Step 2: Inspect and Clean the Filters
- Remove the pre-filters and main filters from the vacuum according to the user manual.
- Rinse the filters with cold water until clean, avoiding soap or harsh cleaners.
- Allow the filters to air dry completely, ideally 24 hours, before reinstalling.
Clean filters regularly to prevent reduced suction caused by clogging or dirt buildup.
Step 3: Check for Blockages in the Wand and Cleaner Heads
- Detach the wand and cleaner heads from the vacuum body.
- Look for visible debris or hair obstructing the airflow pathways.
- Use a long, flexible brush or the crevice tool to clear any blockages.
Removing obstructions ensures unobstructed airflow for optimal suction.
Step 4: Verify Attachments and Seals
Ensure all attachments are securely connected and that seals are intact. A loose connection or broken seal can cause loss of suction. Refit any loose parts tightly.
Step 5: Test the Vacuum
Once you’ve cleaned filters, cleared blockages, and checked connections, power on your vacuum and test suction on a clean surface. If suction is restored, you’re done. If not, proceed to further troubleshooting or contact support.
