Abstract (en)
[origin: EP2384679A2] The device (40) has a filter replacement indicator (48) operated by an operating element (50) based on thermal expansion, where the operating element includes a thermally expandable medium (52) i.e. wax. The operating element has an operating lever (54) that is moved with the thermal expansion of the medium. The indicator has a mechanical counter for adjusting change marking based on a predetermined number of operations by the operating element. A counter operating lever is operated by the operating lever, where the indicator device is arranged lateral to a filter medium. An independent claim is also included for a vacuum cleaner comprising a filter.
