Wet cleaning device

Abstract

A wet cleaning device (WCD) comprises a mopping unit (MU) for wet cleaning a surface, and an arrangement (ST) for increasing a pressure of the mopping unit (MU) to the surface by means of suction. The arrangement includes a hose at a side of the mopping unit (MU), the hose having an opening for applying suction to the surface. The hose may be present at opposite sides of the mopping unit (MU). Alternatively, the hose may be present around the mopping unit (MU). Preferably, a suction power of the arrangement is controllable. Advantageously, the suction power is controllable in dependence on a detection of stains, a speed of the wet cleaning device (WCD), and/or a type of the surface. If the wet cleaning device (WCD) is formed by a mopping robot vacuum cleaner, the suction for the arrangement (ST) is advantageously a part of a suction generated for vacuum cleaning.

1 . A wet cleaning device, comprising:
 a mopping unit for wet cleaning a surface, and   an arrangement for increasing a pressure of the mopping unit to the surface by means of suction, wherein the arrangement includes a hose at a side of the mopping unit, the hose having an opening for applying suction to the surface.   
     
     
         2 . The wet cleaning device as claimed in  claim 1 , wherein the hose is present at opposite sides of the mopping unit. 
     
     
         3 . The wet cleaning device as claimed in  claim 1 , wherein the hose is present around the mopping unit. 
     
     
         4 . The wet cleaning device as claimed in  claim 1 , wherein a suction power of the arrangement is controllable. 
     
     
         5 . The wet cleaning device as claimed in  claim 4 , wherein the suction power is controllable in dependence on a detection of stains. 
     
     
         6 . The wet cleaning device as claimed in  claim 4 , wherein the suction power is controllable in dependence on a speed of the wet cleaning device. 
     
     
         7 . The wet cleaning device as claimed in  claim 4 , wherein the suction power is controllable in dependence on a type of the surface. 
     
     
         8 . The wet cleaning device as claimed in  claim 1 , wherein the wet cleaning device is formed by a mopping robot vacuum cleaner, the suction for the arrangement being a part of a suction generated for vacuum cleaning.
