TESTED iRobot Roomba Extended Life Virtual Wall Unit 400 series - $5 (Albany)
QR Code Link to This Post
* used but I received lighthouse sensors with my new Roomba so I no longer need this one
* this came with a Discovery 4210 model (Discovery series was later called the 400 series) but I tested it with a Roomba 500 & 600 series and it works as it should
* emits a harmless, invisible, infrared beam to block doorways up to 13+ feet wide that Roomba regards as a barrier and will not cross
* place it in a doorway to confine Roomba to one room, or it can be used to close off a large open area so Roomba only cleans the area you want cleaned
* requires 2 D batteries
* please view all pictures before purchase as they are part of the description
Note: I have an extra battery cover so if you have this virtual wall and just need a battery cover, let me know.
