iRobot Roomba 500 Series Main Unit Set 537 Robot Vacuum Cleaner Roomba 537 (Japanese Domestic Genuine Product) Station Instruction Manual Included It was in regular use until just recently, and there were no major problems with its movement. It charges and operates, but it feels somewhat unstable, so I would consider it a junk item. "Remote Control" and "Virtual Wall" are new, unused, and genuine products. Compatible filters are also listed separately. If you need them, I will change the price and include them. It's stylish, with the "classic Roomba" design from the early days, and I think it looks great just by placing it. Please understand the age-related dirt, discoloration, and dust that couldn't be completely removed despite cleaning. ・Basic Specifications Type: Robot Maximum Operating Time/Continuous Use Time: Up to 60 minutes Charging Time: 3 hours ・Size/Weight Body Dimensions (Width x Height x Depth): 340 x 92 x 340 mm ※ This item is a junk item, so its operation is not guaranteed. ※ For safety during transportation, the battery will be removed and shipped separately, so it will not be included. ※ The brushes are compatible products.
