Vacuum leaves lines of debris behind and does not pick up well from carpets

Safety first: Turn off and remove the battery.

Improve pickup:

• Inspect the brushroll bristles. If they are worn down, uneven, or very soft, replace the brushroll.
• Check the floorhead for blockages in the suction channel behind the brushroll.
• Ensure the floorhead is set to the correct mode for carpet (if your model has a hard floor/carpet selector).
• Test the brushroll rotation on carpet; if it slows significantly or stops, the motor may be weak and the floorhead assembly should be replaced.

Warning: Using a worn brushroll can overwork the motor and reduce cleaning performance significantly.
