Great Purchase

I just purchased the Westinghouse Power pressure washer and I used it for the first time this weekend to wash the car and it worked better than I expected. I loved the soap dispenser it made washing the car so easy.

Power Washer Great-be careful of Allstate Warranty

If you add the Allstate 4 year warranty, be careful.... Allstate counts the manufactures warranty (1 year) as part of the 4 years... Kind of shady on their part. I ended up canceling the warranty.

Performs Well!

Only one wash in and performing as expected so far. Doing the review for the free additional nozzle tips, otherwise I would wait longer to give my experience. Several years ago someone had given me an electric pressure washer for free. It's 2,000 PSI and 1.1 GPM, basically worthless garbage. I previously worked a job where we had a commercial grade 4200 PSI 4.5 gallon per minute machine that had spoiled me to how well a pressure washer can work. Doing my patio I finally got sick of the one I got for free, did some research, and went and picked this up. Night and day difference between this and that electric 1.1 gpm trash. I should've done this years ago. It's obviously not as good as the commercial unit but I am happy with the performance. It was packaged well, easy to put together, and seems solidly built. I cannot speak on the durability having only used it once.

Excellent Pressure Washer

I just purchased this pressure washer a week ago. It was just minor assembly and had it up and running in about 15 minutes. I tested it on my concrete driveway that had 20 years of black crud on it. With the 25 degree nozzle it cleaned to the bare concrete with minimal effort. I'm very happy with this purchase.

Powerful and Easy to Use

Very happy with the Westinghouse WPX3400. It has plenty of power and was straightforward to assemble and get running. The different quick-connect nozzle tips make it easy to switch between jobs, and the soap tank is convenient for washing vehicles and other larger projects. The unit feels solid and well built, starts easily, and the wheels make it easy to move around. The 3400 PSI provides more than enough cleaning power for driveways, sidewalks, decks, siding, and vehicles. Overall, it’s a great combination of power, features, and value. I would definitely recommend it.

Do Not Overlook This Brand

I recently ordered this model to replace a Ryobi electric washer. The Ryobi was/is working fine but just has a bit less power than I require for the driveway. First off.......I am not in the business of pressure cleaning. Just a regular homeowner like most people out there. So I can only go by my personal product experience. My other Westinghouse outdoor appliance is the WGen 9500 12500 dual fuel generator which I have enjoyed a trouble free 4 years of use. Even the electric start battery is still going strong. Unlike a Generac we owned which cracked the first time we really needed it and cost 5 times as much. So, going by the quality of the Westinghouse generator, I decided to try the pressure washer. The machine was well packed. The instruction booklets are excellent. You are provided with everything you need to put it all together. Minus fuel of course. There was a little oil in the box which tells me that the unit actually was tested. I have not done any serious washing yet but after setup, turning on the water, bleeding air from the hose, the unit started up very easily. And I could see the difference in pressure compared to the electric Ryobi. With regular yearly oil changes, and using rec fuel which is all I use for my gas powered outdoor tools and boat, I expect this washer to last just as my generator has done. For the average homeowner this should be all you need.

Will have to determine reliability with time.

I followed the manual setup instructions carefully, but the WPX3400 pressure washer did not start easily. When I moved the choke from on to run, it started up.

Good unit so far

So far so good - but it took TEN pulls for my initial start-up!! Otherwise ran well and performed as expected. Will wait to see how it starts up next time I use it. Wheels are of cheap plastic - expected better. Great power - clears exactly as it should.

Great out of the box, not so much shortly after

It's an average pressure washer at first. I tried to stay within guidelines for oil changes as recommended. I am now experiencing some issues with the washer. I have a gas leak at the carburetor gasket and cup. It also shudders where i get hose vibration reduction of pressure and sounds like it may stall out. This happened after the fifth time using it and never changed how i used it. To add, i also think the pump design should be different. The current design has connections for pump and water coming in on the side where you have the wheel and handle arm to contend with to make connections. Not to mention putting you close to the carburetor for possible burns when still hot. It would better if connections were strait back with no restrictions to work with. Just submitted proof of purchase and registration at same time so waiting for support on direction of issues that manifested early in usage. I chose this product over going back to a long time name brand that worked well for me. Hoping not a wrong decision.

Nightmare

Just took it out of the box and put it together. I followed the instructions to the letter. This is the most difficult power washer I have ever had to start!! I've only gotten it started twice, And had to stop it To take a couple of breaks. I'm on my third start and I'm dying trying to start this thing . I sure wish I hadn't bought this
