  • Excellent build quality and extremely well thought out and written instructions.
Style: 3400 Max PSI
I'm impressed ! I've owned two Pressure Washers before, first an electric; that lost power as it aged over 2 years , then a Norther Tools gas that worked well, but build quality was not great. Sold both. This Westinghouse 3400 is by way and far the BEST power washer I've owned. As an engineer and most of my life in construction, I can safely attest to the great build quality, performance, great instructions , warranty. and Westinghouse brand, all add up to a great product that was affordable too. ... show more

  • Easy assembly and plenty of power for cleaning driveways and sidewalks
Style: 3400 Max PSI
Ordered the WPX340 as a replacement to my worn out old 2700 psi Craftsman gas pressure washer. Wow, what an improvement in power! Arrives mostly assembled in the box with easy to follow directions. Started right up and works great. I coupled it with the Westinghouse 15" surface cleaner for cleaning my drive and sidewalk, and it does a quick and thorough job of blasting off the dirt and stains. I use ethanol free fuel and SeaFoam fuel additive in all my lawn equipment and have had really good luck with extended life and easy startups. ... show more

  • Works Great - Read for a few recommendations
Style: 3200 Max PSI
Our old power washer gave out and we wanted a new one so I set out to research the best options. I quickly decided I didn't want an electric or battery power washer due to lower performance/power. I wanted one with PSI in the 2700-3400 range based on the jobs we would use it for (deck, fence, sidewalk, driveway, house and maybe cars). After researching it came down to a 2700psi or 3200psi Westinghouse or a Sampson power washer. Consumer Guides led me to the Sampson options as they raved about their quality, build level, durability and performance. The price was a little higher, but I wanted something I could rely on for years. However, as I read customer reviews I was surprised at how many 1 star reviews there was for the Sampson model I was considering. Plus, the bad reviews were almost all consistent with a terrible Kohler engine and a pump that fell apart too soon. I know all products will have 1 star reviews (this Westinghouse did as well), but 8% 1 star reviews on the Sampson with every complaint pointing to the same two key parts (engine and pump), plus horrible customer service reviews when people tried to get a brand new or nearly new unit repaired were just more than I was willing to deal with. So, I chose the Westinghouse since the 1 star reviews were only about 2% and the 4 and 5 star reviews were much higher. I did find that some people complained about the unit coming broken and not being able to return it to Amazon. However, Amazon was very clear that while you can't return the item you can get a refund or replacement if it comes broken. Some reviews had a broken/cracked gas tank or other shipping issues so I quickly decided that was not a worry for me and that I would pout it together and inspect it right away to make sure it didn't arrive broken or defective. It didn't and the assembly was quite easy with set up instructions and the parts each in their own bag that was labeled so you knew what bag/item to involve according to the instructions. Within 30 minutes I had the unit together and power washing. I will say that after reading the reviews I found some great tips that we decided to follow. First, we went to Ace Hardware and purchased a connector with a 60 degree angle so that the garden water hose that brought water into the unit didn't rub or rest against the wheel. I agree that this is a design flaw as the input valve is in the back of the unit just inside the back left tire and instead of pointing back away from the power washer it points directly towards the right side of the unit and the right tire. After reading a couple other reviews that suggested getting a connector with a 45-90 angle we purchased one with a 60 degree angle so that the hose then angled backwards away from the power washer and didn't rest or touch the right tire at all. Others had expressed that not doing this had led to their garden hose getting a hole worn in it by resting on the tire as the unit vibrated. The other suggestion that we did was to zip tie the power washer hose to the frame on the right handle right after where it attaches to the unit. Otherwise the hose comes out and runs right near the muffler that gets very hot. Customers had described how their hose touched the muffler and melted. A zip tie easily fixed this so that was not a concern at all and zip tying it didn't hinder the performance of the hose at all. We washed our large (20x12) Trex deck and 14 stairs leading from the deck to the yard, plus a rectangle table, 6 chairs, deck rail and our Traeger grill/cover all in about 30 minutes. Everything looked great and you could see the dirt easily wash off after a full fall and winter of not being cleaned. My wife even tested it on the side of the house and the concrete by the bottom of the stairs and it did great there, too. It's great that it comes with multiple easy exchange nozzles that also clip right into the power washer tray by the handle so they don't get lost. We've only used it once, but it worked great and was more powerful than our previous one. The 5 included nozzles will be able to handle every job we will want to do. So far we couldn't be happies and are glad we chose the Westinghouse model. ... 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

  • Great Pressure Washer

The WPX3400 is very easy to assemble. More compact than my old Craftsman pressure washer which is great for storage. The easy changing of nozzles is a plus as no tools are required. Owner's Manual is well written with clear instructions for operation and maintenance. It started up on first pull. Runs great and the pressure is perfect for cleaning my house and deck. Only the plastic wheels are a little cheesy. Otherwise, great product. ... show more
