摘要:
A vacuum cleaner is provided having a suction nozzle comprised of a transparent agitator housing and an opaque suction nozzle body. The agitator housing forms a downwardly disposed nozzle chamber divided into a right and left agitator chamber. The right and left agitator chambers each have a forward or front suction duct adjacent the front edges of the respective agitator chambers. The right and left agitator chambers also each have a rearward or rear suction duct adjacent the rear edges of the respective agitator chambers. A nozzle liner is also disposed within the nozzle chamber partially forming a right and left dirt and air passage over the right and left agitator chambers, respectively, to fluidly connect the respective front suction ducts with the rear discharge ports located in the rear of each of the right and left agitator chambers. The rear suction ducts are also fluidly connected to respective rear discharge ports to remove dirt particles. The front and rear stringers of bottom plate of the foot serve as ledges or bottom walls of the respective front and rear suction ducts. Dirt particles flung onto the ledges by the front and rear agitators are momentarily captured on the ledges before being removed by the respective front or rear suction duct.
