A carpet rake is a tool that is used to remove loose particles from the surface of a carpet. It is also used to level the pile of the carpet.
The first step in using a carpet rake is to shake it out and make sure that all of the bristles are facing downwards. The second step is to insert it into the pile of the carpet and pull it towards you, using your arm as leverage. Next, turn your body slightly and repeat this process until you have reached the other side of your room or until you have removed all of the loose particles from your floor.
