Review: Perfect Pressure Washer for Any Scenario - Great Value - I bought this pressure washer after considering a plethora of different makes and models, including the option of electric vs. gas powered. I am glad I chose gas, and I'm glad I chose this Westinghouse WPX3400. I chose gas because it is much more powerful than electric, and I chose Westinghouse because they have a decent reputation, and the WPX3400 because that was the best "Max Pressure to Cost" ratio. I have used at least a half-dozen different pressure washers, mostly gas-powered, but never owned my own. Now that I have a property that I need to maintain myself, I believe it was WELL WORTH the price of this machine to be able to take on the significant number of tasks and projects that would require a Pressure Washer. The assembly was simple. Just a couple nuts and bolts to screw in (clearly labeled in the manual with pictures), and the top handle just slides on - no tools or bolts required. Great design. Starting Up: I thought that this Pressure Washer was a little flaky on the VERY FIRST USE. It took several pulls to start, and it stalled out on me. However, EVERY USE after the first, it has started up on the FIRST PULL! Seriously. If you buy this, expect your first startup to be a little rocky, but just let it do its thing - it'll either stall or you'll power it down... After the first use, expect every single use to start on the first pull, every time. That's how good I feel about this machine, after a small sample size of uses (~20 times). CAVEAT: If you are going to own and care for a Pressure Washer, you need to understand how to do things the right way. What I wrote above, about this machine starting up smooth every single time (from the second use on), will only be true if you care for the machine correctly. First, get yourself some 4-stroke engine oil as well as some "pump protector". Both of these items should be in the single-digit dollar amount. You will want these on hand because at some point you will need to: 1. Add more oil (or change the oil), and 2. Clean it thoroughly and protect the engine if storing it for any length of time. Second, read the manual in entirety, it's not long. If you're one of those people who throws away the manual without glancing at it and says "I got this", nobody thinks you're cool, and you might miss a potential quirk unique to a machine that will ruin your investment if you don't know about it. I won't summarize the manual here but I will touch upon two key things you need to be sure of before buying/using a gas powered machine like this WPX3400. - Be liberal with the "sample oil" included inside the box. I'd say use about 3/4 of the entire bottle, if not more. Use the dipstick to check the fill reading, and keep adding a few pours until it's at the right fill. - Connect your garden hose to the outdoor spigot and run the water for a few minutes before connecting it to the WPX3400. You want the hose full of water and not have any air pockets spurting out. Once the flowing end of the hose is pouring solidly, turn the spigot back off. - With the spigot turned off, connect the other end of the hose to the WPX3400. Go back and turn the spigot back on. With water now flowing directly to the machine, follow the startup procedure written in the manual, the basics being: Turn Power On; Turn Fuel Valve to On Position; Make sure engine is in "Choke" position; and give the ripcord a solid tug. If it doesn't start by the fourth or fifth pull, turn the water off and reassess. A few other helpful tips: - Once you get the machine running for the first time, don't worry about a stall or some slight oil burn. You want that first use to be continuous water spraying for several minutes. - On each successive Power Washing Session - you ALWAYS want to have the water spraying out of the nozzle at all times. If you need to let go of the nozzle trigger for any reason, try to get your finger back on that trigger as soon as you can. Ideally, you want to be continuously spraying water from the nozzle the entire time you are washing. Yes, this might seem like a waste of fresh water, but this is how you care for your investment. Instead of letting go of the trigger, move the nozzle away from your target and spray at the ground or into the air, and keep doing so until you are ready to spray your target area again. - If you know that you'll need to stop spraying for longer than 20-30 seconds, STOP what you are doing and TURN THE ENGINE OFF. - That might sound a little crazy, but this will preserve the engine life and performance. - Don't ever leave the engine running without spraying through a pressurized nozzle for more than 30 seconds. - If you need to stop your work for longer than that, turn off the engine; move the fuel switch to off and the engine switch back to "choke", then turn the water off at the Spigot. Disconnect the hose from the WPX3400, then pull the trigger on the nozzle to release any remaining pressure. - Do not attempt to change the spray nozzle until you have released all pressure.
Review: Excellent Quality - It is very simple to put together to start it! The manuals and parts list are all extremely helpful, far more than most product manuals nowadays. It is very powerful and durable!

## Questions & Answers

**Q: When swiching frm soap mode to rinse mode how do you shut off the soap?  Do you disconnect the soap hose?**
A: The black nozzle is the soap nozzle When it is attached the soap is dispensed from the onboard soap container.
If you want to dispense from a larger container. You will have to detach the hose from the bottom of the onboard container and add an extension hose to it. Local auto parts stores carry the tubing(hose). Then you can insert into any size container you want.
As far as the gasoline. The engine is designed to use 10% ethanol. You can use non ethanol if you want to. Do not use anything over 10%. Especially E85.  E85 will burn up the engine.

**Q: Hot water capable ?**
A: Never use hot water with a regular pressure washer.  There are add-ons that will heat the water AFTER it's pressurized by the washer.

**Q: Mine will not start. Started right up the first time. 3 days later won’t start. Manual says prime it, there is no prime bulb?**
A: I had that same problem. Connect the hose with a shut off Connected, prime the pump, then turn off the water. The washer will start,  then quickly turn the water back on. Works every time

**Q: Is this pressure washer made in America? If not where**
A: Simpson and Generac are made in America

### ⭐⭐⭐⭐⭐ Excellent Quality

### ⭐⭐⭐⭐⭐ Great pressure washer for a great price!
*by S***H on December 6, 2025*

Great pressure washer. Pressure is excellent and engine starts right up with no problem. This thing works exactly as it should, the only problem I've noticed is if you accidentally fill up the gas tank too much and screw the cap back on, it will stall. The fix is to keep the cap off until it's used up a bit, or pour some out. Just don't fill up to the top haha.
