Abstract
A nozzle assembly is provided for a suction cleaning device. The nozzle assembly includes a body having an edge and a bottom wall. The bottom wall includes an intake opening and a portion extending between the edge and the intake opening. At least one channel is provided within that portion. That channel extends between the edge and the intake opening and has a cross sectional area decreasing in a direction extending from the edge toward the intake opening. Air drawn through the channel is accelerated as it approaches the intake opening in order to increase the dirt, dust and debris entraining capacity of that air and overall vacuum cleaner cleaning efficiency.
