Dust bin for Roomba J7 (2023 model), used for about 2 years. I cleaned it, but some dust might remain. Please purchase only if you understand that it is a used item. Basically, please refrain from price negotiations. I will gradually lower the price over time, so please purchase when you are ready. I am also selling on other flea market apps, so it may disappear suddenly, or if multiple people purchase at the same time, the first person to purchase will be given priority. Thank you for your understanding.
