I’ve been using this washer for almost 2 months, and I’m thoroughly happy with my choice of product. It got much more power than I expected. I can’t stop finding uses for it. I’ve used it on our wood decking, and for moss removal on sidewalks and driveway. I even used it to remove rush from the underside of classic Plymouth!

I bought this pressure washer in June of 2022. I use this pressure washer extensively many times a month hours at a time. 2- 3 times a year I pressure wash my 2 story 2,200 sqft farm, plus a 900 sqft deck, numerous out buildings and their roof. Plus a huge 2-story barn and roof with 4,500 sqft of roof that needs cleaning twice a year. The list goes on... This machine as indicated gets plenty of use and has never let's me down. Soap Dispenser Tank works great but I did have issues trying to pump solution directly from a bottle instead of the tank. It was probably me. Overall I would highly recommend this pressure washer to everyone. Since it's been nearly 2 years since I bought this pressure washer before writing a review, I have plenty of experience in backing up what I put in my review.

The WPX3400 showed up two days after purchase. It took about 10 minutes to read the Quick Start Guide and then another 10 minutes to do the setup, which consisted of removing the well-packaged components (handle, sprayer, hose, mounting brackets, rubber foot) from the box and attaching them with simple tools (hex wrench and a couple nut drivers, not provided). In summary, I'm really amazed at the quality of this unit for the price.

This is overall well thought out and powerful. It is much more compact for storage than I was expecting. It has a great flow rate and pressure, so cleans much faster than an electric and makes a circular concrete cleaning attachment more effective. For some reason the pin that holds one of the wheel axles in place was missing or otherwise fell off. Within the first minute or two of using it, the axle vibrated out and the unit titled diagonally I shut it off. I'm working with warranty now and it sounds like I should get the missing part. I just used a wire in the meantime. The only other constructive feedback I have is that the soap tank opening is poorly placed and is obstructed my the pump. There is probably not a great place for it but providing a funnel that can compensate would be great. A normal funnel shape still doesn't help and an oil funnel that's a long shape that I had for my generator kind of worked with some difficultly.

As a mechanical engineer and product designer myself I tip my hat to the team at Westinghouse! The design was clearly thought through for functionality, features, ergonomics and the ease of assembly - although I did need a 13mm wrench and 4mm (or 5/32") hex key not mentioned in the instructions. No big deal. Everything is included except gasoline, and I had it together in no time. First impressions - besides the power - was how easily it starts, and how the large wheels give it great maneuverability. I actually expected it to be louder and more beastly, but it is well behaved while running and the large rubber foot at the front does a great job of keeping it in place while also absorbing vibration. My only critique is that a right angle fitting should have been used where the soap hose enters the pump, to prevent the hose from kinking. But overall this is a great machine that I expect will last for years.

I finally unboxed and used this now that it's warming up. Minimal assembly, and what there was is very easy. Started on the 2nd pull and did a fantastic job cleaning my driveway in conjunction with my separately purchased Westinghouse 15" surface cleaner. This is the first gas powered pressure washer I've owned and it runs circles around my old electric pressure washer. So far, I would highly recommend this product.

Just purchased but so far, great pressure washer, easy start and powerful spray. 2 faults both on ignition switch, 1) cheap plastic cover on wiring, broke during assembly 2) Very cheap ignition switch, this should have never passed quality control, I expect it to break soon and will need upgraded replacement.

I purchased this power washer so I could do my house as I got tired of paying someone else to do it. I'm not the most mechanically inclined person. It was easy to set up and operate. The tips are super easy to change and having the soap tank on the unit is a plus. Definitely going to be washing the house more frequently. Maybe my deck next.

Purchased a competitor’s electric one and returned it the next day! Then I ordered the Westinghouse WPX3400 and it was exactly what I was looking for. We stained our deck a dark solid stain, and every shoe / muddy paw print shows. The power washer cleaned the porch thoroughly along with the white siding on our house. I would definitely purchase it again if needed!

I have had this pressure washer for about a month and it works great. Plenty of power a soon as you squeeze the trigger. Used it to clean my driveway with the help of a Westinghouse surface cleaner and the results were fantastic. If you’re in the market for a pressure washer, get this brand. You will be pleased with the results!
