FIELD: excavation and moving of soil.SUBSTANCE: invention is based on the task of developing a device that systematically collects the soil of a reservoir, sucks it in layers and passes through it even in case of major obstacles. According to the invention, the task is solved due to the fact that the controlled floating body is equipped with at least one pump/compressor and at least one hydraulic unit, as well as at least one generator unit and through pipelines connected on the one hand to the alluvial platform, or to the settling basin, or to the transported reservoir on the shore, on the other hand, with a suction module, which independently moves along the reservoir ground using a special tracked undercarriage, is connected via cable to an echo-sounder sensor and/or GPS receiver located in a floating way on the surface of the reservoir above the suction module, and/or in front of them, and/or behind them has a freely swinging, one-, or two- or multi-lever swivel lever, which also independently adjusts to
