I purchased this item last year and used it for one year. I have carefully cleaned and disinfected it before listing it. I have also confirmed that it works without any problems. The exterior appears to be free of noticeable scratches, but there are faint marks from the rubber rubbing (in my personal opinion) due to the rotating parts. There are traces of cat litter inside (please refer to the photos). I have also used the PURE MAX2, and from the owner's perspective, this was just as convenient. Wi-Fi connection is supported. You can monitor the number of times your cat eliminates waste, its weight, and manage its health using the centimeter sensor. *The manufacturer's warranty has already expired, so we cannot provide support in the event of any defects. Please understand this before purchasing. The only included accessory is the power cord. *Consumables such as cat litter and filters are not included for hygiene reasons. Please prepare them yourself as needed. Shipping will be via Kuroneko Yamato cash on delivery. Direct transactions are also possible. Please check the photos for the condition and only purchase if you are satisfied. Please refrain from purchasing if you are sensitive to used items. Thank you for your consideration.
