Gas power washer 3400

I bought this pressure washer a couple weeks ago after having a Ryobi electric power washer for about 7 years. I assumed it would be better, but it still exceeded expectations! It has enough power that it makes you cautious how you use it (so you don’t damage things) I have only used it twice, but as for performance I couldn’t ask for more… it’s more power washer than I needed, but I’ll take it! It has the pressure to mess things up if you’re not careful, and the volume (GPM) to push water well for thoroughly rinsing anything you clean. After having an electric washer for 7 years I can tell you psi often isn't the most important thing. The electric washer had enough psi, but it didn’t push have the water volume to really push the dirty water away after the pressure knocked things loose. Very good washer I highly recommend!

Missing air filter!

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?

Easy to assemble, easy to use.

Best/highest rated residential pressure washer on the market at a great price. It was extremely easy to set up and similarly easy to use. Would highly recommend for other home users. So far I’ve used it on my wooden deck and my concrete driveway with great results.

Best gas power washer in its class

I received this as a gift. It is much better than I thought it would be. Ease of assembly was great it only took 20 min. After adding the oil they provide and some gas it was ready. Two pulls later and it was off and running. The pressure was great and consistent.

My Landscaper recommended this one...

My landscaper recommended this one and he was right! Easy to unbox and assemble. Started on second pull and has plenty of power to get to my two story house and pole barn. Worked great on the mildew on decks and siding. Bought a 40' extension hose and worked better in my case.

I like the thought that was designed into it !

When adding the oil for the first time, one has to notice the thought that went into the building of this machine. It was designed for easy oil changing. There is a cut out in order for the oil to drain into your pan nicely without getting all over everything . One has to like the set up of the gas tank. The fuel tank has a chain Attached to the lid so you don’t lose the lid. Also, the tank has a built-in filter for the gas, which is easy to take out and clean. The spark plug wire was designed for easy removal. It has a hard plastic coating at the top for easy removal . This sprayer is set up for easy maintenance for the person who likes to keep things around for a while. Way to go DESIGNER team ! Last but not least the price was very reasonable !

Fantastic Piece of Machinery

I bought this to pressure wash a vinyl sided house that I've been hired to paint. Initially, I bought an electric and while it worked very well, the cords made it less portable than this. The gas powered WPX3400 arrived mostly assembled, is powerful and made washing a breeze. The homeowner is not only happy but extremely impressed with how thoroughly this machine cleaned her home, and so am I.

Great features and happy with results!!!

This pressure washer has been a game-changer for my outdoor cleaning projects. After years of struggling with a less powerful model, the [Brand and Model Name] has proven its worth on everything from grimy siding to stubborn deck stains. It's an excellent balance of power, portability, and convenience that makes tough jobs surprisingly manageable.

So far so good.

I just hit the five hour mark so it's time to swap out the oil that came with the machine but so far I like it better than what I had previously, name a gas powered and an electric powered pressure washer. Noticeably more powerful than the other gas powered model, and of course the electric doesn't stand a chance. The large wheels are awesome as I've already wheeled it over things that my old model would have never been able to handle, plus the old model had the connections on the underside of the frame which naturally had way more cons than pros. Know that if you attempt to use it just about any aftermarket high pressure hose that has a plastic grip "handle" on it then that will likely push up against the frame to an uncomfortable degree. Finding a 90 degree adapter for the garden hose is easy as it's similar, but finding a sweeping M22-14mm adapter is tough if not impossible (and not cheap) so the best thing to do is use the hose that came with the unit as a leader hose. Even if that hose fails on you at some point, short replacements are available that will serve the same purpose. Formally, Westinghouse's position is that: "We can only recommend using the hoses that come with the unit, as they are specifically designed and tested to ensure proper function and performance. Any information regarding the use or setup of non-OEM hoses would need to be sourced independently, as we’re unable to provide support for third-party components." Hope this helps, have fun and be safe!

Great and affordable gas pressure washer

It comes in a very secure box. Assembly was simple and only took about 20 minutes from opening the box until starting it up. It does a great job cleaning. It's simple to use and easily maneuverable. The pressure washer is going to save me a lot of money over the years. I HIGHLY recommend it.
