1. Core Definition
 
• Brushed Polisher: Equipped with brushed DC motor (traditional carbon brush motor).
 
• Brushless Polisher: Adopts brushless DC motor (BLDC), no carbon brushes inside.
 
2. Main Differences
 
1) Service Life
 
• Brushed: Carbon brushes wear out over time, shorter lifespan.
 
• Brushless: No wearable brushes, far longer service life.
 
2) Heat & Energy Efficiency
 
• Brushed: More friction, higher heat, lower efficiency, higher power consumption.
 
• Brushless: Less friction, low heat generation, energy-saving & high efficiency.
 
3) Noise & Vibration
 
• Brushed: Obvious mechanical noise from brush friction.
 
• Brushless: Quieter running, smoother operation, less vibration.
 
4) Maintenance
 
• Brushed: Need regular replacement of worn carbon brushes.
 
• Brushless: Almost maintenance-free.
 
3. Application Suggestion
 
• Brushed: Daily light use, home DIY.
 
• Brushless: Professional long-hour work, auto detailing shops, frequent heavy-duty use.
