A floor cleaner with an air inlet, an air outlet, a suction motor, and a filter. The filter includes a first media layer, a second media layer, an end cap, and an annular cap. The first media layer and the second media layer extend along a filter axis between the end cap and the annular cap. The filter is compressible along the filter axis between the end cap and the annular cap.

A dust remover for a vacuum cleaner, in which dust adhering to a plurality of filters having a cylindrical shape for filtering dust introduced into the vacuum cleaner is removed by repeatedly hitting an inner wall of each of the plurality of filters through rotation of a motor, includes a filter support plate having a plate shape; a plurality of filters arranged spaced apart from each other at regular intervals below the filter support plate in a circumferential direction; a hitting module rotatably provided on the filter support plate to extend to an inner space of each of the filters and configured to hit an inner surface of each of the filters; and a pressure control damper rotatably provided on the filter support plate and configured to optionally open/close a suction pressure of each of the filters.
