Storing Your Robot: For long-term storage, turn off the robot by removing it from the base and holding the power button for 10 seconds. Store the robot in a cool, dry place.

Note: It is highly recommended to use the Roomba® Home app to control cleaning. The mobile app can be used to clean specific rooms, set cleaning schedules, and create automations/schedules.

Cleaning Pattern: Your robot automatically explores and cleans your home in straight lines. It returns to the base at the end of a cleaning job or when it needs to recharge.

Tips:

Clear the floor of clutter before starting a cleaning cycle.
Use your robot daily to maintain your floors.

After 90 minutes of inactivity off the base, your robot will automatically end its cleaning job. If you are unsure whether your robot has finished or is paused, check the Roomba® Home app for its status.

AutoEmpty™: Your robot will automatically empty its dust bin at the end of each cleaning job.

Note: Roomba robots are generally designed to vacuum most floor types. iRobot does not recommend using the washing function on unfinished hardwood floors and certain laminate or vinyl floors due to potential water damage to the floor and/or subfloor. For more information, visit global.irobot.com.

Starting a Cleaning Routine from Your Base

If the clean water tank and dirty water tank are ready, proceed to Step 5. If the clean water tank or dirty water tank indicator lights are on:

Lift and remove the tank that requires attention.
Lift the tank latch to open it.
Empty the dirty water tank. Fill the clean water tank with water.
Close and lock the water tank covers. Replace the tanks in the base. Important: Ensure the latch is properly closed before reinstalling.
With the washing cloths attached, use the app or press the robot's button to send the robot back to the AutoWash™ base.

Washing and Drying of Cloths

Your robot will return to its base for cloth washing as needed during cleaning jobs, and once the cleaning is complete. Cloth drying will only occur at the end of its cleaning job.

Important: Do not interrupt the robot while the cloth washing is in progress. It is normal to hear noises throughout this process as the cloths spin and the wash bin fills and empties.

Once the operation is complete, the base will dry the washing cloths by blowing hot air on them. Drying may take several hours. You can choose different drying durations in the app. The base may emit a low hum when the drying system is active.

Consult the Roomba® Home app to manually start cloth washing, start or stop cloth drying, or customize washing settings.

Robot Maintenance and Care

To ensure optimal performance, regularly perform the following basic maintenance and care procedures. You can find additional demonstration videos in the Roomba® Home app. If you notice your robot picking up less debris from the floor, empty the bin, clean the filter, and clean the brushes.

Side Brush Cleaning

Pull the side brush to remove it. Remove hair, lint, or debris using the cleaning brush, then reinstall the side brush. Important: It is recommended to replace the side brush every 3 to 6 months for optimal cleaning.

Multi-Surface Brush Cleaning

Press the release tabs on the brush guard and lift to remove it.
Remove the multi-surface brush.
Remove hair from the multi-surface brush using the cleaning brush.
Reinstall the multi-surface brush and brush guard onto the robot. Note: For deep cleaning instructions for the multi-surface brush, visit global.irobot.com. Important: It is recommended to replace the multi-surface brush every 6 to 12 months for optimal cleaning.

Filter and Bin Cleaning

Lift the robot's top cover to remove it.
Press the bin release buttons to remove the dust bin.
Remove the filter.
Clean debris from the filter using the cleaning brush.
Open the bin door. Empty and clean debris from the dust bin and filter using the cleaning brush or a clean cloth. Close the bin door.
Reinsert the filter.
Replace the bin in the robot.
Replace the robot's top cover.

Bin Cleaning

Remove the bin, along with the filter, and open the bin door.
Rinse the dust bin with warm water. Important: The bin should not be put in the dishwasher.
Ensure the bin is completely dry. Reinsert the filter, then replace the bin in the robot. Important: For optimal robot and base performance, clean and/or replace robot filters as needed.

Front Wheel Cleaning

Use the cleaning brush to remove hair and debris from the front wheel. Important: If the front wheel is blocked by hair, lint, or debris, you risk damaging the floor. If the wheel does not spin freely after cleaning, contact customer service.

Cleaning of Charging Contacts, Sensors, and Camera Window

Remove the robot from its base and wipe the charging contacts and sensors with a clean, dry cloth or a slightly damp melamine foam. Important: Do not spray cleaning solution or water directly onto the sensors or their openings.

Base Filter Cleaning

Examine the base filter for any accumulation of lint and debris. Wipe with a clean, dry cloth to remove.

Base Maintenance and Care

To maintain optimal performance of your base, follow the procedures described on the following pages.

Cleaning the Washing Cloth System

Wipe the washing cloth bin with a clean, dry cloth. Check that nothing is blocking the drain port. You can use mild soap and a sponge for stubborn debris.

Bag Replacement

Pull the bin door towards you and upward to remove it.
Slide out the card. When pulled out, the bag automatically seals itself so dust and debris cannot escape.
To install a new bag, slide the card onto the guide rails.
Replace the bin door. Ensure it is properly aligned.

Water Tank Washing

Remove both water tanks.
Lift the water tank latch to open them.
Empty the dirty water tank.
Rinse both tanks with warm water. You can use mild soap and a sponge for stubborn debris. Important: Water tanks should not be put in the dishwasher.
Fill the clean water tank with water. Leave the dirty water tank empty.
Reinsert both water tanks. Important: Ensure the latch is properly closed on the water tanks before reinstalling them.

Troubleshooting

Robot Troubleshooting: Your robot will alert you to problems with a voice announcement or audible alert. The Roomba® Home app also provides notifications with steps to troubleshoot. If you are unsure whether the robot has finished or is paused, check the Roomba® Home app for its status.

Factory Reset: To restore factory settings, press and hold the power button for 5 seconds, then within 5 seconds, press and hold the return to base button for 5 seconds.

Battery Safety and Shipping Information:

Warning: Lithium-ion batteries and products containing them are subject to strict transportation regulations. If you need to ship your product for repair, travel, or any other reason, you MUST comply with the following shipping instructions.
The battery MUST be powered off before shipping.
Turn off the battery by removing the robot from the base and holding the power button for 10 seconds. Press the bumper for 10 seconds while holding the power button. All indicator lights will turn off.
Carefully pack the robot for shipping.

Base Troubleshooting: Your base will inform you of issues with indicator lights on the front of the tank and in the Roomba® Home app. If the base is not functioning as expected, refer to the errors in the Roomba® Home app.

Indicator Light	Common Error	Resolution
Solid Red	Bag full or missing	Replace the bag if it is full or missing. Ensure the bag is inserted correctly. If the problem persists, remove any debris from the opening at the bottom of the robot and base.

This product is equipped with a thermal protection system to prevent damage from overheating. The motor will stop running when the protection system activates. If this happens, unplug the appliance, let it cool for 30 minutes, remove any objects that may be obstructing the opening and evacuation tube, then plug it back in.
