Clean or Replace Filters
Dirty filters can restrict airflow, causing suction issues. Remove the pre-filters and main filters according to your model’s instructions. Rinse the filters under cold water, gently squeezing out dirt, then let them air dry completely (at least 24 hours) before reinstalling. Consider replacing filters if they look damaged or clogged beyond cleaning.
Inspect Battery and Power Settings
Ensure the battery is fully charged. If your vacuum’s LCD shows low power or the display indicates a problem, try charging for at least 3.5 hours. Also, verify you’re in the correct mode, and the power trigger is fully engaged during use. If the battery no longer holds charge, replacing it may be necessary.
Reassemble and Test
- Reattach all parts securely, ensuring they click into place.
- Turn on the vacuum and test suction on a small, clean area.
- If suction is restored, proceed with regular cleaning. If not, repeat previous steps or consider professional repair.
Additional Tips & Warnings
- Always disconnect from power before cleaning or inspecting internal parts.
- Do not use harsh chemicals or abrasive tools on filters or plastic parts.
- Regularly maintain your vacuum to prevent future issues.
