Thank you for viewing. [New & Unopened] "Roomba® Max 705 Vac Robot + AutoEmpty™ Charging Station" I received this as a housewarming gift, but my house isn't that big, and I don't really need a robot vacuum, so I'm listing it on Mercari. There is no documentation with the purchase date, as it was a gift. Please see the following URL for product details: https://www.irobot-jp.com/roomba/705/ I am a non-smoker and do not own any pets. To avoid any unnecessary trouble, I will decline purchases from users with poor ratings. I will review the buyer's rating after purchase and may cancel the transaction. Please be aware of this. Also, to prevent any product substitution, I have recorded the serial number on the box. I will delete this information after the transaction is complete. I will ship the item within 24 hours of your order, if possible. Thank you for your consideration. iRobot Product Name: Roomba
