A stripping system employing an end-effector with a nozzle and at least one brush circumferentially disposed around that nozzle, and a vacuum device for creating a vacuum between the nozzle and the brush, can remove substances from a substrate with such complete effluent recovery so as to prevent flash rusting of the substrate. The nozzle has orifices, bores, and a plenum chamber such that the plenum chamber is sufficiently large to maintain the desired pressure and amount of liquid to the orifices, the bores have a sufficient length to orient the liquid flowing therethrough in a laminar flow upon reaching the orifices, and the orifices are sized and oriented on the nozzle face in order to produce an even energy profile when the liquid strikes the substrate. The brush has sufficient tuft density and bristle stiffness to allow make-up air into the vacuum while preventing the escape of effluent.

A stripping system for removing substances from a surface comprising: an end-effector having a nozzle, a first brush circumferentially disposed around said nozzle at a sufficient distance from said nozzle to allow the formation of a vacuum therebetween, an additional brush spaced from said first brush, wherein each of said brushes has bristles arranged in tufts of at least one bristle and has sufficient tuft density to prevent the escape of effluent from the end-effector, a liquid supply connected to said nozzle; and a vacuum chamber disposed about said nozzle, said vacuum chamber enclosing a vacuum created by a vacuum device connected to said vacuum chamber, said vacuum being sufficient to recover effluent, wherein said first brush assists in directing the effluent into the vacuum chamber and said additional brush acts to capture any effluent which may escape through the first brush, said brush arrangement and the vacuum formed between said nozzle and said brush being sufficient to substantially completely remove the effluent from the surface.
