Cleaning apparatus comprising at least one suction device of a fluid toward the inside of the apparatus connected to an external suction duct and means, interposed between said duct and said suction device, for holding back the solid particles present in the fluid. Such means for holding back the solid particles comprise at least one mixing chamber containing in part the liquid and means for causing turbulence in this mixing chamber in such a way as to create a saturated environment of liquid in suspension above the free surface of the liquid contained in the mixing chamber.
