Virtual Wall

Lighthouses
(optional accessory for selected models)
Virtual Wall Lighthouses turn on and off automatically as Roomba is
turned on and off. When they are on, a light illuminates on the top of the
Virtual Wall Lighthouse. A Virtual Wall Lighthouse can be used in two
modes, either in Lighthouse mode or Virtual Wall mode, set by the Mode
Selector.

Lighthouse Mode
In Lighthouse mode, the Virtual Wall Lighthouse helps Roomba navigate
around your home and allows Roomba to clean room-to-room. Roomba
will clean the room it starts in, navigate to the next room, and then clean
the second room. When Roomba has completed cleaning, it will use the
Lighthouse to navigate back to the Home Base for recharging.
With two Virtual Wall
Lighthouses in lighthouse
mode, Roomba will clean
Room 1 for approximately
25 minutes, then clean
Rooms 2 and 3 for 25
minutes each, and then
return to the Home Base.
