Virtual Wall Lighthouses
Virtual Wall Mode
In Virtual Wall mode, the Lighthouse creates an invisible barrier that
Roomba will not cross.
Use the slider bar to adjust the length of the barrier. A higher range will drain
the battery faster.
In Virtual Wall mode, the Lighthouse blocks an area ranging from zero to
eight feet (2.4m) long. A small halo prevents Roomba from bumping into the
Lighthouse and a larger cone-shaped area blocks off areas of your home where
you don't want Roomba to go.
TIP: Use Virtual Wall Lighthouses in Virtual Wall mode to block doorways or to
keep Roomba out of off-limit areas.
TIP: In Virtual Wall mode, iRobot recommends setting up the Virtual Wall
Lighthouse behind the door jam as shown on pg. 12.
