pressure washer WPX3400

i bought one last year, and it was a manufacture disaster. from the time i realized it wasnt working, it took 2 months going thru local repair shops, getting labels to return and getting replacement. it appears this one is working properly......we shall see.

Minor problems

I received this pressure washer on Saturday. Serviced it Monday and ran it for about 5 minutes. Released pressure and the engine started running rough and shut down. I drained the carb and checked the spark plug. Once that was completed, I restarted it and from that point on it ran like a kitten. I've used it for about 4 to 5 hours and it is still running great.

Rock crawler

Had to pull this uphill over large bolders to the job site without much trouble but watch out for the retaining pins on the inside of the wheel axle can easily come off. Luckily I had extra pins on hand. The mechine itself using the white nosel cleaned up the wood deck back to new like condition.

Started right up!

Ordered this model purely based on the high number of positive reviews, and the value for the pressure. Shipping was no issue, arrived within a few days as advertised, undamaged and with all components accounted for. Assembly was easy and instructions were clear. I did take the extra step to ensure that previously assembled connections were tight and there were a few that were a little loose, but mostly accessories, none that were critical to operation. Once fully assembled, oiled and gassed up I gave it a tug and it started right up!. A little louder than I expected but not excessive by any means. A great value for the price and hopefully it proves reliable as well. I plan to follow the maintenance instructions to the letter so hopefully it lasts a long time.

Great pressure washer

I just got the Westinghouse pressure washer to replace one that was lost in a fire. After putting in the oil and gas, it started on the second pull. It had never been run before and I thought that was amazing. I’ve been cleaning our driveway and it has great power to blast everything clean. Very impressed

First ever pressure washer!

It's really powerful for being a 3400. I have enjoyed experimenting with it. I have never owned a pressure washer before but I can say that I'm am not disappointed. If you're looking for something residential or commercial this pressure washer will do the job for any projects or ideas you have in mind of doing.

Westinghouse WPX3400

I brought the pressure washer and it was very easy to assemble, once assembled I oiled and gassed it up and it started on the 2-3 pull. I used it to clean dirty bricks and everything works fine. Just remember to cut the fuel off after using and to release the pressure after using.

Super Satisfied with the purchase

I bought this several months back but got to use it for the first time recently. It was a bit of struggle to first start the washer but when it did start it was pretty smooth. Couple of things I noticed is there are two oil openings which is confusing and also hard to access. I also wish there was separate soap dispenser switch so you can alternate between soap and just plain water, if there is one already I didn't find it. The pressure with which the water was dispensed was very good compared to my 1000PSI electric.

Great investment

After doing much research and reading reviews I decided to go with with the WPX3400 pressure washer and glad I did! Easy to set up and great options for pressure levels. I would recommend refilling the oil bottle that comes with unit because the opening is very small and this bottle fits it perfectly.

WPX3400 gas pressure washer

Just bought 1 day ago and put it together the next was very easy other than cleaning the oil off of everything. While cleaning I noticed that the pressure pump were not tightened down and oil was dripping from it. Tightened the 4 bolts and then added the oil then about a cup of fuel because was afraid the water pump could be bad. Luckily at this time no problems with the pump. I don't know if it is normal or not but it seems to walk aggressively with the pull of the trigger I may have to strap it down some how as I bought this for using on my dock and would hate for it to fall in the lake.
