Purchased in 2013 for 60,000 yen. During the long warranty period, it was repaired twice due to rattling noises. The cleaning brush has been replaced several times. The battery has been replaced once. It still works without any problems. There were times when the home base moved and the Roomba couldn't return properly, so I secured the bottom of the home base to the floor with double-sided tape. I've removed all the double-sided tape and cleaned it. When listing it on Mercari, I called iRobot and had them delete my personal information. They said they would still keep the product information itself (product number, number of repairs, etc.) at iRobot. I disassembled and cleaned it as much as possible, but please understand that it has been used for many years. The Virtual Wall is unused. Included Accessories: Roomba main unit Remote control AC adapter and power cord Home base 2 Auto Virtual Walls I will include new ones separately: 2 Cleaning brushes 2 Filters Instruction manual iRobot Product Name: Roomba I am also listing a Roomba 780.
