Improved home base for iRobot Roomba. This is a repurposed home base from a Roomba i3 (2021 model). It has been used for about two and a half years. The exterior is relatively clean, but please check the images for confirmation. (Operation has been confirmed to be problem-free using my home equipment.) This is an improved home base for Roomba i-series and later models. *The rubber feet have been reinforced, making it less likely to move during docking. It can be used with almost all Roomba series models. *Important Notice: In the event of any defects or damage during shipping, we will be unable to provide support after the review is submitted. Therefore, please check the product before leaving a review. *Price adjustments are generally not available. We will gradually lower the price over time, so please purchase when the price meets your needs. We may delete inquiries about price reductions. This item is also listed on other flea market sites, so it may be removed suddenly. In the event of simultaneous purchases, the first buyer will be prioritized. If you purchase before the item is removed, we will contact you in that case. Thank you for your understanding.
