iRobot Roomba Anatomy

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.

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 650 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

Floor Surfaces

1. Roomba works on wood, carpet, tile, vinyl, and linoleum, and adjusts automatically to different floor types.
2. 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
3. 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.

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.

Hour Refresh Charge

1. 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.
2. 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.

Charging Roomba

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®

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

1. 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
2. Virtual Wall blinks repeatedly twice to indicate that it needs new batteries. To save battery power, switch the Auto Virtual Wall to “Off”.
3. When in “Auto” mode, the batteries should last approximately six months.

Virtual Wall® Halo (optional accessory for all models)

1. The Virtual Wall Halo is perfect for homes with pets. It sets up a protective zone, gently guiding Roomba around your pet’s food and water bowls to keep the contents intact. To set up the Halo, take the Virtual Wall out of the sleeve.
2. Install batteries as shown on the previous page. Set the Virtual Wall to “Auto” mode and fully insert it into the sleeve.
3. Make sure the Virtual Wall is inserted all the way into the sleeve. The circular lens should be completely visible at the top.
4. Place the Virtual Wall Halo on the floor, level with Roomba, and in close proximity to the bowls as shown below. If you have one bowl, put it beside the Halo, almost touching the wall. For two bowls, place one on either side.

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 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

1. 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.
2. 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.
