Step 2: Check for Blockages

  1. Detach the cleaner head and wand from the main body.
  2. Inspect the hose, wand, and cleaner head for obstructions or debris.
  3. Use a long, flexible tool or your fingers to clear any blockages.

Ensure the dustbin is empty and free of debris. Wash it with water if needed, and dry thoroughly to prevent mold or damage. Proper airflow depends on a clean dustbin.

Step 5: Check the Brush Bar and Attachments

  1. Remove the brush bar and clear away tangled hair or debris.
  2. Inspect the drive belt for wear or damage.
