If you have a hectic work routine but you cannot just handle a messy room, this is exactly what you need. iRobot Braava 320 can sweep your floors, whenever you want to make your bedroom, living room or the bathroom amazingly tidy. The most interesting thing about this device is that all you have to do is simply attach a piece of disposable cloth with the machine and press either the sweep or mop button. The device works on an indoor GPS system called North Star Navigation System, which can dry sweep around 800 square feet in one go while during mopping it covers up to 250 square feet in one cycle. When you are done cleaning you need to throw away the cleaning cloth and wash the microfiber cloth provided with the device for later use.
