Compared on paper

Specs such as CFM, PSI and torque are the manufacturer’s ratings as listed, collected 11 November 2026. Where a listing contradicts itself, the comparison says so rather than picking a figure.

How the points were given

Shop Scores range from a low of 9.2 to a high of 9.8, with each tool positioned by its weighted points proportionally, and more points always yields a higher score.

The Shop Score weighs the stated cleaning figures, the build, the value, the stated safety features and the warranty. A factor the listing does not state earns no points. How we pick explains the weights.

What the listings tell you

The listings state PSI and GPM separately, and no combined figure is stated, so the comparison uses the stated figures only. The SIMPSON PowerShot title states 3500 PSI while the bullets state 3300 PSI for the pump, and the bullets state 74 lb while the spec table states 72.8 pounds, so the listing does not settle either figure. The VEVOR listing states a 390 ml engine and a 15 hp copper pump, so the engine figure is unclear. The SIMPSON listings state 49-state compliance.

Buying guide: the best gas pressure washer

PSI and GPM

The VEVOR states 4400 PSI and 4.0 GPM, the highest figures here. The Evernexta states 3800 PSI and 2.7 GPM, the Genkins 3200 PSI and 2.5 GPM, and the SIMPSON Clean Machine 2900 PSI and 2.4 GPM. The SIMPSON PowerShot title states 3500 PSI while the bullets state 3300 PSI for the pump. Match the pressure to the surface, and check the listing before ordering.

Hoses and nozzles

The VEVOR hose is 50 ft, the Evernexta 35 ft, the Genkins 27 ft, and the SIMPSON washers 25 ft. All but the SIMPSON Clean Machine include 5 quick-connect nozzles; the SIMPSON Clean Machine includes 4 tips. The SIMPSON Clean Machine has a siphon hose for detergent from an external bucket, while the Evernexta and Genkins have onboard soap tanks.

Engines and pumps

The SIMPSON PowerShot runs a Honda GX200 engine with an AAA triplex pump. The SIMPSON Clean Machine runs a 170cc engine with an axial cam pump. The Evernexta and Genkins run 212cc engines with axial cam pumps. The VEVOR listing states a 390 ml engine and a 15 hp copper pump; the wording does not name the engine the way the other listings do, so the comparison takes the stated figures as listed.

Warranty

The SIMPSON Clean Machine states a 2-year limited engine warranty, a 1-year limited pump warranty, a 5-year limited frame warranty and a 90-day limited accessory warranty. The Evernexta states a 2-year manufacturer warranty. The SIMPSON PowerShot, Genkins and VEVOR state no warranty term.

Weight and storage

The VEVOR weighs 137.0 pounds, the SIMPSON PowerShot 74 lb per the bullets, the Evernexta 63.0 pounds and the SIMPSON Clean Machine 50 lb. The Genkins frame folds for storage. Check the wheels and the handle before moving a heavy washer.

Garage Fit Check

A gas pressure washer needs water, fuel and space: check the hose reach, the frame size and the storage room before ordering. The Genkins folds for storage, and the VEVOR weighs 137.0 pounds, so check the wheels and the handle before moving it.
