Articulated nozzle for electro-vacuum devices, which is essentially characterized by comprising two articulated parts, of which one of them consists of a hollow plate that is substantially rectangular in plan and of a variable height that is defined by a convex contour that is it is limited by a neck whose inner profile, in arc of circle, is of radio coincident with that of a cylindrical half-roller established in the frustoconical end of a tubular sleeve that constitutes the second element of the vacuum cleaner, the articulated joint being conditioned of both parts according to a uniform and invariable plane perpendicular to the geometric axis of said semi-roller, by means of the corresponding fixation to the base of the hollow plate, of a piece that at the same time carries the opportune toothing that is aligned parallel to a mouth of aspiration.
