A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.

A mobile robot and a control method therefor, according to the present invention, are configured to determine whether a received signal is a pre-set signal and distinguish noise caused by overlapping of signals to control the operation of a sensor for detecting an obstacle according to an operation state of a main body such that transmission of a detection signal is limited, and thus has effects of the obstacle being easily detected by distinguishing each signal, the main body returning to a charging stand, and signal interference being minimized for a plurality of sensors using a signal of the same wavelength band.

A floor treatment appliance with a replaceable change component, a detection device for detecting an actual parameter that is influenced by wear of the change component, an evaluation device for determining a degree of wear of the change component based on the actual parameter and a communication device for communicating information concerning a required replacement of the change component to an external terminal that is communicatively linked to the floor treatment appliance. The change component is a floor treatment element that mechanically acts upon a floor surface to be treated, and the evaluation device calculates an average value of the actual parameter detected by the detection device referred to a defined time period of at least one hour, compares the average value with a defined reference value and determines the degree of wear of the change component in dependence on the result of the comparison.

Disclosed herein is an intelligent robot cleaner. The intelligent robot cleaner primarily senses foreign matter sucked through a suction unit under the control of a control unit, and secondarily senses an article collected in a collection unit, if articles other than the foreign matter are sensed, thus allowing a use to recognize accurate information about the article collected in the collection unit and preventing valuables or small articles from being lost. The intelligent robot device may be associated with an artificial intelligence module, a unmanned aerial vehicle (UAV), a robot, an augmented reality (AR) device, a virtual reality (VR) device, devices related to 5G services, and the like.

A vacuum collection vehicle may include a chassis, a vacuum container supported by the chassis, a vacuum source separated from the vacuum container by an intermediate wall and a filter. The vacuum source is in pneumatic connection with the filter through the intermediate wall. A plurality of discharge conduits extend through the intermediate wall, extend over and above the filter, along the roof of the vacuum container. The plurality of discharge conduits have a plurality of respective outlets at different locations within the interior of the vacuum container for discharging collected material into different collection receptacles. The filter is sandwiched between the intermediate wall and the plurality of discharge conduits.

Provided is a method for controlling a robot cleaner including a first operation of identifying that a manual cleaner and the robot cleaner are turned on, a second operation of identifying, by the robot cleaner, a location of the manual cleaner, a third operation of moving, by the robot cleaner, to a location within a first set distance from the manual cleaner, and a fourth operation of stopping the movement of the robot cleaner when the robot cleaner is located at the location within the first set distance from the manual cleaner while the manual cleaner is moving, and performing, by the robot cleaner, cleaning while moving when the robot cleaner is located at a location within a second set distance from the manual cleaner.

A portable surface cleaning apparatus has a main body and air treatment member assembly is removably mounted to the main body. The air treatment member assembly air outlet and/or the suction motor inlet end is provided at the lower end of the air treatment member assembly when the surface cleaning apparatus is located on a floor and a pre-motor filter underlies the air treatment member assembly and/or the suction motor.

A method of controlling movement of a robotic cleaning device over an area to be cleaned. The method includes acquiring a visual representation of the robotic cleaning device on a display of a wireless communication device, identifying the robotic cleaning device in the visual representation, computing a coordinate transform between the visual representation and a robotic cleaning device coordinate system, creating an instruction by receiving user-indicated spatial information on the display or how the robotic cleaning device should move over the area to be cleaned, applying the transform to the spatial information, transforming the spatial information to the robot coordinate system, and sending the instruction to the robotic cleaning device via wireless communication, to cause the robotic cleaning device to move over said area in accordance with the transformed spatial information.

A vacuum cleaner that includes a suction source configured to generate a suction airflow, a dirt collector in fluid communication with the suction source and configured to separate debris from the suction airflow and the dirt collector is configured to store the debris separated from the suction airflow. The vacuum further includes an infrared sensor operable to output a signal corresponding to a distance to an amount of debris stored in the dirt collector, a controller that receives the signal, and the controller is operable to determine a fill level stored in the dirt collector based on the signal. A visual display displays the fill level stored in the dirt collector.

The invention pertains to a system consisting of a first floor treatment apparatus that is exclusively guided manually within an environment by a user and a second floor treatment apparatus that is exclusively operated automatically, wherein the second floor treatment apparatus is designed for orienting and localizing itself within an environment. The first floor treatment apparatus is designed for detecting a movement path of the first floor treatment apparatus during a movement of the first floor treatment apparatus that is manually guided by a user, as well as for transmitting information on the detected movement path to the second floor treatment apparatus by means of wireless communication. The second floor treatment apparatus is designed for receiving the information and for autonomously traveling along the movement path within the environment based on the received information.
