Tips
- Before cleaning, remove any obstacles from the floor.
- Use the robot regularly to keep floors consistently clean.

AutoEmpty™
The robot will automatically empty its dustbin at the end of each cleaning routine.
NOTE: Roomba robots are generally designed for vacuuming most floor types. It is recommended not to use the washing functions on unsealed hardwood floors and some types of laminate/vinyl planks, as this could cause water damage to the floor and/or underneath it. For more information, visit global.irobot.com.
Starting a cleaning routine from the station
If the clean water tank and dirty water tanks are ready, proceed to step 5. If the clean or dirty water tank LEDs are lit:
Step 1: Remove tank
Lift to remove the tank requiring maintenance.
Step 2: Open tank
Lift the latch on the tank to open it.
Step 3: Empty and fill tanks
Empty the dirty water tank. Fill the clean water tank with water.
Cloth washing and drying
As needed, during cleaning routines and at the end of the operation, the robot will return to the station to wash the cloth. Cloth drying occurs only after washing is complete.
IMPORTANT: Do not interrupt the robot during cloth washing. It is normal to hear occasional noises during the entire process, as the cloths rotate and the washing basin fills and empties.
Once the operation is complete, the station proceeds with hot air drying of the cleaning cloths.
NOTE: The drying process may take several hours. You can use the app to choose different drying times. During this phase, you may hear a low humming sound from the base.
Access the Roomba Home App to manually start or stop cloth washing or drying, or to customize washing settings.
IMPORTANT: Ensure the latch is properly closed before reinstalling.
