An optical navigation device comprising: a processing circuit; a first light source, configured to emit first light; a cover; at least one second light source, configured to emit second light toward the cover; and an first optical sensor, configured to sense first optical data generated according to the first light and to sense second optical data generated according to the second light on the cover. The processing circuit determines a dirtiness level of the cover based on the second optical data sensed by the first optical sensor. The optical navigation device can further comprise a second optical sensor. Also, an optical navigation device which can avoid the interference of another optical navigation device is also disclosed.

An autonomous floor cleaner can include a housing, a drive system for autonomously moving the housing over the surface to be cleaned, a controller for controlling the operation of the autonomous floor cleaner, a tank adapted to hold liquid, and a carry handle joined with the tank and/or the housing. The carry handle is movable between different positions, including a position in which the autonomous floor cleaner can be lifted via the carry handle while an inlet and/or outlet of the tank is blocked.

Devices for moving on substantially vertical surfaces, tools for cleaning substantially vertical surfaces and systems for cleaning substantially vertical surfaces are disclosed.

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.

An intelligent cleaning device, comprising a device main body, a camera and a fill-in light, wherein the camera is mounted in the device main body and faces an outer side of the device main body; the fill-in light is mounted in the device main body by means of a fill-in light holder and faces the outer side of the device main body; and an irradiation direction of the fill-in light is the same as a photographic direction of the camera, so as to irradiate at least part of an identification region of the camera.

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.

In a moving robot and a control method according to the present disclosure, an obstacle is detected using structured light irradiated in a predetermined type of light pattern in a traveling direction while traveling, and a specified operation is performed in response to the obstacle. Moreover, a dangerous obstacle is recognized by extracting changes over time using a plurality of images for an obstacle or a low obstacle that is difficult to determine as detected data, and thus, it is possible to improve accuracy according to the determination of the obstacle, improve a corresponding operation according to the obstacle, minimize the uncleaned area while preventing restraint due to the obstacle, and improve the cleaning performance.

An embodiment of the present disclosure provides a cleaning robot and a control method thereof. The cleaning robot includes: a chassis; a fluid applicator, carried on the chassis and configured to distribute a cleaning fluid on at least part of a cleaning width; a fluid storage apparatus, detachably connected to the chassis, wherein the fluid storage apparatus is in communication with the fluid applicator and configured to apply the cleaning fluid distributed by the fluid applicator to a floor; and a control unit, carried on the chassis and configured to control the fluid applicator to stop distributing the cleaning fluid in a case that a to-be-cleaned area of the floor reaches a preset value.

An autonomous cleaning robot includes a controller configured to execute instructions to perform one or more operations. The one or more operations includes operating a drive system to move the cleaning robot in a forward drive direction along a first obstacle surface with a side surface of the cleaning robot facing the first obstacle surface, then operating the drive system to turn the cleaning robot such that the side surface of the cleaning robot faces a second obstacle surface, then operating the drive system to move the cleaning robot in a rearward drive direction along the second obstacle surface, and then operating the drive system to move the cleaning robot in the forward drive direction along the second obstacle surface.

A cleaner includes: a body which forms an outer appearance; and a mop module which is detachably connected to the body. The mop module includes: a pair of spin mops which contacts a floor while rotating clockwise or counterclockwise when viewed from a top; and a module housing which connects the pair of spin mops. The cleaner may travel autonomously due to the rotation of the spin mops.
