Safety first: Unplug the machine and allow it to cool before inspection.

Clean all filters: Remove and wash foam filters; replace any paper/HEPA filters if fitted and dirty.
Check for blockages: Inspect nozzle, hose, and internal ducts for clogs and clear them.
Service brush bar: Clean and ensure the brush bar spins freely. Replace if bearings are stiff.
Reduce duty cycle: Use the machine in shorter sessions with breaks to cool. If the problem persists, the motor may be failing and require replacement.
