Key Specifications: PSI, GPM, and Cleaning Units

When choosing a commercial or industrial pressure washer, it is important to understand the major performance specifications to be able to select the equipment that fits the cleaning needs. PSI, GPM and Cleaning Units are the three most significant specifications to consider. Collectively, these measures define the degree to which a pressure washer will be powerful, efficient and productive in the actual practice.

PSI (Pounds per Square Inch)

• Determines cleaning force
• Higher PSI removes tougher contaminants
• Industrial units often exceed 4,000 PSI

GPM (Gallons Per Minute)

• Controls rinsing speed and coverage
• Higher GPM cleans larger areas faster
• Industrial washers typically range from 4–10+ GPM

Cleaning Units (CU)

• PSI × GPM = Cleaning Units
• Provides a balanced measure of performance
• Higher CU equals faster and more effective cleaning

For industrial applications, GPM often matters more than PSI for productivity.
