Vacuum leaves dust and debris on the floor even though the brush is spinning.

Safety first: Turn off and remove the battery.

• Remove the floor head and inspect the brush roller. If bristles are worn down or uneven, replace the brush roller.
• Check the suction channel behind the brush for blockages and clear any debris.
• Ensure the floor head neck and swivel joint are not cracked and that seals are intact.
• For hard floors, use the soft roller head if supplied; for carpets, use the bristle brush head.
• If pickup remains poor, replace the complete motorized floor brush assembly.
