ROOMBA iRobot vacuum is in excellent condition and works great. We used it for a short time only due to it not being a good option with our blind dog. Sells for $600 and selling for $300 OBO.

RVD-Y1 refers to the Roomba i3/i4 series robotic vacuum (often sold as part of the Roomba i3+ or i4+ bundle), while ADG-N1 is the model number for the compatible Clean Base Automatic Dirt Disposal (self-emptying charging station)
