Abstract: A filtration assembly (100) for a vacuum cleaner includes a filtration member (1) for filtering an impurity, in which an outer circumferential wall of the filtration member (1) is provided with a fixing frame (11) adapted to be fixed in the vacuum cleaner; and an ash tapping part (2) which includes a rack (21), a moving member (22), a gear (23) and a tapping member (24). Two ends of the rack (21) are fixed to the fixing frame (11), the moving member (22) is movably disposed to the rack (21), the gear (23) is disposed to the moving member (22) and meshes with the rack (21), the tapping member (24) is disposed to the gear (23) through a connecting shaft (241) so as to be driven to rotate by the gear (23), and the tapping member (24) is configured to tap the filtration member (1) during rotation to vibrate the filtration member (1).

Abstract: A cyclonic separating device includes: a first cyclonic separator defining a first longitudinal axis; a plurality of second cyclonic separators located downstream of the first cyclonic separator, arranged circumferentially around the first longitudinal axis in parallel, and integrally received in the first cyclonic separator; an inlet passage at least partially received in the first cyclonic separator; a guiding passage communicated with the inlet passage and the first cyclonic separator respectively, in which a fluid introduced through the inlet passage is tangentially guided into the first cyclonic separator by the guiding passage. In addition, a surface cleaning apparatus, a cleaner and a method for separating dust from a dust containing air using the cyclonic separating device are further provided.
