The present disclosure discloses a robot cleaner, including a cleaner body; and a sensing unit disposed in the cleaner body, wherein the sensing unit includes a rotating body configured to be horizontally rotatable around a rotation shaft passing through an inside of the cleaner body; a sensing unit mounted on one side of the rotating body to sense a feature or an obstacle in the vicinity of the cleaner body; and a tilting unit installed inside the rotating body to vertically tilt the sensing unit.

Example control systems for automated power management of a machine are described herein. In some examples, the control system can be used with a motive machine. The features are described with reference to a hybrid powered sweeper-scrubber machine, but is not limited as such. The machine can include a main machine controller (MMC) operably coupled to an engine, and a power module operably coupled to the MMC by a controller area network (CAN) bus. A sub-system, including a sub-system having motors, can be operably coupled to the power module by the CAN bus. To provide automated power control, the power module can monitor a load of the sub-system, and using the monitored load of the sub-system, the power module can communicate sub-system load information to the MMC. The MMC can automatically adjust an engine speed based on the sub-system load information and the selected functional mode of the machine.

Disclosed are a cleaning roller and a rolling steam mop. The cleaning roller includes a central shaft capable of rotating, a steam channel, and a cleaning layer. The steam channel is provided with a steam inlet and a plurality of first steam outlets; the steam inlet is used for communicating with a steam generation device: the plurality of first steam outlets are distributed in an axial direction of the central shaft. The cleaning layer is provided around the central shaft; and the steam flowing out from the first steam outlets can be diffused outwards through the cleaning layer When in use, the steam generated by the steam generation device enters the steam channel through the steam inlet, and then flows out from the first steam outlets, and is diffused outwards through the cleaning layer, so that the steam can be diffused to an object to be cleaned.

A robot cleaner includes: a cleaner body; a driving unit configured to provide a driving force; a driving pulley connected to the driving unit, and formed to be rotatable by receiving the driving force from the driving unit; first and second driven pulleys disposed at both sides of the driving pulley; and a belt forming a closed loop by entirely enclosing the driving pulley and the first and second driven pulleys, and configured to rotate the first and second driven pulleys when the driving pulley is rotated.

A mobile apparatus, a chassis for the mobile apparatus and an angle change method for the chassis are provided. The chassis includes: a chassis body including a first body and a second body, with each of the first body and the second body including a bottom surface and a support surface arranged opposite to each other; an angle change device, which is respectively connected with the first body and the second body, disposed between the first body and the second body in an arrangement direction of the first body and the second body, and configured to change an angle between the bottom surfaces of the first body and the second body; and a moving device, configured to move the chassis 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.

Disclosed herein are a vacuum cleaner including: a base including a suction opening; a main frame including a dust collecting apparatus configured to remove dust from air sucked through the suction opening; and a wheel assembly including a forward wheel and a reverse wheel, and rotatably coupled with the base, wherein when the main frame slides with respect to the base, any one of the forward wheel and the reverse wheel contacts a floor. Therefore, the vacuum cleaner may understand a user's intention without adding a senor and a control circuit, and travel actively according to the user's intention.

Disclosed is a robot cleaner capable of reducing the material cost thereof by use of fewer motors, and performing wet cleaning while travelling in all directions and rubbing the floor surface, the robot cleaner includes a plurality of motors generating driving forces, a plurality of pad assemblies configured to rotate by receiving a driving force from one of the plurality of motors, and provided in a tilted manner so that a bottom surface of each of the plurality of pad assemblies has an uneven frictional force with respect to a floor surface, and a tilt gear unit configured to simultaneously vary tilting directions of the plurality of pad assemblies by receiving a driving force from another one of the plurality of motors, wherein the robot clean can travel in all directions depending on a tilting direction and a rotational direction of each of the plurality of pad assemblies.

Provided herein is a robot cleaner. The robot cleaner includes a main body, a driving unit provided in the main body and supplying power for traveling of the robot cleaner, first and second rotary members respectively rotating about first and second rotational axes based on power from the driving unit to provide a movement power source for traveling of the robot cleaner and allowing cleaners for wet cleaning to be fixed thereto, a push stick sensing unit sensing whether a push stick for manual cleaning is coupled to the main body of the robot cleaner, and a controller setting a manual cleaning mode, among cleaning modes of the robot cleaner, when coupling of the push stick is sensed.
