Abstract

A vacuum cleaner includes a body. A suction generator and a dirt collection vessel are both carried on the body. The dirt collection vessel includes an arcuate side wall, a tangentially directed inlet, an axially directed outlet, a dirt collection chamber and a shroud provided between the dirt collection chamber and the axially directed outlet. The shroud includes a filter surface having a plurality of air flow apertures and a helical step extending around the shroud through the filter surface.
