A cab (5) of a truck has an exterior mirror (2) equipped with a pneumatic mirror cleaning device (1) for the mirror's surface (24). The pneumatic mirror cleaning device (1) includes a source of pressurized gas comprising an on-board air supply system commonly employed in trucks. A nozzle element (22) is mounted nearby the mirror (2) for directing a stream of pressurized gas against the surface (24) of the mirror (2). A line (26a) connects the nozzle element (22) to the source of pressurized gas, and a control valve (30) in the line (26a) is manually moveable between an open position which places the source of pressurized gas in communication with the nozzle element (22) to provide the stream of pressurized gas against the surface (24) of the mirror (2) and closed position to discontinue the stream of pressurized gas. |
