The Simpson gas pressure washer tends to be one of the smaller units on the market, weighing approximately 65 pounds. It sits at a low level sideways position and is easier to store than other leading models. This unit sits on a steel frame with two 10 inch never-flat pneumatic wheels for easier mobility. Out of the box is also a 1/4 inch thick 25-foot hose that is resistant to kinks and abrasion.
This model has a Honda GC190 OHC engine with an output of 3100 PSI at around 2.5 gallons per minute. This was an easier washer to use than most because it features a safety trigger on the spray gun and has more control than other leading brands. The Simpson gas pressure washer has 5 interchangeable nozzles. This includes 0, 15, 25, and 40-degree tips for various tasks, as well as a chemical tip. All of this is stored onboard at the top of the unit for easy access and for keeping track of all the pieces with ease.
