ABSTRACT:
An illuminated belt view for a vacuum cleaner wherein light is transmitted, via a light pipe, from a remote light source to an area directly underneath a transparent belt view window. The transparent belt view window is formed in the vacuum cleaner hood to allow the operator to observe the operating condition of the belt therein, the belt being operable to transfer rotational motion from a motor output shaft to a rotary brush. Illumination of the belt in the area of the belt view window allows the belt and the operating condition thereof to be observed during low ambient light conditions. Use of light from the light source, which is primarily a headlight, removes the need for an independent light source for the belt view window without significantly decreasing the amount of light which is transmitted to the area in front of the machine. Also, use of a single light source for indicator illumination and headlight functions reduces the energy necessary to operate the vacuum cleaner, the heat produced by the vacuum cleaner, and manufacturing and maintenance costs by minimizing the number of light bulbs to be installed and replaced.
