Abstract
Abstract The washing of domestic animals, particularly pets, is facilitated by the brush of the present invention which has reservoirs for animal grooming aids such as soap and cream rinse and a hose connected water supply for applying and removing the grooming aids. The reservoirs are maintained under positive pressure by connection to a back pressure chamber in the head of the brush, finger control valves introduce the grooming aids into a mixing chamber and the mixing chamber is also connected to the back pressure chamber. Vortex generators in the mixing chamber mix together the incoming water and the grooming aids and expel the mixture through holes in the brush at the base of the bristles.
