Thank you for viewing. My parents used this a few times in their bedroom. They don't smoke, and they don't have any pets. Everything is included except for the original box, such as the instruction manual, the main unit, and the charger. There are a few scratches on the power cable, but I don't think it will affect its use. Please consider this item if you understand that it is a used item.
