This is based on the exemplary embodiments according to FIGS Figures 7 and 8th explained in more detail.
  • FIG 7 the floor nozzle 10 is shown, in which the floor installation device 156 is in an operative position and thus the floor nozzle 10 is in a hard surface cleaning function. In this position, a hard surface 158 can be sucked off as the surface 30 to be cleaned via the floor nozzle 10.

  • the floor nozzle 10 for the textile surface cleaning function has an additional flow path 102, 102 'for each of its suction edges 74, 76 or only one suction edge 74 or 76, via which air from the environment on an outside of the suction mouth 48 of the respective suction edge 74, 76 can be provided.
  • the floor nozzle sucks less on the textile material and the pushing force that is necessary to move the floor nozzle on the textile material is reduced.
  • an outlet 116 or 120 can be closed or its cross section can be adjusted in order to enable adaptation to textile material.
  • one or more openings 122, 122 'are arranged close to the corresponding suction edge 74 or 76 on a corresponding bottom wall 78 or 90, which in turn correspond to the respective outer side 62b, 64b of the corresponding boundary wall 50, 52 on which the suction edge 74 and 76 are formed, are assigned.
  • the suction air in the additional air streams 118, 118 ' has a shorter path through the textile material and is less restricted. As a result, there is a large volume flow at the corresponding suction edge 74, 76.
  • the floor nozzle 10 When the floor nozzle 10 is in operation, it is connected to a suction unit 12. In particular via a suction pipe, an operator moves the floor nozzle 10 over the surface 30 to be cleaned.
