Easy setup except for the bolt supplied to attach the lower holder. Nut was stripped and I couldn't get it on the bolt. It is metric. Who has a metric nut and bolt. So had to dig into my stash and get a SS bolt/nut I had to finish the job. Seems to run good so far. Too early to tell.

No major issues. Assembly was easy and instructions were fairly straightforward. (The push rivet on the upper gun holder could use some additional clarifying information.) It started on the second pull. After a couple of hours of use it was working fine.

Purchased this 3400 PSI gs pressure washer in June 2025. Used to power wash my 100+ year old barn tin roof. Started right up no problem. Great performance - had 150' water hose attached from farm well. Did great with water quantity and pressure force. Used 25 degree nozzle. One thing I noticed was when moving the machine around on it wheels and thereby tipping the engine at an angle that the engine would not re-start very easily. It must "flood" really easy as I think that was the problem. Sitting still - no problem - starts right up. Trying to start after moving - it was a pain in the arm to get started. Only time I used thus far (1/2 farm day) but will observe on my next usage that will occur soon.

I did a lot of research on gas powered pressure washers before deciding on the WPX 3400. Just assembled it and did a quick test and it performed as expected. Assembly is easy and only need to install the handle, hose and wand, and add engine oil.For the price it appears to be reasonably well made. Lots of plastic but competitors units at similar price point also have plastic parts. I hope that with proper care and relatively infrequent use I can get it to last for at least 300 engine run hours.

We had a sears craftsman 2000psi it is about 25 years old. So I did my research and decided to take a chance on the Westinghouse 3400. So far it is a step above my old one. I hope that the longevity is equal. If you are looking for a new pressure washer I would definitely give the Westinghouse a chance. 🤗

This thing is a beast! The pressure it generates is beyond my belief. The only downside to me is the fact that it's very noisy. I love how the hoses hook up, the never flat tires and the wand holder. Not to mention the three-year warranty. I am so glad that I researched washers before I made this purchase. Kudos to Westinghouse

Just bought this a little over a week ago. I've already washed the siding on my house (it even took care of the green stuff on the north side), the porch, and the carport. Then loaded it up and took it to my folks. No more worry about them slipping on mossy deck steps! Very pleased!

This unit was easy to assemble, had no missing parts, and started right up. It had very good pressure and worked as advertised. I only gave 4 stars because the soap hose got kinked in the packaging process and the kinks will not come out. This has been mentioned in other reviews but has not been addressed by the manufacturer.

Purchased 3 days ago. The WPX3400 performs well with enough power to strip a deck for restraining. Initially easy to assemble the power washer and unit has thirough owners manual.. The power washer was easy to transport and lightweight. The unit performed well for deck stripping with plenty of power.. only problem I experienced was that the power washer struggled to restart after the unit required refueling. The starter pull rope combined with how light the power washer was made it difficult to pull the rope to restart the unit (rope hard to pull with resistance from the unit). After three or four pulls, the unit restarted and performed well.

I had another PW that did not have the power that this has. I shopped around and decided to purchase this. Boy am I glad I did! This PW packs a punch. I started with my brick porch and concrete sidewalk. Very easy and did not use any cleaners. Worked like a champ! Also did the front of my vinyl siding house. Took the dirt and mildew off very easy. I will post before and after pics shortly! Take my word, you will not be disappointed with this! The setup was very easy too. I am pushing 60 and put it together myself. I would recommend this any day!!!
