It would be nice
if one of you experienced vacuum maintenance folks would post a sticky or something on how to maintain a vacuum, especially for those of us with pets and messy family members! Other than changing the bag and belt and taking a retracted ballpoint pen to the brush roll to remove hair, I really don't know what I'm doing, and could profit from your experience!
I have a new Riccar RS 4 Supralite, and don't want it to degenerate into one of the nasty messes I see in those pictures.
