  • Fig. 11 shows this filter assembly 30 inserted in the drive unit container outer housing 12.
  • the filter assembly 30 of the further filter stage 8 consists of a first frame element 31 with a central opening 32 and a sealing element 33 to the drive unit housing 15 ( Fig. 1 ), a second frame element 34 and a filter medium 35, which is glued between the two frame elements 31, 34 and can also be held in a stable shape, preferably without further support elements.
  • the The embodiment of the first frame element 31 shown here which is shown in the detailed view of Figure 11b can be seen enlarged, represents a 2-component component, wherein a soft component area 36 forms the central opening 32 with the corresponding sealing element 33.
  • a centrally arranged immersion geometry 37 for the cleaning axis 23 is provided on the second frame element 34.
  • the cleaning axis 23 is thereby connected to the external actuating element 27.
  • the second frame element has a circumferential collar 38, which is inserted into the separator container outer housing 15 ( Fig. 11 ) immersed.
  • the direction of flow through the filter medium 35 from the outside to the inside causes the fine dust to be deposited on the outside of the filter medium 35.
  • the central filter of the further filter stage 8 has a cylindrical basic shape, the filter medium 35 being pleated, arranged along the cylindrical shape and an inner area of the central filter 8 separates from an outer area of the central filter 8.
  • This mechanical cleaning device 22 for loosening dirt adhering to the filter medium 35 of the central filter 8 has a cleaning axis 23 which rotates in the central filter 8 to loosen the adhering dirt and which is provided with blades as pulse generators 24. These are designed to exert impulses that loosen the adhering dirt on the filter medium 35 from the rotary movement of the cleaning axis 23. This makes it easy to loosen dirt adhering to the filter medium 35, since the impulses that are triggered knock off the dirt particles. If the user of the vacuum cleaner 100 rotates the cleaning axis 23 using the rotary knob 27, the collected dust is detached from the filter medium 35.
  • the dirt particles released by the pulses fall off the filter medium 35 of the central filter 8 and can thus be removed from time to time from the filter space in which the central filter 8 is arranged.
  • the drive unit container outer housing 12 can be opened and the dust that has fallen from the filter medium 35 of the further filter stage 8 as a result of the back cleaning passes the drive unit housing 15 via the drive unit container 2 together with that via the first filter stage 6 and the second Filter stage 7, the dirt separated out can be emptied.
  • the filter assembly 30 of the further filter stage 8 can also be removed from the separation container 3 for cleaning.
  • the sealing element 33 which is shown in FIG Figure 11a is shown in an enlarged detail view. This sealing element 33 can be designed as a lip seal or an H-shaped seal made of a rubber material or the like.
