Purchased in 2013 for 60,000 yen. The cleaning brush has been replaced several times. Sometimes the touch panel doesn't work properly. Two screws on the back are also missing, so I'm listing it as junk, but it works without any problems. The battery has never been replaced. There were times when the home base moved and the Roomba couldn't return properly, so I had fixed 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 I tried to contact iRobot to delete my personal information for the Mercari listing, I found I wasn't registered. However, the product information itself seems to remain with 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 items: Roomba body Remote control AC adapter and power cord Home base 2 Auto Virtual Walls Instruction manual I will include new ones separately. 2 cleaning brushes 2 filters iRobot Product Name: Roomba
