The Westinghouse WPX3400e is a powerful electric pressure washer designed for homeowners who need serious cleaning capability without the fumes of gas models. With 3400 max PSI and 2.0 GPM, it stands out among electric units, easily handling driveways, fences, siding, and patio furniture.
Its standout feature is the maintenance-free brushless motor and axial cam pump, which delivers consistent pressure and long life. The five quick-connect nozzles and onboard soap tank allow you to adjust from gentle washing to high-pressure stripping effortlessly. Real-world performance is excellent, with users reporting effective removal of mildew, dirt, and grime.
Build quality is robust, with a steel frame, 10-inch never-flat wheels, and a 35-foot GFCI cord for good reach. The 25-foot abrasion-resistant hose is flexible and durable. However, the hose length may limit some large projects without extension, and the unit is somewhat heavy to lift.
Potential drawbacks include reliance on an electrical outlet, which can be inconvenient for large properties. Also, the included wand may be a bit short for very high areas. But overall, the WPX3400e offers exceptional value for its power level.
Verdict: For homeowners seeking a reliable, high-performance electric pressure washer with minimal maintenance, the Westinghouse WPX3400e is a top choice. Its combination of power, versatility, and warranty makes it a smart investment.

Buying Guide
PSI and GPM Ratings
The cleaning power of a pressure washer depends on PSI (pounds per square inch) and GPM (gallons per minute). For surface cleaners, you need at least 3000 PSI and 2.5 GPM to spin the nozzles effectively. Higher ratings mean faster cleaning, but stay within your budget. Models like the Westinghouse WPX3400 gas unit offer 3400 PSI and 2.6 GPM, which is ideal for tough grime. If you prefer electric, the Westinghouse WPX3400e provides similar pressure with a brushless motor.
Surface Cleaner Size and Material
Surface cleaners come in sizes from 15 to 30 inches. Larger sizes cover more area per pass, but they need higher GPM to work. For most driveways, a 24-inch model is a good balance. Stainless steel housings last longer than plastic, especially with commercial use. The 3 NOZZLE JETS, Stainless Steel Power Washer and the Stainless Steel Power Washer Attachment both offer durable steel construction.
Portability and Ease of Use
Look for features like wheels, dual handles, and quick-connect fittings. Wheels make it easy to move across large surfaces without lifting. Dual handles give you better control and reduce fatigue. The with 4 Wheels,Stainless Steel Housing,4 and Stainless Steel Housing, 4 Wheels, Dual Handles are designed for easy rolling.

Compatibility with Your Pressure Washer
Most surface cleaners attach via a 3/8-inch quick-connect fitting and work with gas or electric pressure washers. Check the maximum PSI and GPM rating of the attachment to ensure it matches your machine. The Stainless Steel Driveway Cleaner for Power Washer handles up to 4500 PSI, making it versatile for many models. If you are buying a complete unit, the Westinghouse WPX3400 Gas Pressure Washer includes everything you need. For more buying advice, visit our zero turn mower buying guide.

Frequently Asked Questions
Can I use a surface cleaner with any pressure washer?
Most surface cleaners attach via a standard 3/8-inch quick-connect fitting and work with both gas and electric pressure washers. However, check the PSI and GPM ratings to ensure compatibility. Attachments rated for 4500 PSI will work with lower pressure machines, but they may not spin as effectively.
What size surface cleaner do I need for my driveway?
For a standard two-car driveway, a 24-inch surface cleaner is ideal as it covers a wide area without requiring excessive GPM. Larger 30-inch models clean faster but need a pressure washer with at least 4 GPM. Measure your driveway and consider your machine’s flow rate before choosing.
Is a gas or electric pressure washer better for surface cleaning in 2026?
Gas pressure washers typically offer higher PSI and GPM, making them better for large, heavily soiled areas. Electric models are quieter, lighter, and require less maintenance. For occasional use on patios and cars, an electric unit like the Westinghouse WPX3400e is sufficient. For frequent heavy-duty cleaning, a gas model is more reliable.
How do I maintain a pressure washer surface cleaner?
After each use, flush the surface cleaner with clean water to remove debris. Check the nozzles for clogs and replace them if worn. Store the unit in a dry place to prevent rust. Stainless steel models require less maintenance than plastic ones. For more tips, see our Pressure Washers category.
