The Roomba 620 by iRobot offers a great discount since it’s not the newest model, but still remains very powerful and versatile (can clean your carpets and hard floors with seamless transitions). Very easy to use out of the box, with a big “Clean” button that can be pushed to activate. Your Roomba 620 will then go around the room, cleaning with fast moving bristles and intense suction for other debris (surprisingly quiet). Infrared mapping technology allows it to “learn” the surrounding areas and clean more efficiently – although it may look sporadic it will cover every spot, and since it’s automated there is no rush.

Reviewed and praised by many, the Roomba 620 is a great bargain robot vacuum cleaner that gets the job done with a long battery life, cushioned polymer (to protect it and your walls), and patented bristle / suction technology.
