The at least one electronic sensor means responsive to a detectable element in or on at least one additional filter by means of electromagnetic waves is connected with the switching means via an evaluating or processing means, adapted to check the correct position and design of the at least one detectable element. The renders possible not only the checking of the presence of an additional filter in the vacuum cleaner but furthermore its right placement and the right design for the respective vacuum cleaner so that impairment of and damage to the vacuum cleaner due to fitting the wrong additional filter may be avoided.
