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.

Great pressure washer.

I bought this product to replace my failed Troy-Bilt pressure washer, which served me well for 14 years. I am looking forward to this pressure washer maybe outlasting the Troy-Bilt. This pressure washer was easy to assemble. My previous pressure washer was 3000 psi; I am looking forward to the 3400 psi.

Powerful and Easy to Use

Really happy with my Westinghouse pressure washer so far. It was easy to put together, started up without any problems, and has plenty of power for cleaning my driveway, car, and other stuff around the house. The different nozzle options make it easy to adjust the pressure depending on what I’m cleaning. Overall, it feels solid and works great. Definitely recommend it.

Westinghouse Quality

My old pressure washer pump failed and was in the market for a new one. I have two Westinghouse generators and both of them have worked flawlessly so it was a no brainer on getting a Westinghouse pressure washer. This WPX3400 is right what I was looking for. Perfect size for a residential pressure washer.

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.

WPX3400 fits in between Upper Homeowner and Commer

Our verdict after 2 years of usage. Excellent experience so far. This is our initial experience and hope it continues. Pressure washer choice. Choosing between a consumer-grade and prosumer-grade gas pressure washer, we considered what were our specific cleaning tasks and environments. We've experienced the limitations of electric and needed something of an upgrade without breaking the bank. Power. A 212cc engine combined with an axial cam pump makes this pressure washer capable of achieving a pressure of 3400 PSI (approximately 57 times greater than that of a standard garden hose) and a flow rate of up to 2.6 GPM (manufacture claim). Corresponding these values is a cleaning power CU of 8840 Cleaning Units (3400 X 2.6). An extremely efficient machine in its price range. Upgraded to the Westinghouse WXP3400 power washer for the power, durability, and reliability. Soap injection: Detergent storage is ensured by a non-removable 0.5 gal tank. The Westinghouse WPX3400 includes an automatic soap dilution mechanism, allowing detergent to be diluted to the ratio of 12:1 with ease. Connection of a soap nozzle triggers the pressure washer to automatically incorporate the detergent into the water stream. Packaging: Power washer was very well packaged with proper parts protected. Pro: Very user friendly machine Setup was straightforward following the directions. Startup: Installed the supplied motor oil and some fresh ethanol-free gas, started the cold water flowing, put the choke on, turned the power on/off switch to ON and pulled the starter rope of the Recoil Starter and the motor started with the FIRST PULL! Just like is should. No smoke, no rattles, no surging. Best practices. Tip to notice! 1: After you're done using the machine and while the pressure washer is turned off, pull the recoil handle 5 - 6 times. This should remove most of the remaining liquid inside the pump. Tip to notice! 2: After First 5 Hours, Change engine break in oil. Kinda an old school procedure, but it does make a difference. After that initial oil change, follow the manuals maintenance schedule. Tip to notice! 3: Remember, before starting motor to start the cold water flowing into the pump and squeeze the trigger until water flows through it (it will be a slow flow as the pump is not on yet) Then engage the trigger lock and start the motor. Never run the motor with the pump dry. Tip to notice! 4: Put a 5/8 in. Hose Washer with Screen and use them on the pressure washers to avoid damaging the positive displacement pump and plugging the tips. You can still get debris in your hose from dragging it across the yard. It's always a good practice to put the screen directly on the pressure washer inlet. You can get them from any big box hardware store. They are in the plumbing section. Cheap preventive maintenance, just remember to periodically check them. Tip to notice! 5: While running and not spraying water, the pump can heat up very quickly (lack of water cooling pump), you will notice a black "Thermal Relief Valve" draining out the warm water. Keep this valve operational. Check the manual, there is time limit of running the motor without water flowing through the pump. Tip to notice! 6: After your all done and the machine is off, the household supplied water is turned off, the gas is turned off, make sure you press the wand handle to release any residual water pressure in the hose/gun. I noticed this after trying to remove the high pressure hose as the M22 connector was very tight. I thought I had overtightened the connector. But after releasing the water pressure, the connector twisted off easily. CON's: Low oil shutdown = No, doesn't have one Soap tank capacity = 0.5 G Would like to have a clear fluid indicator on tank Intake cold water hose connection points directly toward right wheel, with vibration will cause a hole in the cold water input hose. Outward high pressure hose also directly toward right wheel. had to secure hose to upright frame with a small section of a pool noodle and zip ties to prevent hose failure Conclusion: We've initially used this pressure washer to clean a cement patio, vinyl fencing, and some vinyl siding and were not disappointed and we believe you will not disappointed either. Took off one star for noting having a Low Oil Shutdown.

Nice machine/good price

Nice looking machine, lots of power, much cheaper if I'm comparing to my 25yr old Craftsman model that recently died. Maybe a little too much plastic used for the components though (but that's what helps keep the price low), Sometimes the plastic is fine; for example, my old Craftsman model had nice rubber tires, but a pain in the neck to have to add air every year. This model has large plastic wheels, which saves me that trouble and is just fine for what I'm using the machine for, but certainly doesn't look or feel as good.

Questionable

Just bought it...used it for about 10 minutes and one of the 4 bolts that holds the water pump on completely vibrated out and was laying on the ground...thankfully found it and was able to figure out where it came from and re-attached it...seriously 10 minutes of use (max!). Seemed to run fun and work properly other than that...but its still new...anything can happen at this point if it started to come apart already.

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
