Disclosed herein is an air cleaner disposed in an indoor space. An air cleaner according to an embodiment includes a blowing device including a suction port and a discharge port, a fan motor configured to generate an air flow, a purifying unit installed inside the blowing device to purify air, a driving portion configured to move the air cleaner, a communication unit configured to communicate with a moving agent moving in the indoor space, and a processor configured to receive status information including at least one of air quality information and dust occurrence information collected by the moving agent, determine a specific zone in which air purification is to be performed using the status information collected by the moving agent, and perform air purification in the specific zone.

A mobile robot includes a body and a rotating plate rotatably installed on the body. A mop portion is attached to a lower surface of the rotating plate. And, a rotating ball that is vertically aligned with a rotating shaft of the rotating plate is rotatably installed on the rotating plate.

An autonomous coverage robot includes a cleaning assembly having forward roller and rearward rollers counter-rotating with respect to each other. The rollers are arranged to substantially maintain a cross sectional area between the two rollers yet permitting collapsing therebetween as large debris is passed. Each roller includes a resilient elastomer outer tube and a partially air-occupied inner resilient core configured to bias the outer tube to rebound. The core includes a hub and resilient spokes extending between the inner surface of the outer tube and the hub. The spokes suspend the outer tube to float about the hub and transfer torque from the hub to the outer tube while allowing the outer tube to momentarily deform or move offset from the hub during impact with debris larger than the cross sectional area between the two rollers.

A cleaning robot control method, applicable to a cleaning robot, includes: obtaining a network status of the cleaning robot and performing a preset action when the network status is a network-disconnected state or a network signal intensity is lower than a preset signal intensity threshold. A computer-readable storage medium and a cleaning robot are further provided.

An image selection method, a self-propelled device, and a computer readable storage medium. The method comprises: when travelling, a self-propelled device first performs image acquisition on the surrounding environment by means of an image acquisition apparatus (101); then, when an acquired image contains an identifiable obstacle, the image is given a score according to a scoring rule, the score being for indicating the imaging quality of the identifiable obstacle in the image (102); and finally, after receiving a command requesting to view an image of the identifiable obstacle, the image that contains the identifiable obstacle and that has the highest score is selected as an image to be displayed (103).

An autonomous floor cleaner can include a housing, a drive system for autonomously moving the housing over the surface to be cleaned, and a controller for controlling the operation of the autonomous floor cleaner. The drive system can include at least one drive wheel for driving the housing across a surface to be cleaned. The drive wheel can be selectively moved from an engaged or in-use position to a disengaged or maintenance position. In the disengaged or maintenance position, the wheel is disengaged from the autonomously moveable housing such that it can be pivoted, extended, removed, or otherwise moved farther away from the autonomously moveable housing.

Autonomous carriers or totes that include vacuum units are provided. As the totes move or are moved through a warehouse carrying products, they collect debris. The debris can be analyzed at the tote, and actions can be performed based upon the analysis.

A method of moving a robotic cleaning device through an area includes loading instructions for a plurality of geometric elements. Each geometric element includes a starting point, paths of travel, and waypoints. An ending waypoint of a first geometric element is connected to the starting point for a subsequent geometric element. The instructions for each geometric element do not include dimensions for the one or more paths of travel. The instructions cause the robotic cleaning device to move along a first path of travel of the first geometric element until a sensor of the robotic cleaning device detects that the robotic cleaning device has reached a first waypoint. Then, if the first waypoint is the ending waypoint of the first geometric element, the robotic cleaning device moves along to the subsequent geometric element or changes direction and moves along a second path of travel of the first geometric element.

A mobile disinfection device (200) includes a disinfection chamber (203) coupled to a propulsion system (228) configured for moving along a surface (236) to be disinfected. The disinfection chamber defines a closed distal end (205), an open proximal end (206) and a surrounding wall (207) impervious to the radiation and having opposing front and rear portions and opposing side portions, respective proximal front, rear and side edges of which are propelled by the propulsion system close to the surface to be disinfected. A radiation source (260) is mounted inside the disinfection chamber for irradiating the surface through the open proximal end. The propulsion system includes a peripheral seal (304) surrounding a proximal edge of the wall and configured to obstruct radiation that might otherwise escape from inside the disinfection chamber.

The present disclosure relates to a robotic cleaner. The robotic cleaner may be configured such that an imaginary plane passing mop contact portions having a small area passes through the center of gravity of the robotic cleaner, thereby travelling while the mops effectively scrub a floor surface.
