Step 3: Inspect and Clean the Filters

  • Remove the pre-filter and/or post-filter as per your model’s instructions.

  • Allow filters to air dry completely (at least 24 hours) before reinstalling.

Step 4: Check for Blockages

  1. Detach the cleaner head and wand, inspecting for visible debris or obstructions.
