10 Best Power Washers For Decks 2026 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 SIMPSON PowerShot PS60843 is a high-powered gas pressure washer designed especially for tough deck cleaning and other professional outdoor jobs. It offers a strong 4400 PSI pressure and a solid water flow rate of 4.0 GPM, which means it can handle stubborn dirt and grime efficiently. The gas engine ensures you get plenty of power without worrying about electrical outlets, making it convenient for bigger outdoor spaces. It comes with five nozzle tips (including a soap nozzle), allowing you to adjust the spray pattern for different cleaning tasks — from narrow and intense to wide and gentle.

The included 50-foot hose is long enough to reach most deck areas without constantly moving the unit, and it’s made to resist kinks and wear, which adds to durability. Though it weighs about 135 pounds, the sturdy steel frame with 13-inch pneumatic tires makes it easier to move around even uneven ground, an important factor if your deck is in a yard or rugged area. Some might find this unit a bit heavy compared to electric models, and since it’s gas-powered, you’ll need to handle fuel and maintenance. But its powerful pump with thermal relief helps prevent overheating during extended use.

For professionals or those serious about deep deck cleaning and restoration, this washer’s combination of power, nozzle versatility, and build quality makes it a reliable choice. It may be more machine than needed for casual or light deck cleaning, but it’s ready for demanding jobs.

The Greenworks 80V 3000 PSI Pressure Washer is a cordless, battery-powered machine offering strong cleaning performance with 3000 PSI pressure and a 2.0 GPM water flow rate. This level of power is sufficient to handle common outdoor tasks like cleaning decks, patios, driveways, and siding effectively. Its brushless motor and cast aluminum pump deliver reliable operation that outperforms some gas models, making it a good choice if you want the convenience of cordless use without sacrificing much power.

The included two 4.0Ah batteries and rapid charger help maintain portability, although the unit itself weighs around 64 pounds, which means it’s portable but not lightweight. The 25-foot steel braided hose is durable and kink-resistant, providing enough reach for most residential jobs. The variety of nozzle tips (15°, 25°, 40°, soap, and turbo) adds versatility for different cleaning needs, from gentle rinsing to tougher grime removal. An added bonus is its ability to draw water from various sources, not just a garden hose, which can be handy in some situations.

While it offers good pressure, the water flow rate is moderate, so it may take slightly longer to clean large or heavily soiled areas compared to higher GPM gas models. For those who prioritize portability and cordless operation without the mess of gas, this model suits homeowners looking to maintain decks and similar surfaces with decent power and flexibility.
