      Tiffany BoydJul 27, 2025
      If your Shark Vacuum Cleaner has restricted airflow, resulting in no or light suction, take these steps: First, check and clean the filters, ensuring you rinse and dry them completely before putting them back. Then, empty the dust cup if it's full. After that, inspect the hose, connections, nozzles, and accessories for any blockages and clear them. Finally, close the suction release on the handle to maximize suction power. If the dust cup is empty and attachments are clear, inspect for other blockages.

      If the brush roll on your Shark Vacuum Cleaner isn't spinning, immediately turn off and unplug the vacuum. Disconnect the nozzle and remove any blockage before reconnecting and turning the vacuum back on. Pull the handle toward you and release the floor nozzle to disengage the auto-off feature. Ensure the On/Off switch is in the “II - Brush Roll On” position.
