We have a wonderful vacuum and I empty all the time. It picks up tons of stuff all the time. So sadly I never thought about cleaning the rolling brush. ewww! I was vacuuming in the hall way and sucked up Lydia's necklaces and it got stuck so I flipped it over and the brush was totally gone and this is what I found.
Please don't judge me, I have learned my lesson and I promise I will flip the vacuum more often.
