A method of controlling the robotic floor cleaning machine is disclosed that includes sensing, by a sensor on the robotic cleaning machine, an object within a sensed field. The method further includes determining, by a safety controller on the robotic cleaning machine, whether the object is an immovable object (such as a wall), and deploying an extendable cleaning element to clean the floor surface up next to the wall. The method can further include deploying the extendable cleaning element such that the extendable cleaning element is in contact with and cleans the floor up to an edge of the immovable object. Additionally, the method can include determining that the object is a movable object (such as a living thing) and preventing the extendable cleaning element from extending such that the robotic cleaning machines does not contact the movable object.

A cleaning robot includes a navigator to move a main body, a remote controller to output a modulated infrared ray in accordance with a control command of a user and to form a light spot, a light receiver to receive the infrared ray from the remote controller, and a controller to control the navigator such that the main body tracks the light spot when the modulated infrared ray is received in accordance with the control command. Because the cleaning robot tracks a position indicated by the remote controller, a user may conveniently move the cleaning robot.

A cleaning robot includes a top cover, a bottom cover provided below the top cover, traveling parts provided in the bottom cover, a suction module provided in the bottom cover to suck in foreign materials on the ground, a recessed part firmed to be recessed inward between the top cover and the bottom cover, and a first sensor located in the recessed part.

A cleaning robot includes a top cover, a bottom cover formed below the top cover and configured to move by external force, a fixed body provided in the bottom cover, a first opening formed in an upper portion of the bottom cover and a first sensor connected to the fixed body and externally exposed between the top cover and the bottom cover through the first opening.

A recharge control method includes: providing a robot comprising a body and four infrared carrier receivers, wherein a second and a third of the four infrared carrier receivers are mounted on a front of the body, and a first and a fourth of four infrared carrier receivers are mounted on left side and on a right side of the body; receiving, by one or more of the four infrared carrier receivers, infrared carrier emitted by a charging dock; determining an area where the robot is located, wherein the area is one of at least five areas around the charging dock that are determined based on receiving of the infrared carrier by different combinations of the four infrared carriers and based on not receiving of the infrared carrier by the infrared carriers; and controlling the robot to move to the charging dock according to a movement mode corresponding to the area.

The disclosure belongs to the technical field of intelligent household equipment, and provides to a front bumper assembly and a cleaning robot. The front bumper assembly includes a bumper body and two elastic pieces, the two elastic pieces are disposed at the rear ends of two sides of the bumper body, each of the elastic pieces is of an integrally formed structure and is provided with a first elastic portion and a second elastic portion which are abutted against the bumper body, the first elastic portion is configured for receiving first pressure applied by the bumper body, and is able to apply a first counterforce to the bumper body, the second elastic portion is configured for receiving a second pressure applied by the bumper body, and is able to apply a second counterforce to the bumper body, the first pressure is a pressure in an advancing direction of the cleaning robot, and the second pressure is a lateral pressure perpendicular to or arranged at an acute angle with the advancing direction. The disclosure further provides a cleaning robot. According to the front bumper assembly and the cleaning robot, the number of needed elastic pieces is small, the occupied space is small, and the manufacturing cost is low.

The present disclosure provides a surface cleaning apparatus that includes steam delivery. The apparatus includes a hand-carried body adapted to be hand carried by a user, the hand-carried body having a main housing, a supply tank, and a heater. A flexible hose is mounted to the hand-carried body and a hand-held cleaning tool mounted to an end of the hose. The tool has a liquid distributor to deliver liquid cleaning fluid and a steam distributor to deliver steam. Various features for controlling the operation of electrical component of the extraction cleaner are disclosed.

The present disclosure provides a method for determining a garbage sweeping point in a smart city and an Internet of Things system. The method is implemented by the Internet of Things system. The method includes a user platform, a service platform, a management platform, a sensor network platform, and an object platform. The method is performed through the management platform and includes: obtaining monitoring information on at least one road within a road network area, identifying a target object on the at least one road, the target object including at least garbage to be processed; determining, based on an identification result, information related to the target object, the information related to the target object including at least a garbage volume of the garbage to be processed; and determining at least one target garbage sweeping point based on the information related to the target object.

A method of operating an autonomous cleaning robot includes presenting, on a display of a mobile device, a representation of each of multiple cleaning levels, each cleaning level corresponding to a respective rank overlap parameter for a wet cleaning mission of the autonomous cleaning robot. The method includes receiving, at the mobile device, an input indicative of a selection of one of the cleaning levels; and controlling the autonomous cleaning robot to execute a wet cleaning mission according to the rank overlap parameter corresponding to the selected one of the cleaning levels.
