AIR U+ Dual Mode Virtual Wall Barrier Compatible with iRobot Roomba 500/600/700/800/900/e/i/s Scooba 400 Series Robots, 2Pack

Works great

Does what it advertises.

Work just as expected, no set up, just add batteries and you're good

I’m happy I purchase these and they were great with my i series Roomba. Of course with a j series, they do not work for. With the j, you actually have to map out your room and block everything that you don’t want it to go to. But with that earlier series this was perfect. I didn’t see any reason to spend the extra cost for an iRobot item and so I was very happy that I was able buy two of these for the price of one of theirs. I’ve had them running now for four months and they are working great.

Keeps Roomba out of trouble
