Unexplained shut downs

I bought this last week and I'm pleased with how easily it starts. It works really well with my 16" driveway attachment. The engine does seem to be overloaded when I use the 25 degree tip(the only one I've used so far). The one complaint I have is the engine seems to " flood out" for no reason. Oil level is good and I'm using fresh ethenol free gas. I suspect it has something to do with the vapor recovery system on the fuel tank but I'm not sure. Still investigating.

First use went great.

I have only used it once so far. It was easy to assemble and setup. It was easy to start and use, while it worked very well. After that first use, I have big expectations of further use, as I have many plans for pressuring washing areas that have been in need for some time.

Very cheap spray hose and parts do not fit

The soap nozzle doesn't fit on the spray gun. the first time I used the power washer, the spray hose briefly touch the exhaust shield putting a hole in it . No steel braiding on the hose nothing like that, just cheap plastic that quickly melts into a hole. Rather disappointed since all of this happened within the first hour of use.

Great gas pressure washer that doesn't disappoint

The WPX3400 gas pressure washer is an absolute workhorse and has exceeded my expectations in both power and reliability. With its 3400 PSI output, it easily blasts away stubborn dirt, mold, and grime from driveways, siding, and even heavily soiled decks. What really stands out is how consistent the pressure is—there's no noticeable drop-off even during longer cleaning sessions. The engine starts up reliably with just a couple of pulls, which is a huge plus compared to other gas washers I've used in the past. It feels well-built and sturdy, and the frame design makes it easy to move around despite its weight. The included nozzles give you plenty of flexibility for different tasks, from light cleaning to heavy-duty jobs. Another thing I appreciate is the onboard soap tank, which makes applying detergent quick and convenient without needing extra attachments. Maintenance has been straightforward so far, and everything feels accessible and user-friendly. Overall, the WPX3400 delivers excellent performance and durability for the price. It's a great choice for homeowners who want professional-level cleaning power without stepping into commercial-grade pricing.

First time using westinghouse outdoor equipment

Easy assembly. Easy connections and start. Slight burning smell for the first few minutes uses of use. Nice placement and ease if tip access. Hose is stiff. Havnt used long enough yet to give higher rating but will be using on several projects then will revisit for rating.

On the fence

I purchased my pressure washer 05/07/2026. Upon opening my package I heard a noise like broken glass or something. Once I got the unit out I realized it was the little beads from the moisture bag. I had to vaccum out the nooks and crannies of the unit and my garage floor. There is gas residue on the tank, might be from the testing phase. Some of the plastic was scratched. The front sticker is peeling off and it's dirty, making me wonder if I was sent a refurbished washer by mistake. I'm debating on trying it out or not.

Minor assembly notes

Easy assembly. Caution not to overfill oil—mine did not need entire 600 ml supplied (closer to 500 enough for dipstick to show as full). Hose from soap container arrived disconnected and manual not clear on proper connection (YouTube video helps). Caution: “Congratulations!/Register your product to qualify for a BONUS item!” offer shows wrong spray nozzle colors (Red and white reversed—red is the 0 degree). Color labels on machine are correct. Have not used yet as assembled on cold rainy day.

WPX3400 Pressure Washer

I have used it once. The pressure is great. The engine started on the first pull. The unit had a significant amount of oil covering it that I assume was left over from the testing prior to shipping. Additionally, the charcoal filter was not attached to the engine. It was easily attached after I found the placement on the bottom of the engine. It is definitely loud compared to my previous power washer with a Honda engine. If possible, I will leave a follow up review after a few years of residential use.

Very good pressure washer.

I have had this pressure washer for one week and have used it two days. I pressure washed a very large (16 x 50) back porch. That included the floor, railing, spindles and walls around the bottom. The washer has performed flawlessly with more than enough pressure and plenty of volume. It starts on the first pull every time. I am very happy with this product and glad I bought it.

So good so far.

So far so good. I just bought this power washer today. The assembly was straight forward and pretty easy. Once assembled, the unit started on on the 2nd or 3rd pull. I have only used 1 nozzle so far, but it did a nice job of cleaning up an oil spot on the driveway. We will see how durable it is over time. Only a couple of small issues that I noticed. 1. The instructions state that a spark plug plug wrench is included, but it was not in the box. This was not a big deal as it is not needed for assembly but would be nice to have for maintenance later. 2. The hose for the detergent dispenser was not attached to the pump and the instructions do not directly address installing it. That being said, the component picture identifies the Detergent hose barb so it was very easy to figure out.
