Cleaning with Roomba Charging Roomba
For best battery performance, always
keep Roomba plugged in when not in use.
You need to charge Roomba
before cleaning for the first time.
1
Place APS battery into Roomba Robotic Floorvac.
Press down on both ends.
2
Plug the charger directly into Roomba.
3
Charge for 3 hours.
4
Power light will turn solid green to indicate a
full charge.
5
Unplug the charger and press clean.
Roomba will run for up to 120 minutes on hard
6
floors. Run times may vary based on floor surface.
Cleaning Pattern
Before cleaning with Roomba, clear the
floor of loose objects. If you don't
vacuum over it, don't use Roomba
over it (e.g., rug tassels, power and
blind cords).
Roomba will clean based on the
cleaning mode you select. Roomba has
three cleaning modes:
Clean mode - Roomba automatically
calculates the room size and adjusts its
cleaning time appropriately. Roomba
may clean for up to 60 minutes.
Max mode - Roomba will run until its
battery is nearly depleted, up to 120
minutes.
Spot mode - Roomba will spiral
approximately 3 feet in diameter and
then spiral back to where it started,
intensly cleaning a localized area.
You can use a Virtual Wall to block off
areas you don't want Roomba to enter.

Roomba Features
Sensor
Dirt Detect Mode
Roomba features the ability to clean more intensly in dirty areas. When Roomba finds a
particularly dirty area you will see the blue Dirt Detect light come on and Roomba will
change its cleaning pattern.
Roomba uses two sensors to recognize the dirtiest areas.To ensure optimal performance,
you may want to periodically wipe the sensors with a dry cloth. Roomba will sense heavy
debris like pepper, sand, and rice. Roomba will not sense pet hair or dust, but will pick
them up.

Roomba Accessories
Virtual Wall
Virtual Walls create a keyhole shaped area that Roomba will not
enter. Virtual Walls are great for keeping Roomba in or out of
rooms, or away from cords and other spots you don't want
Roomba to clean.
Virtual Walls will automatically shut off after approximately
130 minutes.
You can set Virtual Walls to block areas up to 13 feet wide.
Remember, at 13 feet, the far end of the beam will be very wide.
Frequently Asked Questions
What can I do if Roomba's battery does not seem to be charging?
If Roomba's battery is not charging, you should first make sure it is properly seated in Roomba.
When you insert the battery, you should hear two clicks. Then confirm that the green light on the
charging “brick” is a solid green and that the power indicator light is pulsing. If this does not work,
call customer service at 877-855-8593.
What should I do if Roomba repeatedly starts and stops, or just spins in place?
If Roomba is repeatedly starting and stopping, or just spinning in place, you may have a blocked cliff
sensor. Try cleaning the cliff sensors, located under the bumper, with a Q-tip or compressed air.
You also should remove and clean Roomba's brushes and brush bearings.
What can I do if Roomba is cleaning longer than I'd like in a particular room?
Roomba automatically calculates room size and run time based on a number of factors. Roomba
will clean for longer in rooms with more debris and furniture. Roomba also spends a little bit
longer cleaning rugs than hard floors. In an empty 8x10 room with hard floors, Roomba will clean
for approximately 20 minutes. Removing obstacles from a room will decrease the amount of time
Roomba needs to spend in a room.
