If the mechanical stress drops away as the user removes the wiper lip 14 from the hard surface, the suction unit 30 is automatically switched off.
  • FIGS. 4 and 5 a second advantageous embodiment of a Hart vomabsaug réelles invention is shown, the total with the reference numeral 100 is occupied.
  • the Hart vomabsaug réelle 100 is designed substantially identical to that described above with reference to the FIGS. 1 to 3 described Hart vomabsaug réelle 10.
  • For identical components are therefore in the FIGS. 4 and 5 the same reference numerals as in the FIGS. 1 to 3 and with respect to these components, reference is made to the foregoing explanations to avoid repetition.
  • the Hart vomabsaug réelle 10 differs from the Hart vomabsaug réelle 100 fact that instead of the microswitch 40, with which a movement of the upper housing part 58 can be detected relative to the housing base 56, a deformation sensor in the form of a strain gauge 102 is used, which is integrated into the flexible wiper lip 14 and detects their elastic deformation during pressing against the hard surface.
  • the strain gauge 102 is in electrical connection with the data processing element 78 via a measuring line, not shown in the drawing to achieve a better overview, and provides a measuring signal when the stripper lip 14 is deformed, which is detected by the data processing element 78.
  • the upper housing part 58 with the lower housing part 56 is releasably connectable.
  • the upper housing part 58 is subject to a slight elastic deformation.
  • strain gauges 102 may in the in the FIGS. 4 and 5 embodiment shown, a strain gauge 104 are used, which is fixed below the wiper lip 14 on the inside of the handle 12 remote from the housing wall 106 of the housing upper part 58.
  • the strain gauge 104 is in FIG. 4 shown in dashed lines.
  • strain gauge 104 can be detected from the pressing of the wiper lip 14 against a hard surface mechanical stress of Hartvidaug réelles 100, and the output of the strain gauge 104 in the same way as the output signal of the strain gauge 102 for automatically switching on and off of the suction unit 30th be used.
  • the control device 108 of the hard surface suction device 100 is in FIG. 5 shown in the form of a block diagram.
  • An acceleration sensor 82 is omitted in Hartvidabsaug réelle 100.
  • the suction unit 30 is the Hartvidabsaug réelle 100 reliably on and off automatically due to the output signals of the strain gauge 102 and / or the strain gauge 104.
  • the wiper lip 14 When pressing the wiper lip 14 against the hard surface, the wiper lip 14 as well as the upper housing part subject
  • the elastic deformation, which is detected by the strain gauges 102, 104, and the removal of the wiper lip 14 from the hard surface eliminates the elastic deformation, which is also detected by the strain gauges 102, 104.
  • the suction unit 30 can thus be switched on and off in a simple manner.
  • a prerequisite for the automatic switching on and off of the suction unit 30 is also in Hart vomabsaug réelle 100, which has made the user ready for operation, either by means of the button 52 or through Grasping the handle 12, if the touch sensor 54 is used.
  • the timer 80 is used in Hart vomabsaug réelle 100 as additional safety shutdown, with which it is ensured that the suction unit 10 is switched off regardless of a possible mechanical stress of the Hartvidabsaug réelles 100 after a predetermined time interval.
  • the suction unit 30 can be automatically switched on and off by the detection of the mechanical stress, which is subject to the Hartvidabsaug réelle 10 or 100 when pressing the wiper lip 14 against a hard surface.
  • the battery 72 is thus discharged only during the actual cleaning process, so that the power consumption of the Hartvidabsaug réelle 10 and 100 can be kept low.
  • the Hartvidabsaugsammlung 10 and 100 are characterized by easy handling.
