Vacuum cleaner assembly to be supported by a vehicle and vehicle equipped with this assembly

The cleaning unit is mounted on the back of a light vehicle and uses a tank (2) to store collected waste, the tank having a tapered outlet (3) at the bottom to allow it to be emptied. In the working position a mechanism (4) positions the tank over the back wheels of the vehicle, but to empty the tank a hydraulic actuator (7) tilts an arm (6A) so the tank projects beyond the back of the vehicle.
