Clean Up Summer With a Self-Driving Roomba for Your Pool
Having a pool is fun. Cleaning it by dragging a net around is not. That's why I've thought up the Moobi, a water-loving take on the Roomba vacuum cleaner. Like a whale, the Moobi use an oscillating tail, wagging up and down, to move through the water. And like a whale, it would live its life with its mouth wide open, sucking down water and filtering out waste as if it were tasty plankton.
