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 in their underbody.
