  • Powerful and Reliable – A Great Buy!
Style: 3400 Max PSI
I’m really impressed with the performance of this Westinghouse gas pressure washer. It has plenty of power to clean my driveway, deck, and siding with ease. The setup was straightforward, and it started up without any issues. The build quality feels solid, and I like the included nozzles for different spray options. It’s a great value for the price and makes outdoor cleaning jobs so much faster. Highly recommend! ... show more

  • Built Like a Tank. Gas > Electric. WPX3400 Proves It! Add the Surface Cleaner.
Style: 3400 Max PSI
The build quality of the Westinghouse WPX3400 is outstanding. After years of using an electric washer that couldn’t keep up, switching to gas completely changed the game. It effortlessly stripped away years of grime from my driveway, sidewalks, and patio—and even made our backyard turf look new again. The engine starts reliably, runs strong, and pairs perfectly with accessories. I picked up the Westinghouse surface cleaner as well, and it’s a game-changer—turning large cleaning jobs into quick, satisfying wins. Highly recommend bundling it if you’re considering this unit. Setup was intuitive, the construction feels rock solid, and thoughtful design touches—like onboard nozzle storage and a compact frame—make it easy to maneuver and store. Swapping between the surface cleaner and the wand for edge work was simple. I had a small leak at first, but a quick wrap of plumber’s tape solved it, and it’s been flawless ever since. Using this machine is genuinely satisfying. If you’re on the fence between gas and electric, this is your sign to go gas. Westinghouse nailed the power, performance, and reliability. ... show more

  • Westinghouse MPX3400. A pleasurable Experience and the Perfect Pressure Washer.
Style: 3400 Max PSI
Excellent, user friendly product from assembly thru safety and operational instructions. Very detailed information available. Washer started on the first pull! Lightweight, but sturdy and strong. Necessary attachments installed with ease.

  • Solid Performance and Easy Setup — Matched my expectations
Style: 3400 Max PSI
I’ve had the opportunity to use the WPX3400 extensively over the past weekend, and overall, it delivered a dependable experience. The product arrived well-packaged and undamaged. Assembly was very straightforward — it took minimal time and required only minimal tools (allen wrench and a few tools to hold/tighten bolts). Once assembled, I was able to start the engine with just one or two pulls consistently. I went from unboxing to completing nearly 10 hours of pressure washing over two days without any issues. The washer provided ample pressure for cleaning tough surfaces. I used it in conjunction with an 18-inch disc surface cleaner, and it handled patios, sidewalks, driveway and patio furniture. What initially influenced my purchase was seeing it rated #1 by a well known consumer products review source (C R), and my real-world use reflected that ranking. The pressure washer performed exactly as I had hoped based on that recommendation. If you're looking for a reliable option that requires little effort to get started and worked well through longer jobs, this one has proven itself capable. ... show more

  • Powerful, and very Sturdy!
Style: 3400 Max PSI
This is a very well built, sturdy pressure washer. I've used many in my lifetime, as well as hot pressure washers, and this is no toy! Pressure is amazing, and at 3400 PSI, that ranks with some of the best. Starts easily, anti vibration foot for stability, and color coded tips so you know what spray pattern you are getting. Rolls extremely easy. Just hang on when you pull the trigger for the first time. Comes complete with oil, and was relatively easy to put together. Has a screen in the gas tank, to keep the debris out, but please use clean gas with an anti-ethanol spritz in your can. Sold at Lowes, Home Depot, anywhere. Okay just a couple features kept it from a five star review. The soap tank fill top is set back,so filling from the gallon jug of soap,was a bit challenging, but a funnel with a flexible spout would work great.. Other issue is the spray hose. It needs a swivel to wrap it up neatly. If you have another person with you they can turn it while you wrap it. Takes longer than it should. Overall, I feel this is a great buy for the price!

  • The 5 star reviews are spot on - the WPX3400 is one excellent power washer!
Style: 3400 Max PSI
Just purchased the Westinghouse WPX3400 gas power washer after reading many Amazon reviews and other website reviews. Delivered about a month ago along with a few accessories including 16.5" surface cleaner, 50' pressure hose, short gun and foam cannon. All to complete my "Honey Do" list of cleaning the back concrete patio, pool area and veranda, front walk ways and cleaning the windows. My list included washing the F150, the farm truck and tractor along with tractor implements - bushwhacker, discer, box scraper and sprayers. It was a lot of pressure washing over the last month. Easy to assemble with well done instructions and illustrations - although you will need a few tools including metric wrenches and metric hex wrench to assemble (not included). Took me about 40 minutes to get it all unboxed and assembled, filling the oil reservoir and getting it gassed up and started on the second pull!. The WPX3400 is a super star pressure washer. Well made and constructed, intuitive/simple to use and powerful with the specific job's Westinghouse accessory. The Amazon reviews are accurate and worth reading along with the how to videos of this unit on YouTube. Highly recommended. The perfect pressure washer system for home use, farm use and DIY uses. ... show more
