Step 1: Power Off and Unplug

Before inspecting or cleaning your vacuum, turn it off and unplug it from the charging station or power outlet. This ensures safety during maintenance and prevents accidental activation.

Step 2: Check the Dustbin and Empty

  1. Remove the dustbin from the vacuum body.
  2. Empty all debris into a trash bin.
  3. Reinstall the dustbin securely.

A full dustbin can significantly reduce suction, so make this a regular part of your maintenance routine.

Step 3: Inspect and Clean the Filters

Locate the pre-filter and main filter as per your model’s manual. Remove the filters and rinse them under cold water. Allow them to air dry completely before reinstalling. Consider replacing filters if they appear damaged or excessively dirty.

Step 4: Check for Blockages

  • Detach the cleaner head and wand components.
  • Inspect hoses and tubes for debris or hair clogs.
  • Use a long, flexible brush or a straightened coat hanger to clear any blockages.

Clear airflow pathways are crucial for suction power. Make sure all parts are free from obstructions.

Step 5: Examine and Clean the Brush Bar

Remove the brush bar from the cleaner head. Remove tangled hair, fibers, and debris carefully. Reassemble the head and ensure the brush spins freely. A clean brush bar enhances dirt pickup and airflow.
