Roborock Q Revo S leaves my floors dirtier—how can I stop it?

First, make sure that the trash can and washable filter are clean and in the right place. Clogs or misalignment can greatly reduce airflow.

Regularly remove any hair or other waste from your main, side, and wheels brushes.

If you mop and then see streaks or residue, make sure the mop cloths are clean and attached correctly. 

Also, make sure the clean water tank is full and only uses Roborock-approved solution. Spots that are dirty are caused by mop pads that are dirty or not lined up right and low water levels.

If the floor is very dirty, change the app's wiping setting to "Deep" cleaning mode. This will use more water and stir the floor more, which will help remove more dirt.

Also, wipe down all of the sensors. Cliff, side, and wall sensors that are dusty or dirty can send the path in the wrong direction and leave some areas unexplored.

Finally, make sure the software is up-to-date and that the app's auto-empty dock and mop washing settings are turned on. This way, the robot can take care of itself while cleaning and not spread dirt around.

Do you have another way to solve it? We'd love to hear from you in the comments.
