A device for cleaning and degassing underground storage tanks is constituted by an entirely pneumatically or hydraulically powered motorized vehicle, which can be placed internally of a tank to be cleaned and be moved around inside the tank itself, for example by means of tracked wheels driven by respective pneumatic or hydraulic motors. Said motorized vehicle may be provided with a first series of nozzles, frontally arranged with respect to the advancement direction of the vehicle, which nozzles emit water at high pressure with the aim of breaking up and suspending in the water the deposits collected in the tank; the vehicle is also provided with a suction mouth arranged anteriorly of the first series of nozzles, by means of which mouth the water-suspended deposits are aspirated and removed from the tank. |
