Used for approximately 3 years, 470 hours. This is a maintenance parts set for a Roomba i3 (purchased in January 2023). The instruction manual, original box, etc. are missing. The included items are only those shown in the images, and there is no warranty. The app has also been reset, so you can use it immediately. The battery runs for about 30 minutes without any problems. (However, please understand that the battery performance may vary depending on the surrounding environment, so we cannot guarantee it.) Condition: As a vacuum cleaner, the Roomba has scratches on the bumper and top, but it has been used relatively little, so I feel it is in relatively good condition. The usage time displayed in the app is the actual time, but it has been used for a few more hours for various operational checks, so please understand that the total time is slightly increased. However, the appearance is based on my personal opinion, so please judge based on the images. ■Request: Please evaluate after confirming the operation. If there are any problems, we will not be able to determine whether it is due to our fault or a problem during shipping, so we will not be able to cancel the order. ※Basically, we do not offer discounts. We will gradually lower the price depending on the timing, so if the price does not meet your expectations, please purchase it when the price is lowered. We may delete inquiries about discounts. We are also listing this item on other flea market sites, so it may be removed suddenly, or in the case of simultaneous purchases, we will prioritize the buyer who purchased it first. In that case, we will contact you if your purchase is canceled before the item is removed, so please understand.
