Provided is a robot cleaner using an artificial intelligence (AI) algorithm and/or a machine learning algorithm in a 5G environment connected for Internet of Things (IoT). The robot cleaner includes one or more sensors, a driving wheel, a suction blower, and a controller, and the controller defines a cleaning target area, identifies a user's location and a type of the user's behavior, collects life pattern information of the user including the user's location, the type of the user's behavior, and timestamps each associated therewith during the time period of one day or more, determines a cleaning schedule of the robot cleaner based on the collected life pattern information, and controls the driving wheel and the suction blower so as to perform cleaning in accordance with the determined cleaning schedule.

An industrial robotic vacuum system for cleaning agricultural facility ventilation ductwork. The industrial robotic vacuum system generally includes a robotic vacuum head.

In a vacuum cleaner electric blower is driven by power supplied by a secondary battery. A dust-collector is configured to catch and collect dust and dirt sucked by driving the electric blower. A detector is configured to detect a remaining amount of the secondary battery. A controller is configured to control suction force of the electric blower. In the case cleaning is finished when the remaining amount of the secondary battery detected by the detector is equal to or less than a predetermined value, the controller sets the parameter to reduce the suction force of the electric blower for the next cleaning. In the case cleaning is finished when the remaining amount of the secondary battery detected by the detector is not equal to or less than the predetermined value, the controller sets the parameter to increase the suction force of the electric blower for the next cleaning.

An auto clean machine comprising: a chassis; an internal light source, located inside the chassis, for emitting internal light; an external light source, located outside the chassis, for emitting external light; an optical sensor, configured to sense optical data generated according to the external light or according to the internal light; and a control circuit, configured to analyze optical information of the optical data. If the internal light source is activated, the external light source is de-activated and the control circuit determines variation of the optical information is larger than a variation threshold, the control circuit changes the internal light source to be non-activated and the external light source to be activated.
