The motorized animal-grooming brush is adapted for use with animals. The motorized animal-grooming brush is a rotating brush that is driven by an electric drive that is separated in distance from the rotating brush. The motorized animal-grooming brush comprises a brush device, an electric drive, and a drive line. The electric drive provides a motive force through the drive line to the brush device. The brush device receives the motive force from the electric drive and uses this motive force to rotate the grooming brush. The separation by distance between the electric drive and the rotating brush reduces the level of noise heard by the animal.
