Abstract
A settling tank cleaning unit includes a vertically buoyant device, provided with means to generate both horizontal and vertical propulsion, thereby moving the device in a random pattern adjacent the bottom of a tank to be cleaned and, at the same time, cutting tank-deposited solids and transporting the solids to a solids and liquid mixing propeller which vertically lifts the mixture for recirculation or to a discharge zone.
