Vacuum suddenly became much louder than usual

Symptoms

• Vacuum noise level jumped noticeably from one use to the next
• New rattling or whirring sound not present before
• Loudness paired with reduced suction or performance
• Noise started right after a specific event, like hitting an object

Likely causes

• CommonNew clog restricting airflow, increasing motor strain soundA sudden blockage can make the motor sound noticeably louder and more strained.
• CommonObject recently vacuumed up rattling insideA small hard object pulled in recently, like a coin or bead, can rattle loudly against the brush roll or fan.
• PossibleLoose panel or cover not fully latchedA cover that didn't snap fully shut after the last cleaning can vibrate and add noise.
• PossibleBelt slipping after recent brush roll jamA recent jam can leave the belt stretched or slipping, adding a new noise.
• Less commonDamaged fan blade from an ingested hard objectA hard object reaching the fan can chip or bend a blade, causing ongoing noise and vibration.

What to do

1. Turn off and unplug the vacuum right away since sudden loud noise often means something is wrong.
2. Check all panels, lids, and the bin to make sure everything is fully latched shut.
3. Look and listen for a rattling object by gently shaking the vacuum body (while off and unplugged).
4. Remove the bin, filter, and brush roll to check for a recently ingested hard object.
5. Check the belt condition if the noise coincided with a recent jam or tangle.
6. If you find and remove a rattling object, test the vacuum again to confirm the noise is gone.
7. If noise continues with no found object or clog, especially with reduced suction, have a technician check for fan blade damage.

When to call a pro

If noise persists with no found cause and suction is also reduced, a technician should check for fan blade damage from an ingested object.
