Abstract

Surface cleaning utensil, comprising a wet cleaning unit (WCU) having a wetting unit (WP) and a brush unit (BU) for brushing a surface wetted by the wetting unit (WP), the brush unit (BP) having a brush (B) having a plurality of brush elements (BE) (e.g. bristles) at an angle of at least 45°, and preferably at least 70°, to a surface to be cleaned, and a driving unit for driving the brush to move in a plane at an angle of at most 45°, and preferably at most 20°, to the surface. Preferably, the brush unit (BU) comprises a plurality of rotating brushes (B) having a rotation axis at an angle of at least 45°, and preferably at least 70°, to the surface to be cleaned, wherein at least 50% of an area defined by a circumference of each brush (B) is provided with brush elements (BE). Preferably, adjacent rushes (B) have opposite rotation directions. Preferably, the brushes (B) comprise gear-shaped elements (G). Preferably, the driving unit is arranged for causing a translational movement of the brush (B) with respect to the surface cleaning utensil. Preferably, the wet cleaning unit further comprises a drying pad (DP), the brush unit (BU) being positioned between the wetting unit (WP) and the drying pad (DP). Preferably, the surface cleaning utensil further comprises an air inlet (N) located before the wet cleaning unit (WCU) in a motion direction of the surface cleaning utensil.

Claims

exact text as granted — not AI-modified
1 . A surface cleaning utensil, comprising a wet cleaning unit having a wetting unit and a brush unit for brushing a surface wetted by the wetting unit, the brush unit having
 a brush having a plurality of brush elements at an angle of at least 45°, and preferably at least 70°, to a surface to be cleaned, and   a driving unit for driving the brush to move in a plane at an angle of at most 45°, and preferably at most 20°, to the surface, wherein the wet cleaning unit further comprises a drying pad, the brush unit being positioned between the wetting unit and the drying pad.   
     
     
         2 . The surface cleaning utensil as claimed in  claim 1 , wherein the brush unit comprises a plurality of rotating brushes having a rotation axis at an angle of at least 45°, and preferably at least 70°, to the surface to be cleaned, wherein at least 50% of an area defined by a circumference of each brush is provided with brush elements. 
     
     
         3 . The surface cleaning utensil as claimed in  claim 2 , wherein adjacent brushes have opposite rotation directions. 
     
     
         4 . The surface cleaning utensil as claimed in  claim 3 , wherein the brushes comprise gear-shaped elements. 
     
     
         5 . The surface cleaning utensil as claimed in  claim 1 , wherein the driving unit is arranged for causing a translational movement of the brush with respect to the surface cleaning utensil. 
     
     
         6 . The surface cleaning utensil as claimed in  claim 1 , further comprising an air inlet located before the wet cleaning unit in a motion direction of the surface cleaning utensil. 
     
     
         7 . A vacuum cleaner, comprising a nozzle formed by a surface cleaning utensil as claimed in  claim 6 , a suction unit for generating an air flow through the air inlet, and a dirt separation unit for separating dirt from the air flow.
