The WMF Lumero achieves its purist appearance with geometric shapes and a housing of high-quality matte and polished stainless steel. When the machine is switched on, a surrounding LED ring integrated in the base visually elevates it from the worktop. The oval-shaped main body features an intuitive touch-screen user interface inclined at 45 degrees, facilitating ergonomic control of the machine from the front as well as from the side.
