How much time do you usually spend each week vacuuming your house? That's time that could be spent on other chores or with your family. Now you can vacuum without even being in the room! The Roomba will vacuum every room of your house, regardless of the surface! The Roomba robotic floor vac is easy to use, but under the hood it's a complex robot featuring a high-efficiency particle vacuum and cleaning brushes that provide exceptional surface cleaning. It may be circular, but the Roomba still cleans edges and corners using its spinning side brush, which rotates outside the unit's housing diameter to gather debris from tough-to-reach spots, cleaning right up to the wall.
