Cleaning Pattern
Roomba is a robot that cleans floors differently than the way most people
clean their floors. Roomba uses its robot intelligence to efficiently clean
the whole floor, under and around furniture, and along walls.
Roomba calculates the optimal cleaning path as it cleans and determines
when to use its various cleaning behaviors.
Spiraling: Roomba uses
a spiral motion to clean a
concentrated area.
Wall Following: Roomba uses
this technique to clean the
full perimeter of the room and
navigate around furniture and
obstacles.
Room Crossing: Roomba
crisscrosses the room to
ensure full cleaning coverage.
Cleaning Modes
Roomba will clean based on the cleaning mode you select. Roomba has
two cleaning modes:
Clean Mode
Roomba automatically calculates the room size and adjusts its cleaning
time appropriately.
Spot Mode
Roomba will spiral approximately three feet in diameter and then spiral
back to where it started, intensely cleaning a localized area.
TIP: Roomba takes approximately 25 minutes to clean an average room and
will pass over the same area of the floor multiple times to ensure total
floor coverage.
TIP: For most efcient cleaning, clear your oor of clutter and use a Virtual
Wall to confine Roomba to one room.
For more detailed information, visit: www.irobot.com 11
Cleaning System
Roomba features a patented three-stage cleaning system.

3
remaining fine particles, dirt, and
hair. The filter traps dust and
small particles.
Floor Surfaces
Roomba works on wood, carpet, tile, vinyl, and linoleum, and adjusts
automatically to different floor types.
Roomba automatically senses stairs and other cliffs. Roomba is not
recommended for shag carpet or rugs with tassels.
12 iRobot Roomba Owner’s Manual
Battery Storage and Charging
Roomba is powered by a rechargeable battery.
Roomba’s battery can last for hundreds of
cleaning cycles if cared for properly.
Battery Life
To extend the battery life, iRobot recommends always storing Roomba
plugged in. For more details on how to maintain Roomba’s battery life,
visit www.irobot.com/support.
TIP: Recharge Roomba as soon as possible. Waiting several days to recharge
Roomba can damage the battery.
TIP: For storage off the charger, remove the battery from Roomba and store in
a cool, dry place.
Cleaning Time
You should fully charge Roomba’s battery before each cleaning cycle.
When fully charged, Roomba’s battery will last for at least one full clean
cycle.
16-Hour Refresh Charge
If Roomba has been left off the charger for an extended period, Roomba
will initiate a special 16-hour charge cycle. This extensive charge
refreshes Roomba’s battery and extends the battery life. While charging,
Roomba’s “Clean” button will pulse quickly. Note: For best results, do not
interrupt this Refresh Charge.
TIP: For best performance, charge Roomba’s battery overnight before using
Roomba for the first time.
For more detailed information, visit: www.irobot.com 13
Charging Roomba
Charge Roomba by plugging the charger directly into Roomba’s battery
charger socket.
Or
Charging Lights
Roomba uses the CLEAN button light to indicate that it is charging.

Virtual Wall
®
(optional accessory for select models)
Virtual Walls create an invisible barrier
that Roomba will not cross. This invisible
barrier can be used to confine Roomba
to a particular room or area, and
prevent it from getting too close
to electrical or computer cords,
delicate objects on the floor, etc.
The Virtual Walls can be set to block
an opening up to seven feet long.
Note that the width of the Virtual Wall’s
beam also increases as its length increases,
creating a cone-shaped area which Roomba cannot pass. The Virtual Wall
also creates a halo of protection around itself, preventing Roomba from
getting too close.
TIP: For best performance, place the Virtual Wall on the outside of the
doorway you wish to block.
Slim Virtual Wall (models 400-420)
The Virtual Wall requires 2 “D” batteries and
automatically shuts off after 135 minutes.
If the power light blinks green, the batteries
will soon need replacement. Use the slider
bar to adjust the length of the barrier.
A higher range will drain the battery faster.
TIP: Point the iRobot logo towards the opening you would like to block.
TIP: Scheduling Virtual Walls (when programmed) will turn on a few minutes
before Roomba.
For more detailed information, visit: www.irobot.com 15
Virtual Wall

Compact Manual Virtual Wall
(models 430 and up)
A Manual Virtual Wall must be turned on
by hand at the beginning of the cleaning
cycle to activate the barrier. A Manual
Virtual Wall and its power light will shut
off after 135 minutes. When battery levels
are low, the Virtual Wall power light will
blink slowly to indicate that it needs new batteries.
TIP: Point the arrows on top of the Virtual Wall towards the opening you would
like to block.
Compact Auto Virtual Wall
(models 430 and up)
When an Auto Virtual Wall is set to “Auto”
mode, the power light blinks repeatedly
to indicate it is on. When battery levels
are low, the Virtual Wall blinks repeatedly
twice to indicate that it needs new batteries.
To save battery power, switch the Auto
Virtual Wall to “Off.” When in “Auto” mode, the
batteries should last approximately six months.
TIP: Point the arrows on top of the Virtual Wall towards the opening you would
like to block.
Compact Virtual Wall Battery Installation
To open the battery compartment, simply apply pressure on both iRobot
logos located on either side of the Virtual Wall and pull the bottom out,
separating the pieces.

Home Base
®
(select models)
Roomba returns 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. When Roomba is on the Home
Base, the lights on the Home Base will be solid to indicate Roomba is
connected to the Home Base.
Home Base Location
You should position the Home Base on a hard level surface and in an
area where Roomba has a clear path to return to the dock at the end of a
cleaning cycle. If Roomba is unable to dock on its first attempt, it will try
again until it successfully docks.
CHAIR

The Roomba Remote, Virtual Wall and Home Base operate using an invisible
infrared beam. If they are all used in the same area, Roomba may see
multiple infrared signals and will not operate. The Remote WILL NOT dock
if you have a Virtual Wall near the Home Base. Fluorescent lights can also
impact Virtual Wall and Home base performance.

Remote Control
