So far so good, very sturdy and works well.

I purchased this to replace an aging model from another brand. So far I've only used this new washer a couple of times, but I was very pleased with the performance so far. Assembly was easy and only took me about 10 minutes including opening the box and unpacking everything. The washer has nice sturdy wheels and rolls well, even over a gravel parking lot. So far, I'm very pleased. I hope it stands the test of time!

WPX3400

I've only had this for a week but seems like it's going to be a good pressure washer. Nice features compared to the one it replaced and it feels much stronger. I like the fairly compact design as well the layout of where the hoses attach so they stay away from the muffler. It starts first or second pull each time and is powerful!

Easy to set up, easy to operate

I bought this today, put it together, and started using it. The setup was fairly straightforward. The unit did a good job cleaning siding and concrete. I need to use it more to get comfortable with the different nozzles. The unit does better than my old electric power washer. So far I do like how it operates, although a little disappointed on how far the spray will reach. That thought might change as I use it more. I have a big deck and two houses I need to get cleaned so we will see how well it holds up.

Great quality at a great price!

Just purchased this pressure washer but the reviews were great and I'm looking forward to putting it to good use this spring. The price was great for what you are getting and I'm sure it will outperform any that I've had in the past. Here's to many years of keeping things clean!

Works great

Just got this pressure washer a couple of days ago after seeing it was a Consumer Reports top buy. I cleaned a bunch of sidewalks quickly. Worked great so far! Much better than my old pressure washer. The only issues were the assembly took a bit longer than expected.

Great quality tips, hose, and Instructions.

Received and started using today. I was using a Ryobi ez clean 18v power wash with 320psi and what a huge difference. I knew switching to a gas power washer was going to be a huge change but I didn't expect such great quality and craftsmanship from this beast of a power washer. I definitely will be upgrading to a 4gpm within the next couple months and sticking with Westinghouse!

So far so good

I have used the pressure washer once since buying it. So far I have no complaints. It was easy to put together and get running. So far the only complaint I have is the soap nozzle did not fit properly, so I accidentally shot it into the bushes never to be seen again 😂

Everything I wanted in a pressure washer!

After researching for a while I went with this pressure washer because of the good reviews (and was within my price range) and glad I did. Whether it's being used for our vehicles or washing our two story home, it gets the job done. Haven't tackled the driveway yet as I'm waiting on my surface cleaner to arrive but don't expect any problems with the power this thing has. Having the soap dispenser is a really nice perk as well!

Very happy with my purchase of this unit.

Quite impressed with the pressure washer. Great price for the power output and quality touches like large wheels and padded handle. Quick and easy to finish assembly after unboxing. Everything for use is included, including a bottle of engine oil and wrenches required to finish assembly which is basically installing the upper handlebars and the pieces needed to mount the hose and gun. I put it all together in about 1/2 an hour, filled the oil, added gas, hooked up the hoses and it started on the first pull which is quite impressive. Just bought it yesterday so have only used it about 45 minutes so far, but everything works well and I very much notice the difference between the power of this 3400 unit vs. the 2600 power washer I replaced with this purchase. Easy to start, clear engine controls, blasts away grime, does exactly what I needed it to do. Overall, consider it a great purchase. Why four stars instead of five? I knocked off one star for one detail. The only thing I find disappointing is the soap reservoir design. The cap and fill for the soap tank is blocked by the engine starting rope/recoil housing making it difficult to add soap. You'll have to use a funnel, or even better, a funnel with a flexible hose to fill the soap reservoir. In addition, since the reservoir is black plastic and the fill hole is blocked, you can't see when it is full when filling or how much is remaining when in use. Not the end of the world but if the designer had simply angled the fill spout down and forward a few degrees, it would have made the soap reservoir so much less frustrating, easier to fill, and use. If someone from Westinghouse sees this, please consider making the change to the fill spout design, your customers will appreciate it!

Leaking oil after original oil was put in…this power washer has never been started as a result of this leaking oil problem. Called your support line today to hopefully get this resolved without a lot of hassle. Usually by Honda motors…trying you out for the 1st time. Not good so far. Please resolve this issue…brand new power washer out of the box leaking oil is not good.
