Vacuum

My sock fell behind my bed. I want to vacuum it up, but I need to use the 'crevice tool'. The hose itself would suck the sock up, and I only need to get it from behind the bed. Is 'crevice tool' the right word? What I mean is the attachment you put on the end of the hose. It's usually used to vacuum narrow spaces, so it'd not suck the sock in. It'd only help me get the thing out.

Thank you.
