They are vacuum cleaner belts. They fit. They turn the beater bar. They haven't worn out yet. Pretty much what you would expect.

I just replaced the old belt with one of these news ones on my Prolux 8000 and so far everything is ok. At first I thought I had the wrong replacement belts because these are a little wider and thicker and looked a little too short. I think it just looked too short because of being wider because it fit perfectly. So I'm hoping this means they will last longer.

Very pleased with the new Prolux 7000 vacuum cleaner and accessories. It works great.
