Cordless vacuum emits unusual vibrations or shaking during operation.

Safety first: Turn OFF and remove the battery before inspecting moving parts.

• Inspect brush roll: Remove the brush roll and clean off any clumps of hair or debris that could cause imbalance.
• Check for warping: Roll the brush on a flat surface. If it wobbles, it may be bent and should be replaced.
• Tighten screws: Check the brush head housing screws and tighten if loose.
• Test without head: Run the vacuum without the brush head attached. If vibration disappears, the issue is in the head. If it remains, the motor fan may be damaged and needs service.
