Brushes do not spin, but there is suction and spray

Safety: Unplug the unit and lay it on its back for access.

• Remove debris: Cut away hair, threads, and fibers wrapped around the brush roll and end caps.
• Inspect belt: Remove the belt cover and check the belt condition. Replace if cracked, stretched, or broken.
• Check brush bearings: Spin the brush roll by hand. If it feels rough or seized, replace the brush roll assembly.
• Verify clutch engagement: If your Siemens model has a brush on/off selector, ensure it is set to ON and the linkage is intact.

After replacing the belt or brush roll, reassemble and test on a small area of carpet.
