With everything that people have to do today, it's hard to find time to clean your living quarters. That's why miniature robot cleaning devices like the Roomba are such a hit. Just turn it on, and watch as it cleans your floors, as you continue to do whatever it is you need to do. Timers help, too. But, up until now cleaning your windows was something you had to take time out of your day to do. Not anymore, thanks to PIRO's Windoro, which fastens to your windows, and cleans them just like the Roomba cleans your floors.
