Roomba isn’t the only robotic cleaning device on the scene now. The new Mint automatic floor cleaner is designed specifically for hard surfaces like wood and linoleum and uses most popular disposable cleaning cloths (Swiffer) and re-usable microfiber cloths for dry sweeping and wet mopping floors. The square shape allows it to reach all the way into corners. It uses the NorthStar System that works like an indoor GPS, with the NorthStar Cube emitting a signal that Mint uses to determine its location. Then Mint builds a map of the area as it cleans, marking walls, obstacles and drop offs as it encounters them. It’s available from Hammacher Schlemmer for $249.95.
