       2 . The cleaning apparatus of  claim 1 , wherein said front mounting groove has a cross-section that is shaped like the letter L. 
   
   
       3 . The cleaning apparatus of  claim 1 , wherein said front mounting groove has a circular cross-section. 
   
   
       4 . The cleaning apparatus of  claim 1 , wherein said upper wall has a protrusion that extends inward, and said held part has a blocking shoulder that engages therewith. 
   
   
       5 . The cleaning apparatus of  claim 4 , wherein said protrusion of said upper wall has a trapezoidal cross-section. 
   
   
       6 . The cleaning apparatus of  claim 1 , wherein said lower wall carries a load distribution plate. 
   
   
       7 . The cleaning apparatus of  claim 1 , wherein said lower wall has an end with an end part separated therefrom by a gap, with a blocker protruding from said end part on an inner side. 
   
   
       8 . The cleaning apparatus of  claim 7 , wherein said blocker has an increasing width towards said end of said lower wall. 
   
   
       9 . The cleaning apparatus of  claim 7 , wherein said end part carries an extension piece. 
   
   
       10 . The cleaning apparatus of  claim 1 , wherein said upper wall has a plurality of threaded holes, with a plurality of bolts that respectively enter said plurality of threaded holes fastening said wiping strip. 
   
   
       11 . The cleaning apparatus of  claim 1 , further comprising a cleaning head, wherein said main body has a rear mounting groove, which is oriented parallel to said front mounting groove and which has a bottom and at least one fastening hole in which said cleaning head is mounted, and a chamber between said front and rear mounting grooves, and wherein said cleaning head further comprises a holder, which fits into said rear mounting groove, a cleaning element, attached to an outer side of said holder, and at least one hook, shaped like the letter L with an arm and mounted in said fastening hole; wherein said cleaning head is mounted by putting said arm of said at least one hook put through said at least one fastening hole, until said at least one hook extends into said chamber, and moving at least one hook transversely, until being fixed in said at least one fastening hole. 
   
   
       12 . A cleaning apparatus, comprising:
 a main body, to which a handle is fastened, having a rear mounting groove which has a bottom and at least one fastening hole; and   a cleaning head, fastened to said main body on a rear side thereof and further comprising a holder, which fits into said rear mounting groove, a cleaning element, attached to an outer side of said holder, and at least one hook, shaped like the letter L with an arm and mounted in said at least one fastening hole.   
   
   
       13 . The cleaning apparatus of  claim 12 , wherein, for each of said at least one fastening holes, close thereto a projection is placed on said bottom on an outer side thereof, and wherein, for each of said at least one said hooks, said arm thereof has a free end with an inclined surface and an incision engaging with said projection of one of said at least one fastening holes. 
   
   
       14 . The cleaning apparatus of  claim 12 , wherein said cleaning element comprises a fixed part and a wiping part, attached to an outer side of said fixed part, and wherein said holder further comprises an upper assembly, which is shaped like a strip and on a lower side has teeth and fixing holes, and a lower assembly, which is shaped like a strip and on an upper side has teeth and pegs, which pass through said fixing holes of said upper assembly, wherein said teeth of said upper and lower assemblies hold said fixed part of said cleaning element to said holder.
