A method of controlling a moving robot is provided. The method of controlling a moving robot includes the steps of: (a) performing a basic motion of the moving robot which moves on a rotating mop; (b) measuring the slip rate of the moving robot; and (c) controlling the travel of the moving robot.

A floor cleaning and polishing device has a polishing pad for a surface which is rotationally engaged upon a pad driver operatively engaged to a frame. A first set of wheels on the frame allow for tilted movement. A second set of wheels are positionable to a deployed position to elevate the first set of wheels from the surface and position the polishing pad parallel to the surface. The device may have a light projector engageable for light disinfecting. The polishing pads are configured with a plurality of polishing fabric sections separated by recesses therebetween.

A turntable structure includes a cleaning turntable having one side connected with a cleaning piece; an adjusting component slidably connected with the cleaning turntable along a target direction, and located on another side of the cleaning turntable opposite to the cleaning piece, the adjusting component having a side far away from the cleaning turntable and connected with a driving mechanism of a robot to rotate the cleaning turntable, the target direction being parallel to a rotating shaft of the cleaning turntable; a pressure unit provided between the cleaning turntable and the adjusting component and for pressing against the cleaning turntable; and a first limiting structure configured to limit a sliding distance of the cleaning turntable relative to the adjusting component along the target direction.

A handheld cleaning device includes a surface-moving portion and an upright portion. The surface-moving portion is in contact with a surface to be cleaned and is connected with the upright portion. The upright portion is configured to move the surface-moving portion in a case in which the surface-moving portion is in operation. The handheld cleaning device further includes a power battery configured to supply power to the handheld cleaning device. The surface-moving portion further includes at least two non-coaxial brushrolls configured to clean stains on the surface to be cleaned. The rotation speed of each brushroll is less than 3000 r/min.

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.

A cleaning assembly for a cleaning robot is provided. The cleaning assembly includes a motor, a transmission mechanism coupled with the motor, and a cleaning device comprising a shaft having a first gear coupled with the transmission mechanism and a cleaning module mounted to an end of the shaft. The transmission mechanism is configured to drive the shaft to rotate through the first gear. The shaft is configured to move axially. The cleaning module is configured to clean a surface area.

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.

Roller brushes for a cleaning and/or care devices, for example, for cleaning and/or care of floor coverings in the form of tiles, natural, artificial, blocks of concrete or wood, with a rotationally symmetrical cylinder which comprises a cylinder surface. At least one first plurality of a first bundle of bristles with a first brush and a second plurality of a second bundle of bristles with a second brush may be arranged on the cylinder surface. The first bundle of bristles may be different from the second bundle of bristles.

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 nozzle of a cleaner includes a nozzle housing having a first flow path extending in a left-right direction of the nozzle and a second flow path extending in a front-rear direction of the nozzle; first and second rotation cleaning units disposed behind the first flow path and spaced apart from each other in the left-right direction, the second flow path being positioned between the first and second rotation cleaning units, first and second driving motors disposed on opposing sides with respect to a centerline of the second flow path to rotate the first and second rotation cleaning units; mops attached to each of the first and second rotation cleaning units and an axis of the first driving motor and an axis of the second driving motor extend in a non-parallel angle with respect to the centerline of the second flow path.
