The WestingPower WPX3400 is a beast. It blasted years of grime off my driveway in minutes and made the siding look brand‑new. Easy setup, strong pressure, and solid build. I ended up cleaning stuff I didn’t even plan to because it was that satisfying. Great power washer.

Purchased in August '25. Used 2 times and it worked well. Stored for winter after using pump protection sealant, as directed. Stored inside in heated environment. March '26 started up, it works but very low pressure. this thing is new; it was stored as instructed and still does not work right. Really? Now what?

I have not actually used the product, so this review is based on first impressions. Setup/assembly was easy, though I wish there was an oil fill indicator rather than having to fill a little at a time and check with the dipstick, which makes it easy to over fill the oil. The price was right for the features, though the unit feels a little light duty and not as heavy or sturdy as I was expecting. Online reviews are generally good, so hopefully this won't be an issue.

Great pressure washer for the price. It has done an excellent job on everything I put in front of it. Keep an eye on the oil level it’s very easy to overfill the oil. It’s tricky to start when it’s hot, I have to crank it at half choke when the engine is hot.

Bought this to clean vinyl siding, concrete driveways and walkways,and off-road vehicles. It has already paid for itself compared to hiring a company to do this. The pressure washer was delivered damage-free and was it was very easy to assemble - just put on the gun holders and mounting foot and the hose. It even includes the needed tools.

Just got it home and unboxed. Love the quality of the build and there are some extra touches that I like. There's a choke, fuel shut off, and everything is easy to get to. Plus it feels sturdier than my last pressure washer. I think I'll like this one

Runs good does a great job hard to start the first time because I didn’t make sure all the switches were set in the right place after getting all that right pulled twice started right up and did the job bought to clean sideXside.And also easy to put together

Haven't fired it up yet (waiting on adapter fitting) so can't yet give five stars. However, I've noted multiple design features that I like. Unit is compact (front to back) making storage easy. Controls are large and clear, and the storage for spray nozzles is very nice. Impressed that the gas cap was attached to tank by a metal chain, and not some flimsy plastic (or with nothing). Access to hose connection is clear, which wasn't the case on my previous pressure washer. Made purchase because this was rated at the top choice by Consumer Reports.

took only 15 minutes to take out of the box, put it all together & have it hooded up & running. started right up & ran great. registered only 3000 psi on my gauge but that was expected cause no pressure washer made gets what they list at max psi. But still has plenty enough power to do the tough dirty & greasy jobs on concrete. Very happy with purchase so far. i do suggest getting a lot better hose that is kink resistant & short nozzle spray gun which makes it a lot easier to use

I purchased this WPX3400 gas pressure washer April 8th, 2026, first because I previously purchased a Westinghouse Dual Fuel 7500 Generator that is the real deal as Westinghouse makes an outstanding product. The workmanship is first class, easy read directions and everything fit to perfection. I can’t wait to use the pressure washer and am sure it will do great work. I believe you can’t go wrong with this purchase.
