A method for the operation of a vacuum cleaner for purely strength of a filter element is surrounded by the vacuum cleaner

摘要

The present invention is a method for the operation of a vacuum cleaner (10) for purely strength of a of the vacuum cleaner (10) includes and filter element (16) during the operation of the vacuum cleaner (10), wherein a measured pressure value of a a volume (12, 14), in which the filter element (16) is located, associated pressure sensor (50) is detected and is compared with a threshold value and wherein a downstream of the filter element (16) of the pure gas valve (46) arranged in a function of an exceeding of the threshold value for the ambient air is opened, as well as a corresponding vacuum cleaner (10).
