Built around a durable 223cc Powerease gas engine, this cold water pressure washer delivers an impressive 3,400 PSI at 2.5 GPM, giving you the power to cut through dirt, grime, algae, and buildup on surfaces like concrete, siding, decks, fencing, and more.

From weekend projects to serious property maintenance, this pressure washer is up to the task.

At the heart of the WJ3475PX is a 223cc Powerease OHV engine, known for its simple design, reliability, and strong performance across a wide range of equipment. Delivering 3,400 PSI of cleaning pressure, this engine powers through even the most stubborn stains, dirt, and surface contaminants—perfect for cleaning driveways, prepping decks for paint or stain, or blasting mold off fences and patios.

With a large-capacity fuel tank, you’ll get longer runtimes and fewer refills, giving you the flexibility to complete bigger jobs in one session.

This pressure washer is designed with everyday challenges in mind. Whether you're washing down stone paths, patio furniture, garden tools, or a car covered in road grime, the 2.5 gallons per minute of flow ensures efficient rinsing while the PSI rating provides aggressive cleaning performance when you need it.

Gas-powered operation means you’re not tethered to an outlet, and the machine is easy to roll into place for cleaning tasks across your property.

The WJ3475PX features a maintenance-free axial pump that delivers consistent water pressure without the need for frequent servicing. This high-efficiency pump also includes a built-in soap injector, allowing you to apply cleaning solutions through the system without any complicated attachments or adjustments.

Switch to the included soap nozzle, pull the trigger, and apply your detergent—ideal for cleaning vinyl siding, degreasing outdoor surfaces, or prepping vehicles for a spotless finish.

Keeping your machine running smoothly and safely is built into the design. The thermal relief valve activates if water gets too hot—relieving excess heat from the pump in the event you leave the trigger closed for too long. At the same time, the automatic low-oil shutdown system protects your engine from damage by shutting it down if oil drops below a safe level.

These features not only increase the lifespan of your equipment but also give you peace of mind while you work.

With a 35-foot high-pressure hose, the WJ3475PX gives you plenty of reach to work around buildings, large patios, vehicles, or decks without constantly moving the unit. The hose connects quickly using a quick-connect coupling system, making setup and teardown fast and frustration-free.

This pressure washer also includes four quick-connect spray nozzles—15°, 25°, 40°, and soap—so you can adjust your spray angle and pressure based on your cleaning needs. Whether you're hitting concrete with a narrow jet or rinsing siding with a wide fan, you’ve got the right tip for the job.

The included spray gun features a pistol grip handle with safety lock, giving you better control while preventing accidental discharge. The pressure washer is intuitive and easy to operate, making it accessible for homeowners while delivering performance that holds up under more demanding use.

With clear labeling and a straightforward layout, anyone with basic familiarity with outdoor equipment will find this machine quick to set up and use.

WetJet stands behind the WJ3475PX with a 3-year limited warranty, giving you confidence that your investment is protected.
