The present invention relates to a cleaning device for cleaning a surface (20), comprising: —a brush (12) rotatable about a brush axis (14), said brush (12) being provided with flexible brush elements (16) that are substantially uniformly distributed over the periphery of the brush (12), wherein the brush (12) is at least partly surrounded by a nozzle housing (28) and protrudes at least partially from a bottom side (30) of said nozzle housing (28), which, during use of the device (100), faces the surface to be cleaned (20), wherein the brush elements (16), during the rotation of the brush (12), substantially form a sealing with the housing (28) at a first position (33) where the brush elements (16) leave the housing (28) during the rotation of the brush (12), and contact the surface to be cleaned (20) during the rotation of the brush (12) at a second position (35) for picking up dirt particles (22) and liquid (24) from said surface (20), thereby defining a suction area (34) in a space between the brush (12), said housing (28) and said surface to be cleaned (20) which is at least partly sealed at said first and second positions (33, 35), —a single squeegee element (32) which is spaced apart from the brush (12) and attached to the bottom side (30) of the nozzle housing (28) on a side of the brush (12), where the brush elements (16) enter the housing (28) during the rotation of the brush (12), wherein said squeegee element (32) is adapted for pushing or wiping dirt particles and liquid across or off the surface to be cleaned (20) during movement of the cleaning device (100), thereby defining a suction inlet (36) between the squeegee element (32) and the brush (12)that opens into the suction area (34), —a drive means for driving the brush (12) in rotation, and —a vacuum aggregate (38)which is arranged at a suction outlet (47)of the suction area (34) for generating an under-pressure in said suction area (34) for ingesting dirt particles (22) and liquid (24) from the suction inlet (36). |

1. A cleaning device for cleaning dirt particles and liquid from a surface, said cleaning device comprising:
a brush rotatably mounted in a nozzle housing for rotation about an axis and comprising a multiplicity of radially-extending flexible brush elements uniformly distributed over a circumferential periphery of the brush, said nozzle housing at least partly surrounding the brush and including an opening at a bottom side that, during use of the cleaning device, faces the surface to be cleaned, said opening being defined by first and second axially extending end portions nozzle housing arranged such that, during rotation of the brush: the first axially-extending and portion is located sufficiently close to ends of the brush elements leaving the nozzle to continuously form a seal therewith, but access of said brush elements to the dirt particles and liquid on said surface to be cleaned being unobstructed when the nozzle is moved in a direction in which the second axially-extending end follows the first axially-extending end; and the second axially-extending end portion is spaced apart from brush elements re-entering the nozzle housing after contacting the surface to be cleaned, said spacing of the second axially-extending end portion from the re-entering brush elements defining a suction area for vacuuming the dirt particles and liquid from the surface to be cleaned; a single wiper strip attached along the second axially-extending end portion of the nozzle housing and extending to the surface to be cleaned, said wiper strip being adapted to move dirt particles and liquid along the surface to be cleaned during movement of the cleaning device and defining, in a region between the single wiper strip and the brush elements, a suction inlet in communication with the suction area; a drive apparatus for rotating the brush; and a vacuum apparatus for coupling to a suction outlet in communication with the suction area for generating an under-pressure in said suction area. |
