Review on 🤖 Enhance Roomba Performance with Authentic iRobot Dual Mode Virtual Wall Barrier (2 Pack) - Compatible with Roomba 600/700/800/900/e/i/s Series Robots by Tom Bailey

I used these virtual barriers for the first time today and they definitely work. Installing the battery was easy. The instruction consisted of two mediocre pictograms. But the gadgets are pretty basic, so it's no big deal: a three-position switch; The middle position is off, the top position is round barrier mode, and the bottom position is wall barrier mode. Turn it on and the little bar will flash a few times and you're good to go.
