Abstract
Methods and apparatus are disclosed for cleaning storage containers used in petrochemical or oil refineries. A remotely controllable dual tracked robotic vehicle is placed in a container to be cleaned. A cleaning fluid diluent material is directed against waste material in the container causing a portion of it to form a slurry which is vacuumed out by a nozzle and hose carried by the vehicle. A separator system exterior to the tank processes the removed slurry.
