Abstract

The invention relates to a novel wiping device for cleaning surfaces, characterized in that a motor drive is arranged inside a web width covered during wiping movements.

1 - 13 . (canceled)  
     
     
         14 . A device for wiping a flat surface, the device comprising: 
 a wiping surface covering a web width; and    a motor drive for moving the device, said motor drive lying inside said web width during movement of the device by said drive.    
     
     
         15 . The device according to claim  1 , wherein said drive is disposed above said wiping surface.  
     
     
         16 . The device according to claim  1 , which further comprises outer dimensions of the device, said outer dimensions having a ratio of a longest to a shortest side of at least 2:1, in a projection onto the surface to be wiped.  
     
     
         17 . The device according to  claim 16 , wherein said outer dimensions in projection onto the surface to be wiped are restricted by said wiping surface.  
     
     
         18 . The device according to claim  1 , which further comprises a long side of the device, said drive keeping said long side in front during movement of the device by said drive over the surface to be wiped.  
     
     
         19 . The device according to claim  1 , wherein said wiping surface is moved oscillatingly relative to the rest of the device during wiping.  
     
     
         20 . The device according to claim  1 , which further comprises two opposite sides of the device, and wiping cloths each disposed at a respective one of said two opposite sides.  
     
     
         21 . The device according to claim  1 , wherein said wiping surface is continuous.  
     
     
         22 . The device according to claim  1 , which further comprises: 
 a base;    said drive having a motor-driven inertial mass being mobile relative to said base;    said drive moving the device by executing movements of said inertial mass relative to said base;    said drive overcoming static friction holding the device on the surface by mass inertia of said inertial mass in a part of said movements of said inertial mass, and said drive not overcoming static friction holding the device on the surface in another part of said movements of said inertial mass; and    said drive causing said movements of said inertial mass relative to said base to be altogether iterative.    
     
     
         23 . The device according to claim  1 , which further comprises a side of the device facing the surface to be wiped, said wiping surface at least entirely making up said side.  
     
     
         24 . The device according to claim  1 , which further comprises a holding surface for said wiping surface, said holding surface having edges, and said wiping surface projecting laterally opposite said edges.  
     
     
         25 . A unit for treating floors, the unit comprising: 
 a mobile device according to claim  1 ; and    a base station for regenerating said mobile device, said base station having a motor-driven transport device for transporting said mobile device into said base station for regenerating and for transporting said mobile device out of said base station.    
     
     
         26 . A process for wiping a flat surface, which comprises the following steps: 
 providing a device according to claim  1  having said wiping surface covering said web width and said motor drive inside said web width; and    wiping the flat surface with the device.    
     
     
         27 . A process for wiping a flat surface, which comprises the following steps: 
 providing a unit according to  claim 25  having said device with said wiping surface covering said web width and said motor drive inside said web width; and 
 wiping the flat surface with the device.
