In the present case, the amount of the third angle of inclination N3 is smaller than the first angle of inclination N1 and / or the second angle of inclination N2.
  • the warning signal W is first emitted.
  • the suction drive 9 and / or the tool drive 12 are automatically switched off only when the hand-held guide part 2 is pivoted beyond this and when the first angle of inclination N1 and / or the second angle of inclination N2 is reached.
  • the detection device 25 is also set up to detect the filling level H of the receptacle 7.
  • the control device 20 is also set up in such a way that the protective function described above can also be controlled as a function of the fill level H.
  • the detection device 25 has a level sensor 34 which is set up to detect the level H.
  • the filling level sensor 34 is designed in the form of a capacitive sensor, which is located outside the receiving container 7 in the Fig. 2 visible area of the support tube 5 is arranged.
  • Such level sensors 34 are known in principle.
  • the computing unit 31 is set up in the present case in such a way that the angles of inclination N1, N2 and N3 can be determined variably as a function of the detected fill level H.
  • angles of inclination N1 to N3 are functionally dependent on the fill level H and are calculated as a function of this by means of the computing unit 31. If the detected fill level H is comparatively low, this allows for larger angles of inclination N1 to N3 in terms of magnitude, without there being the risk of unwanted liquid being drawn in through the air intake opening 23. Conversely, the angle of inclination N1 to N3 is smaller in terms of amount, provided that the level H is comparatively high.
