iRobot Roomba 880 Vacuum Cleaner

Selling an iRobot Roomba 880. It comes with the charging dock and 2 lighthouses. It does have some signs of use, but is in good working condition. Unfortunately it isn't running more than 20 minutes right now, I believe it needs a new battery. You can get them from IRomba or Amazon. I have a small apartment now I just don't need it. The Roomba 880 features the AeroForce Performance Cleaning System.
