I bought this pressure washer after considering a plethora of different makes and models, including the option of electric vs. gas powered. I am glad I chose gas, and I'm glad I chose this Westinghouse WPX3400. I chose gas because it is much more powerful than electric, and I chose Westinghouse because they have a decent reputation, and the WPX3400 because that was the best "Max Pressure to Cost" ratio. I have used at least a half-dozen different pressure washers, mostly gas-powered, but never owned my own. Now that I have a property that I need to maintain myself, I believe it was WELL WORTH the price of this machine to be able to take on the significant number of tasks and projects that would require a Pressure Washer. The assembly was simple. Just a couple nuts and bolts to screw in (clearly labeled in the manual with pictures), and the top handle just slides on - no tools or bolts required. Great design. Starting Up: I thought that this Pressure Washer was a little flaky on the VERY FIRST USE. It took several pulls to start, and it stalled out on me. However, EVERY USE after the first, it has started up on the FIRST PULL! Seriously. If you buy this, expect your first startup to be a little rocky, but just let it do its thing - it'll either stall or you'll power it down... After the first use, expect every single use to start on the first pull, every time. That's how good I feel about this machine, after a small sample size of uses (~20 times). CAVEAT: If you are going to own and care for a Pressure Washer, you need to understand how to do things the right way. What I wrote above, about this machine starting up smooth every single time (from the second use on), will only be true if you care for the machine correctly. First, get yourself some 4-stroke engine oil as well as some "pump protector". Both of these items should be in the single-digit dollar amount. You will want these on hand because at some point you will need to: 1. Add more oil (or change the oil), and 2. Clean it thoroughly and protect the engine if storing it for any length of time. Second, read the manual in entirety, it's not long. If you're one of those people who throws away the manual without glancing at it and says "I got this", nobody thinks you're cool, and you might miss a potential quirk unique to a machine that will ruin your investment if you don't know about it. I won't summarize the manual here but I will touch upon two key things you need to be sure of before buying/using a gas powered machine like this WPX3400. - Be liberal with the "sample oil" included inside the box. I'd say use about 3/4 of the entire bottle, if not more. Use the dipstick to check the fill reading, and keep adding a few pours until it's at the right fill. - Connect your garden hose to the outdoor spigot and run the water for a few minutes before connecting it to the WPX3400. You want the hose full of water and not have any air pockets spurting out. Once the flowing end of the hose is pouring solidly, turn the spigot back off. - With the spigot turned off, connect the other end of the hose to the WPX3400. Go back and turn the spigot back on. With water now flowing directly to the machine, follow the startup procedure written in the manual, the basics being: Turn Power On; Turn Fuel Valve to On Position; Make sure engine is in "Choke" position; and give the ripcord a solid tug. If it doesn't start by the fourth or fifth pull, turn the water off and reassess. A few other helpful tips: - Once you get the machine running for the first time, don't worry about a stall or some slight oil burn. You want that first use to be continuous water spraying for several minutes. - On each successive Power Washing Session - you ALWAYS want to have the water spraying out of the nozzle at all times. If you need to let go of the nozzle trigger for any reason, try to get your finger back on that trigger as soon as you can. Ideally, you want to be continuously spraying water from the nozzle the entire time you are washing. Yes, this might seem like a waste of fresh water, but this is how you care for your investment. Instead of letting go of the trigger, move the nozzle away from your target and spray at the ground or into the air, and keep doing so until you are ready to spray your target area again. - If you know that you'll need to stop spraying for longer than 20-30 seconds, STOP what you are doing and TURN THE ENGINE OFF. - That might sound a little crazy, but this will preserve the engine life and performance. - Don't ever leave the engine running without spraying through a pressurized nozzle for more than 30 seconds. - If you need to stop your work for longer than that, turn off the engine; move the fuel switch to off and the engine switch back to "choke", then turn the water off at the Spigot. Disconnect the hose from the WPX3400, then pull the trigger on the nozzle to release any remaining pressure. - Do not attempt to change the spray nozzle until you have released all pressure.

I bought this dress for my bridal shower and it was absolutely stunning ! I received so many compliments !Reviewed in the United States on May 3, 2025

I just got the Westinghouse WPX3400, and I have to say—this thing seriously impressed me right out of the box. First off, assembly was quick and easy. Everything felt solid and well-built, and I was up and running in no time. The 212cc OHV engine fires up super smoothly—literally started on the second pull. It’s got power, and you can feel it right away. At 3400 PSI and 2.6 GPM, this washer has more than enough muscle to tackle anything you throw at it. I tried it on concrete that hadn’t been cleaned in years, and it brought it back to life. Fence, siding, patio furniture—it handled it all without bogging down. The included nozzles make it easy to switch between wide sprays and pinpoint pressure. One thing I really like is the built-in soap tank. Makes applying detergent effortless, and the switch from soap to water is seamless. Also, the hose storage and the onboard nozzle holder are convenient touches that keep things tidy. The build quality is top-notch. Heavy-duty wheels, a strong metal frame, and solid fittings everywhere. It doesn’t feel cheap at all—it feels like a tool you’ll have for years. If you’re looking for a reliable, powerful, and easy-to-use gas pressure washer, the WPX3400 is a beast. I’m honestly excited to keep finding things around the house to clean with it. Westinghouse knocked it out of the park with this one.

I don’t usually leave reviews, but this setup is just too good not to share. I bought the Westinghouse 3400 PSI Gas Pressure Washer along with the Westinghouse Surface Cleaner, and added a 25-foot extension hose and the Erie Tools 4,000 PSI Rotating Turbo Nozzle (3.0 orifice, 3.0 GPM)—and together, this setup crushed it. Pressure Washer: The Westinghouse 3400 PSI is a beast. It started on the first pull, and the power output is more than enough to deep clean everything from driveways and sidewalks to siding and patio furniture. Build quality is rock solid, and the included quick-connect nozzles are great for different tasks. Surface Cleaner: This attachment is a total game-changer. It cut my cleaning time in half and left a perfect, streak-free finish on my driveway and back patio. It’s smooth, easy to maneuver, and makes large flat surfaces almost fun to clean. Add-ons that took it to the next level: • 25-foot extension hose: This gave me the reach to do the entire front of the house and driveway without constantly moving the unit. Huge convenience boost. • Erie Tools Turbo Nozzle: This thing is incredible. It tore through caked-on grime and algae like it was nothing. Great for tough spots where the surface cleaner or standard nozzles weren’t cutting it. Final thoughts: This combo gives professional-level results for a fraction of the cost. If you’re considering a pressure washer setup that can handle serious jobs with ease, this is it. Just get the surface cleaner, extension hose, and turbo nozzle—you won’t regret it.

Started second pull and very fast compared to my old 1.7 gal electric one. Have to admit it does drink gas, about one full tank in an hour. But works well and did the job in one third the time. Now stored for the winter.

I bought the Westinghouse WPX2700 PSI in December 2022, but it's been too cold here in Ontario to use it yet. Westinghouse is a great company so I know there will be no issues with the machine come the spring when I will need it. It was very easy to assemble and is great value for money. I'm sure it will be easy to use also but having not used it, I can't give it 5 stars yet for ease of use.
