         9 . The cleaning module according to  claim 1 , wherein
 the first rolling brush and the second rolling brush are arranged one behind the other side by side in a direction of movement of the cleaning module.   
     
     
         10 . The cleaning module according to  claim 1 , wherein
 the first brushes spirally extend in an axial direction of the first rolling brush; or   the second brushes spirally extend in an axial direction of the second rolling brush.   
     
     
         11 . The cleaning module according to  claim 6 , wherein
 a thickness of the first long brush is less than or equal to a thickness of the first short brush; or   a thickness of the second long brush is less than or equal to a thickness of the second short brush.   
     
     
         12 . The cleaning module according to  claim 1 , wherein
 the first rolling brush comprises a first support, the first support being provided with a supporting surface that supports a first brush member in a contact manner, and at least a part of the supporting surface being incompressible; or   the second rolling brush comprises a second support, the second support being provided with a supporting surface that supports a second brush member in a contact manner, and at least a part of the supporting surface being incompressible.   
     
     
         13 . The cleaning module according to  claim 12 , wherein
 the supporting surface of the first rolling brush is incompressible; or the supporting surface of the second rolling brush is incompressible.   
     
     
         14 . The cleaning module according to  claim 6 , wherein
 the first long brushes and the second short brush are arranged opposite to each other when the first rolling brush rotates; or   the second long brushes and the first short brush are arranged opposite to each other when the second rolling brush rotates.   
     
     
         15 . The cleaning module according to  claim 1 , wherein the first brushes and the second brushes are staggered.
