10 Best Gas Power Washers 2025 in the United States

The Westinghouse WPX3800 is a robust gas-powered pressure washer delivering 3800 PSI and a water flow of 3.6 gallons per minute, making it strong enough for cleaning driveways, decks, cars, fences, and patio furniture. Its 274cc engine is a reliable 4-stroke that starts with a simple pull and requires little maintenance. The washer includes a useful 0.8-gallon onboard soap tank, which helps apply detergent effectively for tougher cleaning tasks. You get a 35-foot hose that allows good reach around your work area, plus five quick-connect nozzles providing different spray patterns (from a narrow 0° jet for tough spots to a wider 40° fan for gentle cleaning).

The frame is built of steel and mounted on large, never-flat wheels for easier movement despite the unit weighing 91 pounds. This makes it fairly portable for a machine of its size. Included are helpful extras like engine oil and a quick start guide to get you going right away. On the downside, the weight and size may be a bit much if you need something very lightweight or compact. While powerful, this model might be more than what’s needed for small or occasional tasks, and gas engines require more upkeep than electric ones.

Additionally, some users might find the fuel odor noticeable at first. If you have medium to heavy-duty cleaning needs around your home or vehicles and prefer the freedom of a gasoline engine without depending on outlets, this pressure washer delivers solid performance and flexibility.

The Westinghouse WPX3600 is a solid choice if you’re looking for a powerful gas pressure washer to handle a variety of household cleaning tasks like driveways, fences, cars, and patio furniture.

Its 212cc engine provides reliable power and is designed to be low maintenance, which is helpful if you prefer something durable without much fuss.

You get a useful 35-foot hose that gives you plenty of reach without dragging the machine around too much. The five quick-connect nozzles cover a good range of spray angles from a pinpoint 0° to a wide 40°, plus a soap nozzle for easy detergent application using the onboard 0.8-gallon soap tank. This built-in soap tank is convenient for adding cleaning solutions without extra attachments. Portability is decent thanks to the sturdy steel frame and large 12-inch never-flat wheels, making it easier to move around uneven surfaces. However, the unit weighs 79 pounds, so it might feel a bit heavy if you need to lift it frequently or transport it in smaller vehicles.

Some users might notice a slight fuel or oil smell initially, but this is common with new gas-powered equipment and fades over time. The pump is brass, which is a strong material for durability and longevity. A 3-year limited warranty adds peace of mind. This pressure washer balances solid power, useful accessories, and durability, making it a good fit for homeowners needing a reliable machine to tackle various outdoor cleaning jobs. It’s especially well-suited for users who want a machine ready to go with built-in soap application and multiple nozzle options, though keep in mind the weight if portability is a major concern.
