Tomy Dustbot
Rating: 5/10, Surprisingly useful on a basic level. Japan’s Tomy was known for some of the best electronic toys in the ‘80s, and long before the arrival of the Roomba, it created Dustbot, which is arguably the world’s first robovac. As it randomly rolled across a desk or floor, a small pair of arms maneuvered a tiny broom back and forth, but hidden inside the bot was a vacuum with enough suction power to tackle dust, crumbs, and even confetti. It wasn’t smart, but if lunch often left your desk a mess, Dustbot would happily tidy up after you.
