This spraying member (10) comprises at least one outer bowl (100) and one inner bowl (200), each bowl defining a spraying edge (101, 201), one inner spreading surface (102, 202) and one outer surface (103, 203). The inner bowl (200) is positioned radially on the inside of the outer bowl (100), whereas a volume (V1) defined between the inner surface (102) of the outer bowl (100) and the outer surface (203) of the inner bowl (200) has a thickness (e), corresponding to the distance between this inner surface (102) and this outer surface (203), decreasing between a first value (e1), taken at the zone for inlet of cleaning product into the volume (V1), and a second value (e2), taken at the spraying edge (101) of the outer bowl (100). The spraying member (10) comprises means (68) for the central supply of the inner spreading surfaces (102, 202).
