A suction head for floor vacuum cleaners has a unitary plastic housing (1) containing a suction channel (2), and a bottom plate (7) arranged on the underside of the housing and having a suction mouth (13). The suction mouth adjoins a vertically aligned, box-shaped connection element (14) of the suction channel and feeds into a bottom channel (15) of the bottom plate (7). The bottom plate (7) is pivot-mounted both on the connection element (14) of the suction channel and also at the end side on the inner surfaces of the plastic housing (1). For this purpose, the box-shaped connection element (14) contains transverse bridges (17) that define the suction channel laterally and which have bottom edges designed as bearing surfaces (18) rounded in a curved manner. The bottom plate (7) is supported on the curved, rounded support surfaces (18) of the connection element (14), and rotatably interlocked with the wall surfaces of the connection element (14) extending parallel with the transverse bridges.
