Specs: Power, Weight, and Flow
Maximum Pressure
The NorthStar model delivers 4200 PSI of maximum pressure, while the SIMPSON PowerShot provides 3300 PSI. Higher pressure generally means more force to strip away stubborn grime, paint, or deep-set dirt from hard surfaces like concrete driveways or brick walls. If your primary goal is tackling heavy-duty cleaning jobs that require intense force, the NorthStar has a clear advantage in raw power output. The SIMPSON unit is still capable for many tasks, but the difference in PSI is significant for tough stains.
Flow Rate
Water flow rate is measured in gallons per minute, and the NorthStar offers 3.5 GPM compared to the SIMPSON’s 2.5 GPM. Higher flow rate helps rinse away debris faster and can improve cleaning speed on large areas. The NorthStar moves more water, which can make washing decks or fences quicker. The SIMPSON unit has a lower flow rate, which might require more time to rinse off loose dirt. For projects where rinsing speed matters, the NorthStar’s higher GPM is beneficial.
Weight and Mobility
The NorthStar weighs 175 pounds, whereas the SIMPSON PowerShot weighs only 74.8 pounds. This is a substantial difference in portability. The lighter SIMPSON unit is much easier to lift into a truck bed or move around a job site. It also features 10-inch pneumatic tires for smooth rolling over gravel and grass. The NorthStar is significantly heavier, which may make it harder to transport manually. If you need to move the machine frequently, the SIMPSON is the more practical choice.
Included Nozzles
The SIMPSON PowerShot comes with five quick-connect nozzle tips, including 0°, 15°, 25°, 40°, and a soap nozzle. This variety allows you to switch between stripping paint, cleaning cars, and applying detergent without needing extra purchases. The NorthStar data does not list specific included nozzle counts or types. Having a complete set of tips ready to use is convenient for varied tasks. The SIMPSON provides a broader range of spray patterns out of the box.
Hose Length
The SIMPSON PowerShot includes a 25-foot high-pressure hose that resists kinks and abrasion. This length provides decent reach for most residential tasks without needing extensions. The NorthStar specifications do not mention the included hose length. A known hose length helps you plan your workspace and determine if you need additional hose reels or extensions. The SIMPSON’s included 25-foot hose is a defined feature, while the NorthStar’s reach remains unspecified in the provided data.
