Mint Plus Automatic Floor Cleaner, $299.99 This robotic cleaning appliance helps keep a dirt free, healthy home. On a single charge, Mint Plus provides up to 4 hours of dry sweeping (2.5 hours wet mopping) on hard surface floors. Forget your traditional mop and broom, this device uses NorthStar 2.0 technology, which acts like an indoor GPS—taking into account the amount of space it’s covered and where it still needs to go. Hence, human assistance isn’t needed. It sweeps and mops using popular cleaning clothes, such as Swiffer brand Dry and Wet Cloths and other similar products.
