I just purchased so I don’t have a use review yet. But from doing my research, putting the pressure washer together-which was a breeze I am happy with my purchase. The unit looks and seems well made. I’m looking forward to using tomorrow on my patio and my house siding.

I did a lot of research on gas powered pressure washers before deciding on the WPX 3400. Just assembled it and did a quick test and it performed as expected. Assembly is easy and only need to install the handle, hose and wand, and add engine oil.For the price it appears to be reasonably well made. Lots of plastic but competitors units at similar price point also have plastic parts. I hope that with proper care and relatively infrequent use I can get it to last for at least 300 engine run hours.

I have loved this product. I was enjoying the use of this WPX3400 gas pressure washer this summer. I was unable to use it last summer due to health issues. Now I need to figure out while it won't continue to run for more than a few minutes. I'm hoping it can be fixed. I changed the oil but there is more wrong than that.

cleaned my entire 1400 square foot patio in one weekend. Only had to fill up gas a few times so this engine runs smooth and efficient. Starts right up each time with minimal effort. Some minor assembly required but that took only a few minutes. Patio looks as good as it did 10 years ago. All gas power washers are a loud but this is not as loud as my old craftsman washer. Highly recommended

The feature I like most is the quick-release handle; that makes it easy to transport to job sites without requiring any tools. For instance, I can wash my patio and then put into trunk and do my daughters patio without laying unit down or dis-assembly (requiring tools) of the carrying handle--simply snap it off and transport!

This was my first experience with Westinghouse outdoor equipment. So far, so good! I've had my WPX3400 gas pressure washer for just over a week and have used it two different times for a total of about 5 hours. I found the product easy to assemble and easy to start. It performed well cleaning my old vinyl siding and was easy to change the different nozzles. As mentioned in reviews I had read prior to my purchase, I did find spacing a bit tight during assembly and took precautions to avoid possible damage to my water hose.

I've used the pressure washer twice since purchase to clean my walkway and patio and it worked like a charm. My only complaint is the High Pressure Hose which has a tendency to kink up and get tangled. It's been my experience with other pressure washers that is a common problem.

The packaging during shipping was put together really well and all parts were there. We had owned an electric pressure washer for years but needed something more powerful to clean the Westinghouse 3400 got great reviews and seems to be easy to navigate. It’s lighter than other pressure washers, but still very durable

I bought this product at the end of April 2025. I have used it on a couple jobs that required me to run the machine for several hours at a time. It was efficient on fuel usage and provided ample power and in turn cleaning power. I was able to attach a 15" round surface cleaner tool and it performed as expected.

I bought this unit 3 weeks ago and have used it about 3.5 hours for various home cleaning products. I found the unit easy to assemble, easy to operate/clean, well-constructed and exactly what I needed around the house. Weight is reasonable as I sometimes load it in the back of my SUV for pressure washing projects at other locations. So far very pleased with my purchase.
