  • the elastomer component extends from the non-replaceable pull-off lip 94 along the first side walls 86, 88 of the suction channel 80 to the latching hook 136. This is particularly evident from Figure 5 clear.
  • the first housing half-shell 78 forms an injection molded part with a hard component and the elastomer component.
  • the hard component preferably consists of a polypropylene or ABS material and the elastomer component preferably consists of thermoplastic elastomer material.
  • the hard component forms the walls of the first housing half-shell 78 including the walls of the suction channel 80 and the spring tongue 138, and the elastomer component forms the first pull-off lip 92 and the film hinge 143.
  • the portable hard surface cleaning device 10 can be moved along the hard surface in the manner of a manual window puller for cleaning a hard surface, in particular a window pane or a glass door, by means of the second pull-off lip 92 and the first pull-off lip 94 supporting this on the hard surface of the suction opening 82 can be supplied.
  • the suction channel 80 the liquid can be sucked together with air from the suction opening 82 and fed to the separation chamber 20.
  • the separation chamber 20 can be subjected to a vacuum from the suction unit 14 via the turbine inlet line 20.
  • the mixture of liquid and air flows through the suction channel 80 and, within the separation chamber 22, first meets a baffle plate 144 held at the suction channel end section 30, on which part of the liquid carried is separated.
  • the liquid / air mixture then meets the baffle 24, on which the remaining entrained liquid separates, whereas the sucked-in air flows around the baffle plate 144 and the baffle 24 and reaches the suction turbine 18 via the turbine inlet line 20.
  • the sucked-in air is discharged to the outside from the suction turbine 18 via an annular air outlet space 146 which surrounds the upper tank section 62 within the upper recess 64 in the circumferential direction.
  • the baffle plate 144 forms a first separating element for separating liquid
  • the baffle wall 24 forms a second separating element for separating liquid from the aspirated liquid-air mixture.
  • the liquid separated in the separation chamber 22 can reach the dirty liquid tank 54 via the filling funnel 70 and the filling pipe 58. If necessary, the dirty liquid tank 54 can be emptied.
  • the user can remove the dirty liquid tank 54 together with the filling device 56 held thereon from the base part 12 by pulling the rear tank section 44 out of the lower recess 68 and then removing the upper tank section 62 from the upper recess 64.
  • the user can then use the filling device Detach 56 from the dirty liquid tank 54 and empty the dirty liquid tank 54.
  • the user can then reinsert the filling device 56 into the dirty liquid tank 54 and insert it with the upper tank section 62 into the upper recess 64 and with the rear tank section 66 into the lower recess and lock it with the base part 12.
  • the user has the option of rotating the second pulling lip 92, as explained in detail above, by 180 ° about its central axis 130 to rotate, so that the previously unused pulling edge 104 or 106 can then be used.
  • the portable hard surface cleaning device 10 is characterized by a long service life and can be moved along the hard surface by the user in the usual way in the manner of a manual window puller.
  • the portable hard surface cleaning device 10 is characterized by low manufacturing costs.
