Inspect and Clear Blockages

Check the Power and Attachments
Confirm the vacuum is fully charged or plugged in. Inspect the power trigger and settings. Make sure attachments like the crevice tool are properly connected and not causing blockages.
Test the Vacuum
Power on the vacuum and test suction on a clean surface. If suction persists, repeat the above steps or consider replacing filters or parts if performance remains poor.
