Abstract (en)
[origin: EP2457487A2] The device has a resonator element (5) held at an outer wall (4) of a dirt collection container (1). An excitation element (6) i.e. piezo element, excites the resonator element for mechanical vibrations. Detection units (9) detect variables that characterize damping of the mechanical vibrations. The detection units determine a filling level of the dirt collection container dependent upon the determined variable. The resonator element is designed as a vibration body and an elastic membrane (5-1), which is made of rubber on latex base. An independent claim is also included for a vacuum cleaner that comprises a centrifugal force separator.
