A suctioning device for suctioning a water volume from a bottom of large artificial water bodies, with surfaces larger than 10,000 m 2, without centralized filtration systems, where the suctioning device is capable of cleaning at a surface rate of 325,000 ft 2 per 24 hours (30,000 m 2 per 24 hours) or more, the device comprising: - a flexible sheet configured to provide a structural frame for attaching or affixing the different pieces and parts of the suctioning device; - a plurality of first brushes depending from the sheet; - a plurality of middle brushes configured to redirect the bottom water flow into the first brushes; - a plurality of lateral brushes configured to contain the bottom water flow within the suctioning device and avoid the re-suspension of the bottom water flow in the vicinity of the suctioning device; - a plurality of suction points configured to concentrate suction capacity to increase suction power in the suction points; - a plurality of safety wheels configured to provide secondary support and avoid damage to the suctioning device when the first brushes, the middle brushes, and/or the lateral brushes are worn out and cannot provide a proper support or suction height of the suctioning device; - a plurality of collectors configured to gather the suctioned bottom water flow and concentrate the suctioned bottom water flow into one or more external suction lines; - a plurality of internal suction lines configured to conduit the suctioned bottom water flow from the plurality of suction points to the plurality of collectors; and - a coupling device connecting the internal suction lines and the collectors, wherein a rate of the bottom water flow entering the suctioning device is the same or higher than a rate of water flow suctioned by an external pumping system. - a flexible sheet configured to provide a structural frame for attaching or affixing the different pieces and parts of the suctioning device; - a plurality of first brushes depending from the sheet; - a plurality of middle brushes configured to redirect the bottom water flow into the first brushes; - a plurality of lateral brushes configured to contain the bottom water flow within the suctioning device and avoid the re-suspension of the bottom water flow in the vicinity of the suctioning device; - a plurality of suction points configured to concentrate suction capacity to increase suction power in the suction points; - a plurality of safety wheels configured to provide secondary support and avoid damage to the suctioning device when the first brushes, the middle brushes, and/or the lateral brushes are worn out and cannot provide a proper support or suction height of the suctioning device; - a plurality of collectors configured to gather the suctioned bottom water flow and concentrate the suctioned bottom water flow into one or more external suction lines; - a plurality of internal suction lines configured to conduit the suctioned bottom water flow from the plurality of suction points to the plurality of collectors; and - a coupling device connecting the internal suction lines and the collectors, wherein a rate of the bottom water flow entering the suctioning device is the same or higher than a rate of water flow suctioned by an external pumping system.
