I had a problem with my Kirby vacuum I actually didn't use it for a few months until a salesman showed up at my door trying to sell me a Kirby vacuum (he wanted me to get it in a newer model) I gave up. I told him I have Kirby but he doesn't work as well as he used to. He asked me to pull it out - showed me the strap was stretched so he just stopped spinning the brush. He gave me a new belt and went on my way. Nice man! Well, the problem started again. So I bought them along with some vacuum bags. So now I change the belt every time I change my bag ;-) Works great!
