Abstract
A vacuum cleaner construction having a filter bag mount movably mounted to the base of the vacuum cleaner canister. Biasing structure is provided for causing the bag mount to extend into an obstructing disposition relative to the hood of the canister preventing closing of the hood in the absence of a filter bag being mounted to the bag mount. Mounting of the filter bag to the bag mount causes a movement of the bag mount against the biasing structure to a lowered disposition within the dirt-collecting space of the canister base, permitting the hood to be closed. The bag mount includes improved sealing structure for facilitated sealed connection of a suction hose end thereto, with the hood maintained in a closed disposition. The bag mount includes an annular seal for sealing the hose connection thereto and an annular flange for removably securing the filter bag mounting plate thereto.
