A Virtual Wall Lighthouse can act as both a Lighthouse and a Virtual Wall.
In Lighthouse mode, it allows Roomba to efficiently clean multiple rooms
before returning to the Home Base.
In Virtual Wall mode, it blocks off areas you don’t want cleaned.
Simply use the Mode Selector to make your choice. Either way, the Lighthouse turns
on and off automatically as you turn Roomba on and off. When on, the light on top is lit.
Each Lighthouse runs on two C alkaline batteries. A flashing power light means the
batteries need replacing soon.
How to use the Lighthouse mode
Simply place a Lighthouse in the doorway with the logo facing forward. When Roomba
has completed the first room, the Lighthouse will help it navigate around your home,
allowing it to clean room-to-room. When Roomba has completed cleaning, the
Lighthouse will direct it back to its Home Base for recharging.
You can use Lighthouse devices and Virtual Wall barriers at the same time. However,
please avoid placing them too close to each other, to the Home Base or to furniture
that could block the invisible beams. Otherwise, Roomba might not recognize the
Lighthouses or be able to return to its Home Base.
How to use the Virtual Wall mode
In Virtual Wall mode, the Lighthouse creates an invisible barrier that Roomba won’t
cross. It automatically turns off when Roomba is turned off.
Simply place the Lighthouse in the center of the doorframe. Unlike a Virtual Wall, a
Lighthouse features a range selector that lets you adjust the length of the barrier — up to
eight feet (2.4 meters). Please note: setting a longer range will drain the battery faster.
