Abstract: A vacuum cleaner main chassis incorporates a light plate for providing light from a relatively narrow slot extending across the front of the chassis onto a floor surface to be cleaned. The light plate is generally planar and transmits light therethrough within its plane from an input edge of the plate to an opposite output edge thereof. The plate output edge resides in the chassis front slot while the rest of the plate is enclosed within the chassis so that light emerges from the chassis only through its front slot. The slot is relatively close to the floor surface for illuminating an area thereof beginning relatively adjacent the chassis. Lamps located adjacent the relatively rearward input edge of the light plate are thus positioned relatively remote from a suction nozzle and rotatable bar brush located in a forward area of the chassis, which avoids preempting critical space in such area or interfering with operation of such elements.
