Step 2: Empty the Dust Bin

  1. Remove the dust bin from the vacuum body.
  2. Press the bin release button and empty it into a trash bag.
  3. Check for any blockages or debris stuck in the dust chamber.

A full or clogged dust bin can restrict airflow, reducing suction.

Step 3: Check and Clean the Filters

Remove the pre-filters and main filters from your vacuum. Rinse them under cold water until clear, then let them air dry completely—this may take up to 24 hours. Once dry, reinstall the filters. Dirty or clogged filters severely impact suction.

Step 4: Inspect for Blockages

  1. Detach the cleaner head and wand from the main body.
  2. Look for obstructions in the wand, cleaner head, and hose. Remove any hair, debris, or blockages.
  3. Use the crevice tool (recommended: LANMU Crevice Tool) to reach tight spots.

Blocked passages prevent airflow and cause suction loss.

Step 5: Examine the Brush Bar and Attachments

Remove hair and debris tangled around the Digital Motorbar cleaner head or brush bar. Use scissors if needed, and ensure the brush spins freely. Reassemble carefully.
