Prodis EV50G, 500mm Heavy Duty Electronic Glass Washer, Gravity Drain

This particular one is the EV50G, Glass Washer, Gravity. It's part of Prodis's heavy-duty electronic range, built for daily commercial use rather than light domestic-style washing. Worth checking your incoming water supply against the model's softener or filtration setup before installing. Drain pump versus gravity drain really comes down to what your existing plumbing already supports. It's specified with a 575mm width and a 2-year parts-only warranty.
