Brush roll does not spin, but suction is present.

Safety first: Remove the battery and detach the floor head.

• Remove and clean brush roll: Unlock the end cap and pull out the roller. Cut away hair and debris from the roller and end caps.
• Check rotation: Spin the roller by hand. If stiff, replace the brush roll assembly.
• Inspect drive mechanism: Look inside the head for broken gears or debris around the motor spindle.
• Test with another head: If another motorized head works, replace the faulty head.
• If no powered heads work: The main body may not be supplying power to the head; main PCB or wand wiring may need service.
