Simpson went above and beyond on this model, combining great components with a low cost! This model features a powerful Simpson 420cc Commercial Series engine and a triplex pump that delivers 4 GPM at 4400PSI! There isn't much under the sun you can't clean with those specs. The adjustable unloader lets you adapt to the job at hand without fuss, increasing or reducing PSI on demand. You won't find that on consumer models. The 13" pneumatic tires absorb vibration and are ready for construction-grade terrain. The triplex plunger pump design runs cooler and lasts longer than axial pumps, plus they can be rebuilt if you ever had an issue. All around, our favorite recommendation for this category.

Like all Easy Kleen pressure washers, this machine is a commercial-grade cleaning machine! With a commercial-grade 14 HP engine and a Commercial Duty 3.5GPM Triplex Pump, this unit with clean anything you could dream of with ease. Plus, the oil-fired burners provide 350,000 BTUs for fast heating! The 150-degree temp rise gives you the option to get tough stains removed without scrubbing or damaging the surface with high PSI. With the diesel-fired burner, you have a 10-quart tank with an adjustable thermostat to better control the temperature, too. Lastly, the electric start lets you begin with the touch of a button! (battery not included). Roll it around on its impossibly tough 12 gauge one-piece steel frame roll cage, and it may just be the last pressure washer you ever need.

What gives you top-of-the-line performance with no water supply on-site? This is the machine you need! This trailer-mounted washer is equipped with a Honda GX390 engine with an electric start, a Comet pump, and a burner for hot water washing performance that can't be beaten. You can take your water supply on-the-go with this 200-gallon tank. Once you park, you can rely on the garden and high-pressure hose reels on board to give you the cleaning range you need.
