This is a home base for the iRobot Roomba. It is a repurposed item from a Roomba 640 series (made in 2016). It has been used for approximately 5-8 years. Please check the appearance in the images and make your judgment. (Operation has been confirmed to be problem-free using my home equipment.) Although it is an older type, it can be used with almost all Roomba series. ※Request In the event of any defects or damage during shipping, we cannot provide support after the evaluation.
