    Abstract: A base plate for a vacuum cleaner suction head is described, said base plate comprising a lower face, an upper face and a base plate channel open towards the surface to be vacuumed. The channel extends across the whole width of the base plate. The base plate channel comprises a front edge and a rear edge. The lower face comprises: a first surface which extends along the whole front edge of the channel and a second surface which extends along the whole rear edge of the channel, the first and second surfaces lying in a same horizontal plane. The lower face also comprises a front inclined surface extending from said first surface towards the front side. According to the invention, the front inclined surface is inclined upwards so that the front side is raised with respect to the surface to be vacuumed.
