Vacuum leaves debris on carpet even though suction seems strong

Safety: Remove the battery and detach the nozzle.

• Inspect bristles: Check if the brush bristles are worn down or uneven. Replace the brushroll if bristles are flattened.
• Clean nozzle: Remove debris from the nozzle intake and air channels.
• Verify brushroll rotation: Reattach the nozzle and run the vacuum. Confirm the brushroll spins at full speed and does not stop easily when lightly touched with a tool (do not use fingers).
• Replace worn parts: If bristles are worn or the motor is weak, replace the brushroll or nozzle assembly.
