Cleaning with Roomba Charging Roomba
For best battery performance,
always keep Roomba plugged in or on
the Home Base 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 or
place Roomba on the Home Base while
the Base is plugged in.
3
Charge for 3 hours.

full charge.
5
Unplug the charger and press clean or just
press clean if Roomba is on the Home Base.
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 four
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 and will
then return to the Home Base.
Spot mode - Roomba will spiral approximately 3 feet in diameter and then spiral back to
where it started, intensly cleaning a localized area.
Scheduled Cleaning Mode - When iRobot Roomba receives a cleaning time from Scheduler,
Roomba enters Scheduled Cleaning Mode. When Roomba is in Scheduled Cleaning Mode, the
Status light will blink amber. Roomba will leave it’s Home Base at the specified time, clean for
up to 60 minutes, and return to the Home Base to recharge at the end of the cleaning cycle.

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.

Sending Schedules Sending Schedules
After setting a cleaning time, you need to send the schedule to iRobot Roomba.
To send a schedule to your Roomba:
Using iRobot Scheduler
To send a schedule to your Virtual Walls:
Power on Roomba. Make sure all Vir tual Walls are off when using iRobot Scheduler,
and that Roomba is 8 feet away from the Home Base
OR that Roomba is completely
on the Home Base and both LEDs are on.
Open Scheduler's cover, point Scheduler at Roomba and press
Send All.The image will flash to indicate Scheduler is sending
code. Roomba will play a song to indicate the schedule is
received and the Status light will begin blinking.
Make sure Roomba is on the Home Base or in the center of
the area you want to clean. Roomba will clean at the time you
have scheduled.
Roomba's Status light will blink amber to indicate that
Roomba is scheduled to clean.
iRobot Scheduler,Virtual Walls, and Home Base all operate using invisible infra red beams. If used in the same
area, Roomba may see multiple infra red signals and not respond to commands.

Press and hold the power button on the Virtual Wall
Scheduler until the Scheduled light turns on.
Power Button
Point Scheduler at each Virtual Wall and press Send All to send
the schedule.The image will flash to indicate the Scheduler is
sending the schedule.
The Virtual Wall's Scheduled light will blink indicating that the wall is scheduled to
automatically turn on at the time you programmed.
You can clear the schedule from the Virtual Wall Schedulers by removing the batteries from
the Virtual Walls, or by deleting all cleaning times from the remote and re-sending the clear
schedule to the Virtual Wall Schedulers.

Roomba Accessories
Virtual Wall
Virtual Walls create a keyhole–shaped area that iRobot Roomba will not enter.Virtual Walls
are great for keeping Roomba in one room, or away from cords and other spots you don't
want Roomba to clean.
You can program Virtual Wall Schedulers to turn on at the same time as Roomba.
See page 13 for details.
Virtual Walls will automatically shut off after approximately 100 minutes in scheduled mode and
130 minutes in standard mode.
You can set Virtual Walls to cover areas up to 13 feet wide.
Virtual Walls create an infrared signal similar to
that of the Home Base and iRobot Roomba
Remote.
DO NOT set up Virtual Walls near the
Home Base or iRobot Roomba will be confused
by multiple IR signals and not dock.

Send Roomba to the Home Base by directin Roomba in the
front of the Home Base with the remote. Roomba will see the
Home Base and return automatically.You can also tell Roomba
to look for the Home Base by pressing Spot and Clean simultaneously.

Home Base
Roomba will return to the Home Base at the end of a cleaning cycle or when its battery
is running low. Roomba needs to find the infrared signal of the Home Base in order to
return.
Always keep the Home Base plugged in.
Be sure to keep your Home Base on a hard level surface and in an area where Roomba
has a clear path to the dock so Roomba can return at the end of a cleaning cycle.
To manually dock Roomba, place it within 5 feet of the Home Base and press Spot and
Clean simultaneously, or just drive Roomba near the Home Base with the remote,
Roomba will dock automatically.
The Roomba Remote,Virtual Wall, and Home Base all operate using an invisible infra red technology. If they are all
used in the same area, Roomba may see multiple infra red signals and not operate. Roomba WILL NOT dock if you
have a Virtual Wall near the Home Base.

Frequently Asked Questions
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 Roomba is not
charging on the Home Base, try charging Roomba by plugging the charger directly into the robot..
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.
What can I do to help Roomba get back to the Home Base?
The Home Base creates an infrared "beam" that Roomba needs to find in order to return successfully. You should make sure that the Home Base is plugged in, the power light is on, and the base is
on a flat, level surface. Do not use any Virtual Walls near the Home Base, the Virtual Walls use an
infrared signal similar to that of the Home Base that may prevent Roomba from successfuly docking. If you have a particularly large home, Roomba may have trouble finding the Home Base at the
end of a cleaning cycle. If it does, tr y repositioning the Home Base.
What should I do if Roomba does not respond to Scheduler commands?
When sending schedules to Roomba, make sure that Roomba is 8 feet away from the Home Base
OR that Roomba is completely on the Home Base and that both Home Base lights are on. Also,
make sure that any Virtual Walls in the area are turned off. Finally, when using Scheduler, point it at
Roomba and make sure that the black window on the top of Scheduler is not blocked by the
cover or any other obstacles.
How do I adjust LCD contrast?
When Scheduler’s cover is open, press Delete and Send All simultaneously.The screen will read
"LCD 21".To adjust the LCD contrast, press or . Press
How do I turn Scheduler off?
Scheduler does not need to be turned off.The power button on Scheduler is for turning the robot
on and off.
My robot stopped blinking its status light and lost its schedule, is something wrong?
Occasionally, Roomba may receive a static charge from carpets or hard floors, which can, in rare
cases, cause Roomba to lose its schedule. Re-send the schedule to Roomba to resolve the problem
(see page 12).
