The inclusion of multiple nozzles (15°, 25°, 40°, soap, and turbo) adds versatility to tackle different surfaces and dirt levels. The heavy-duty cast aluminum axial cam pump delivers performance comparable to gas-powered models, while the JettFlow technology significantly enhances water flow, aiding in quicker and more efficient cleaning.

This pressure washer is also PWMA certified, ensuring that its PSI and GPM claims are verified by an independent lab. At a weight of 51.7 pounds, it might be cumbersome for some users to transport and handle. It is an excellent option for homeowners looking for a powerful and versatile electric pressure washer that combines strong performance with ease of use.

The gas-powered 212cc 4-stroke engine ensures strong and consistent performance, and the onboard 0.9-gallon soap tank enhances cleaning efficiency by allowing you to mix soap directly with the water flow. The five included quick-connect nozzles (0°, 15°, 25°, 40°, and soap) provide versatility in handling different cleaning needs, from tough stains to gentle rinsing. The 25-foot abrasion-resistant hose offers a decent reach, although some users might find it slightly short for larger areas.

Its heavy-duty steel frame and 12-inch never-flat wheels improve durability and mobility, making it easy to maneuver. However, at 72 pounds, it can be heavy to lift for some users.

The Simpson Cleaning 3600 PSI Gas Pressure Washer is a strong choice for professionals and serious users who need a reliable, powerful machine. With 3600 PSI and 2.5 gallons per minute flow rate, it offers enough pressure and water volume to tackle tough cleaning jobs like decks, wood restoration, and general commercial work. Its gas-powered Honda GX200 engine is known for durability and easy starting, which means less hassle during longer tasks. The included MorFlex hose is long and resistant to kinks and abrasion, allowing good reach around your cleaning area. The unit also includes five quick-connect nozzles, ranging from a concentrated 0° spray to a gentler 40° spray and a soap applicator, giving versatility to handle different surface types safely.

Portability is decent thanks to the aluminum frame and 10-inch pneumatic tires, making it easier to move over uneven terrain compared to smaller units. However, at nearly 79 pounds, it is still somewhat heavy, so it’s better suited for users comfortable with moving larger equipment or those who mainly use it in semi-fixed locations. The aluminum frame adds corrosion resistance, increasing the machine’s lifespan, which is a big plus if you plan to use it frequently. Also, being gas-powered means regular fuel and maintenance checks are necessary.

This pressure washer is well-suited for contractors or homeowners needing professional-level power and durability but may be more than casual users require due to its size and weight.
