What are the best gas pressure washers?
1. Simpson PS3228: best overall
The PS3228 pairs a Honda GX200 engine with an AAA triplex pump and a 25 ft hose. It makes 3,300 PSI at 2.5 GPM. Talk of the House named it best overall, and Forbes listed it as its best gas option. It has no onboard soap tank, so you will need a siphon tube or a foam cannon for detergent. It is heavy at about 75 lb.
2. Simpson 3,400 PSI Clean Machine: best for driveways
This 3,400 PSI, 2.5 GPM unit uses a CRX 208cc engine and weighs about 64 lb. Bob Vila picked it as best overall and noted that it includes a surface cleaner, which speeds up flat concrete. Street prices are reported around $350 to $400. There is no soap tank.

DeWalt’s gas model delivers 3,300 PSI at 2.4 GPM from a 208cc DeWalt engine and an axial pump. It weighs 64 lb and carries a 5-year frame warranty. Talk of the House called it the best value pick.
4. Westinghouse WPX3200: best budget
The WPX3200 offers 3,200 PSI and 2.5 GPM at 63 lb, typically priced around $320 to $380. It suits homeowners who want strong pressure without paying for a triplex pump.
5. Westinghouse WPX3800: most powerful in this list
With 3,800 PSI, 3.6 GPM, a triplex pump and a 35 ft hose, the WPX3800 is built for larger jobs. It runs about 2.5 hours per tank, weighs 91 lb, and sells for roughly $500 to $700.
6. Vevor 3,600 PSI: best onboard detergent tank
Vevor’s 3,600 PSI, 2.6 GPM model weighs 58.2 lb, includes an onboard detergent tank and sits around $300 to $350. Reviewers note the fuel lines may need upgrading over time.
How do you choose a gas pressure washer?
- Pump type: triplex pumps are quoted at 1,000+ hours, axial pumps at 200 to 500 hours.
- Engine: look for a four-stroke engine from a known maker such as Honda.
- PSI: 2,500 to 3,000 covers concrete; go 3,800+ for commercial work.
- Noise: expect roughly 85 to 100 dB, so wear hearing protection.
- Upkeep: budget about $30 to $50 a year for oil, fuel stabiliser and spark plug care.
Common mistakes when buying a gas pressure washer
Buyers often chase the highest PSI and ignore GPM, which controls how fast you rinse. They also forget that a heavier unit is harder to move around a yard. Finally, many skip winter storage steps, which shortens pump life. Read our guides on how to use a pressure washer before your first job.
Frequently asked questions
Is a gas pressure washer better than electric?
Gas models usually deliver more pressure and flow, so they clean concrete and large areas faster. Electric models are lighter, quieter and need less upkeep. Pick gas for big jobs and electric for cars, patios and small decks.
How much PSI do I need for concrete?
Sources we reviewed put driveways and concrete at roughly 2,500 to 3,000 PSI. Commercial-style work is placed at 3,800 PSI and above.
Triplex or axial pump?
Triplex pumps are reported to last around 1,000 hours or more, while axial pumps are quoted at about 200 to 500 hours. Axial pumps cost less, so they suit occasional home use.
What fuel does a gas pressure washer use?
Regular unleaded gasoline is the usual recommendation. Check your manual and avoid old fuel that has sat for months.
Final verdict
Choose the Simpson PS3228 if you want a proven engine and pump. Choose the DeWalt for value, the Westinghouse WPX3200 for budget, and the WPX3800 if you need serious flow. If your jobs are small, an electric model is easier to live with.
