Step 2: Check for Blockages
- Detach the wand and cleaner head from the main body.
- Inspect the wand, hose, and cleaner head for any visible debris or blockages.
- Clear any obstructions using a long, flexible brush or cloth.
Step 3: Clean or Replace Filters
Dirty filters can significantly reduce suction. Remove the pre-filter and filters from the vacuum. Rinse the filters with cold water, gently squeezing out excess water, and let them air dry completely (at least 24 hours) before reinstalling. Replace filters if they are worn or damaged.
Step 4: Examine the Brush Bar
Check the Digital Motorbar cleaner head for tangled hair or debris. Remove any obstructions carefully. If the brush bar is damaged or excessively worn, consider replacing it or the entire cleaner head.
Step 5: Verify Proper Assembly and Seal Integrity
Ensure all parts are securely attached and properly clicked into place. Check for broken seals or cracks in the wand, hose, or cleaner head, which can cause suction leaks.
