Streaks usually mean the pad is dirty, the tank is empty, or you're trying to mop over large debris.
Let's fix it step-by-step:
- Use a new pad. You should use a new, dry Braava jet m Series pad for each cleaning job. Do not pre-wet it. If you're using a washable pad, make sure it's thoroughly clean and completely dry before reusing.
- Check the tank. Make sure it's filled to the top with water. If you're using cleaning solution, add 6 capfuls of Braava jet Hard Floor Cleaning Solution to the empty tank first, then add water.
- Vacuum first. For optimal mopping, vacuum your floors to pick up large dirt and debris before running the Braava jet.
If that didn't work: Adjust the cleaning settings in the iRobot HOME App. You can modify the cleaning power, speed, and water spray amount for a deeper clean. Also, clean the spray nozzle on the bottom of the robot with a damp cloth to ensure it's not clogged.
Heads up: The robot is designed to clean each spot three times with some overlap. For a quicker clean, you can adjust the coverage in the app.
