2. GPM (Gallons per Minute)
3. Engine Horsepower
4. Cleaning Units (CU)
5. Thermal Efficiency
6. Motor Type (Electric, Gas, Diesel)
7. Pump Type (Triplex, Axial)
8. Power Source (Electric vs. Fuel)
9. Consideration of Application Needs

The next section will explain these ratings and factors in detail for better understanding.

1. PSI (Pounds per Square Inch):
   PSI is a measure of water pressure and represents how forcefully water is delivered from the nozzle. Higher PSI ratings lead to cleaner surfaces faster. For most industrial applications, a PSI rating between 2500 and 4000 is typical. According to a study by the Association of Equipment Manufacturers (AEM), optimal PSI for heavy-duty cleaning is often above 3000.

2. GPM (Gallons per Minute):
   GPM indicates the volume of water that flows through the pressure washer. A machine with a high GPM can often clean surfaces more quickly because it delivers more water, effectively rinsing away dirt and grime. For industrial tasks, look for models with 3 to 5 GPM. Research by Equipment Today notes that GPM is crucial for efficient cleaning in large areas.
