How to Fix / Troubleshooting

Safety first: Immediately switch OFF the vacuum, remove the battery, and do not continue to use it until the cause is identified.

  • 1. Check Electrobrush: Remove the floorhead and inspect the brush roller for jams. Clear all debris and ensure it spins freely.
  • 2. Smell source: Carefully smell near the floorhead and motor unit (with battery removed). Identify which area the odor comes from.
  • 3. Inspect for discoloration: Look for melted plastic, burn marks, or deformed parts.
  • 4. Do not ignore persistent smell: If the burning smell returns after cleaning, stop using the vacuum and contact Miele service. Internal electrical faults require professional repair.
