Used for approximately 15 hours! Roomba Plus 405 Combo, complete with original packaging. Includes: Main unit, Home Base, paper bags, spare mop, and spare brush set. *Dedicated instruction manual is missing. The app has also been reset, so you can use it right away. The battery runs for about 60 minutes without any problems. (However, please understand that the battery life may vary depending on the surrounding environment, and we cannot guarantee it.) Condition: This unit was used as a sample in a model room for six months, so usage is low. However, it has some scratches on the top, etc., from removal. The dedicated power cord is missing, so a generic cord is included. Thank you for your understanding. *Please note that the operating time may increase due to operational checks performed before shipping.
