That rattling is almost always something wrapped around the brush roll. It's a common issue. Here's how to fix it.
- Unplug the vacuum. Safety first.
- Turn the vacuum over so you can see the brush roll underneath the cleaner head.
- Look for any string, hair, or debris tangled around the ends of the brush roll or along its length.
- Use scissors to carefully cut and remove any wrapped material. Don't pull hard on the brush roll itself.
- Once clear, manually spin the brush roll with your hand. It should turn freely and quietly.
IF THAT DIDN'T WORK: If the brush roll spins freely but the noise persists when you turn it on, the issue could be a worn or damaged brush roll belt, or a foreign object inside the cleaner head housing. You'll need to check the belt and clear any debris from inside the housing.
HEADS UP: Regularly checking and cleaning the brush roll prevents this noise and keeps suction strong. Make it part of your routine after vacuuming high-pile rugs or areas with long hair.
