Do I need a California-compliant pressure washer?

Yes. If you are using your pressure washer in California, it must be CARB compliant. California law requires that all pressure washers sold and operated in the state to adhere to strict emission standards set by the California Air Resources Board (CARB). The use of non-compliant equipment is subject to fines and confiscation by authorities. Purchasing a non-compliant pressure washer outside of California is not an option if you intend to use it in the state, as it will also need to be CARB compliant. PCE carries a complete line of CARB and EPA compliant pressure washers ready to go right out of the box and stay on the road. To learn all about California compliance, check your equipment, learn more about CARB and what they require, shop all compliant models, and even learn about financing options available to you, head to our California-Compliant Pressure Washers page.

About brand

Clarke – A Legacy of Innovation in Commercial Cleaning

Clarke began in 1916 when Alex A. Clarke built a faster sanding machine for bars and school desks. Soon after, demand grew rapidly, leading Clarke to develop a full line of sanding, vacuuming, and cleaning equipment. Over time, this early success laid the groundwork for a trusted brand known for durability and innovation in floor care. PCE Clarke Logo Nilfisk

As the company expanded through the 1920s and 1930s, so did its reputation for performance. By the 1950s, Clarke introduced major innovations—including the first battery-powered scrubber and the rugged Clarke Floor Maintainer. Additionally, continued product development throughout the decades fueled strong growth, making Clarke a commercial cleaning leader. Eventually, Clarke joined ALTO U.S. Inc., further expanding its global presence.

Today, Clarke operates under Nilfisk, one of the world's top cleaning equipment manufacturers. With this partnership, Clarke continues delivering reliable machines that are built to last. Furthermore, the brand remains focused on innovation, sustainability, and user comfort. From classrooms to commercial facilities, Clarke empowers professionals to clean faster, easier, and more effectively—every single day.
