 on an innermost side, directed toward said second support, has a smooth flat surface;   on an outermost side, directed toward a rear portion of said scrubber-dryer, has a plurality of first channels along a perimetric profile thereof, which allow passage of water and small debris, said first channels extending in a portion of said second accessory floor wiper directed toward the floor and along a direction substantially at right angles to the floor.   
     
     
         6 . The scrubber-dryer according to  claim 4 , wherein said at least one floor wiper extends longitudinally along a third axis parallel to said first axis and to said second axis and is arranged at a forward end of said front portion with respect to the advancement direction of said scrubber-dryer in the configuration for use, said forward end being opposite from said rearward end with respect to the front portion. 
     
     
         7 . The scrubber-dryer according to  claim 6 , wherein said at least one floor wiper comprises, at an upper portion thereof, a rigid element, H-shaped for detachable association thereof with the body shell, co-molded with a soft element, said rigid element and said soft element extending longitudinally along said third axis and said soft element having a flat surface on a rear side and a roundness on a front side, to act as a bumper. 
     
     
         8 . The scrubber-dryer according to  claim 7 , wherein said at least one floor wiper comprises a lower portion which is contiguous with said upper portion and is designed to come into contact with said floor, said lower portion having a plurality of second channels at said front side which extend longitudinally along an axis substantially at right angles to said floor and having a surface that is smooth and substantially sharp-edged at said rear side. 
     
     
         9 . The scrubber-dryer according to  claim 2 , wherein said plurality of bristles is made of polyamide, polypropylene, microfiber and/or of abrasive material. 
     
     
         10 . The scrubber-dryer according to  claim 1 , wherein said at least one floor wiper is made of elastomeric material. 
     
     
         11 . The scrubber-dryer according to  claim 6 , further comprising at least one electric motor, kinematically connected to said at least one cleaning roller by means of at least one kinematic transmission chain comprising:
 a first sprocket defined at one end of the transmission shaft of said electric motor protruding therefrom and having an axis of rotation coinciding with a fourth axis substantially parallel to said first axis, to said second axis and to said third axis,   a first pulley, keyed on an intermediate shaft oriented along a fifth axis substantially parallel to and interposed between said fourth axis and said first axis, comprising a first crown gear and a second sprocket,   a second pulley, comprising a second crown gear, keyed on said body of said at least one roller,   said transmission chain also comprising a first belt partially mounted on said first sprocket and on said first crown gear and a second belt partially mounted on said second sprocket and on said second crown gear.   
     
     
         12 . The scrubber-dryer according to  claim 5 , wherein said wheels are arranged in a portion of said scrubber-dryer that is directed toward said floor and are in contact with the floor, at least one first wheel of said wheels being partially enclosed by a fairing shaped like a half-shell and extending at said rear portion of said scrubber-dryer, opposite from said front portion with respect to the advancement direction of said scrubber-dryer in the configuration for use.
