Agitation is one of those funny words that have many different meanings but for your carpet it’s a great thing. Carpet Agitation is the act of loosening dirt and other particles from your carpet. This makes it easier for cleaners to remove hard to get to stains from your carpet. For example, when we wash our hands, we are technically agitating the skin to remove excess dirt and germs that might be missed. It’s the same thing for the carpet.
