Embodiments of the disclosure relate to a robot cleaner and a controlling method thereof, and more particularly, to a robot cleaner and a traveling algorithm of a robot cleaner having an improved structure. A robot cleaner of the disclosure includes a brush unit having a suction flow path, a body unit configured to have a driving device, and be coupled to the brush unit to be rotatable with respect to the brush unit and a redirection device configured to rotate the body unit relative to the brush unit, and the redirection device includes a rotation guide extending along an inner circumferential surface of the brush unit, a rotation driving source disposed in the body unit and generating power, and a power transmission member which moves along the rotation guide by the power transmitted from the rotation driving source and rotates the body unit with respect to the brush unit.

A cleaning pad for an autonomous cleaning robot evenly wets and collects debris for cleaning operations. The pad includes a core of absorbent layers for absorbing liquid through capillary action and for distributing the liquid within the cleaning pad. The pad includes a wrap layer around the core, the wrap layer comprising a fibrous layer that is flexible and absorbent, the fibrous layer configured to absorb liquid through capillary action and transfer the liquid to the core. The pad includes one or more transition regions spanning a cleaning width of the cleaning pad, the one or more transition regions dividing the cleaning pad into at least two segments. The forward positioned segment of the pad, of the at least two segments of the pad, has a lesser thickness compared to a thickness of an aft positioned segment of the at least two segments.

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 autonomous cleaning device, includes: a mobile platform, configured to move autonomously on a cleaning surface; and a cleaning module, disposed on the mobile platform and including: a wet cleaning module, configured to clean at least part of the cleaning surface in a wet cleaning mode; and a lifting structure, connected to the wet cleaning module and configured to enable the wet cleaning module to move upward or downward with respect to the mobile platform; wherein the wet cleaning module includes: a cleaning head configured to clean the cleaning surface; and a driving unit configured to drive the cleaning head to conduct reciprocating movement on a target surface which indicates a part of the cleaning surface.

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

The present disclosure relates to a cleaning assembly and a smart cleaning device. The cleaning assembly is capable of being mounted on a machine body of a smart cleaning device and includes a connecting plate and a soft cleaning body, wherein the connecting plate and the soft cleaning body are detachably connected through a slide assembly, the slide assembly includes a mounting groove and a guide bar which are mutually matched, the mounting groove is provided on one of the connecting plate and the soft cleaning body, and the guide bar is disposed on the other one of the connecting plate and the soft cleaning body.

The present disclosure relates to a sealing structure and a smart cleaning device. The sealing structure is configured to seal an infrared wall-following module of the smart cleaning device. The sealing structure includes a housing and a lens. The housing is connected to a side of the infrared wall-following module facing a protective shell of the smart cleaning device. The lens is connected to the housing, and the lens covers a side surface of the housing facing the protective shell. The lens includes an arc-shaped panel and a connecting plate that is arranged on an edge of the arc-shaped panel and that extends toward the infrared wall-following module.

In some examples, a moisture-proof mat is provided for an intelligent cleaning apparatus or an intelligent cleaning system. The intelligent cleaning apparatus is provided with a wet cleaning pad. The intelligent cleaning apparatus can be charged by a charging station. The moisture-proof mat may include an installation unit, configured to install the moisture-proof mat to the charging station. At least a portion of the moisture-proof mat is configured to be located under the wet cleaning pad (4) when the intelligent cleaning apparatus is charged by the charging station. When the intelligent cleaning apparatus is charged by the charging station, at least a portion of the moisture-proof mat is positioned under the intelligent cleaning apparatus.

An extraction head for a cleaning machine is disclosed for traveling along a cleaning path on a variable-height floor. The extraction head comprises a body including a floor-facing surface and an extraction aperture disposed in the floor-facing surface. The extraction head comprises a vacuum outlet in fluid communication with the extraction aperture. The extraction head comprises an adjustable-height brush positioned in front of the extraction head body along the cleaning path. The adjustable-height brush is configured to translocate upwardly and downwardly as the extraction head moves along the cleaning path on the variable-height floor. The adjustable-height brush may comprise a proximal end and a distal end opposite the proximal end. The proximal and distal ends may be configured to translocate upwardly and downwardly relative to each other as the extraction head moves along the cleaning path on the variable-height floor.

A robotic vacuum cleaner is provided having a suction source, a dirt collector, a floor sensor, a primary brush, and an auxiliary brush. The floor sensor includes an emitter and a detector having an intersecting region. The auxiliary brush includes microfiber fingers that are spaced around a perimeter of the brush, or the auxiliary brush includes a pad having apertures, the apertures allow the emitter and detector to sense whether a floor surface is present.
