A method of removal of foreign objects from working zone of floating hydraulic dredger, at which the cleaning is carried out by submerged liquid jet of the field and by change in its direction at different angles relative to the horizon, the source of submerged jet is placed on the supporting floatation device. The submerged jet changes in the submersion depth, it is placed in parallel to aqueous surface via action on the buoyancy and stability of the supporting ship, and accumulated floating foreign objects are limited by floating protective structure and are utilized by dredged material of the field.
