Step 2: Check and Clean the Pre-Filters
- Remove the pre-filters located near the cyclone assembly.
- Rinse the filters under cold water until clean.
- Allow them to air dry completely before reinstalling.
Clean filters maintain proper airflow and suction. Replacing or neglecting filters can cause significant performance issues.
Step 3: Inspect for Blockages
- Check the wand, cleaner head, and hose for debris or obstructions.
- Remove any visible blockages carefully.
- Use the crevice tool (recommended: LANMU Crevice Tool) to reach tight spots.
Blocked airflow is a common cause of suction loss. Clearing obstructions restores suction power.
Step 4: Examine the Cyclone and Bin
- Remove the cyclone assembly and empty the dust bin.
- Check for accumulated debris or clogs in the cyclone.
- Clean the cyclone with a damp cloth if necessary.
A full or clogged cyclone reduces airflow, affecting suction. Keep these areas clean for optimal performance.
Step 5: Verify Attachments and Seal Integrity
- Ensure all attachments are securely connected.
- Inspect for cracks or worn seals on the wand and cleaner head.
Loose fittings or damaged seals can cause air leaks and suction loss. Replace parts if needed.
