Non stop perfection

We thought this was going to be for a small project. We ended up using ghisbfor about 5 hours a day for 5 days strait cleaning eavery piece of concrete we have plus a steel shop that has gone too many years without cleaning. There is not one thing I could criticize. We could not be happier

amazing machine

The pressure washer arrived well packed and undamaged. Assembly was pretty simple with just a few machine screws, nuts and washers to mount. It is built solid with quality features. Very easy to move around with the large wheels. Engine is built with quality materials and all controls are easy to reach.

WPX3400

Research this model extensively and found it to be second highest rated for its class. Instructions out the box are easy to read and the thing was easy to assemble. Everything needed is there in the box. Only thing I noticed was that they claimed you needed a 10mm wrench when it’s actually 13mm. Cycled the oil with a couple slow pulls of the crank and it wanted to fire right up without the choke. Ran smoothly and upon pulling the trigger of the wand you could immediately tell the power held there. I’ve used it for cleaning my concrete driveway (recommend the 15” attachment) made the cleaning fast and easy. Plenty power to remove mold and mildew baked on dirt etc. reasonably priced and well worth the money. The controls are plastic so due care with it will make the machine last.

Great but hose broke mid use on first time using

I purchased it last week. I used it yesterday to wash cars, and after using it for a bit, I noted a loss of pressure. I went to see what the issue was, and the hose was frayed. I was disappointed. Before that issue, though, the pressure washer worked great, and I was happy with it.

Great Features and Machine

The price of this machine was great. What sold me outside of the price was the features. I can use it without the assistance of my husband. It's easy to start and takes out the guesswork of which nozzles to use. It was a minor installation that was easy to put together. I highly recommend this pressure washer.

Replaced A Honda Powered Karcher with this unit

I've had this pressure washer for about 6 months now, and it has performed very well. It is much more powerful than the Karcher model I previously had, and it is a great homeowner pressure washer. I'm so glad I bought it. The only problem I've had is that it is difficult to start, but I'm replacing the spark plug with an NGK version, to solve that problem.

easy assembly and easy starting

This may be silly, but I was impressed most by the wand holder. All my previous pressure washers had a simple friction holder between the top of the handle and down by the wheel that never worked. This one has the same theory with a major improvement in design. By allowing there to be a catch for the water hook up on the handle so that it can not slide down and off the holders.

Unlimited Power

After wanting a pressure washer for years, Santa Claus finally delivered. I did plenty of research on various pressures needed as well as the debate of gas versus electric and admittedly I was a bit hesitant to go with the WPX3400, in the end I decided to pull the trigger and am so glad that I did. Set up was easy as the directions were clear and concise. Getting it running the first time was a bit of a nervous adventure but thankfully all went well. There were no leaks, no hiccups, the machine worked flawlessly.

Huge improvement

I have been using an electric pressure washer for a few years. It had a max of 1200 psi. I purchased the WPX3400 Westinghouse pressure washer 6 months ago and it has been one of the best purchases I have made. The pressure is enough to clean anything. Very happy with my purchase this far.

Great Pressure

Followed the set up directions that were very easy, filled oil and a couple of bolts that all. When I first started the power washer there was a high pitch sound coming from it. I was concerned that something was wrong however after running it for 10 minutes, the sound began to disappear. I am not sure what the problem may have been. The washer has good power and is easy to start.
