Dear Fuller Brush Man, Is there any brush that will lift the pile on a living room carpet when the "feet" of the furniture have left deep impressions?

Anne,

While we don't have anything specifically designed for that problem, I would first suggest using our Super Foam Rug Shampoo to help loosen up the carpet threads.  Let that sit as directed for a few minutes. Then, using something like our Brush Cleaner, gently pull up the threads to help them return to their previous state.  You can also use a scrub brush of some sort, but you risk further matting.
