Abstract: A vacuum cleaner includes a filtration chamber with an inner wall and an outer wall, an air inlet arranged to feed air carrying dust particles into the space between the inner wall and outer wall of the filtration chamber and a dirt chute for discharging dirt and/or dust from the vacuum cleaner. A tapered filter is located between the inner wall and the outer wall of the filtration chamber. The tapered filter includes a narrow end and a wide end, and the narrow end of the filter is located at or proximate to the air inlet and/or the dirt chute.

Abstract: A dirt separator for a vacuum cleaner includes a first separation stage having a first dirt collection chamber; a second separation stage downstream of the first, the second separation stage having a second dirt collection chamber; a lid movable between closed and open positions to selectively block and unblock an emptying aperture provided in the first dirt collection chamber; and a latch mechanism. The first and second dirt collection chambers are movable relative to one another. The latch mechanism is configured to secure the dirt collection chambers in a first position, and to secure the lid in the closed position. The latch mechanism is configured to allow the first and second dirt collection chambers to move towards a second position, and to allow the lid to move towards the open position, when the latch mechanism is in the releasing configuration.
