- Rinse the filters under cold water without soap.
- Gently squeeze out excess water and let them air dry completely (24 hours recommended).
- Reinstall once dry to restore suction.
Step 4: Empty and Check the Bin
Ensure the bin isn’t full. Remove it and empty any dust or debris. Confirm the bin is seated correctly, and the lid is closed tightly.
Step 5: Examine the Cleaner Head
