Abstract

The invention relates to an electric vacuum cleaner and the corresponding filter bag (7) which can be removed from a chamber (6) after opening and separating a socket connection. In order to achieve easier, cleaner handling upon changing the filter bag, the chamber (6) is separable by disengagement in a region of the shaft, about which the chamber can pivot, (14) after swinging separation from the filter bag (7).
