Cylindrical coil brushes might be seen on vacuum cleaners, street sweepers or an industrial compound applicator. Also called a shaft cleaning brush, a cylindrical coil brush is a long strip brush wound in a helical fashion to create a cylinder. These can be near any diameter and length, depending on the job they need to perform. Further, some of these internal cylindrical coil brushes or shaft cleaning brushes can be closely wound so that they appear as solid cylinders. Others may  have spaces between winds depending on the task at hand.
