I bought this pressure last week on July 9, 2025. Assembly took about 30 minutes. No problem with packaging. Love that every part bag is labeled with part names. Wish every company did that. Easy to read manual and the quick start guide is very helpfull. I installed quick connect couplers to make attaching and detaching high pressure and water hose quicker. The oil filler attachment definitely came in handy. After adding oil and gas started on second pull. Ran it for 30 minutes to test washer out on my patio. As you can see I from the photo it did a great job washing away dirt by the water drain. Definitely a powerful pressure washer. Initially I am giving 4 stars because the unit walks to much when running. But this is because of the power it’s generating. I am going to purchase wheel blocks to prevent the unit from walking too much. I may change rating to 5 starts after cleaning driveway and second story siding.

Got the 3400 psi for Father's Day and was eager to get it together! Right out of the box, it's easy to put in to use! Simple instructions...about 20 minutes and I was pressure washing the front porch! Impressive power from the small engine. Fairly quiet to run and the nozzle makes it easy to use! Over all, a 10 out of 10 thus far! Can't wait to get it on the back deck!!

This is probably my 3rd or 4th pressure washer in the last 25 years, and now I see what I was missing before! This is the largest PSI washer that I've ever owned, and I was afraid it would be very loud, but it is much quieter than I thought it would be - quieter than my Craftsman that decided to "die" on me a couple of weeks ago (and I had only had it for about 4 years!). Easy to assemble, easy to operate, no "kickback" like I had expected. I've only used this washer a couple of times, and I excited about using it for many years to come.

Absolutely wonderful machine!!! Thorough and comprehensive instructions, works and runs tightly, starts easily and consistently, oil charts and maintenance recommendations that are very helpful. Pre greased inlets are much appreciated. Would recommend 5/5!

Overall the performance of the machine is great easy to use and maneuver around power is more than enough for concrete. Future tip for engineer's, currently the only way to change the oil with this model is to pour it directly on the platform which the engine is on leaving a mess, a pre-milled hole on the platform to allow the oil to flow out in to your oil pan instead.

Our family watched a program, American Built, on the Fox Nation channel that explored the history of Westinghouse. We were thoroughly impressed by the dedication of the work-force that made the company grow, especially the reliability built into every product. We were in the market for a new pressure washer, having given our younger son our old unit, and after some research, decided that the Westinghouse WPX3400 would be exactly what we wanted. After purchasing the unit, we discovered that it came with only a few parts that needed to be attached (with exceptional instructions) and it was a well-built, compact unit that could be easily stored when not in use. The pressure washer is better than anything we have ever owned and I use it often, given the Florida climate conditions, where mold grows on on patio blocks, concrete surfaces and pool enclosures. We are very pleased with the WPX3400 and have actually recommended it to several friends. Thank you Westinghouse!

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.

I bought this power washer in April 2024. It was easy to set up and use. I have used it already on my house siding, cars, as well as on my driveway (using the round attachment). My driveway and sidewalk looked brand new once I finished. I would highly recommend this power washer.

Washer is very well designed with hose connections, fluid ports, and nozzles in easy-to-reach locations. The product was lighter than I thought and can be lifted into truck by one person. The large wheels make moving the machine much easier than previous models I have owned.

After using an electric pressure washer off and on for a few years, I finally made the swap to gas power and don't regret it. This started on the first pull and performed perfectly. As with all power washers, I would recommend making sure the water is cleared from the pump after using it but otherwise, you should be golden.
