Step 2: Check for Blockages

  1. Detach the wand and cleaner head from the main body.
  2. Inspect the wand, hose, and cleaner head for any debris or blockages.
  3. Remove any visible obstructions carefully.

Step 3: Empty and Clean the Dustbin

Remove the dustbin and empty it thoroughly. Wash with warm water if necessary, and ensure it is completely dry before reattaching. A full or clogged dustbin can significantly reduce suction.

Step 4: Check and Clean Filters

  1. Remove the pre-filter and main filter according to your model’s instructions.
  2. Rinse the filters under cold water until clear, avoiding detergents.
  3. Allow filters to air dry completely before reinstalling (at least 24 hours).

Step 5: Verify Proper Assembly and Components

Ensure all parts, including the cleaner head, wand, and extension tube, are securely connected. Check for any damage or loose fittings that might disrupt airflow.
