Abstract
The present invention relates to an arrangement of filter bags in electric vacuum cleaners in which the filter bag has a bottom plate which has an insertion opening for a fan-side air-blast socket and at least one side-edge indentation (28) and is arranged as a transverse wall in a filter-bag chamber (6) which is adjacent a motor-fan housing (5) and can be lifted off from it. A second side-edge indentation is disposed opposite first side-edge identation and housing-side profections extend into both indentations and protrude beyond the lower side of the bottom plate.
