Vacuum emits a burning smell from the brush head during use.

Safety first: Immediately turn off the vacuum, remove the battery, and let the head cool. Do not continue using it until inspected.

• Remove brush: Open the floor head and take out the main brush. Cut away all hair and fibers.
• Check end caps: Spin the brush by hand. It should rotate freely. If stiff, replace the Main Brush.
• Inspect housing: Look for melted plastic or scorch marks inside the head. If present, the Motorized Floor Head may need replacement.
• Test briefly: After cleaning, reassemble and test for a short period. If smell returns quickly, replace the floor head.
