The iRobot Roomba series of vacuum cleaners revolutionized the way people vacuumed, making it more of a passive chore than an active necessity. The automated robotic vacuum allows people to schedule their vacuuming as it's convenient for them and ensures a clean floor upon return home from work or a day out. The newest vacuums in the iRobot line are the 500 series, with the pinnacle being the 570. The 570 features an array of options for your cleaning needs, although the features may not be enough to warrant an upgrade from your previous Roomba vacuum. The biggest enhancement has been the addition of a wireless command center so that you can control where your Roomba is vacuuming. The addition of 2 virtual walls forces the Roomba into an imaginary enclosed area so that you can ensure an extra-clean floor. Weight: 12.5 lbs.
