The head assembly includes a head junction, and a plurality of heads attached to the head junction. The heads include a pair of side heads having opposed bristles, and a forward head. The side heads substantially perpendicularly downward from the head junction, and the forward head extends at an obtuse angle from the head junction. A middle head is located immediately beneath the head junction. Both side heads and the forward head are each attached to the head junction with a U-joint which allows each head to flex with respect to the head junction.
