Whether working on an industrial job site, farm, or house, you need a pressure washer that gets the job done. This is why we test every SIMPSON® pressure washer to ensure it meets our strict performance guidelines before leaving our manufacturing plants. We even manufacture our frames, pumps, engines, hoses, and accessories to give our machines a performance edge over others in the industry.

Did you know we are the world’s leading manufacturer of pressure washer hoses? We have produced over 500 million feet of hose in the last ten years. That is enough to wrap around the earth nearly four times!

SIMPSON® was founded on an innovation in 1961 when Jack Simpson created the first 700-PSI gasoline-powered mobile pressure washer. Since then, we have made many industry firsts, including a remotely controlled inline chemical injector, an automatic pressure relief valve, a block-style unloader with an integrated pressure-activated valve system, and the first portable pressure washer capable of producing 5000 PSI. We are driven to create new technologies that allow you to get the job done easier, faster, and better than ever before.

Did you know that in 2006 we created a technology that prevents our high-pressure hoses from scuffing or marring surfaces they come into contact with? This innovation improved the industry standard of hoses included with most pressure washers sold today.

There is something very satisfying about cleaning dirty things by powering away dirt, grease, and grime with a pressure washer. We understand that satisfaction and strive to make the experience of using a SIMPSON® pressure washer the best it can be. This means making the best machines we can, answering your questions, and listening to your feedback so we can continually improve.
