Dyson vacuum owners please calm my fears...

I have recently purchased a Dyson Animal DC 14.
I have vacuumed my rugs for a few days-thoroughly. Each day it looks like it sucks up a gerbil (based on the amount of stuff in the cannister).

Were my rugs really that dirty? If so, I would think that it would eventually reach a point where there wasn’t so much stuff in the cannister.

or

Is this thing destroying my area rug a fiber at a time?
