Powerful, Reliable and Great Price!

I shopped around and selected the WPX340 for three reasons: the reviews from others, the power, and the cost. This has delivered on all three! Just a well-designed power washer. Make sure you read all instructions for the best experience and to protect your washer!!!!

Detailed initial review of Westinghouse-WPX3400

Our verdict: 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 from SunJoe's Electric pressure washer for the power, durability, and reliability that Westinghouse gas powered pressure washer is known for. 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. Power washer was very well packaged with proper parts protected. It was almost 100% assembled Pro: Made/assembled in the USA with parts from other countries 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. 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.

Solid performer, great features, easy start

I bought this a couple days ago. The pressure washer works great. It is easy to start, easy to use, and easy to store. I also purchased the pump saver to flush the pump to ensure a long lifetime of use. The pressure washer makes power washing the sidewalks, house, and cargo trailer very easy and fast. This unit is a 3400 PSI and is perfect for my needs. I recommend this unit as it seems like it is very high quality.

A Godsend

We just bought our new pressure washer after our latest Hurricane Milton hit our area in North Port, Florida just a few weeks ago. We are still cleaning up but with the additional tool of our new pressure washer, cleanup is moving along. We highly recommend this product.

Perfect for everything I need around the house

I got this gift for Christmas and it is going to work perfect. It has all the needed nozzles. This is going to allow me to clean my entire house, clean my vehicles, and other hard to reach areas. Very pleased with all the details. Also, a friend suggested using the power washer for blowing leaves and it works REALLY well for that.

WXP3400 PSI Power washer

It was shipped on time with detailed instructions. It was easy to put together and I had it up and running in just about an hour. It works as advertised and it's light and easy to move around. Also, it's powerful enoughto take up grease spots in pavement and clean high areas on a house.

Super powerful pressure washer!

I borrowed this pressure washer from a friend and was impressed. Bought my own a couple days ago. Really easy to put together. Took husband about 10 minutes. Came with the oil and several nozzles. My favorite part is has a place to put the wand & hang the hose. Large wheels makes it easy to move around. Has a stopper in the front so it doesn't roll. Love the soap dispenser makes life so much easier.

Easy to set up and use

This was easy to assemble and the instructions were pretty clear. It did a great job of pressure washing the pollen from my new house. I like the fact is has a reservoir for the soap because a lot of pressure washers I looked at did not have that. I had some issues with starting it at first, but that seems to have worked itself out now.

Best Gas Pressure Washer

I bought this to replace the ever so tiring mess of RYOBI pressure washer. In comparison this one works amazing!. The ease of setting up is easy and even my teen can now was our cars and outside of the home including the driveway and sidewalk. Looking forward t my new brand WESTINGHOUSE!

Power Horse

Works perfectly right out of the box, following set up instructions. I bought this for the name brand as well as convenient of the nozzles and the durability of the hose even though it's lightweight. This pressure washer is easy to move around and very sturdy. Stays in place as I'm using it. Soap container is perfect size for the job that I do at my house. I highly recommend this power washer.
