Purchased new in 2018 as a discontinued model. The battery was replaced about 3 years ago. Includes the main unit, remote control, Auto Virtual Wall (2), Home Base, and instruction manual. While there are no operational issues, it's not in pristine condition due to unavoidable dirt and scratches. Also, the edge-cleaning brush is quite worn, so please replace it if necessary (it still picks up some debris even without it). The dust cut filter has been replaced with a new one. Please understand that this is a used item before ordering. iRobot Product Name: Roomba
