Abstract
A vacuum cleaner includes a housing having a nozzle that incorporates an agitator cavity. A rotary agitator is received in the agitator cavity. A light source is held in an illumination compartment carried on the housing. A first window divides the illumination compartment from the agitator cavity and a second window provides an outer facing for the illumination compartment. The light source illuminates the agitator which is viewed through the first and second windows.
