Abstract
Disclosed is a self cleaning rotary brush with means for accumulating collected hair for disposal. The invention includes a primary cleaning cylinder with a series of tines that are adapted to clean the fur of the animal. The invention further includes a secondary cleaning cylinder with associated tines that are designed to intermesh with the tines of the primary cylinder. A collection tray is located to the rear of the secondary cleaning cylinder. As fur is collected by the primary cylinder, it is removed by the tines of the secondary cylinder. Thereafter, as the secondary tines come into contact with the edge of the collection tray, the fur is deposited within the collection tray for subsequent disposal.
