Bought this replacement roller for my Kirby who only uses 2 small bedrooms. I probably vacuum every 2 weeks as these are vacant bedrooms. One of the roller bearings got stuck last month. My only option was to try and see if the bearings were sealed or if I could lubricate. The end of the video broke off. The Orig KIRBY roller has lasted 25 years and has been used weekly around the house. GARBAGE!
