A cleaning accessory for a vacuum cleaner comprises a housing. A rotatable cleaning brush is rotatably mounted to the housing. The rotatable cleaning brush has at least one flexible cleaning element projecting outwards from a side of the housing. The at least one flexible cleaning element is configured to rotate and engage with a surface to be cleaned. A dirt deflector projects from the side of the housing and is configured to surround at least part of the perimeter of the rotatable cleaning brush.

A surface cleaning head with a leading roller may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The surface cleaning head may have dual agitators—a leading roller and a rotating brush roll—with the leading roller being located in front of the brush roll. The leading roller may have a smaller diameter than the brush roll and may provide a softer cleaning element. The leading roller may also have a bottom portion exposed to the flow path to the suction conduit and at least a top half that is not exposed to that flow path. The leading roller may also float relative to the surface cleaning head and/or may be adjustable relative to the brush roll.

A removable rotatable driven agitator is used in a surface cleaning head and is driven by a drive mechanism that axially engages a driven end of the agitator. The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. The removable rotatable agitator may have an end cap mounted on a rotatable bushing at a non-driven end and may have a splined driven member at the driven end to engage a splined drive member on the drive mechanism.

The present disclosure provides a cleaning brush and an intelligent cleaning device. The cleaning brush includes a shaft rod, a cylindrical member and at least one end member. The shaft rod is provided with two first ends which are opposite in an axial direction; the cylindrical member coaxially sleeves the shaft rod and is provided with two second ends which are opposite in an axial direction, and a brush piece is arranged on an outer surface of the cylindrical member; the at least one end member is installed on at least one of the first ends, and the end member is provided with a blocking structure for preventing an entanglement from excessively extending away from the cleaning brush; the end member and the first end are provided with installation structures respectively matching each other; and the second end of the cylindrical member, which corresponds to the end member, covers at least a portion of the end member.

A removable rotatable driven agitator is used in a surface cleaning head and is driven by a drive mechanism that axially engages a driven end of the agitator. The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. The removable rotatable agitator may have an end cap mounted on a rotatable bushing at a non-driven end and may have a splined driven member at the driven end to engage a splined drive member on the drive mechanism.

A cleaning head (100, 200) comprising: a suction interface; a suction network connected to the suction interface, the suction network comprising a waste collection port and a waste container (150, 250) interconnecting the suction interface and the waste collection port; a suction compartment in fluid communication with the waste collection port, the suction compartment comprising an elongate entry aperture; a roller cleaner (120, 220) mounted inside the suction compartment, the roller cleaner (120, 220) having an elongate outer surface portion protruding through the elongate entry aperture; a machine compartment (260) inside which a drive mechanism (266) and electronic circuitry (262) are mounted; a storage portion comprising a cleaning liquid container (140, 240) and the waste container (150, 250) mounted on a storage receptacle (118); a cleaning liquid applicator configured to draw cleaning liquid from the cleaning liquid container (140, 240) and to apply the cleaning liquid to the roller cleaner (120, 220), and a waste remover configured to physically interact with the roller cleaner (120, 220) to remove waste therefrom.

A mopping mechanism is provided. The mopping mechanism includes at least one mopping plate movably mountable to a bottom surface of a cleaning device. The mopping mechanism also includes a magnetic element assembly including a primary magnetic element and a secondary magnetic element, and configured to generate a variable magnetic field to drive the at least one mopping plate to move reciprocatively relative to the bottom surface.

A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.

Provided is a robot, including: a main brush; a peripheral brush; a first actuator; a first sensor; one or more processors; and memory storing instructions that when executed by at least some of the one or more processors effectuate operations including: determining a first location of the robot; obtaining first data indicative of an environmental characteristic of the first location; adjusting a first operational parameter of the first actuator based on the sensed first data; and forming or updating a debris map of the working environment based on data output by the first sensor or another sensor configured to collect data indicative of an existence of debris on a floor, wherein the debris map at least indicates areas covered by the robot and with a high level of debris accumulation; and an application of a communication device paired with the robot and configured to at least display the debris map.

Surface cleaning utensil, comprising a wet cleaning unit (WCU) having a wetting unit (WP) and a brush unit (BU) for brushing a surface wetted by the wetting unit (WP), the brush unit (BP) having a brush (B) having a plurality of brush elements (BE) (e.g. bristles) at an angle of at least 45°, and preferably at least 70°, to a surface to be cleaned, and a driving unit for driving the brush to move in a plane at an angle of at most 45°, and preferably at most 20°, to the surface. Preferably, the brush unit (BU) comprises a plurality of rotating brushes (B) having a rotation axis at an angle of at least 45°, and preferably at least 70°, to the surface to be cleaned, wherein at least 50% of an area defined by a circumference of each brush (B) is provided with brush elements (BE). Preferably, adjacent rushes (B) have opposite rotation directions. Preferably, the brushes (B) comprise gear-shaped elements (G). Preferably, the driving unit is arranged for causing a translational movement of the brush (B) with respect to the surface cleaning utensil.
