Used for 1210 hours, this is a Roomba Combo J9+ (2023 model). It's making unusual noises and vibrations, possibly due to the extensive use. *It still cleans without issue. The included parts are only those shown in the images; there are no instruction manuals, warranties, or original packaging. The app has been reset, so you can use it immediately. The battery runs for about 30 minutes without any problems. (However, please understand that battery performance can vary depending on the environment, so we cannot guarantee it.) Condition: In addition to the aforementioned noises and vibrations, there are many scratches on the bumper and top, so it is being offered at a low price. The app usage time is as displayed, but it has been used for a few more hours for various operational checks, so please be aware that the total time is slightly higher. However, the appearance is based on a personal assessment, so please judge based on the images. ■Important: Please be sure to check the operation before leaving feedback. We will not be able to process cancellations if there are any issues, as it will be difficult to determine whether the cause is due to us or the shipping process. *We generally do not offer discounts. We will gradually lower the price depending on the timing, so if the price doesn't meet your expectations, please purchase it when the price drops. We may delete inquiries about discounts. It is also listed on other flea market sites, so it may be removed suddenly, or in the case of simultaneous purchases, the first buyer will be given priority. In such cases, we will contact you if you have purchased it before it was removed, so please understand.
