  • A bargin-priced washer with big league performance - from a company I trust.
Style: 3400 Max PSI
Why did you pick this product vs others?: I was looking to replace a 17 year old craftsman that had recently developed issues. I decided to try the Westinghouse because I trust the company and the washer had many nice reviews. I selected the model (3400) with specifications (pressure and GPM) closest to the old washer. It arrived promptly and in great condition. No damage to the box or anything inside. The instructions are simple and clear and the assemble was easy. This washer is more upright than the old craftsman and therefore requires less space in the storage shed. I've had to air up the tires on the craftsman every time I've used it since new. I am thrilled with the tall solid wheels on this washer - no flats and it's easier to move around. I might add some washers to the wheel axles to take some of the wobble out. Not a big issue. I haven't gotten used to the position of the pull start yet. The craftsman seems better placed for propping your foot against it when you tug the cord. This one is probably perfect for a lefty. I'm still getting used to it. It starts easily and runs smoothly. The pressure is as good or better than the old craftsman with similar specs. This one does seem to be a bit louder, noticeable even with my hearing protection. Overall, I'm very pleased with my purchase. I've purchased the accessory 50' hose and am going to purchase the shorter snout for using my car foamer. I astounded at the value of this washer. Many comparable units I've considered are several times the price of this unit. Outstanding!!! ... show more

  • Perfect Pressure Washer for Any Scenario - Great Value
Style: 3400 Max PSI
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. ... show more

  • WPX3400 is impressive!
Style: 3400 Max PSI
I upgraded to the Westinghouse WPX3400 gas powered power washer from a Karcher electric unit. What a world of difference. The Westinghouse does everything I need it to do. It powers through the worst kinds of grime, mold, mildew, and dirt. I am very impressed on how simple it is to use and how easy it is to start up. It does not require multiple pools of the cord. Turn the engine on switch. Push the gas lever to on. Put the choke lever on and pull cord one time. Turn choke off and pull cord one more time and the engine is blazing away ready to do work. The wheels are big enough to make it easy enough to pull around in the weight is not so bad.I love this machine. ... show more

  • A Good Pressure Washer
Style: 3400 Max PSI
It is well made and works very well. The assembly was relatively easy. I recommend using the main book for assembly instructions as it provides more information on "How To” vs. the Quick Start sheet. The other caution I give is to tie the high pressure hose up along the right side frame rail so as to avoid contact with the muffler. This is perhaps something Westinghouse could improve in its design. The hose has labeled on it to keep it away from hot surfaces, but the design is such that the hose exits the water pump near the muffler. Other than this slight issue the pressure washer works great. ... show more

  • Reliable and Efficient Pressure Washer by Westinghouse
Style: 3400 Max PSI
This pressure washer by Westinghouse stands out as a sturdy and efficient machine that effectively gets the job done. Assembling it is a breeze, especially with the detailed main instruction book that provides more comprehensive guidance compared to the Quick Start sheet. One helpful tip is to secure the high-pressure hose along the right side frame rail to prevent any contact with the muffler, highlighring a design aspect that could be improved by Westinghouse. While the hose is labeled to avoid hot surfaces, its proximity to the muffler could be better planned out. Despite this minor flaw, the pressure washer excels in performance, proving to be a reliable choice for various cleaning tasks. ... show more
