iRobot Roomba Vacs - Model 564/650 (New Market, Md Lake Linganore)

Offering 2 iRobot Roomba vacs, one Model 564 Pet Series and one Model 650. Both are well used, but do charge and operate. They could both use replacement filter and brush sets, and one probably could use battery replacement. But parts are readily available via Amazon and they both do operate and charge. If interested in one or both please suggest day/time for pickup.
