I had an old "56" Kirby that finally bit the dust. I had it maintained every couple years. I used to take the bag off and just let it air out after use. I use to beat it to get the excess dirt out. I also used to keep baking soda sachets in the bag.. If you can't handle the scented sheets (I can't) Bounce carries the Febreeze free unscented dryer sheets. When I can, I open the windows when I vacuum. Even in winter!
