Last year about this time I posted that my 24 year old 16 gallon Sears vac was dying, even with a new filter and wanted suggestions for a new one. It wasn't dying!! I had about a 50% restriction of some sort of stringy crud in the hose. It seemed to suck pretty well - that is until I went to clean up under my table saw. I 'reamed' out the hose, cleaned up whatever else I could and it's good for another quarter century. The little one, also a Sears 5 gallon (I think), needed a new filter. Got one the same size at HD for about 60% of the Crapsman - works fine now.
