Step 2: Check for Blockages
- Detach the cleaner head and extension wand from the main body.
- Inspect the wand, hose, and cleaner head for any debris or obstructions.
- Use a long, flexible object or the crevice tool to gently dislodge blockages.
Step 3: Clean or Replace Filters
Filters can clog over time, reducing suction. Remove the pre-filter and main filter as per your model’s instructions. Rinse filters under water, wring out excess moisture, and allow them to dry completely before reinstalling. If filters are damaged, replace them with compatible ones.
Step 4: Empty the Dust Bin
Ensure the dust bin isn’t full. Press the bin release button, empty the contents into the trash, and reattach securely. A full bin can significantly impair suction performance.
Step 5: Check Brush Bar and Attachments
Remove the brush bar from the cleaner head. Clear away hair, string, or debris tangled around it. Reassemble carefully and ensure it spins freely.
