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

Very helpful! Love these little machines. I wanted to make sure I got Roomba brand because I worried that if I tried to save a penny by going with a similar functioning item, but by another brand, that they wouldn't communicate well. So, these work great! There is no noise that comes from these. They're sturdy! I do remove the batteries in between uses (no clue if that actually prolongs battery life). But when I pop the batteries back in, they work wonderfully. I get confused on which they need to point in order to speak with my Roomba, but that's a simple fix - just turn them the other way. :) I'm sure the manual notes that, but I was too excited to use them once they arrived. I feel like these things are small but mighty. They have 2 modes; and I have used both and apprecate them equally. I like that they take batteries rather than charge - not sure if others feel the same. They do a really great job of blocking off spaces that I don't want Roomba to go. Pros: price matches quality; easy to use; needs batteries; 2 modes; small but mightly; unobtrusive; compatible with my Roomba Cons: needs batteries

Last year we bought a Roomba i4 which came with one virtual wall. The Roomba works great and the wall barrier is handy to block off a section of hallway or a door that doesn't quite close properly. But with Christmas here one barrier isn't really enough to protect the Christmas tree and the presents under it. So we ordered two more. So far they work great. They will also be really useful when we want to vacuum just the kitchen (which has two entrances) or block off larger areas of the house. I also liked that these came with batteries, so that I could use them as soon as I got them. Overall I am really happy I ordered these.

It works very well. I used to block off areas where I didn’t want Rhoomba to go with this little item it is easy. Just set up as in instructions and mission accomplished. So easy.
