Abstract
A vacuum cleaner includes a body having a nozzle assembly with a suction inlet and a control assembly including a control stalk. A dirt collection vessel is carried on the body. The dirt collection vessel includes a toroidal cyclone. The toroidal cyclone has an inlet port, a clean air outlet port and a particle outlet provided in a wall of the toroidal cyclone between the inlet and outlet port. A cork screw baffle is received in the toroidal cyclone. The cork screw baffle defines a spiraling air path through the toroidal cyclone. A suction generator, carried on the body, draws the air stream through the dirt collection vessel.
