Prodis EV50S, 500mm Heavy Duty Electronic Glass Washer, Automatic Water Softener, Drain Pump

This particular one is the EV50S, Glass Washer, Automatic Water Softener, Pump. It's specified with a 575mm width and a 2-year parts-only warranty. It's part of Prodis's heavy-duty electronic range, built for daily commercial use rather than light domestic-style washing. Drain pump versus gravity drain really comes down to what your existing plumbing already supports. Worth checking your incoming water supply against the model's softener or filtration setup before installing.
