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

Safety: Remove the battery and detach the floor nozzle.

• 1. Verify brush rotation: With the vacuum reassembled and battery inserted, briefly run the unit and observe whether the brushroll spins. Stop and remove battery again.
• 2. Clean brushroll: Remove hair and fibers from the bristles.
• 3. Check bristle wear: If bristles are very short or flattened, replace the brushroll.
• 4. Inspect belt (if applicable): On belt-driven SilverCrest heads, check the belt for slack or cracks. Replace if worn.

After replacing worn parts, test pickup on carpet again.
