ABSTRACT In order to be able to detect leaks in gas mains that are laid under streets and roads in a more economical manner, and yet more frequently, it is proposed that in a motor vehicle that is used for street cleaning operations and having a vacuum pickup system for dust or dirt, which comprises a suction head that glides over the surface of the road, a dirt collection container and an exhaust air system, the vehicle also carries a gas detector, consisting essentially of a gas analyser and indicator, a gas or power supply system and a gas pump, being arranged in a familiar manner within the driver's cab of said vehicle. A suction device for gases is arranged outside the vehicle in the vicinity of the road surface, by means of which the flow of gas that is to be analysed can be passed to a detector device, for example, a probe or a diffusion head.
