Vacuum leaves debris on carpets; brush spins but pickup is poor.

Safety first: Remove the battery pack before working on the floor nozzle.

• 1. Clean brush roll: Remove the brush roll from the nozzle. Cut away hair and fibers. Clean the bristles thoroughly.
• 2. Check bristle wear: If the bristles are very short or flattened, replace the brush roll with a new Grundig brush compatible with your model.
• 3. Clear nozzle channel: Inspect the suction channel behind the brush roll and at the neck of the nozzle. Remove any compacted dust or objects.
• 4. Adjust cleaning mode: Use the appropriate power mode and, if available, carpet setting on the nozzle to improve pickup.
