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.

Extremely efficient Westinghouse gas pressure was

I recently purchased this power washer WPX3400 based on the Consumer Reports rating. The power washer definitely meets the high rating given by CR. The hook up of the pressure, water hoses and starting of the machine was very easy to do. The available pressure makes short work of deck cleaning and algae removal from my concrete sidewalks and driveway. I am very satisfied with this piece of equipment and am looking forward to using it to wash my house siding and on my automobile projects. Thanks for an efficient effective cleaning power house.

Workhorse - Definitely a must for those dirty jobs

This WPX 3400 pressure washer removed over 10 years of oxidation and stains on the driveway, sidewalk and patio. My overall first impression using this pressure washer is extremely positive. The concrete looks like it was just poured. I would definitely recommend Westinghouse pressure washers to family and friends.

Great features, easy assembly

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.

Washer so far

Just received and to cold out to use. My review will be for packaging and assembly. Very well packed. No flimsy box, substantial interior packing. Assembly was a snap, well thought out and clear. Exact amount of motor oil (which I recorded for future changes). Internal gas strainer. I'll give it 5 stars so far. I have a Westinghouse Generator that is outstanding, so I expect this pressure washer to be equally outstanding.

Nice Machine

I'm very happy with this pressure washer. It starts easily and has more power than I need most of the time. My only concern is that the washer hose is attached to the machine very close to the muffler and becomes very hot to the touch. I'm hoping that the hose doesn't rupture.

I just recently bought the power washer for an outdoor project. The pressure washer was easy to assemble the issues is the lack of water pressure. Checked to make sure that the nozzle and hose were connected properly. I also checked the water supply and for any debris in the nozzle and nothing.

Powerful

Just used my WPX3400 power washer and I'm seriously impressed. Tons of power—blasted years of grime off my driveway and siding with ease. It starts up reliably, runs strong, and the build quality feels solid. Definitely made a tough job quick and easy. Highly recommend!

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.

Was given this as a christmas present. I finally set it all up with some good spring weather and used it for a couple of hours and it worked well. Got 3/4 of my deck and trim boards done. Left it for 5 days and now it will not start. Pull string is also surprisingly hard to pull. Not sure if it came with a faulty spark plug or what, but It backfired after trying to start it for 20min. Kinda disappointing. I will continue to try to diagnose the issue or have it replaced.
