The present invention relates to a vacuum cleaner robot comprising a floor nozzle supported on wheels and a dust collection unit, wherein the floor nozzle comprises a driving device for driving at least one of the wheels of the floor nozzle, wherein one of the wheels, a plurality of or all of the wheels of the floor nozzle are omnidirectional wheels, wherein the floor nozzle comprises a base plate with a base surface, which, when the vacuum cleaner robot is in operation, faces the surface to be cleaned, the base plate having provided therein an air flow channel, which extends parallel to the base surface and through which air to be cleaned enters the floor nozzle, and wherein the floor nozzle comprises a rotating means for rotating the air flow channel about an axis perpendicular to the base surface.

A cleaning apparatus may include a cleaning unit that is kept from moving downwardly from a predetermined limit position. The apparatus body includes a positioning member that positions the cleaning unit at the limit position. The cleaning unit includes an intake nozzle that is arranged at a position separated from the surface to be cleaned by a predetermined gap, a cam member that holds the cleaning unit at the limit position, and an operation input unit that changes the limit position to a higher position by moving the cleaning unit upward by operating the cam member.

The present invention relates to a robotic cleaner comprising: a cleaner body which has a plurality of guide holders provided therein and performs self-driving; and a suction nozzle which receives an agitator therein, has guide protrusions longitudinally protruding from both sidewalls thereof toward the plurality of guide holders and received in the plurality of guide holders, respectively, and is up-and-down movably and back-and-forth swingably mounted to the cleaner body, whereby the driving performance and cleaning performance of the cleaner can be improved.

A mobile cleaning robot can include a body, a drive wheel, and a plurality of skids. The drive wheel can be connected to the body and can be engageable with a floor surface of an environment. The drive wheel can be operable to move the mobile cleaning robot about an environment. The skids can be separate skids that can be connected to the body and can be engageable with the floor surface to support, together with the drive wheel, the mobile cleaning robot with respect to the floor surface.

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.

The present invention discloses a portable vacuum cleaner having a rotatable vacuum assembly. The vacuum cleaner comprises a nozzle assembly including a nozzle cavity, a canister assembly pivotally connected to the nozzle assembly, a dust bag mounted to the canister assembly, a dirty air pathway providing fluid communication between the nozzle cavity and the dust bag and a suction generator for generating a vacuum that draws dirt and debris from the nozzle cavity to the dust bag. The nozzle assembly having a nozzle mount rotatably coupled to the canister assembly to spin about a rotation axis and an angled nozzle rigidly extending from the nozzle mount at an acute angle to the rotation axis. The nozzle assembly is adapted to rotate and could move back and forth for effective collection of dirt and debris.

A method for adaptively operating a cleaning robot based on height difference between floors and the cleaning robot are provided, and according to an embodiment of the present disclosure, the cleaning robot that adaptively operates based on the height difference between the floors includes a central controller that controls a height adjuster that controls a height of a floor cleaner based on height information related to a space stored in a map storage and height information sensed by a sensor.

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.

Disclosed is a robot cleaner which adjusts a suction area of air suctioned into a suction port through a shutter and a shutter driving device configured to operate the shutter, so that a flow rate of air is adjusted, thus more effectively suctioning dust in the air by using a fan motor having a fixed capacity.

The present disclosure provides a vacuum cleaner floor brush with a height-adjustable suction inlet. The vacuum cleaner floor brush includes a floor brush main body, a rolling brush, and a rolling brush cover with an arc-shaped cross section; the rolling brush is fixedly mounted on a preset rolling brush chamber on the floor brush main body; the floor brush main body is provided with a suction inlet adjustment plate; an inner wall of the suction inlet adjustment plate is a cambered surface; a lengthwise direction of the suction inlet adjustment plate is parallel to an axial direction of the rolling brush; two opposite ends in a width direction of the suction inlet adjustment plate respectively extend towards the rolling brush cover and a bottom suction inlet of the floor brush main body; and the suction inlet adjustment plate can flip along a circumferential direction of the rolling brush. In the present disclosure, more than two kinds of different rolling brushes can be mounted on the same floor brush for use. When different rolling brushes are used on different floors, the suction inlet adjustment plate can be adjusted up and down to make the height of the suction inlet change, so as to improve the cleanness of the floor brush.
