This is a home base for the iRobot Roomba. It is a repurposed item from the Roomba 640 series (made in 2015). It has been used for approximately 5-8 years. Please check the appearance in the images to 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 models. *Important Notice* In the event of any defects or damage during shipping, we are unable to provide support after the review is submitted. Therefore, please be sure to check the product before leaving a review. *Regarding Price* We generally do not offer discounts. We will gradually lower the price over time, so if the current price doesn't meet your needs, please wait for the price to drop. We may delete inquiries about discounts. We are also selling on other flea market sites, so the item may be removed suddenly. In the case of simultaneous purchases, we will prioritize the first buyer. If you purchase before the item is removed, we will contact you in that case. Thank you for your understanding.
