Abstract
A vacuum cleaner with a separation module includes an advanceable filter media for filtering a debris-containing working airstream. The filter media can extend over an exhaust grill having openings through which air may pass. The filter media can be mounted on a pair of moveable reels, such that the filter media can periodically be replaced with new filter media.
Claims19
A vacuum cleaner, comprising:
- a housing comprising a suction nozzle;
- a suction source provided on the housing in fluid communication with the suction nozzle for creating a working airstream through the housing;
- and
- a cyclone separator having at least one separation chamber for separating contaminants from the working airstream and comprising an air inlet in fluid communication with the suction nozzle and an air outlet;
- a collection chamber adjacent to the cyclone separator for receiving contaminants separated by the cyclone separator;
- a filter assembly positioned within the separation chamber, the filter assembly comprising:
- a supply reel;
- a take-up reel;
- and
- a filter media wound about the supply reel and connected to the take-up reel, and positioned within the path of the working airstream to filter air passing through the filter assembly;
- wherein the filter media can be advanced from the supply reel to the take-up reel by rotation of the supply and take-up reels.
