This is the Kyvol robot vacuum cleaner, model E20! The retail price was about 17,000 yen. You can buy a robot vacuum cleaner at this price, so it's perfect for your first try. It has only been used about 5 times! It also comes with a remote control! By installing the Kyvol app, you can manage it with your smartphone, and you can customize it to your liking by operating it from your smartphone and scheduling tasks! Regarding the common problem with robot vacuums, such as Roomba, where they can't clean corners, this product has an "edge mode" that thoroughly cleans gaps and corners! I think this is a Roomba that you will definitely be satisfied with! To prevent "return substitution fraud," which has been in the news recently on Mercari, we are asking for 3N (no returns, no refunds, no exchanges). Thank you for your understanding. Thank you!
