Abstract
A wide-area vacuum nozzle includes a body having a first surface, a second surface, a leading edge, and a trailing edge, where the leading edge and trailing edge form an outer periphery of the body. The outer periphery includes a first juncture and a second juncture disposed between the leading edge and the trailing edge. An aperture formed through the first surface and second surface of the body is disposed between the leading edge and the trailing edge. A fitting is connected to the aperture and adapted for connection to vacuum source. The leading edge forms an arc extending between the first juncture and the second juncture.
