iRobotRoomba Authentic Replacement Parts - Dual Mode Virtual Wall Barrier (2-Pack)

Works great

I bought these sensors for my iRobot. They work great at keeping my iRobot from entering certain areas. Great product and great price. I would recommend it for anyone that needs to control the IRobot movements

It does a awesome Job ,What I like is it goes back to is charging station on it own too recharge it selfAWESOME

El producto funciona con una Roomba modelo 671, delimita el paso ya sea en el switch hacia arriba en linea recta y hacia abajo en un area circular, usa dos baterías AA incluidas, lo que me parece excesivo es el costo son unas mini cositas de menos de 10 cm. de altura y no pesan nada. Por el precio esperaba algo mas robusto, deberían costar menos de la mitad y eso que las conseguí en una promoción. Si son muy útiles.

I have bot been able to set my IRobot for individual rooms yet. But I gave a very large living/dining room (open floor plan). The doorway to my family room is a 10 foot archway and one of these effectively blocked it so the roomba remained where i wanted it. Also, there us a 6 foot doorway into my kitchen. Same thing. They are little but they are mighty. Great product.
