When it comes to vacuuming rugs most on the carpet in our house is wall to wall (low pile) and it works great, but we've recently replaced the carpet and vinyl in the living room/kitchen with hard wood floors and my wife bought an area rug that is shag and it's a SOB vacuuming it, and with my 2 dogs spending most of their time lying around on top of it it need more attention the the other rooms.
