What Is a Beater Bar on a Vacuum and How Does It Work?
A beater bar, also known as a brush roll or agitator, is a rotating brush located near the bottom of a vacuum cleaner. It helps to loosen and agitate dirt and debris from carpets and other surfaces, making it easier for the vacuum to suction them up. The beater bar is typically powered by the vacuum’s motor and may be adjustable or removable for different types of flooring.
