This is a junk item. Used for six months. In good condition. Purchased at the end of 2024. A rider error occurs one meter from the station (sensor). It seems that it can be improved by cleaning such as paper jams, but it does not improve even if cleaned easily from the outside. It seems that it may be improved by removing and cleaning the inside, but I don't have the courage to disassemble this type of product, so I'm selling it as is (undisassembled). Please consider this for parts or if you are knowledgeable. Since this is a junk item, I don't know what other problems there may be. Please understand that we cannot accept claims or returns. ★EUREKA J12Ultra Robot Vacuum Cleaner 5000pa Powerful Suction, Fully Automatic Station, Wet and Dry Cleaning, Automatic Dust Collection, Automatic Mop Washing and Drying DuoDetect AI™ 3D Object Identification Technology Enhanced Obstacle Avoidance, High-Precision Mapping, Quiet Operation, App Control, Alexa Voice Compatibility nerj12ultra ❶【Fully Automatic Dust Collection, Mop Washing and Drying】 The Eureka J12 Ultra robot vacuum cleaner is equipped with an all-in-one station, fully automating automatic dust collection, automatic mop washing and drying, clean water replenishment, and wastewater collection.
