Pressure Washer Power and Performance

When it comes to pressure washers, power and performance are essential factors to consider. The effectiveness of a pressure washer largely depends on its water pressure and water flow. Let’s take a closer look at these two components.

What Matters Most In A Pressure Washer?

Water Pressure

Water pressure refers to the force of water that the pressure washer can generate. This force is measured in pounds per square inch (PSI). The higher the PSI, the greater the force and the more effective the pressure washer will be at removing dirt and grime. Higher water pressure is especially important for tackling tough cleaning tasks, such as removing oil stains from driveways or moss from outdoor surfaces.

Water Flow

While water pressure is significant, water flow is equally important. Water flow is measured in gallons per minute (GPM) and refers to the amount of water that the pressure washer can deliver in a minute. A higher GPM means more water is being delivered, which can help rinse away debris and efficiently clean large areas. A balance between water pressure and water flow is necessary for optimal cleaning performance.


To determine the overall power and performance of a pressure washer, it’s crucial to consider both the PSI and GPM ratings. While a high PSI rating indicates strong water pressure, a high GPM rating ensures adequate water flow. For most household cleaning tasks, a pressure washer with a PSI between 1500 and 3000 and a GPM between 1.5 and 2.5 is sufficient. However, for more demanding jobs, such as commercial or industrial cleaning, higher PSI and GPM ratings may be required.

Motor Power

The motor power of a pressure washer directly affects its performance. A more powerful motor can generate higher water pressure and deliver greater water flow. Therefore, when choosing a pressure washer, consider the horsepower (HP) or amps (A) of the motor. A higher HP or A rating indicates a more robust motor and, consequently, better cleaning capabilities. It’s important to find the right balance of motor power based on your cleaning needs.

Cleaning Power

The combination of water pressure, water flow, and motor power determines the overall cleaning power of a pressure washer. Cleaning power, often measured in cleaning units (CU), is calculated by multiplying the PSI by the GPM. The higher the CU, the more effective the pressure washer is at tackling tough dirt and grime. Consider the cleaning power of a pressure washer to ensure it can handle the cleaning tasks you have in mind.
