10 Best Power Washers For Decks 2025 in the United States

The Westinghouse ePX3100 Electric Pressure Washer is a solid choice for those seeking a reliable and efficient power washer for cleaning decks. With a maximum pressure of 2300 PSI and a water flow rate of up to 1.76 GPM, it provides strong cleaning power, essential for tackling tough grime and dirt on decks. The inclusion of five different nozzles (ranging from 0 to 25 degrees, turbo, and soap applicator) allows for versatile cleaning applications, ensuring you can adjust the spray pattern to suit various surfaces and cleaning needs.

Additionally, the 25-foot nylon-braided hose offers decent reach, reducing the need to constantly move the unit around while cleaning larger areas. The onboard soap tank is convenient for applying detergents, enhancing its cleaning efficiency for heavily soiled surfaces like decks, driveways, and patios. Portability is a notable strength, as the unit is lightweight at 19 pounds and features a compact design with four quick-lock wheels and anti-tipping technology, making it easy to maneuver and store.

The auto-stop function when the trigger is not engaged is a thoughtful feature that conserves energy and prolongs the pump and motor life. However, it's worth noting that the pressure and flow rate might vary depending on the nozzle used, which could affect its performance. While the 25-foot hose is sufficient for most uses, some users might find it limiting if working on larger or more spread-out decks. The electric power source is convenient for consistent use, though it does require access to a power outlet. Covered by a 3-year limited warranty and backed by robust customer service, the Westinghouse ePX3100 offers peace of mind and value for money. It is a suitable option for homeowners looking for an effective, portable, and versatile power washer to maintain their decks and other outdoor surfaces.

The Greenworks Pro Brushless 3000 PSI Electric Pressure Washer is a powerful tool for cleaning decks and outdoor surfaces. With a pressure rating of 3000 PSI and a water flow rate of 2.0 GPM, it delivers strong and efficient cleaning performance. The TruBrushless motor ensures durability and reliability, while the PWMA certification guarantees that the pressure and flow rate have been independently verified.

The heavy-duty cast aluminum axial cam pump offers better-than-gas performance, making it a robust option for tough cleaning tasks. Additionally, the JettFlow technology enhances water flow, allowing you to reach higher areas and rinse quickly. The pressure washer comes with a 25-foot kink-resistant hose and a 35-foot GFCI power cord, providing ample reach for most cleaning jobs.

It includes a variety of nozzles (15°, 25°, 40°, soap, and turbo) to cater to different cleaning needs. The rugged steel frame design adds to its durability, though its weight of 51.7 pounds may make it less portable compared to lighter models. This electric pressure washer is a great choice for homeowners looking for high performance and reliability for their deck cleaning needs, though they should be prepared for its relatively heavier build.

The Sun Joe SPX3000 is a solid choice for anyone looking to clean decks and outdoor surfaces with ease. It delivers a strong 2030 PSI pressure and 1.76 gallons per minute (GPM) water flow, which is enough power to remove dirt, grime, and mildew without damaging wood surfaces. Its corded electric power source means you won’t have to worry about gas or battery life, providing consistent performance, though it does limit mobility to areas near outlets unless you use an extension.

The washer comes with five different quick-connect nozzles, including a soap applicator, giving you flexibility for different cleaning tasks — from a narrow, high-pressure stream to a gentle spray for delicate areas. It also has dual detergent tanks, so you can switch between cleaning solutions easily, which adds convenience for tough stains or different surface types. The 20-foot hose provides decent reach, though some users might find it a bit short for larger yards or decks, and the 24-pound weight makes it manageable to move but not ultra-lightweight. Its sturdy construction with brass fittings and stainless steel lance suggests good durability for regular use.

This model balances power and versatility well for most homeowners wanting to keep their decks and outdoor furniture clean without fuss, though those needing very high pressure or longer hose length might prefer other options.
