  • the dust filter 10 is also designed to be washable and wringable with the first frame structure 2, thus enabling an advantageously thorough and simple cleaning for the user.
  • advantages of the invention are that the relatively soft first frame structure 2 with the dust filter 10 can be better supported against the suction air flowing through it and that the cleaning of a dust filter 10, further residual dust filters and their handling in a vacuum cleaner 1 can be improved.
  • the dust filter 10 can be easily removed from the vacuum cleaner 1 or the Staubabscheidetician 5 of the vacuum cleaner 1, cleaned and then connected to the Staubabscheidetician 5 again.
  • a particular advantage is the fact that can be wrung out, knocked out and possibly also washed by dispensing with a very rigid grid structure as a carrier of the dust filter 10, the dust filter 10 and the first frame structure surrounded by it.
  • the first frame structure 2 together with the second frame structure 3 helps to reinstall the dust filter 10, so that this process can be simplified for the user.
  • the reusability of the dust filter 10 is improved, whereby for the user a longer service life at the same Filter performance is enabled and the environmental impact can be reduced by reducing the amount to be disposed dust filter material.
