I inherited a 1980's Hoover Concept Two vacuum cleaner when I bought a house 10 years ago. I've recently started burning through belts like crazy, which I think is related to roller bearing shooting. I thought I needed a new roller assembly which is no longer made. Luckily these bearings are the same as in the video on my old vacuum, and installing it made the vacuum work like new. While Hoover keeps releasing new stands, it's nice to see that some of the basic details remain the same.
