A mobile cleaning robot can include a body, a drive wheel, and a plurality of skids. The drive wheel can be connected to the body and can be engageable with a floor surface of an environment. The drive wheel can be operable to move the mobile cleaning robot about an environment. The skids can be separate skids that can be connected to the body and can be engageable with the floor surface to support, together with the drive wheel, the mobile cleaning robot with respect to the floor surface.

A mobile cleaning robot can include a body and a cleaning assembly. The body can include a suction duct. The cleaning assembly can be operable to ingest debris from a surface of an environment. The cleaning assembly can include a dustpan engageable with the surface to direct debris toward the suction duct. The dust pan can be movable with respect to the body.

A mobile cleaning robot can include a body, a drive wheel, and a wheel stop. The drive wheel can be connected to the body and can be operable to move the mobile cleaning robot about an environment. The wheel stop can be movable with respect to the body and the drive wheel between a stop position and a release position. The wheel stop can be engageable with the drive wheel in the stop position to limit vertical travel of the drive wheel with respect to the body.

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.

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.

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.

A method for bringing cleaning robots into and out of a trolley, and cleaning system, in which each cleaning robot is automatically brought into the trolley individually and the cleaning robots are automatically brought out of the trolley in an order depending on the cleaning effort assigned to them or in a sequence specified by a user of the trolley. A cleaning system comprises a trolley and a multiplicity of cleaning robots configured to carry out the method.

A method for emptying cleaning robots and cleaning system, having a dirt collection unit and a suction interface using a trolley, configured to store the plurality of cleaning robots outside their cleaning phase in which they carry out cleaning tasks, and which has a suction system with a foldable suction platform, a suction opening, a dirt container, and a blower. The method includes the steps of unfolding the suction platform of the trolley, if it is folded, so that it is arranged on a substrate on which the trolley stands in an operational set-up position, arranging one of the cleaning robots on the unfolded suction platform, aligning the suction interface to the suction opening, and activating the blower in order to empty the cleaning robot arranged and aligned on the suction platform so that dirt is transported from the dirt collection unit into the dirt container.

Embodiments of the present disclosure provide a cleaning robot and a control method thereof. The cleaning robot includes a chassis; a drive system; an energy storage unit, supported by the chassis and includes at least one charging contact sheet, wherein the charging contact sheet protrudes from a plane of the chassis slightly, and the energy storage unit is configured to be charged according to a predetermined amount in a case that the robot is located at a charging station; and a control system, disposed on a main circuit board inside the cleaning robot and including a non-transitory memory and a processor, wherein the control system is configured to control the energy storage unit to charge according to the predetermined amount based on a to-be-cleaned area and a total power consumption factor.

A cleaning system includes a cleaning vehicle that cleans a predetermined travel route, and a control device. The cleaning vehicle includes a state detection device that detects a state of the travel route, and has a cleaning mode in which the cleaning is performed and a non-cleaning mode in which the cleaning is not performed. The control device executes inspection control for causing the state detection device to detect a state of a pre-set inspection region along the travel route while causing the cleaning vehicle to travel in the non-cleaning mode, specification control for specifying a cleaning required region, where the cleaning needs to be performed in the travel route, based on the state of the inspection region detected in the inspection control, and cleaning control for causing the cleaning vehicle to travel in the cleaning mode in the cleaning required region after the above-mentioned controls end.
