PRODUCT OVERVIEWKeeping your floors clean is easier than ever with Mint Automatic Floor Cleaners. Just attach a disposable cleaning cloth, set Mint down, press either the Sweep or Mop button and let it clean. After cleaning, simply dispose of the cleaning cloth or wash the included microfiber cloths for use later. Mint includes disposable cleaning cloths that make cleaning up a breeze. Simply attach the cloth then throw it out once Mint is finished. When dry sweeping, Mint can cover up to 800 square feet in a single cleaning cycle. When mopping, Mint cleans up to 250 square feet to focus on a smaller area while the cloth is still wet. NorthStar Navigation System works like an indoor GPS by projecting a signal that it uses to determine, and later map, its location in your room. When Mint starts cleaning, it uses NorthStar to build a map of the area as it goes, marking walls, obstacles and drop-offs as it encounters them so it can clean more efficiently with each cleaning. NorthStar Navigation keeps track of where Mint has cleaned and where it still needs to go, so you can be sure it"s thoroughly covered your entire floor PerfectEdge technology allows Mint to clean dust and dirt right along walls, baseboards and edges. Its square shape allows Mint to clean dirt and dust hiding in corners that you might miss Whisper-quiet operation; turns itself off when finished Low maintenance with no bins to empty or filters to change MFG Model # : iRobot Mint 4205 MFG Part # : R4200
