ABSTRACT:
A vacuum cleaner suction nozzle is provided with inner front and rear ducts and a duct cover piece disposed within the agitator chamber. This chamber is formed by a tunnel piece that is at least partly user observable from above the nozzle. The nozzle includes a hood piece which melds with its underbody at, at least, a portion of their juncture. This is occasioned by an offset or undercut formed in one of the hood piece or underbody, whereby the hood piece and underbody join with coplaner outer surfaces.
