6 iRobot Roomba 500 Series
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.
Dirt Detection: When
Roomba senses dirt, the
blue Dirt Detect™ light is lit
and Roomba cleans more
intensely in that 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 7
Cleaning Modes
Roomba will clean based on the cleaning mode you select. Roomba has
three cleaning modes.
Clean Mode (all models)
Roomba automatically calculates the room size and adjusts its cleaning
time appropriately.
Spot Mode (all models)
Roomba will spiral approximately three feet in diameter and then spiral
back to where it started, intensely cleaning a localized area.
Scheduled Cleaning Mode (Models 550 and above)
When a future cleaning time is programmed, Roomba enters Scheduled
Cleaning Mode. When scheduled to clean, Roomba will occasionally flash
its next cleaning time to remind you of its schedule. At the specified time,
Roomba leaves its Home Base, cleans, and then returns to the Home
Base to recharge when it’s done.

Cleaning System
Roomba features a patented three-stage cleaning system.

edge of walls and
into corners.
Two counter-
2
rotating brushes
scoop up dirt,
hair, and debris
into the bin.
Powerful vacuum picks up the
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 might
stall when confronting rounded edges and might slide over particularly
slippery surfaces. Extremely dark-colored floors may contribute to
Roomba’s cliff sensors working less effectively.
Anti-Tangle system
Roomba won’t get stuck on cords, carpet fringe or tassels. When Roomba
senses it has picked up a cord or tassel, it will automatically stop its main
brushes or side brush and try to escape. Roomba may make a clicking
noise when anti-tangle is activated.
For more detailed information, visit: www.irobot.com 9
Cleaning Bins
Roomba is compatible with two interchangeable cleaning bins.
Vacuum Cleaning Bin
The vacuum cleaning bin should be used for everyday cleaning. The dual
action, counter-rotating brushes pick up debris, while the vacuum sucks
up the dirt and dust.
High-Capacity Sweeper Bin (optional accessory for all models)
The high-capacity sweeper bin can hold more debris than the vacuum
cleaning bin. Use this bin when cleaning larger-than-usual amounts of dirt
and dust, or when cleaning bigger pieces of debris.

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 power supply, 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 power supply or Home Base 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 11
Charging Roomba
Charge Roomba in one of two ways:
Or
Using the Home Base Using the Power Supply Only
TIP: When Roomba is on the Home Base, always make sure that the Home
Base power light is on.
Charging Lights
Roomba uses the CLEAN button light to indicate that it is charging. Use
this chart to determine the status of the battery.

Virtual Wall
®
(optional accessory for all 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: Point the arrows on top of the Virtual Wall towards the opening you would
like to block.
TIP: For best performance, place the Virtual Wall on the outside of the
doorway you wish to block.
Manual Virtual Wall
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.
Auto Virtual Wall
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.

In Lighthouse mode, the Virtual Wall Lighthouse helps Roomba navigate
around your home and allows Roomba to clean room-to-room. Roomba
will clean the room it starts in, navigate to the next room, and then clean
the second room. When Roomba has completed cleaning, it will use the
Lighthouse to navigate back to the Home Base for recharging.

Virtual Wall Mode
In Virtual Wall mode, the Lighthouse creates an invisible barrier that
Roomba will not cross. It automatically turns off when Roomba turns off.
In Virtual Wall mode, place the Virtual Wall Lighthouse in the center of
the door frame. It blocks an opening up to seven feet or longer in three
increments: 0-3 ft., 4-7 ft., 7+ ft. Use the range selector to adjust the
length of the barrier. A longer range will drain the battery faster.
Range
Selector
TIP: Avoid placing Virtual Wall Lighthouses too close to each other, the
Home Base, or furniture that could block the beams. Doing so could
prevent Roomba from recognizing the Lighthouses and navigating to the
next room.
TIP: To conserve battery life, remove the batteries if you are not planning to
use the Virtual Wall Lighthouse when cleaning. When battery levels are
low, the Virtual Wall Lighthouse power light will ash repeatedly.

Home Base
(optional accessory for models 520 and above)
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 the Home Base is plugged
in, the power light will blink to indicate that the Home Base is connected
to the power source. When Roomba connects to the Home Base, the
power light will be solid to indicate that Roomba has successfully
connected to the Home Base. When Roomba is charging, Roomba’s
“Clean” button will pulse amber as described in the “Battery Storage and
Charging” section of this manual. The “Clean” button will be a solid green
when Roomba is completely charged.
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 at the end of a cleaning
cycle. Locate the Home Base against a wall or other immovable object to
prevent it from sliding during docking. If Roomba is unable to dock on its
first attempt, it will try again until it docks successfully.

Why does Roomba’s Side Brush occasionally spin backwards?
When caught on items such as carpet tassels or wires, the Side Brush
may spin slowly or briefly spin backwards to free itself. This may also
occur on thick or high-pile carpets. If this behavior should occur on hard
floor surfaces or when no tassels or wires are present, the Side Brush
should be cleaned. Using a small Philips head screwdriver, rst remove
the screw from the center of the Side Brush. Next remove the Side Brush
and thoroughly clean any hair or debris that is wrapped around the shaft.
Then reinstall the Side Brush and Side Brush screw.
Why does Roomba occasionally make a thumping sound?
When Roomba’s brushes encounter items such as carpet tassels or wires,
the brushes will briefly reverse direction to get free. This action causes
a thumping sound that can be heard approximately once per second
until the brushes are free from obstruction. If Roomba makes a thumping
sound when no tassels or wires are present, the main brushes should be
cleaned as described on page 22.
Why doesn’t Roomba slow down as it approaches certain
obstacles?
Roomba uses its Light Touch Bumper technology to identify walls and
other obstacles, allowing it to slow down and gently touch the obstacle
with its bumper before changing direction. Roomba may be less effective
at sensing and slowing down for extremely dark or black surfaces, or for
objects that are less than two inches wide.
