A fluid driven assembly for a rotary brush comprising a housing. The housing has a top side and bottom side which converge moving toward an opposite end relative to an inlet end for fluid, thus providing a very low profile assembly, resulting in limited internal cavity space for mounting the fluid driven mechanism. Within the housing cavity is a rotary brush mounting adaptor, with affixed gear teeth, for removably mounting such a rotary brush facing out of an opening in the bottom of the housing and with the adaptor and affixed gear teeth rotating about an axis extending out of the opening. Also in the housing is a waterwheel, with affixed gear teeth, rotating about a second axis displaced toward the inlet end from the first axis. The adapter and waterwheel gear teeth are in driving engagement and water vanes on the waterwheel are axially displaced toward the top side from the adaptor and waterwheel gear teeth.
