Vacuum stops and shows a hot battery icon or message such as 'Battery too hot'; body feels warm after heavy use.

Safety: If the battery feels very hot, place the machine on a non‑flammable surface away from direct sunlight. Do not attempt to cool with water or place in a refrigerator.

• Allow to cool: Leave the vacuum switched off and disconnected from the charger for at least 1 hour to cool to room temperature.
• Check airflow: Clean filters and clear any blockages to reduce load on the motor and battery.
• Use lower power mode: Avoid continuous Max/Boost use; switch to Eco/Normal for general cleaning.
• Environmental conditions: Do not use or charge the vacuum in very hot environments (e.g., in direct sun, near heaters).
• Battery replacement: If overheating warnings occur frequently under normal use, replace the battery pack. Persistent overheating after battery replacement may indicate a motor or control board fault requiring service.
