Simpson PowerShot PS4033 Gas Pressure Washer Review
The Simpson PowerShot PS4033 is part of the Pressure washer test program. In our lab tests, Pressure washer models like the Simpson PowerShot PS4033 are rated on multiple criteria, such as those listed below.
Cleaning: Versatility and efficiency in cleaning a range of surfaces. The better performers have multiple spray patterns that can cover various cleaning chores, from light, superficial cleaning to deep cleaning of concrete, decking, and other hard-to-clean surfaces.
Power: A combination of pressure, measured in pounds per square inch (psi), and flow, measured in gallons per minute (gpm). Higher pressure results in better cleaning of a given surface; coupled with a higher flow as well, you’ll get the job done the fastest.
Noise: A combination of measurements, based on dBA, reflecting the proximity of the operator to the pressure washer. While our Noise score averages measurements taken close by the machine and at the end of the hose’s typical reach, we strongly strongly recommend hearing protection for working close by a gas powered pressure washer in particular.
