A liftable and rotatable mop structure and a cleaning machine are provided. The liftable and rotatable mop structure includes a mop unit which includes a mop, a turntable and a rotatable shaft, wherein the mop is connected with the turntable, and the rotatable shaft is connected with the turntable; the rotatable shaft functions to lift the turntable and drive the turntable to rotate, and includes an inner shaft and an outer shaft surrounding the inner shaft; a limiting structure is arranged between the inner shaft and the outer shaft so that the inner shaft and the outer shaft are movable relative to each other in an axial direction but are limited in a circumferential direction.

A mobile cleaner includes a dust housing, an agitator, and a dustpan. The dust housing has a collection opening facing a surface. The agitator is rotatably disposed within the dust housing and is exposed to the surface through the collection opening. The agitator is configured to move foreign material from the floor into the dust housing. The dustpan directs the foreign material moved by the agitator into the dust housing. The dustpan extends around a portion of an outer circumferential surface of the agitator and is configured to rotate independent of the agitator.

An apparatus for cleaning a floor includes a housing, wheels by which the apparatus is adapted to move; a motive device for moving the apparatus, a steering mechanism, and a cleaning assembly including a cleaning unit and an offset mechanism adapted to move the cleaning unit to or from an offset position projecting beyond one lateral side of the apparatus. In another embodiment, an apparatus for cleaning a floor includes a housing, wheels by which the apparatus is adapted to move, a motive device for moving the apparatus, a steering mechanism, and a cleaning assembly including a cleaning unit and a swing mechanism indirectly linking the cleaning unit to the steering mechanism such that when the apparatus is in an operative mode, the cleaning unit reorients its position in synchronization with the path of travel of the apparatus. Optionally, a lifting device may raise and lower the cleaning assembly.

A mobile robot. The mobile robot comprises a robot housing (10), two moving components (40), a container apparatus (20), and a cleaning component (50); the moving components are mounted on the robot housing for moving the mobile robot; the cleaning component comprises a main brush (520) provided laterally relative to a normal forward direction (f) of the mobile robot; the main brush is mounted on the robot housing and at or near a part of the robot housing, at which position a transverse width is largest; extension of the main brush in a direction perpendicular to the normal forward direction of the mobile robot is not interfered with by the moving components. The mobile robot has a larger main brush width, and thus the working width of the mobile robot is increased.

The manually operated floor sweeper is a manually powered cleaning unit that replaces the standard push broom. Designed for indoor and outdoor use, the manually operated floor sweeper provides a plurality of brushes that move dirt and trash to a hopper, which transports the dirt and trash to a receptacle. The manually operated floor sweeper comprises a plurality of brushes, a hopper system, a drive system, a gearing system and a body.

A floor polishing or grinding pad assembly is provided. In one aspect, a polishing or grinding pad assembly employs a flexible pad, a reinforcement layer or ring, and multiple floor-contacting tools such as abrasive disks. In another aspect, the reinforcement layer includes a wavy or undulating internal edge shape. A further aspect includes an inner ring edge having radially extending slots between pairs of radially enlarged tool mounting peaks. Still another aspect includes an insulator or spacer between a head of an abrasive tool and a reinforcement ring.

An automatic cleaning machines comprises a high-speed reciprocating cleaning means making a cleaning cloth reciprocatingly wipe a floor at high speed and a vacuum device sucking the dust in front of the cleaning cloth.

An automatic floor-disinfection robot for floors of hospital rooms, including a moving device, a alarm and a disinfection device. The moving device is a disc-shaped robot, and includes a chassis moving mechanism, a support plate and a top plate arranged successively from bottom to top. The disinfection device includes a disinfection assembly and a baffle. The disinfection assembly includes a liquid supply mechanism, a liquid spray mechanism and a fan.

A side brush for a robotic cleaner. The side brush is rotatable about a rotation axis in a rotational direction and has a brush body and numerous linear bristles including a first bristle having a base end at the brush body and an opposite distal end. An imaginary line extends perpendicularly to the rotation axis. The first bristle extends in a bristle direction outwardly from the brush body. Seen in a top view, the bristle direction extends at a first angle to the imaginary line with the distal end pointing rearwardly in relation to the rotational direction. Seen in a side view, the bristle direction extends at a second acute angle to the rotation axis pointing away from the brush body. A robotic cleaner having such a side brush is also disclosed herein.

An abrasive or cleaning pad includes a composite resin as a wear layer. A cleaning pad system for motorized floor cleaning or polishing applications includes a pad having a combination of two grades of melamine resin-based foam. A method of cleaning a floor surface is also provided.
