Outstanding assembly features

Bought the washer 6 days ago and haven't had an opportunity to operate it. The assembly instructions were very easy to follow. Getting it into an operation mode was also easy. The unit came with the various assembly parts in designated bags plastic bags making it further easy for assembly.

Wide powerful spray pattern

After doing much research I just bought the WPX3400 power washer, brought it home put it together and gave it a test run. The Westinghouse power washer has great reviews, was easy to assemble and started on my first pull. It has a large gas tank which was lacking in previous power washers and the 15 degree spray head which, I will mostly use, had a wide powerful spray pattern that will probably cut my work time in half. So far so good.

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.

Good so far

Just received my WPX3400 Pressure Washer and tested it out. Did a quick once over of the patio and am extremely impressed with the power and how quickly it cuts through a years worth of grime. After using an electric pressure washer the previous years this is so much faster and does a more thorough job. The worst part of the experience was trying to read the tiny directions that are included. I'm not sure why they even bother and instead just include a link or QR code. It took longer trying to decipher them than to actually put it together. Once that part is done using the pressure washer has been great.

Average so far, but too soon to judge completely

Purchased a week ago and tested it yesterday on the driveway. The tool has decent power and works well for the price. I do have a couple of tough oil stains in the driveway that remain highly visible. I will give it another go after I purchase a better quality degreaser. The verdict is still out on this machine. However, so far, I am satisfied with the purchase.

Surface Cleaner is great!

Used it twice since I purchased it. Cleaned concrete patio and trex deck. The included surface cleaner and it worked really well! Cut the cleaning time down by at least 75%. Very happy with the product in the limited time that I have had it so far. However, I already burnt the outer plastic layer off the hose by letting it touch the exhaust manifold, so be careful of that. Wish that either the plastic was more temperature resistant or the exhaust was protected better.

What power!

I purchased this power washer a couple weeks ago and could not believe the power and how quiet the machine was. Things I cleaned in the past with my old power washer (different brand) took so much longer compared to my new Westinghouse power washer. Love It!!!

Good pressure washer so far.

Purchased 2 weeks ago and used it right away. Great power and everything works well. Nice to have the large fiel tank. Only compaint I have is that the engine was it bit hard to get started. It took several pulls (8-10) before the engine started and I was following instructions. My hope is that it gets easier as the engine gets broken in.

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.

Not the start I was hoping for.

Bought this pressure washer less than a week ago. The pressure hose burst the 2nd time I turned it on. Never happened before with my last one that I had for almost 10 years. Hoping Westinghouse sends me a replacement but definitely slowing down my pressure washing plans for now.
