A rotary brush is used with a machine that spins it on a cylinder or a ring with the bristles pointing downwards. Rotary brushes can be manufactured in a variety of configurations and they are usually made to be replaceable once the bristles wear out from too much use.

Applications of Rotary Brushes
These brushes can be found on automatic shoe polishers, street cleaners, and conveyor belts. In any industry where heavy duty cleaning equipment is needed, there is usually a piece of equipment that is fitted with a series of durable rotary brushes to get the job done. Rotary brushes are used on most street sweeping machines to remove dust and debris from the street. A series of rotating brushes points downward on the front of the vehicle, gathering up dirt as the brushes spin and make contact with the pavement. A street sweeper will usually have gutter brooms on the outside that spin inward, guiding the dirt to a large rotary brush that sweeps it into the street sweeper’s vacuum system.
Very large rotary brushes mounted on a long cylinder are also used to clean runways at airports. A runway sweeper removes any unwanted dirt and debris from the surface of the runway, reducing the chance of accidents or other complications during takeoff and landing. A rotary brush can also be made using stainless steel wire for heavy duty cleaning and deburring applications.
When a rotary brush is mounted on a conveyor belt, it is typically used as part of an automated cleaning process. Parts or complete products are moved beneath the rotary brush along the conveyor belt, and they are scrubbed as they come into contact with it. One example of this is in potato processing and packaging. After the potatoes have been sent through a water wash, they are moved under a rotary brush that removes any gritty dirt from their surface before they are dried off and packaged. Over time, the bristles of the brush will wear down and need to be replaced to effectively clean products.
