Abstract
A suction nozzle assembly for a vacuum cleaner, which has a suction spout having a coupling stem for fluid-connection with the vacuum cleaner, a generally rectangular nozzle housing tiltably connected with the suction spout and having a sweeping surface defined at the bottom thereof and adapted to confront a surface to be cleaned, an elongated brush assembly carried by the nozzle housing for movement between projected and retracted positions in a direction perpendicular to the longitudinal sense of the housing through the sweeping surface, a brush height adjustment device for adjustably moving the brush assembly to any one of the projected and retracted positions, and a restraint device for restraining the housing from undergoing an arbitrary tilting motion relative to the suction spout.
