AX EV: World’s First Cardboard Vacuum Cleaner – a high performance vacuum cleaner constructed for optimum sustainability, using recycled and recyclable materials. Made out of cardboard, the machine is a fully functioning prototype vacuum cleaner, but that could also be recycled at the end of its life. The corrugated cardboard panels that form the body of the Vax ev are easily replaced if damaged and cost just a tenth of the price of an equivalent plastic panel.
