Abstract: A separating apparatus for a vacuum cleaner has a cyclonic separating chamber having a separator axis, a shroud disposed within the cyclonic separating chamber, an inner debris collection chamber for collecting debris separated by the cyclonic separating chamber, and an outer debris collection chamber for collecting debris separated by the cyclonic separating chamber. The inner debris collection chamber has a base and a debris outlet in fluid communication with the outer debris collection chamber. A shortest distance between the shroud and the base in a direction parallel to the separator axis is between 40% to 60% of a largest distance between the cyclonic separating chamber and the base in a direction parallel to the separator axis.

Abstract: A separating apparatus for a vacuum cleaner has a first separating unit and a second separating unit movable between a first position and a second position with respect to the first separating unit. The separating apparatus has a collection chamber having an end wall movable between a closed position for collecting debris separated by the first separating unit, and an open position for removal of debris collected by the collection chamber. Movement of the second separating unit from the first position to the second position causes movement of the end wall from the closed position to the open position, and movement of the second separating unit from the second position to the first position causes movement of the end wall from the open position to the closed position.

Abstract: A vacuum cleaner comprising a dirty air intake and a cyclonic separating apparatus connected in series. The cyclonic separating apparatus comprises a plurality of cyclonic separators connected in parallel. The vacuum cleaner further comprises a bleed valve provided upstream of the plurality of cyclonic separators. The bleed valve opens to admit bled air into the plurality of cyclonic separators in response to a drop in pressure in the vacuum cleaner. The bleed valve is also connected to the inlets of the plurality of cyclonic separators via a common plenum.

Abstract: A separating apparatus for a vacuum cleaner has a cyclonic separating chamber, an inner debris collection chamber for collecting debris separated by the cyclonic separating chamber, and an outer debris collection chamber for collecting debris separated by the cyclonic separating chamber. The inner debris collection chamber has a main body and a base mounted to the main body by a hinge. The hinge is formed of an elastomeric material.
