A robot cleaner that sweeps dust on the floor toward its center and absorbs the dust through a small-area inlet with a strong suction force, by a cleaning tool that integrates functions of side brushes and a main brush into one. The present disclosure also provides a robot cleaner that enables a large-diameter foreign material to be guided to and effectively absorbed through the inlet without interference by a cleaning tool. The robot cleaner includes a main unit including a fan motor and a dust collector and having an inlet arranged on a base to absorb foreign materials, and a cleaning tool arranged in the bottom of the base, extending to a front side of the base from the inlet and guiding a foreign material on a floor to a side of the inlet, wherein the cleaning tool is arranged to be movable by an external force.

A surface treating apparatus has a first sheet containing unit; a second sheet containing unit; and a sheet driving unit to pull out an elongated sheet from the first sheet containing unit and move it to the second sheet containing unit as the apparatus moves on a surface to be treated. A sheet contacting member contacts one side of the sheet moving from the first sheet containing unit to the second sheet containing unit and brings the other side of the sheet into contact with the surface to be treated when the apparatus moves thereon. The elongated sheet is moved to wipe or apply wax or the like on the surface to be treated as the apparatus moves on the surface while renewing the portion of the sheet to be brought into contact with the surface when desired.

The invention relates to a cleaning device, in particular a floor-cleaning device, comprising a cleaning unit which is at least partly covered by an endless cleaning element that can be rotated continuously in relation to a surface to be cleaned during the action upon a surface to be cleaned. In order to devise a cleaning device in which regeneration of the endless cleaning element is particularly comfortable, the cleaning unit comprises at least one first roller part which can be placed on the surface to be cleaned and a second roller part, the radius of curvature of a roller subsection of the first roller part being different from a radius of curvature of a roller subsection of the second roller part.

An automated floor cleaner (1) has a cleaner body (2); a cleaning means (3, 45, 6) connected to the cleaner body (2) and configured to in use contact a floor surface to clean the surface; a movement means (7, 19, 8) connected to the cleaner body (2) and configured so that in use the floor cleaner (1) can move across a surface, and; a sensing means 16a, 16b configured to sense the position of the floor cleaner within a location and to transmit data relating to the position to a memory module (20) configured to map and record the position of the floor cleaner (1) during use.

The present invention discloses a collecting hair assembly and a collecting hair machine, and relates to the technical field of a cleaning appliance. The collecting hair assembly includes a first barrel, a second barrel, and a controller. A collecting hair component is sleeved at a first connecting part of the first barrel. The free end of the collecting hair component is connected to a second connecting part of the second barrel. The second barrel is provided with a driver. The collecting hair machine includes a housing and the forgoing collecting hair assembly. The housing is provided with a collecting hair operating opening. The first barrel protrudes wholly or partially out of the collecting hair operating opening. Compared with the prior art, the collecting hair assembly and the collecting hair machine can achieve flexible selection of the using section of the collecting hair component by using the controller, without frequent manual replacement of an adhering paper, and with a high degree of intelligentization.
