A brushroll or agitator is a very important part of a vacuum cleaner. As this will dig deep into you carpets to help pull out the dirt that is harmful to your health and destroying your carpet. Agitators come in a lot of different shapes and sizes. Some are good only for general dirt and some are designed to help clean pet hair.
