Nio is a fully automatic coffee maker which was designed for use in office environments or for catering. Thanks to a keyless cleaning and operating function, filling, cleaning and emptying is easily possible from the outside, without the need to open the machine. The transparent containers for ingredients, accessible from the top, are a visible confirmation that each coffee specialty is made fresh, while at the same time facilitate easy filling. The colored LEDs are not only lively but also support the easy use and operation of the Nio.
