iRobot Roomba s9+ (manufactured December 2020) Number of uses: 547 Total usage time: 226 hours 20 minutes Number of times garbage detected: 21 Number of times automatic garbage disposal: 512 Operation confirmed, no problems. I also confirmed that it returned to the Clean Base, disposed of the garbage, and started charging after cleaning. I removed the parts and washed the washable components, wiped the non-washable components with disinfectant sheets, and removed dust with an air compressor. For hygiene reasons, a brand new, unused genuine filter will be installed and sent. It is a beautiful item with no scratches. Accessories Clean Base (charger) AC cord Paper bags x 2 (genuine) Instruction manual set Since there is no original box, it will be carefully packed and shipped in a new cardboard box. Thank you very much.
