ABSTRACT:
A vacuum cleaner uses a special self-cleaning filter arrangement including an initial fabric filter having a relatively large mesh size with a broad open mesh ratio of 5 to 11 flat filter threads 0.025 to 0.045 inches in width defining oblong filter openings 0.002 to 0.006 inches in width and having a length not greater than will maintain the structural integrity of the filter openings and a total opening area of 5 to 45 times the cross section of the inlet, which inlet faces away from the filter. The initial filter is preferably backed up by secondary filters which filter particulates passing through the initial fabric filter especially during startup and while the filter cleans itself.
