If cleaning filters and clearing blockages doesn’t restore suction, the motor or fan might be faulty. Consider contacting Dyson support or a qualified repair technician for further diagnosis.
Verify Power Mode and Battery
Ensure the vacuum is set to an appropriate power mode. The Power trigger helps conserve energy, so check if it’s fully engaged during cleaning.
Confirm the battery has sufficient charge and is functioning properly.
