Possible Causes
How to Fix / Troubleshooting
Safety first: Remove the battery pack before inspecting moving parts.
Isolate the source:
- Run the vacuum briefly without the floorhead (using only the main body) to see if the noise comes from the motor or the floorhead.
If noise is in the floorhead:
- Remove the brushroll and clean hair and debris from the end caps and bearings.
- If the brushroll still feels rough or noisy when spun by hand, replace the brushroll assembly.
If noise is in the main body:
- The main motor bearings or fan are likely worn or damaged. Continued use can lead to complete motor failure.
In this case, replace the main suction motor assembly. This repair involves disassembling the body and is best performed by a qualified technician.
