ABSTRACT:
A vacuum cleaning apparatus is provided having a canister, a motor mounted to the exterior of the canister, a cyclonic cone centrally disposed within said canister, an inlet port in the canister wall opposing the cyclonic cone, an outlet port above the cyclonic cone and a primary filter within the canister between the lower end of the cyclonic cone and the canister bottom wall. When the motor pulls air from the canister through the outlet port, dirt laden air entering the inlet port passes the cyclonic cone and downwardly spirals around the cyclonic cone and passes through the primary filter. The filtered air is then pulled upwardly through the interior of the cyclonic cone and exits through the outlet port. A secondary filter can be interposed between the outlet port and the primary filter for additional air filtration.
