iRobot® Dual Mode Virtual Wall® Barrier (Set of 2)

I recently purchased these as the ones that came with my original machine stopped working. The old ones covered larger distances than these new ones. I still have an old one that works so I use that and have to use the two that I bought together to cover the distance of my rooms. They work well just not for where I need them.

I use it to create a barrier around my cats' food and water dishes. Works perfectly.

Thank you to those that aren't tech savy. I found my two units at the Goodwill for $4. Replaced batteries and they work as advertised. The straight wall settings have an offset of about 12" from expected line.

I purchased a package of two. Neither work. I've replaced the batteries. The light blinks three times and the roomba just knocks it over.

Bought four in Apr 2019. Work perfectly. No battery replacement yet.

Daily use for all areas of the house.

Love my virtual walls! Have 3 of these and looking to buy another! They work great. They keep my roomba exactly where I want her, and keeps her from venturing where I don't. I don't understand these bad reviews. Make sure your roomba is compatible. Take out of the package and set either straight line wall or halo wall. Excellent product!

Great product for your IRobot Roomba. Let’s you block off areas or determine restricted areas to vacuum. Sure you can shut doors, sometimes, but with these you can leave door open and still restrict Roomba to certain rooms. Works wonderfully.
