What products and equipment do you sell?

We have everything you need for professional pressure cleaning, including pressure washers for residential and commercial cleaning, surface cleaners for driveways, patios and decks, hoses, nozzles, guns, reels, pumps and accessories. We also custom build pressure cleaning trailers and skids to your exact specifications. All of our products are professional-grade and used by contractors, detailers and cleaning professionals across the country.

Do you build custom pressure cleaning trailers or skids?

Yep, we do. Our team of experts can design and build custom pressure cleaning trailers and skids that are tailor-made to your specific business requirements. You can choose your tank size and capacity, pump power and pressure rating, hose reel configuration and more. We'll build everything into a rugged, easy-to-use setup that is mounted on a trailer (or skid if you're on-site) and ready to go wherever you need to do your cleaning.

Can I finance my purchase?

Yes, you can. We've partnered with ClickLease to make financing simple and flexible for your equipment purchases. You can get instant approval and choose from customized payment plans for pressure washers, trailers, and other equipment, allowing you to equip your business with what you need without impacting your cash flow. You can also select Affirm or Klarna during checkout for smaller purchases, making it even easier to pay over time.

Do you offer technical support or setup assistance?

We can offer personalized product recommendations, setup and configuration assistance, technical support to help you troubleshoot problems and the answers to any and all operational questions. You can reach our experts anytime via phone, chat or email for fast, effective support.

What is your return and refund policy?

Most new unopened merchandise is returnable within 30 days of delivery. Contact us prior to shipping any merchandise back to us for a Return Material Authorization (RMA). All returned merchandise must be shipped via UPS or FedEx. Shipping charges paid on the original order are non-refundable unless the merchandise is defective. Customers pay all return shipping charges. Opened, unused merchandise may also be returned within 30 days of delivery if in like-new condition, subject to a 25% restocking fee. Once fuel or oil is added to engine-powered equipment, it is considered used and is not returnable. Returns are not accepted on custom and special order products. Orders that have shipped can not be cancelled, and may be subject to an Order Return Fee if refused. Please see our Return & Refund Policy for more details.

What payment methods do you accept?

We accept all major credit and debit cards, including Visa, MasterCard, American Express, and Discover. You can also pay easily and securely using Google Pay, Apple Pay, or PayPal at checkout. We have flexible financing options available through Affirm and Klarna, and for larger business equipment orders, financing is available through our partner ClickLease.

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.
