A cleaner head for a cleaning appliance including an agitator rotatable about an axis; a housing having a front side, a rear side, and first and second sides which extend between the front side and rear side, said housing further including a floor facing surface. The housing defines a chamber which at least partially surrounds the agitator, the chamber having a dirty air inlet and a dirty air outlet. A wiper device which extends laterally between the first and second sides of the housing and is positioned on or adjacent the floor facing surface. A floor engaging device extends laterally between the first and second sides of the housing and is positioned on or adjacent the floor facing surface. The floor engaging device includes an absorbent portion. The wiper device and the floor engaging device are positioned rearwardly of the dirty air inlet.

A surface cleaning machine includes: a suction device; a cleaning base suitable for moving on a surface to be cleaned, the cleaning base comprising a cleaning roller capable of rotating; a cleaning liquid supply unit; and a dirty liquid recovery tank, the dirty liquid recovery tank being in fluid communication with the suction device; where the cleaning base further includes a transfer chamber adjacent to the rear side of the cleaning roller and capable of temporarily holding a solid-liquid mixture, the transfer chamber configured to be in fluid communication with the suction device, so that the surface cleaning machine can transfer at least a part of liquid or at least a part of a solid-liquid mixture from the transfer chamber to the dirty liquid recovery tank by means of the suction device, thereby achieving a low energy consumption operation.

A mobile cleaner includes a body, a mop module, and a sweep module. The mop module includes a pair of spin mops configured to rotate and mop a surface. The sweep module is configured to sweep up foreign material on the surface using a rotating agitator. The sweep module includes a dust housing, the agitator, and a wheel assembly. The wheel assembly is configured to support the dust housing on the surface and includes a wheel body that is movable in a vertical direction. A cliff sensor is configured to detect movement of the wheel body.

A cleaning robot includes a housing and a roller brush. The housing is provided with a mounting cavity with an opening at its bottom. The roller brush is rotatably arranged in the mounting cavity and at least part of the roller brush is extended out of the mounting cavity. At least part of the cavity wall is transparent to form a transparent area, and a viewing area is set at a position of the housing and above the transparent area. The closed observation space is formed in the housing, and the observation space communicated with the viewing area and the transparent area, so that the user can observe the working condition of the roller brush inside the mounting cavity.

The cleaning robot includes a housing, a brush roller and a suction device. The housing is provided with a mounting chamber. A debris collecting chamber is communicated with the mounting chamber. The brush roller is pivotally mounted in the mounting chamber and at least a part of the brush roller protrudes from the mounting chamber. The housing is further provided with a debris collecting channel, one end of the debris collecting channel is communicated with the debris collecting chamber, the other end of the debris collecting channel penetrates through the rear end of housing, and the housing is further provided with a first door for opening or closing the debris collecting channel.

A cleaner includes a body including an insertion slot facing a floor and an installation space inside the body. The cleaner includes a dust housing detachably connected to the body. The dust housing includes a collection opening surface and a storage space that stores foreign substances collected through the collection opening surface. The cleaner has an agitator rotatably connected to the dust housing and exposed through the collection opening surface. The cleaner also includes a driving apparatus that rotates a driving coupler, which drives a driven coupler coupled to the agitator. The cleaner includes a lever located on either the driving coupler or the driven coupler. The lever selectively attaches or separates the driving coupler and the driven coupler. Manipulating the lever separates the driving coupler and the driven coupler and allows the sweep module including the agitator to be removed through the insertion slot in the body.

A surface cleaning apparatus is provided with a fluid delivery system for delivering a cleaning fluid to the surface to be cleaned. The fluid delivery system includes one or more fluid supply tanks for storing a supply of cleaning fluid, a fluid distributor for applying the cleaning fluid to the surface to be cleaned, and a fluid supply conduit for delivering the cleaning fluid from the fluid supply tank to the fluid distributor.

A cleaner head including: a brushbar arrangement including a first elongate portion, and a first curved portion located at a first end of the first elongate portion. The brushbar arrangement at least partially extends around a suction region. The cleaner head further includes a drive assembly configured to rotate the first curved portion and the first elongate portion.

A surface cleaning machine is provided, including a cleaning head having at least one driven cleaning roller unit, a dirty fluid reservoir device arranged on the cleaning head, and a scraping guide device for dirty fluid that acts on the at least one cleaning roller unit, wherein the dirty fluid reservoir device has a container device for dirty fluid and a cover device for the container device, wherein a duct device for cleaning liquid is arranged on the cover device, and wherein there is arranged on the cover device an orifice device which is fluidically connected to the duct device and by means of which cleaning liquid is applicable to the at least one cleaning roller unit.

The invention relates to a floor cleaning machine, including a floor head, at least one cleaning roller, which is arranged on the floor head, a tank device, which is arranged on the floor head, and at least one sweeping element, which is associated with the at least one cleaning roller. To provide a floor cleaning machine of that kind, which has an optimized coarse dirt pickup function, the at least one sweeping element is arranged on the tank device and that at least a partial region of the tank device on which the at least one sweeping element is arranged is movable relative to the floor head in a cleaning operation.
