The Greenworks
GPW1951 is part of the
Pressure Washers test program at
Consumer Reports. In our lab tests, Pressure Washers
models like the GPW1951 are rated on multiple criteria, such as those
listed below.
Cleaning:
A high score means the pressure washer cleans quickly and works well on a variety of surfaces. A top-scoring model handles everything from light tasks to deep cleaning with multiple spray nozzles.
Power:
A combination of pressure, measured in pounds per square inch (psi), and flow, measured in gallons per minute (gpm). A high score means that this model has a higher PSI and Flow rate relative to other models we've tested. A top-scoring model cleans surfaces more effectively and gets the job done faster.
Noise:
A high score means quieter operation. This score is a combination of measurements taken both close to the machine and at the end of the hose's reach. We strongly recommend hearing protection when working close to a pressure washer, especially gas-powered models that tend to be significantly louder than electric and battery-powered models.
