nello Pet Dry Room PD-B10-P, Cleaned, with Instruction Manual Only the main unit and instruction manual are included. The original box is not included. The power cord is marked with "2023," so I believe it's a 2023 model. Operation has been confirmed. Overall, there are scratches from use. There are many scratches, especially on the transparent door. It's difficult to see the extent of the scratches, but please refer to the photos. The door seems a bit stiff to open and close, but it's unclear if this is normal. Following the instructions, I disassembled the removable parts and washed them thoroughly with water and a brush. The main unit (which is not washable) and the dust filter were cleaned by wiping them down. I re-confirmed the operation after reassembly. I have cleaned it to the point where it can be used immediately upon arrival, but this is a DIY cleaning, so please refrain from purchasing if you are looking for perfect cleaning.
