Have any of you run into this annoying problem?

We(wife)bought a vacuum cleaner that was EXTREMELY expensive. It has all the bells and whistles, along with a thousand attachments but it seems every time I use it, I battle trying to suck up a little piece of thread off the carpet! It really pisses me off! For something that costs that much money, a little hand should come out and pick the thread up, I shouldn't have to bend over!
