Your Roomba is powered by a rechargeable battery. Before using your Roomba 
for the first time, you’ll need to charge the battery overnight.
• Make sure your Roomba is fully charged before each cleaning cycle.
• 
For maximum battery life, always store your Roomba plugged in. 
• When your Roomba is on the Home Base, make sure the Home Base 
   power light is on. 
•     If you return your Roomba to the Home Base / battery charger after leaving  
it off for a long time, it will start a special Refresh Charge mode and the battery  
indicator will pulse quickly. If possible, don’t interrupt the Refresh Charge mode.
•  For long-term storage, fully charge the battery, remove, and store it in a  
cool, dry place.

How to use the Lighthouse mode
Simply place a Lighthouse in the doorway 
with the logo facing forward. When it has 
completed the first room the Lighthouse 
will help Roomba navigate around your 
home allowing it to clean room-to-room. 
When Roomba has completed cleaning, 
the Lighthouse will direct Roomba back 
to its Home Base for recharging.  
You can use Lighthouses and Virtual Walls 
at the same time, but avoid placing them 
too close to each other, to the Home Base, or to furniture that could block the invisible 
beams. Otherwise your Roomba might not recognize the Lighthouses or be able to  
return to Home Base. 
How to use the Virtual Wall mode
In Virtual Wall mode, the Lighthouse creates an invisible barrier that your Roomba won’t 
cross. It automatically turns off when your Roomba is turned off. 
Simply place the Virtual Wall Lighthouse in the center of the doorframe. Unlike a Virtual 
Wall, a Virtual Wall Lighthouse features a range selector that you can use to adjust the 
length of the barrier – up to 8 feet (2 meters) – (a longer range will drain the  
battery faster). 
How to remove your battery
If you won’t be using your Roomba for an extended period, we recommend that you
remove the battery. To access the battery, turn Roomba over and remove the two 
screws that hold Roomba’s battery cover in place.
