Keeping your floors clean is easier than ever with Mint Automatic Floor Cleaners. Just attach a disposable cleaning cloth or the unique Reservoir Pad with a Pro-Clean microfiber 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 a detachable Reservoir Pad that fills and empties easily over the sink. To use, pour in water or mild solution, close the fill cap, attach a damp Pro-Clean microfiber cloth and place the Reservoir Pad back on Mint. In dry sweeping mode, Mint Plus can sweep for up to four hours or mop for up to two and half hours on a single charge that’s 25% more cleaning time than the Mint 4200 or 4205.
