A vacuum-cleaner nozzle has a housing formed with a downwardly open suction mouth on a lower face of the housing and having a front mouth edge and a rear mouth edge. A suction fitting on a rear end of the housing and opening into the housing serves for drawing air in through the mouth. A floor-engaging support rearward of the rear mouth edge is vertically displaceable relative to the housing between upper and lower positions. A spring biases the support into the lower position.

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 vacuum cleaner includes a foot assembly having a suction inlet thereon, a suction source in fluid communication with the suction inlet to produce a working airflow there through, and a dirt container in fluid communication with the suction inlet and suction source. The foot assembly further includes a body defined by a central portion and a pair of extension arms, a rotatable agitator on each extension arm, and a drive assembly configured to counter-rotate the agitators. The counter-rotating agitators are operable to cooperate with the suction source to direct dust and debris towards the suction inlet.

An autonomous cleaning robot includes a main body including a main mounting frame and an outer shell, a drive wheel assembly, a collision mitigation mechanism, a sweeping and vacuum assembly, a cleaning fluid applicator and cleaning roller assembly, a germicidal ultraviolet light disinfection mechanism, the germicidal ultraviolet light disinfection mechanism capable of disinfecting both cleaning fluid and a cleaning surface, and a main controller unit. The robot uses germicidal ultraviolet radiation to both disinfect a cleaning surface as well as to disinfect used and/or recycled cleaning fluid. A method for cleaning a floor involves activating the robot; checking fluid levels; acquiring imagery of the space to be cleaned, dispensing cleaning fluid, recycling recovered and excess cleaning fluid, irradiating used cleaning fluid, irradiating a cleaning surface, moving across a cleaning area, recording a travel path, traveling across areas not previously traveled across, and powering down when finished.

A cleaning robot, a bristle control method and a bristle control device, and a computer storage medium are provided. The cleaning robot includes a robot body, an side brush assembly disposed on the robot body, and a controller disposed on the robot body and configured to control a target bristle of the side brush assembly to be limited in a designated area. In embodiments of this application, the target bristle of the side brush assembly is limited in the designated area to prevent, as much as possible, the target bristle from exceeding out of the cleaning robot and affecting the appearance of the cleaning robot.

A robotic vacuum cleaner having a nozzle inlet arranged in a portion of a housing of the vacuum cleaner. The nozzle inlet has a frame structure forming an opening. The frame structure has a base portion extending substantially in parallel with a surface to be cleaned, the base portion extending at a first level. A leading edge portion has at least two distance members forming there between a channel to the opening. The channel has a delimiting surface extending at a second level substantially in parallel with the first level. The first level is arranged closer to the surface to be cleaned than the second level. Each distance member has a substantially triangular cross section. At least a portion of side surfaces of the distance members extend substantially perpendicularly to the base portion.

A robotic vacuum (1) includes a main body (2) having a suction port (15) in a bottom surface (2B) thereof; a storage unit (6) housed in the main body and configured to store dust and debris suctioned in via the suction port (15); and at least one wheel (9) that supports the main body (2). The main body (2) has a width Wb in a first direction that is parallel to a rotational axis (AX) of the wheel (9), the storage unit (6) has a width Ws in the first direction, the main body (2) has a height Hb in a second direction that is perpendicular to the rotational axis (AX) and perpendicular to the first direction, and the storage unit (6) has a height Hs in the second direction. The width Wb is 470-600 mm, and the condition 0.5WbWs0.7Wb is satisfied.

A floor cleaner can include a housing adapted for movement over a surface to be cleaned and at least one edge cleaning brush provided on the housing. The edge cleaning brush includes multiple cleaning implements which rotate on different axes. A gear system, such as a planetary gear system, can drive one cleaning implement at a lower speed than another cleaning implement.

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 sweeping assembly for a cleaning device, includes: a brush holder defining an accommodating cavity therein; a main brushroll accommodated in the accommodating cavity of the brush holder, the main brushroll including a cleaning part located at a middle portion of the main brushroll and a connecting part located at an end of the main brushroll, the connecting part being connected to the brush holder or a driver of the cleaning device; and an anti-winding structure arranged at the brush holder, and including a first end connected to the brush holder, and a second end abutting against the brushroll.
