A robotic cleaner may include a chassis, an agitator assembly configured to engage a surface to be cleaned, and a lift mechanism moveably coupling the agitator assembly to the chassis. The lift mechanism may include a biasing mechanism. The biasing mechanism may be configured to generate a biasing force that urges the agitator assembly in a direction away from the surface to be cleaned. The biasing force may be insufficient to lift the agitator assembly from the surface to be cleaned.

A floor cleaning tool including a housing, a reservoir coupled to the housing and adapted to hold a cleaning solution, and a floor-engaging roller coupled to the housing and rotatable with respect to the housing. The tool also includes a wheel by which the floor cleaning tool moves across a floor surface in a direction of travel at least partially defining a front, rear, and lateral sides of the floor cleaning tool. The tool further includes a squeegee laterally insertable between the roller and the wheel, and a squeegee mount located between the roller and the wheel by which the squeegee is releasably mounted to the floor cleaning tool by first and second laterally opposed protrusions rotatably secured within first and second apertures at opposite ends of the squeegee.

The present invention provides a cleaner including a cleaner main body having a controller, a support member detachably coupled to a module mounting portion of the cleaner main body, and a mop module rotatably supported on the support member, wherein the mop module includes a rotating rod configured to be rotatable in at least one direction by being interlocked with a rotation driving portion provided in the module mounting portion when the supporting member is mounted on the module mounting portion, and a mop member formed to surround an outer circumference of the rotating rod so as to mop the floor in response to the rotation of the rotating rod.

A cleaning head for a floor cleaner including a brushroll assembly configured to clean a surface to be cleaned and reduce brushroll maintenance, such as removing hair and debris wrapped around the brushroll assembly and removing debris from a bearing of the brushroll assembly. The brushroll assembly may comprise agitator members to assist in cleaning and maintenance.

A vacuum cleaner includes a main body and a suction nozzle that suctions up dust on the floor. The suction nozzle includes a housing, a driver, and a rotating brush. The housing includes an entrance through which the dust travels to the main body, a first shaft member, and a first rib disposed along a circumference of the first shaft member. The rotating brush includes a cylindrical body rotated by the first shaft member. The rotating brush also includes a brush member attached to an outer surface of the cylindrical body. The brush member rubs against the floor to direct the dust on the floor towards the entrance. As the brush member rotates, it also comes into contact with the first rib. The brush member includes a plurality of filaments. Some of the filaments are elastically deformed in the direction of the rotation axis upon contacting the first rib.

A vacuum cleaner of the present disclosure includes a cleaner body having a suction motor provided inside thereof and a handle provided outside thereof, and a suction nozzle connected to the cleaner body, wherein the suction nozzle includes a housing having at least part of a front portion opened, and a rotary cleaning unit disposed inside the housing, having at least part thereof exposed through the opening of the housing, and configured to clean a floor by a rotating operation, wherein the rotary cleaning unit includes a cylindrical nozzle body rotatably installed inside the housing, and fiber filaments and metal filaments disposed on an outer circumferential surface of the nozzle body.

A cleaner includes a case having an opening formed in a lower side. The cleaner also includes a brush assembly disposed inside the case. The brush assembly includes a horizontally disposed brush bar and a brush coupled to the brush bar. The cleaner includes a suction port for suctioning dust collected by the brush assembly. The cleaner also includes a motor that provides power to the brush assembly. Further, the cleaner includes an operation assembly, connecting the motor and the brush assembly, and converting a rotational movement of the motor into a translational motion of the brush assembly. The operation assembly includes a rotating member coupled to a shaft of the motor, a link connected to the rotating member, a connecting member connecting the brush bar and the link, and a guide rail for guiding the connecting member in a longitudinal direction.

Disclosed is a vacuum cleaner having a structure for preventing foreign matter from entering between a drum brush and a bearing. A vacuum cleaner includes a suction portion formed with a suction port through which air and foreign matter are sucked. The suction portion includes a housing and a drum brush rotatably provided in the housing. The drum brush includes a rotating drum rotating by receiving a driving force and a brush mounted on the rotating drum. The housing is provided with an annular blocking rib, and the brush located at one end of the drum brush is configured to be accommodated in the blocking rib.

A roller assembly for a mobile cleaning system for cleaning a work surface can include a drive shaft, a sheath, a bushing, and a bushing shroud. The drive shaft can be rotatable about a drive axis, and the drive shaft can include a driven end and an opposite bushing end. The sheath can be supported by the drive shaft and the sheath can be rotatable with the drive shaft. The sheath can include a shell engageable with the work surface. The bushing can be located about the bushing end of the drive shaft. The bushing shroud can be connected to the bushing. The sheath and the drive shaft can be together rotatable with respect to the bushing and the bushing shroud, the bushing shroud can include an outer portion defining a first radius of curvature and a recessed portion connected to the outer portion.

The present disclosure relates to a cleaning device and a sweeping assembly thereof. The sweeping assembly includes: a brush holder; a brush body arranged in the brush holder, and including a cleaning part and a connecting part connected to each other, the connecting part being further connected to the driver to rotate the brush body, the cleaning part including a brush member protruding outward therefrom; and an anti-winding structure arranged at the connecting part, and configured to fill up a gap between the brush holder and the connecting part.
