A walk-behind unit for small jobs

The semi-automated Vortex™is ideal for smaller marking removal jobs that cannot justify complete systems but are too big for manual water jetting. These easy-to-handle units utilize NLB’s patented SPIN JET®technology at 40,000 psi (2,800 bar) pressure, with vacuum recovery.


Maneuverable, low-maintenance and ergonomically designed, these hardworking units are used on everything from ship decks to parking lots.
