Carpet Cleaning

We really need to get our carpet cleaned in the bedroom.  It's getting pretty gross.  I've tried all sorts of carpet cleaners, but nothing seems to keep it clean or keep the smells away.  I think I'm going to try a white vinegar mixture next and if that fails, I'll have to hire someone to come clean the carpets.  Might as well do the whole downstairs.  My only concern is I have this huge honking king sized bed frame.  I don't want to take it apart.  Will they clean around it or move it for us?  I think if we take the mattress and supports out, then they could work around the frame.  It's really big and I even hate to think about when/if we move how to get that monster out of the room.  I'm sure I'm exaggerating since when the furniture store people put it together it didn't take them that long.
