I spent a good amount of time doing research on gas powered pressure washers. The Westinghouse WPX3400 had everything I was looking for. The customer ratings were excellent. The warranty was the best. The pricing was fair. The choice was a no brainer. I had to have one.

I have a lot of trees on my property and my concrete porches and walkway get a black mold from the dampness and constant shade. This pressure washer along with the Westinghouse 15 in. Surface Cleaner Attachment cleaned up that concrete no time. I was pleasantly surprised.

My first time with a Westinghouse Pressure Washer. I had to print my own manual and quick start guide (carton contents shows inclusion with the product). Registration of the washer took too much time to locate the required information. Never did find a serial number.

I bought this machine in February 2025 followed directions and it started almost right away. I used it for about an hour and it worked real well in fact it surprised me when using the Westinghouse PWSC 15 inch surface cleaner it would actually lift in to the air if I let it. A couple days later I was continuing my pressure cleaning and it seemed to have lost pressure and would not lift anymore. The next time I use it I will check the hoses and filter for any blockages. If I still have a problem I will contact you and if it fixes the problem I will add that to the review and go to 5 stars.

We received our new XP3400 on Monday. Setup was very easy, only issue I had was that the Soap Hose was linked right where it goes into the Pump. I cut the hose just above the barb, removed the kinked part and reinserted the hose. An easy fix. Added oil and gas and it started up right away. Used it to clean up our mower, Perfect!

The design offers convenience and efficiency, compared to my old pressure washer. Assembling it was a piece of cake. It's easy to move from place to place because of the large back wheels. The User Manual is clear and exhaustive, and the explanation of the uses for the five nozzles is very helpful. I find it a bit hard to start, especially when the engine is hot.

I just bought the WPX3400. The price was very reasonable for a 3400psi gas pressure washer, and it gets pretty good reviews. Setup was super simple. The user guide is very nice. It walks you through all of the spray nozzles, and when to use each one. It has a nice maintenance guide, and user guide, that explains everything you need to do to use and maintain the machine. I have not used the pressure washer much, so we will see how it holds up over time.

i have used this power washer 4 times since purchase, and it has worked fantastic,easy to put together, easy to use,has more than enough power for any job,has great features,if you have light or heavy work to do this is the brand and product to get the job done right!

This is my 3rd power washer. The 2nd one was stolen and the first by this manufacturer. From what I learned my having the other power washers, this one had great features and I think will best support my needs. I am looking forward to using it very soon!

I had a 2550 PSI pressure washer (another brand) that was purchased in 2007 and I was looking for something with a little more power--that and I think the pump on the old unit might have been starting to fail. Regardless, the Westinghouse machine was easy to assemble and works well for what I will be using it for. I like that the unit comes with 4 spray nozzles--not counting the low pressure soap nozzle--which provides good options depending on what you're wanting to clean.
