Important Tips

Remove and clean Roombas brushes after every 3 uses. Roomba contains electronic parts. Do NOT submerge Roomba or spray with water. Clean with a dry cloth only. Always consult your floor manufacturer for approved cleaning methods.

For Best Performance

Roomba is very effective at picking up hair. Remove and clean Roombas brushes after every 3 uses. Empty Roombas bin and clean its filter after every 3 uses. Always store Roomba connected to its charger or Home Base. Use the Virtual Walls to keep Roomba cleaning where you want it. Keep wheels and brush free of hair and debris by inspecting and cleaning the bottom of the robot regularly.

Cleaning Pattern

Roomba is a robot that cleans differently than the way most people clean their floors. Roomba uses iRobots 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.

Filter

Side brush cleans 1
along edge of walls and into corners.

Two 2 counter-

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 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. Roombas battery can last for hundreds of cleaning cycles before a replacement is necessary.

Battery Life

To extend the battery life, we recommend storing Roombas battery in the robot with the power supply plugged in, or with Roomba on the Home Base. If stored correctly, Roombas battery will take less than 3 hours to recharge.

Cleaning Time

You should fully charge Roombas 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 Roombas battery and extends the life of the battery.
TIP: For best performance, always store Roombas battery in Roomba with Roomba plugged in or on the Home Base. Charge Roombas battery overnight for the first charge.

Charging Roomba

Charge Roomba in one of two ways:

Charging Lights

All Roomba models have a charging indicator light. Use this chart to determine the status of the battery:
Charging Indicator Light Red Amber pulse Solid green Battery Status Battery empty Charging Fully charged

4100 Model Series4200 Model Series
Charging Indicator Light Charging Indicator Light
TIP: When Roomba is on the Home Base, always make sure that the Home Base Power and Docked lights are on.

Virtual Walls

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 three to eight feet long.
TIP: Use the Virtual Walls to block doorways or to keep Roomba away from cords. Confining Roomba to a single room will accelerate cleaning.
T he Virtual Wall beam is keyhole shaped. A small halo prevents Roomba from bumping into the Virtual Wall and a larger lobe-shaped section blocks off areas of your home where you dont want Roomba to go.
Shape of Beam D Alkaline Batteries

Battery Installation

The Virtual Wall requires 2 D batteries and automatically shuts off after 110 minutes. If the power light blinks green, the batteries will soon need replacement.

(not included)

Battery Door

Range Adjustment

Use the slider bar to adjust the length of the barrier. A higher range will drain the battery faster.
TIP: or best performance, place the Virtual Wall on the outside of the F doorway you wish to block. Set the Virtual Wall to the shortest setting possible to extend battery life. TIP: Scheduling Virtual Walls (when programmed) will turn on a few minutes before Roomba. See page 18 for details.
Additional Virtual Walls may be purchased at www.irobot.com. 12 iRobot Roomba Owners Manual

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. To manually dock Roomba, place it within five feet of the Home Base and press Spot and Clean simultaneously. You can also drive Roomba toward the Home Base with the remote control, and Roomba will dock automatically.

Home Base Chair Table

Stairs

Area Rug

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

Remote Control

Spot Directional Buttons Power Clean Max Pause
The Roomba Remote Control lets you conveniently control Roombas functions. You can use it to turn Roomba on and off, and steer it around your room without bending down. It also gives you remote access to the following commands: Clean: Start Roomba in Clean mode. Spot: Start Roomba in Spot mode. Max: Start Roomba in Max mode. Pause: Pause Roomba in the middle of the cleaning cycle. Press pause again to continue. Before using your remote for the first time, you must install 2 AA batteries (sold separately).
TIP: You can use the remote to direct Roomba to the Home Base. Once Roomba is in range and can see the Home Base, it will return to the base and dock itself automatically.
T he Roomba Remote Control, Virtual Walls, and Home Base all 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 work when the robot is near Virtual Walls.

Scheduler Remote Control

From Discovery to Decision By Cathy Goodwin, Ph.D. From Discovery to Decision by Cathy Goodwin, Ph.D. "I just realized I have a talent for seeing patterns in random events and data. I can see how everything fits together while everyone around me remains confused." Hermione "My job drives me crazy. I spend hours preparing a presentation and, when the time comes, the client wants to talk about something entirely different." Marvin Hermione might enjoy many types of research or analysis anything from military intelligence to finance. She might be a planner anything from meetings to advertising strategy. Marvin might prefer a structured environment, where he's rewarded for carrying out approved plans rather than showing initiative and spontaneity. When clients say, "I've discovered a talent for." or, "I have a strong need for." I suggest they continue exploring options and opportunities. Talents and needs become part of the checklist you construct to assess potential opportunities. They rarely allow you to make a firm decision. And often they act as red flags signaling what not to do, rather than offering direct guidance. Hermione and Marvin need to see their new discoveries in the context of the rest of their lives. Does Hermione find herself drawn to chaotic environments where she can introduce order? Does she have a high tolerance for ambiguity? Does Marvin seek certainty when he moves to a new location or hires a career coach? Can he identify circumstances where he enjoys responding spontaneously? Some clients discover they cannot work around a particular need, such as a desire for structure or a craving for autonomy. Others can learn to operate in a new style. Marvin, for instance, may learn to trust his intuition and give up some need for structure.
Some clients learn that a certain talent must be the focus of their working lives. Others realize that expressing the same talent is a "nice to have." Hermione might find a dream job that doesn't seem to make use of her talent for seeing patterns in unrelated data. Or she may find ways to use this talent that aren't included in the job description. The first "aha" moment becomes, "Hold that thought." It's only by delving into the meaning of discovery that we can talk about its place in your business and career strategy.
