If suction feels strong at the hose but weak on the floor, the blockage is likely inside the floorhead.
This commonly happens after vacuuming:
- Fabric items
- Paper products
- Hair ties
The floor nozzle contains narrow intake tunnels. Debris can lodge behind the brush roll and restrict airflow.
How to Diagnose
- Detach the wand and test suction directly.
- If suction is strong → the floorhead is restricted.
- Flip the vacuum over and inspect the brush area.
Use a flashlight to look inside the intake opening.
Clearing the Blockage
Use:
- A wooden stick
- Flexible plastic rod
- Long zip tie
Avoid sharp tools.
Also check:
- Side suction ports
- Elbow joints
- Brush roll chamber
If airflow issues continue, follow the complete system inspection guide.
