Cleaning Pattern
Roomba is a robot that cleans 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
criss-crosses 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 45 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 fastest cleaning and best performance, clear your floor of clutter and
use a Virtual Wall to confine Roomba to one room.
Brush
Caps
Cleaning Modes: While cleaning, Roomba automatically calculates the room
size and adjusts its cleaning time appropriately.
Spot Mode: Roomba will spiral approximately 3 feet in diameter and then
spiral back to where it started, intensely cleaning a localized area.

8iRobot Roomba 500 Series
Cleaning System
Roomba features a patented 3-stage cleaning system.
Floor Surfaces
Roomba works on wood, carpet, tile, vinyl and linoleum, and will automatically
adjust to different floor types.

and into corners.
2

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 3 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 cleaning time is programmed, Roomba enters scheduled cleaning
mode. When Roomba is scheduled to clean, it will occasionally flash its next
scheduled cleaning time to indicate it is scheduled. At the specified time,
Roobma leaves its Home Base, cleans, and then returns to the Home Base to
recharge when its done.
TIP: When using Roomba With Virtual Wall Lighthouses, Roomba will clean
for approximately 35 minutes per room.

10 iRobot Roomba 500 Series
Battery Storage and Charging
TIP: For best performance, always store Roomba’s battery in Roomba
with Roomba plugged in or on the Home Base. Charge Roomba’s battery
overnight for the first charge.
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.
Tip: If Roomba’s battery is warm, Roomba will wait for the battery to cool down
before beginning a charge cycle.
Tip: For long term storage, iRobot recommends that the battery be fully charged
and then removed from the robot and stored 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
When charging for the first time, or if Roomba has been left off the charger
for a long time, Roomba will initiate a special 16-hour charge cycle. This
extended charge refreshes Roomba’s battery and extends the life of
the battery. Roomba’s clean light will pulse quickly during the 16 hour
refresh charge.
Roomba is powered by a Nickel Metal Hydride (NiMH)
rechargeable battery. If maintained in good condition and in
accordance with the instruction manual, Roomba’s battery
lasts for hundreds of cleaning cycles.

Virtual Walls®(included with models 510 - 530)
The iRobot Roomba Virtual Walls create an invisible barrier that Roomba will
not cross. The Virtual Walls can be set to block an area ranging from zero to
eight feet long.
The Virtual Wall beam is keyhole shaped. A small halo prevents Roomba from
bumping into the Virtual Wall and a larger cone-shaped section blocks off
areas of your home where you don’t want Roomba to go.

Battery Installation
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.
Range Adjustment
Use the slider bar to adjust
the length of the barrier. A
higher range will drain the
battery faster.
TIP: Use the Virtual Walls to block doorways or to keep Roomba away from cords.
Confining Roomba to a single room will accelerate cleaning.
TIP: For best performance, place the Virtual Wall on the outside of the doorway
you wish to block. Set the Virtual Wall to the shortest setting possible to
extend battery life.
Additional Virtual Walls may be purchased by mail order from Domotec
Customer Service or domotec.uk.com
Virtual Walls are compatible with all 500 Series Roomba vacuuming robots.

Virtual Wall Lighthouses™ (models 535 and above)
Virtual Wall Lighthouses help Roomba navigate around your home, help
Roomba find the Home Base, and allow Roomba to clean one room before
starting the next. In Virtual Wall mode, they simply keep Roomba cleaning
where you want it and out of off-limit areas.

Virtual Wall Lighthouses™ (models 535 and above)
Lighthouse Mode
In Lighthouse mode, the Virtual Wall Lighthouse helps Roomba navigate
around your home and allows Roomba to clean room-to-room.
Place lighthouses in the doorway between two rooms. 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 lighthouses to navigate
back to the home base.
With two Virtual Wall
Lighthouses in lighthouse
mode, Roomba will clean
Room 1 for approximately
35 minutes, then clean
Rooms 2 and 3 for 35
minutes each, and then
return to the Home Base.

Home Base®
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 Power and Docked lights will be green to indicate Roomba is charging.
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.
