I tried this today after buying it a few days ago and I am very pleased with the effectiveness of the sprayer. However, if you're doing a two-story home, you will need to purchase the two-story sprayer nozzles. The unit is very user friendly which is also a bonus!

I bought this Westinghouse WPX3400 in April of 2023 and couldn’t be happier with the power and quality of this pressure washer! This has been bulletproof and starts on the first pull every time. I’ve used this to clean my 1300 sq ft patio multiple times running it for 8+ hours at a time with no issues! Would definitely buy again!

The assembly and startup were straight forward and relatively easy per the instructions. The washer works good for cleaning cement and is easy to move around. I purchased it to help clean my deck, siding, cement driveways and patio and sidewalks. It has plenty of power. I only wish there was a feature to select a lower pressure at times but I knew it didn't have that option before I bought it (that's the only reason I rated it 4 stars instead of 5).

I am new to owning a pressure washer, and this was an easy assembly. For a female, it started easily and was simple to manage... until it started smoking. After investigating the problem, there was no air filter! Now I have spent half a day trying to decide how to go about getting one. Help, Westinghouse?

My pressure washer was just delivered and the box was damaged. The soap inlet hose was bent to the point where fluid was not going to be able to pass through it. I cut about an inch off the tube and reconnected it and it should work fine. The power washer was easy to put together and looks sturdy.

They don’t say you need a hex key in the setup manual which may be problematic for some people but that was the only critique I had while setting up. The oil jug and the narrow nozzle was very nice to use. Haven’t fired it up yet but I’m happy with how it’s looking.

I’m very impressed with this pressure washer! The Westinghouse 3400 has plenty of power and makes cleaning quick and easy. It starts up smoothly, runs great, and has handled everything I’ve needed—from the driveway and patio to outdoor furniture—with no problem. Solid build, easy to use, and excellent performance. Highly recommend!

Just bought this gas power washer and it was simple to assemble. Started right up on first pull. Plenty of power to do sidewalks and driveway. Very pleased with the purchase and would recommend to anyone looking for a gas power washer for their home jobs.

i have used this power washer 4 times since purchase, and it has worked fantastic,easy to put together, easy to use,has more than enough power for any job,has great features,if you have light or heavy work to do this is the brand and product to get the job done right!

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.
