Cleaning Pattern
Roomba is a robot that cleans differently than the way most people clean
their floors. Roomba uses iRobot’s AWARE™ Robot Intelligence System to
determine the best way to pass over and clean every section of the floor.
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.
TIP: Wires should be elevated off of the floor and rug tassles should be tucked
under the rug to prevent Roomba from getting stuck.

Cleaning System
Roomba features a patented 3-stage cleaning system.
Floor Surfaces
Roomba works on wood, carpet, tile, vinyl, and linoleum, and will automatically
transition between different floor types. Roomba is not recommended for
shag carpet or rugs with tassels.

Cleaning Modes
Roomba will clean based on the cleaning mode you select. Roomba has up to
four cleaning modes, depending on your model:
Clean Mode (all models)
Roomba automatically calculates the room size and adjusts its cleaning time
appropriately. Roomba may clean for up to 60 minutes.
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.
Max Mode
Roomba runs until its battery is nearly depleted, up to 120 minutes.
Scheduled Cleaning Mode
When a cleaning time is programmed with the iRobot Scheduler Remote,
Roomba enters Scheduled Cleaning Mode. When Roomba is in Scheduled
Cleaning Mode, the status light blinks amber. At the specified time, Roomba
leaves its Home Base, cleans for up to 60 minutes and returns to the Home
Base to recharge when it is done.

Battery Storage and Charging
Roomba is powered by a Nickel Metal Hydride (NiMH)
rechargeable battery. Roomba’s battery can last for hundreds
of cleaning cycles before a replacement is necessary.
Battery Life
To extend the battery life, we recommend storing Roomba’s battery in the
robot with the power supply plugged in, or with Roomba on the Home Base. If
stored correctly, Roomba’s battery will take less than 3 hours to recharge.
Cleaning Time
You should fully charge Roomba’s battery before each cleaning cycle. When
fully charged, Roomba will clean for up to 120 minutes on hard floors and for
slightly less time on rugs.
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.
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.
Charging Roomba
Charge Roomba in one of two ways:
