Possible Causes

Overloaded battery due to clogged airflow, Internal battery resistance increase with age, Shorted wiring or connector, Prolonged MAX/Boost use

How to Fix / Troubleshooting

Safety first: If the battery is extremely hot, turn OFF the vacuum, remove the battery, and allow it to cool on a non‑flammable surface. Do not charge a hot battery.

  • 1. Reduce load: Clean all filters and clear any clogs to reduce motor load.
  • 2. Limit MAX/Boost use: Use high‑power modes only when necessary and for short periods.
  • 3. Monitor temperature: After cleaning, run the vacuum and periodically check the battery temperature. Warm is normal; very hot is not.
  • 4. Replace aging battery: If the battery overheats quickly even under light use, replace it with a new genuine Shark battery.
  • 5. Inspect for wiring damage: If you notice melted plastic or burning smell near the handle, stop using the vacuum and seek professional repair.
