Why is my Bissell 3748 Vacuum Cleaner losing suction power?
- JJeffrey PerryAug 10, 2025
Loss of suction power in your Bissell Vacuum Cleaner may occur if the tanks are not seated properly. Ensure both tanks are correctly reseated. Another cause might be a full dirty water tank; empty it. Also, check the rubber tab on the dirty water tank and press firmly to seal it tightly. Make sure the accessory hose door is closed and locked, and that the nozzle is correctly installed; try removing and reinstalling it.
