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.

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.

Reviewed several pressure washers in this range, and even an AI query agreed that this unit was the best value and performance option. Just took a few minutes to put together, fill it up with oil and gas, and away to the races! Started right up, no issues, and it cleans much better than the one I just retired. I especially liked the on-board soap tank, which made it easier than my old solution. Remember, you can be sure if its Westinghouse :) .

At the beginning of 2023 I decided I wanted to buy a pressure washer. I have never owned one or been in possession of one, so I was completely new to this. I bought the WPX3400. The engine is pretty straightforward. There's a dedicated off switch, a choke/run toggle, and fuel off/on switch. On either side of the base of the engine where the block meets the wheel axle/frame are oil intakes. One is a bit more accessible than the other. The engine itself runs well. The pull start is smooth: if you haven't run it in a bit, it'll usually start within 4 pulls assuming everything is set correctly. If you have to shut it off midway and restart, it almost always starts on the first pull. I make an effort to keep it as clean as I can, and always out of the way of the sprayer. A full tank will take you pretty far in this as well. Just regular 87 gas. I did my whole concrete driveway and patio which hadn't been cleaned since it was poured. The difference is significant. I also did the concrete patio and some stone blocks at my other house, and also used it to quickly and effectively jet out the septic system of this houze with an aftermarket set of nozzles and hose. Again, worked wonders. The provided nozzles cover a good range of uses, from car cleaning to wood, vinyl siding, all the way up to very strong and narrow beams, which I don't really know what you would be spraying with that wouldn't be destroyed or seriously damaged. The broader nozzles do great for concrete and vinyl and softer targets. I have noticed that my hand will cramp after prolonged use of the sprayer gun. I always wear gloves but sometimes it can be taxing on the hand since it does shake and recoil a bit. I've had two instances where I've had to troubleshoot the machine. First, I suspect it may have run out of oil. It was running normally then just kinda sputtered out. I checked the oil, but I thought it was fine based on the indicator stick. Still, I topped it off, and it came back on with no issues. I'm not sure if the oil was the solution there. Another time, I noticed that the washer wasn't getting a consistent output flow of water. I had two garden hoses daisy chained together with an adapter between the two. One hose had a rigid body, and the other hose was one of the expanding/contracting hoses. After troubleshooting for a bit, I found that the fact that these hoses were connected and leading into the washer caused some sort of problem with the water flow. After setting it up so that there was only one hose leading into the machine, the problem seemed to have resolved itself. I found it odd that for all of the times I used this washer before in tandem with the shrinking/expanding hose, I never had any issues. I am still scratching my head over that. I also bought a set of extending poles for the washer, however I was not able to use them to their full potential because I could not connect them to the gun. The gun has an M22-14mm swivel port where the wand attaches. Keep this in mind if you have any accessories you plan on using with this, or consider an aftermarket sprayer gun, which might offer a more ergonomic handhold. To summarize, this thing is a champ. It's run reliably since I started using it in February when I first got it. I was jumping out and doing some practice runs in between bouts of non-freezing weather to dial it in. I used it last week to un-cake the pollen and sap on my car, which also did an excellent job. If the idea of buying one has been on your mind, this is a fantastic and well rounded option. It's decently powerful in terms of the PSI/GPM ratio, which I considered one of the more important traits of a pressure washer. Gas engines just run better compared to the inconsistency from electrical/battery variants. You're going to find yourself wanting to use this very frequently.

Great little beastie. One of the best in this price range with a high GPM compared to other machines. Bought as a replacement for my old Yamaha when it had a major medical event. Excellent power with multiple tips and a soap reservoir which is very handy. Assembly is pretty easy and they even provide a forged wrench instead of those awful stamped steel versions. The wrench was good enough to earn a place in my tool cabinet. I do suggest having a small rachet and a 10 mm socket on hand for a couple of difficult fittings. Starts easily and has a good size gas tank, so you can keep right on working. Rolls easily and has places to store your wand and pressure hose. A very good value, but pay attention to the maintenance schedule. It's not hard.
