Accessories for the iRobot Roomba. I purchased these used on Mercari, but no longer need them as I've replaced the main unit. This listing is for a set of 5, but I'm also open to selling them individually. Please let me know in the comments if you're interested. I'm also selling a remote control at the same time. I will ship anonymously via Mercari delivery. Thank you. ● Roomba Room Navigator for 885/880/780/577/570 models This is a convenient optional accessory with a Virtual Wall function that allows you to set the Roomba's operating area, and a Lighthouse function that guides the Roomba when cleaning multiple consecutive rooms. Thank you for looking.
