Vacuum runs for a while, then suddenly stops and will not restart until cooled, with no explicit error code.

Safety first: Turn OFF the vacuum and allow it to cool fully before further use.

• Deep clean airflow system: Thoroughly clean the dust bin, cyclone, wand, nozzle, and all filters to restore maximum airflow.
• Short test runs: After cleaning, run the vacuum for short intervals and monitor for heat buildup.
• Check environment: Avoid using the vacuum in very hot rooms or in direct sunlight for extended periods.
• Service motor if needed: If the vacuum still shuts down prematurely with clean filters and normal ambient temperature, the motor or thermal sensor may be failing and should be replaced.
