Symptoms
- Rattling or clicking sound while running
- High-pitched whine or whistle
- Grinding noise from the brush roll area
- Noise changes pitch when lifted off the floor
Likely causes
- CommonObject caught in the brush rollSmall hard objects like coins or LEGO pieces can rattle against the spinning brush.
- CommonAirflow blockage causing a whistleA partial clog forces air through a narrow gap, creating a high-pitched sound.
- PossibleWorn or slipping beltA stretched belt can squeal as it slips against the brush roll pulley.
- PossibleWorn brush roll bearingsBearings can grind as they wear out, especially near the end of the roll.
- Less commonFailing motor bearingsA grinding noise that persists with no brush roll contact may point to the motor itself.
What to do
- Turn off and unplug the vacuum right away if the noise sounds like grinding or rattling.
- Check the brush roll area for any hard objects lodged in it and remove them.
- Look for hair or debris tangled around the brush roll ends where bearings sit.
- Inspect the belt for wear, glazing, or slipping.
- Check the hose and filter for partial blockages that could cause whistling.
- Run the vacuum briefly off the floor (lifted, brush roll not engaged) to isolate whether the noise is from the brush or the motor.
- If the noise is clearly from the motor rather than the brush roll or belt, stop use and have it inspected professionally.
