This is an ECOVACS DEEBOT. It appears to be in good condition with no noticeable scratches or stains, but it is being sold as junk due to a parts defect. An error message "D-TOF sensor stopped. Please tap lightly" is displayed. Tapping does not resolve the error, so I purchased a new one. It seems that the issue can be fixed by cleaning the sensor, replacing parts, or updating the firmware, but I cannot guarantee this, so please consider it as junk. The charging/cleaning dock and other functions and parts were working normally, so I think it can be used for parts. The charging dock can apparently be used with other T10 Omni models, so it might be good for those who use it in multiple rooms. Please check the exact specifications with the manufacturer. Please understand that this is being sold as junk.
