Cleaning device such as carpet cleaner, floorwasher, floor sweeper, polishing machine and the like with two motors

Abstract

A cleaning device such as a carpet cleaner, floorwasher, floor sweeper, polishing machine with two motors, comprising a wheeled base provided with brushing elements driven by a first electric motor; the wheeled base is maneuvered by a handle that supports a suction body that is pivoted to the base; the suction body is provided with suction elements operated by a second electric motor. The first motor and the second motor are both accommodated in a corresponding seat on the wheeled base.

1 . A cleaning device such as carpet cleaner, floorwasher, floor sweeper, polishing machine with two motors, of the type that comprises a wheeled base provided with brushing means driven by a first electric motor, said wheeled base being maneuvered by means of a handle that supports a suction body that is pivoted to said base, said suction body being provided with suction means that are operated by a second electric motor, wherein said first motor and said second motor are accommodated in a corresponding seat on said wheeled base.  
   
   
       2 . The device of  claim 1 , wherein an axis of said second electric motor coincides with an axis about which said suction body, and therefore said handle rigidly coupled to the suction body, are pivoted to said wheeled base.  
   
   
       3 . The device of  claim 2 , wherein said first electric motor and said second electric motor are arranged so that their axes are parallel.  
   
   
       4 . The device of  claim 2 , wherein said first electric motor and said second electric motor are arranged so that their axes are perpendicular.  
   
   
       5 . The device of  claim 1 , wherein said sweeping means are formed by at least one roller for treating a surface, said roller being turned by said first motor by means of a belt device.  
   
   
       6 . The device of  claim 1 , wherein said sweeping means are formed by at least one circular brush, whose axis is perpendicular to the floor, said at least one brush being driven by said first motor by means of a direct coupling.  
   
   
       7 . The device of  claim 1 , wherein said suction means comprise a hose for conveying aspirated dust toward a dust collection bag with at least one filtering device, and a suction impeller associated with said second electric motor.  
   
   
       8 . The device of  claim 1 , wherein said suction means comprise a hose for conveying aspirated liquids toward a liquid collection tank.  
   
   
       9 . The device of  claim 5 , wherein said roller is provided with bristles.  
   
   
       10 . The device of  claim 5 , wherein said roller is cylindrical and adapted for polishing a floor.  
   
   
       11 . The device of  claim 6 , wherein said at least one circular brush has an abrasive polishing surface.  
   
   
       12 . The device of  claim 1 , wherein said first motor is accommodated in a first seat and said second motor is accommodated in a second seat.  
   
   
       13 . The device of  claim 1 , wherein said first motor and said second motor are accommodated in a same single seat.
