotation of the rotor portions.

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.

Provided is a robot cleaner including a main body including a suction portion disposed therein, a main wheel for moving the main body, wherein a vertical level of the main wheel varies in a vertical direction with respect to the main body, an auxiliary wheel disposed at a front portion or a rear portion of the main body, wherein a vertical level of the auxiliary wheel is fixed with respect to the main body, and a driving member assembly disposed in the main body, wherein the driving member assembly varies a vertical level of the main body from a floor face while rotating in forward and rearward directions of the main body, wherein the driving member assembly has different hitting radii when rotating forward and rearward.

A self-moving cleaning device includes: a base; a mobile module adjacent to the base and configured to contact a surface when the self-moving cleaning device moves on the surface; a vacuum module arranged over the base; a dust box arranged over the base and connected to the vacuum module, the dust box including a first opening and a second opening; a first suction port arranged on the base and including a first suction inlet connected to the first opening; a second suction port arranged on the base and including a second suction inlet connected to the second opening, the first suction port disposed between a front side of the base and the second suction port; a roller brush device arranged on the base and within the second suction port; and an air duct, wherein the first suction port is connected to the dust box through the air duct to thereby connect the first suction inlet to the first opening.
