Device for cleaning brushes

Abstract

A device ( 1 ) for cleaning brushes, in particular brushes for hair or animal fur, comprising a container ( 12 ), at least a rotary counter-brush ( 2 a , 2 b , 2 c ), inserted inside the container ( 12 ) and able to act on at least a brush to be cleaned ( 4 ). The counter-brush includes bristles which are arranged along preferential lines along an external surface of a body of the counter-brush, the lines being distanced from one another by spaces which are sufficient to enable a winding of the hairs or fur along the body of the counter-brush.
