Abstract
A wheeled suction nozzle is provided having, generally, a simplified three-piece construction including an upper shell, an intermediate plate and a bottom pan, with the intermediate plate sandwiched between the other two members so that its top surface and the bottom surface of the upper shell form the suction passageways for the nozzle. A rotary valve is included to activate edge or normal suction, with this valve rotating on a vertical axis and snapfit into position and thus not requiring any sort of connecting means which would positively maintain the rotary valve attached to the nozzle.
