Cleaning Unit Ratio (CUR) in Pressure Washing & Power Washing
Why Does CUR Matter?
While high pressure (PSI) might seem like the holy grail of cleaning power, CUR reveals a deeper truth. It goes beyond brute force, showing how efficiently your pressure washer utilizes water to achieve cleaning results. A higher CUR indicates:
- More Cleaning Power per Drop: A higher CUR signifies your pressure washer gets more cleaning mileage out of every gallon of water, maximizing efficiency and potentially lowering your water bills.
- Reduced Environmental Impact: Lower water consumption translates to a smaller environmental footprint, making your cleaning routine more sustainable.
- Gentle on Surfaces: High pressure can damage delicate surfaces. A higher CUR often allows for lower pressure settings while still achieving effective cleaning, preserving your drivewayThe main access road to your property that pressure washing can clean and remove dirt, oil stains, and tire marks.

Decoding the CUR Formula: Numbers that Empower
Now, let’s unlock the secrets of the CUR formula:
CUR = GPM / PSI
- GPM (Gallons per MinuteGallons per Minute: This measurement indicates the amount of water flowing through the pressure washer per minute. Higher GPM means more water coverage, while lower GPM offers more concentrated cleaning. Related terms: Gallons per minute, pressure washer flow rate GPM, Pressure Washing & Power W...

- PSI (Pounds per Square InchPounds per Square Inch: This measurement indicates the force of the water coming out of the pressure washer. Think of it as the "power" of the spray. Related terms: Pounds per square inch, pressure rating, pressure level PSI, Pressure Washing & Power Washing PSI, or pounds per square inch, is a ... More): This measures the force of the water spray.
Essentially, CUR divides the cleaning force (PSI) by the water used (GPM) to reveal the efficiency ratio. A higher number indicates your pressure washer uses less water to achieve the same cleaning power, making it a champion of efficiency.
Choosing a Champion: CURs that Lead the Pack
While specific CUR values vary based on pressure washer models and intended uses, here’s a general guideline:
- CUR below 2: This indicates lower efficiency, often found in older or budget-friendly models.
- CUR between 2 and 4: This represents a good balance of cleaning power and efficiency, suitable for most residential cleaning tasks.
- CUR above 4: These are considered highly efficient models, ideal for professional cleaners or heavy-duty tasks.
Remember, CUR is just one factor to consider when choosing a pressure washer. However, prioritizing a higher CUR, along with appropriate PSI and features, can lead you to a machine that delivers powerful cleaning while minimizing water usage and environmental impact.
