Abstract
A vacuum cleaner canister includes a mechanism cooperable with the canister inlet duct to divide the canister into an upper zone of high velocity vortex air flow and a lower zone of reduced velocity air flow so as to reduce the likelihood of recycling particles through the vacuum cleaner filters. The inlet duct is positioned below the filters. The duct redirects air flow downwardly from the inlet port into the canister and a baffle redirects the downward flow to a circumferential flow.
Claims9

- a canister having an inlet port;
- a duct directing air flow from said inlet port downwardly in said canister;
- and
- a baffle disposed in a non-perpendicular plane relative to the downwardly directed air flow and co-operating with said duct to divide said canister into an upper zone of vortex air flow and a lower zone of reduced-velocity air flow.
