Step 2: Check for Blockages
- Detach the wand and cleaner head from the main body.
- Inspect the wand, hose, and cleaner head for visible debris or obstructions.
- Remove any blockages carefully, ensuring no debris remains that could impede airflow.
Step 3: Clean or Replace Filters
Dirty filters can significantly reduce suction. Remove the pre-filters and main filters according to your model’s instructions. Rinse the filters under cold water until clear, then let them air dry completely for at least 24 hours before reinstalling. Consider replacing filters if they are damaged or overly dirty.
Step 4: Empty the Dust Bin
Full dust bins restrict airflow. Press the bin release button and empty the contents into your trash. Ensure the bin is securely reattached before testing again.
Step 5: Check the Brush Bar
Inspect the Digital Motorbar cleaner head for tangled hair, threads, or debris. Clear any obstructions carefully to ensure the brush rotates freely, promoting effective cleaning and airflow.
