Today only, this Neato Robotics XV-12 Vacuum System, once $399.99, is now $299 at Target.com. With free shipping, this is the best deal we could find by $100! It features room-mapping technology to determine the placement of everything in the room, and then it vacuums around all objects without bumping into anything. It requires one button to operate, and it returns to its charger base when it is done vacuuming. Sales tax is charged in most states.
