This is a dust box module for the iRobot Roomba. It's a used part from a Roomba 885 (made in 2016). The exterior is in relatively good condition, but this is just my personal opinion, so please judge based on the images provided. I've only done a basic cleaning, so please check the images and only purchase if you are satisfied. (Operation has been confirmed to be working fine with my equipment.) It can be used with almost all Roomba 800 series models (excluding 890 and 900 series). ※ Important: In the event of any defects or damage during shipping, we will be unable to provide support after you have left feedback.
