Symptoms
- Suction feels weak or absent through the vacuum tube
- Leaves get partially pulled in then stop
- Bag doesn't fill even after extended use
- Rattling or grinding noise from the impeller housing
Likely causes
- CommonClogged impeller or shredder bladesSticks, wet leaves, or debris can jam the shredding mechanism and stop airflow.
- CommonTorn or unzipped collection bagA hole or open zipper lets suction escape instead of pulling debris in.
- PossibleVacuum tube not fully seatedA loose connection between tube sections breaks the air seal needed for suction.
- PossibleDebris too wet or denseWet, matted leaves resist being pulled through the tube even with good suction.
- Less commonWorn or cracked impeller fan bladesDamaged blades move less air even when spinning at full speed.
What to do
- Turn off and unplug or remove the battery before inspecting the impeller area.
- Remove the vacuum tube and check the impeller housing for jammed sticks or debris, clearing anything visible.
- Inspect the collection bag for tears or an unzipped bottom seam and repair or replace if needed.
- Reattach the vacuum tube sections firmly, confirming there's no gap where air could leak in.
- Avoid vacuuming very wet leaves, which resist suction regardless of the machine's condition.
- Check the impeller fan blades for cracks or chips if suction still seems weak after clearing debris.
- If suction remains poor after all checks, the motor or impeller assembly may need professional service.
