Abstract

A cleaning device includes: a main body having a roller apparatus and a suction apparatus, the roller apparatus defining a line of movement of the cleaning device, the suction apparatus opening out into a suction opening which is arranged on a side of the main body facing a floor to be cleaned, the suction opening being bordered by a first wall and a second wall, the first wall and the second wall running transversely to a line of movement. A lip with an elastic design, which when the cleaning device is used as intended lies on the floor to be cleaned, is assigned to the suction opening. When the cleaning device is moving in a first direction of movement along the line of movement, the lip rests against the first wall.

Claims

exact text as granted — not AI-modified
1 . A cleaning device, comprising:
 a main body having a roller apparatus and a suction apparatus, the roller apparatus defining a line of movement of the cleaning device, the suction apparatus opening out into a suction opening which is arranged on a side of the main body facing a floor to be cleaned, the suction opening being bordered by a first wall and a second wall, the first wall and the second wall running transversely to a line of movement,   wherein a lip with an elastic design, which when the cleaning device is used as intended lies on the floor to be cleaned, is assigned to the suction opening,   wherein, when the cleaning device is moving in a first direction of movement along the line of movement, the lip rests against the first wall, and while the cleaning device is moving along the line of movement in a second direction, the lip rests against the second wall, and
 wherein 
 the lip is configured such that during movement in the second direction of movement, the lip rests against the floor to be cleaned in a sealing manner and during movement in the first direction of movement, the lip allows liquid to pass through. 
   
     
     
         2 . The cleaning device of  claim 1 , wherein a contact pressure gradient between the floor and lip in the direction of movement is smaller in the first direction of movement than in the second direction of movement. 
     
     
         3 . The cleaning device of  claim 1 , wherein the lip has a supporting body and a sealing body,
 wherein the supporting body is arranged pivotably in the suction opening, and   wherein the sealing body is arranged on an edge of the supporting body facing the floor to be cleaned.   
     
     
         4 . The cleaning device of  claim 3 , wherein the edge of the sealing body assigned to the floor to be cleaned is rounded. 
     
     
         5 . The cleaning device of  claim 3 , wherein the lip has a thickening on the edge assigned to the floor to be cleaned. 
     
     
         6 . The cleaning device of  claim 3 , wherein the supporting body and the sealing body acre strip-like, and
 wherein the sealing body is angled with respect to the supporting body.   
     
     
         7 . The cleaning device of  claim 3 , wherein the sealing body has a recess running at least partially in a longitudinal direction on at least one side of the sealing body. 
     
     
         8 . The cleaning device of  claim 3 , wherein the sealing body comprises elastic plastic and the supporting body comprises dimensionally stable plastic. 
     
     
         9 . The cleaning device of  claim 3 , wherein the lip comprises a two-component injection-molding.
