ABSTRACT:
A filter bag arrangement for a vacuum cleaner includes a bag body of filter material, and a stiffening element in the form of a filter mounting plate with an inlet opening of the bag therein. The vacuum cleaner includes a housing defining a chamber into which the bag may be inserted, a lid to cover the chamber, and a filling pipe stub that is insertable into the inlet opening. Plural individual mounting elements are provided at the outer edge of the stiffening element and are inserted into corresponding individual receivers of the housing so as to spatially position and fix the inlet opening of the filter bag arrangement relative to the housing of the vacuum cleaner.
