If you haven't figured out how to clean your floor robotically by now, you might be a lost cause, but Evolution Robotics is willing to give it a try with its new Mint machine. The bot uses regular Swiffer pads, and is designed for cleaning hard floors with a shove of the wet-nap. Outside of its lack of vacuum, the Mint also differentiates itself with its "NorthStar" positioning tech, which lets the bot keep track of its exact location with GPS-style tech, relative to a base station, ensuring that it hits every spot and doesn't waste time with random meandering. Mint should hit retail in Q4 of this year for under $250. Check out a video of it in action after the break.
