Cleaning unit with base station and process for treating floors

Abstract

A unit for treating floors has a motor-driven mobile device and a base station for replenishing the mobile device. The base station has an additional motor-driven transporting device for moving the mobile device into and out of the base station. A process for treating floors with the unit is also provided.

1 . A unit for treating floors, the unit comprising: 
 a motor-driven mobile device; and    a base station for replenishing said mobile device, said base station having a motor-driven transporting device for transporting said mobile device into said base station for replenishing said mobile device and for transporting said mobile device out of said base station.    
   
   
       2 . The unit according to  claim 1 , wherein said mobile device has a wiping cloth to be replenished, cleaned or exchanged.  
   
   
       3 . The unit according to  claim 1 , wherein said mobile device has a storage battery to be charged.  
   
   
       4 . The unit according to  claim 1 , wherein said base station has an oblique plane, and said transporting device transports said mobile device onto said oblique plane.  
   
   
       5 . The unit according to  claim 1 , wherein said transporting device of said base station has at least one lever for gripping said mobile device to transport said mobile device into and out of said base station.  
   
   
       6 . The unit according to  claim 5 , which further comprises a pick-up cooperating with said lever to raise said mobile device being transported in and to then release said mobile device, for guiding said mobile device with further transport into said base station.  
   
   
       7 . The unit according to  claim 2 , wherein said base station has a squeezing roller, and said base station guides said mobile device over said squeezing roller to wring out said wiping cloth.  
   
   
       8 . The unit according to  claim 7 , wherein said base station wets said mobile device before and/or after wringing out by spraying with cleaning fluid.  
   
   
       9 . The unit according to  claim 8 , wherein said base station has a filter for the cleaning fluid and reuses the cleaning fluid recovered by wringing out said wiping cloth after cleaning by said filter.  
   
   
       10 . The unit according to  claim 2 , wherein said mobile device has an adhesive closure disposed thereon, and said base station exchanges said wiping cloth by taking said wiping cloth off said adhesive closure and applying a new wiping cloth to said adhesive closure.  
   
   
       11 . The unit according to  claim 1 , wherein said mobile device has a wiping surface for wiping floors over a web width covered by said wiping surface, a drive unit moves said mobile device, and said drive unit lies inside said web width during movement of said mobile device by said drive unit.  
   
   
       12 . The unit according to  claim 1 , wherein: 
 said mobile device has a base and a drive unit with a motor-driven inertial mass movable relative to said base;    said drive unit drives said mobile device by executing movements of said inertial mass relative to said base;    said drive unit overcomes static friction holding said mobile device on the floor by mass inertia of said inertial mass in a part of said movements of said inertial mass, and said drive unit does not overcome static friction holding said mobile device on the floor in another part of said movements of said inertial mass; and    said movements of said inertial mass relative to said base are altogether iterative.    
   
   
       13 . A process for treating floors with a unit, which comprises the following steps: 
 transporting said mobile device according to  claim 1  into said base station with said motor-driven transporting device of said base station, for replenishing said mobile device; and    transporting said mobile device out of said base station with said motor-driven transporting device of said base station.
