A bowl for spraying a coating product, intended to be integrated into a rotary spraying apparatus for spraying a coating product. The spraying apparatus includes a turbine for rotating the bowl about an axis of rotation, and a body that defines the axis of rotation and includes shaping air ejection orifices arranged in a crown. The bowl includes a body which is centered in relation to an axis and which defines an inner radial surface for distributing the coating product to a spraying edge, as well as an outer radial surface. The outer radial surface of the bowl includes a deflector for at least partially directing a flow of cleaning product towards the crown of the body, the cleaning product flowing along the outer radial surface towards the spraying edge.
