Give your Roomba an additional virtual wall. The Virtual Wall Unit allows you to keep Roomba cleaning where you want it. Creating an invisible wall up to 13' long, the Virtual Wall Unit limits Roomba to one room, one section of a large space, or keeps it out of trouble spots without you lifting a finger. The Virtual Wall Unit requires two "D" alkaline batteries (not included). Additional Virtual Wall Units give you more control and more flexibility.

A beam of light tells Roomba where it shouldn.t go. Place a virtual wall wherever you want Roomba to keep out--Roomba reads it as a real wall and is confined to a designated area. Good for cleaning one room at a time.
