First Claim
Patent Images
1. A vacuum cleaner comprising:
- a cyclone separator having at least one separator chamber for separating contaminants from a dirt-containing airstream, and further comprising an inlet and an outlet in fluid communication with the separator chamber;
a collection chamber associated with the cyclone separator for receiving contaminants separated in the separator chamber and having a sidewall and a bottom wall;
a suction nozzle fluidly connected with the inlet; and
a suction source fluidly connected to the suction nozzle and to the separator chamber for establishing and maintaining a dirt-containing airstream from the suction nozzle to the inlet;
wherein the collection chamber further comprises at least one circumferential fin extending inwardly from the sidewall.

Abstract
A vacuum cleaner with a cyclone module assembly comprises a cyclone separation chamber for separating dust and debris from air and a collection chamber for collecting dust and debris that is separated from the air in the cyclone separation chamber. The cyclone module assembly further includes at least one feature for directing contaminants downwardly, such as a circumferential fin that extends from the inside wall of the collection chamber or a helical step dividing the separation chamber from the collection chamber.
