  • Perfect Pressure Washer for Any Scenario - Great Value
Style: 3400 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

  • Good PSI for what I need it for
Style: 3400 PSI
Good choice for residential use at $349. Easy to assemble and already has a pretty good set up for basic cleaning, nozzles and soap tank. 3400 is plenty strong to do driveway, house wash and cars. Oil was included with a convenient attachment for easy pouring. I'll probably hang on to that attachment for future use. I looked at more expensive models with Honda motor, but decided to go with this pressure washer, because the features and PSI was the same, but the price was a lot better. If you need a good pressure washer for various cleaning jobs- this is a good purchase. ... show more

  • Great power washer with one unfortunate flaw
Style: 3400 PSI
The Good: Quality is overall great. Good fit and finish well packaged and easy assembly. Blows my father in law's ryobi out of the water. It's powerful and easy to use. The biggest difference is noticed by far was the included house and gun were on a whole other level quality wise compared to the ryobi i had been using and some other cheaper units i compared. Really didn't need any upgrades but I did get the McKillans quick connect kit and pro short gun as well as an extra pliable hose. The short gun and hose were mostly for more flexibility when washing cars there's absolutely nothing wrong with the included equipment. The Bad: I wish it was perfect and it came close, however they have pretty bad design flaw. I ended up damaging 2 of my expensive real rubber water hoses before figuring out what's going on. The problem is that the inlet port for the hose is directly out the side and tight in so it's impossible you keep the hose from touching the wheel and upright support. Because this is a gasoline unit it does vibrate quite a bit and caused the hose to chafe and eat through. Once I caught on i repaired my hoses with some flex tape and bought an L elbow that took care of the problem so the hose connects directly from the rear and does not contact any other piece of the unit. ... show more

  • Very good pressure washer
Style: 3400 PSI
Easy to assemble. Very detailed instructions. Pressure washer works outstanding. The 3400 psi is fantastic. Remember to never let the pump run without the sprayer wand being used for more than a minute. Otherwise it will overheat the pump and damage it. Great purchase at a great price.

  • Very happy with this pressure washer.
Style: 3400 PSI
Works great and very powerful compared to my last pressure washer. I trust the brand and recommend to anyone looking for a pressure washer. Also bought the Westinghouse surface cleaner that makes easy work of cleaning a driveway and sidewalk. I also recommend using gas with no ethanol in it even though gas with 10% or less will work too, better safe than sorry. It comes with 5 different nozzles for cleaning and a 25ft hose even though I went ahead and bought the Westinghouse 50ft house. Also got the Westinghouse 6 in 1 nozzle, comes in handy. ... show more
