10 Best Costco Pressure Washers 2025 in the United States

The Westinghouse WPX3200 Gas Pressure Washer is a robust and high-powered option, delivering 3200 PSI and 2.5 GPM, making it suitable for deep-cleaning tasks on various surfaces such as decks, sidewalks, siding, fences, and more. The gas-powered 212cc 4-stroke engine ensures strong and consistent performance, and the onboard 0.9-gallon soap tank enhances cleaning efficiency by allowing you to mix soap directly with the water flow. The five included quick-connect nozzles (0°, 15°, 25°, 40°, and soap) provide versatility in handling different cleaning needs, from tough stains to gentle rinsing. The 25-foot abrasion-resistant hose offers a decent reach, although some users might find it slightly short for larger areas.

Its heavy-duty steel frame and 12-inch never-flat wheels improve durability and mobility, making it easy to maneuver. However, at 72 pounds, it can be heavy to lift for some users. The manual choke might be less convenient compared to electric starters, but it is reliable. Additionally, the maintenance-free axial cam pump adds to the product's longevity. The pressure washer comes with a three-year limited warranty, providing peace of mind. Users should be aware that residual oil or fuel odor might be present due to factory testing, and proper storage and handling are essential to prevent leaks.

This pressure washer is ideal for homeowners and DIY enthusiasts looking for a powerful and versatile cleaning tool.

The Simpson Cleaning 3600 PSI Gas Pressure Washer is a strong choice for professionals and serious users who need a reliable, powerful machine. With 3600 PSI and 2.5 gallons per minute flow rate, it offers enough pressure and water volume to tackle tough cleaning jobs like decks, wood restoration, and general commercial work. Its gas-powered Honda GX200 engine is known for durability and easy starting, which means less hassle during longer tasks. The included MorFlex hose is long and resistant to kinks and abrasion, allowing good reach around your cleaning area. The unit also includes five quick-connect nozzles, ranging from a concentrated 0° spray to a gentler 40° spray and a soap applicator, giving versatility to handle different surface types safely.

Portability is decent thanks to the aluminum frame and 10-inch pneumatic tires, making it easier to move over uneven terrain compared to smaller units. However, at nearly 79 pounds, it is still somewhat heavy, so it’s better suited for users comfortable with moving larger equipment or those who mainly use it in semi-fixed locations. The aluminum frame adds corrosion resistance, increasing the machine’s lifespan, which is a big plus if you plan to use it frequently. Also, being gas-powered means regular fuel and maintenance checks are necessary.

This pressure washer is well-suited for contractors or homeowners needing professional-level power and durability but may be more than casual users require due to its size and weight.

The Simpson Cleaning 3400 PSI Gas Pressure Washer is a solid choice for homeowners needing a powerful and reliable machine for typical outdoor cleaning tasks like decks, patios, and siding. Its 3400 PSI pressure and 2.5 GPM flow rate provide strong cleaning performance, making it effective for removing dirt and prepping surfaces. The gas-powered 208 cc CRX engine ensures good power and mobility without the limits of cords. The 25-foot MorFlex hose is flexible and durable, offering decent reach, and the unit includes four quick-connect nozzle tips allowing for versatile spray options, including a soap nozzle to tackle different cleaning jobs.

The steel frame with a powder-coated finish and large pneumatic wheels help with durability and ease of movement over various terrains, which is helpful for yard work or uneven surfaces. On the downside, the pressure washer weighs 61 pounds, which is somewhat heavy, meaning it may require some effort to transport despite the wheels. Also, it’s designed mainly for residential use, so it may not be the best fit for more intense or professional tasks that require higher flow rates or specialized features.

This model offers a balanced combination of power, convenience, and build quality suitable for typical home use and serves as a dependable option for most household pressure washing needs.
