High Pressure, Easy Start and operation

Purchased this pressure washer to clean backyard concrete patio and front driveway. Easy to assemble and operate. Cleaned a lot of ground in dirt from the concrete with little effort. All in All, Good pressure washer to have for those jobs around the house. Unfortunately the Spray Gun is made of plastic, (part number 817088-219), and was cracked with a chunk of broken off near the handle. Also when I was assembling the pressure washer it was missing the bolt M6*50, (part number 91811), for the upper holder attachment. I will be contact the company to ask for a replacement spray gun. bolt M6*50, (part number 91811), for the upper holder attachment.

Set up instructions are very good

I just bought this pressure washer and have gone through the set up process. The instructions were straight forward and clear. The only issue I had during set up was my own fault. I over filled the engine oil. The instructions said to do this slowly and I guess I filled it to fast. Anyway, because there are 2 oil fill caps, the problem was easily remedied by removing the fill cap on the right side of the engine and tilting the machine to drain into a small plastic container. I saved the oil for use at a future date. I have wanted a machine with this type of power capability and I can't wait for my first use which will not be far into the future!

Easy assemble, quality product

The power washer arrived in a sturdy box, well packaged and without damage. The assembly instructions were easy to understand and the washer was ready for action within around 45 minutes. My previous power washer was electric and was just okay, but the WPX3400 is at a whole different level. The quality of build and the power the unit delivers exceeds my expectations. Highly recommended.

Excellent Pressure Washer

Bought this item a couple of months ago and have used it to clean my driveway, porch and cement floor under the barbeque gazebo. It works great and is powerful enough to clean the hardest stains. Highly recommend this pressure washer to any homeowner .

Good power for a little machine

My old pressure washer finally quit so I was looking at new ones. I saw this pressure washer with high reviews. I was a little skeptical at first. It didn't look as sturdy as what I'm use to. It is a sturdy little machine! Compact, which is good. It doesn't take up much storage room at all. As long as it holds up, I'm happy. The only cons for me are, I wish it came with a longer hose ( which can be purchased separately) and I wish it had a pressure regulator. All in all, it does a great job!

Simple and Powerful!

Got this as my first pressure washer for my car and for around the house. The pressure and gpm is perfect for multiple applications. Easy to assemble out of the box and simple to use. Built in soap tank is very helpful. Would recommend this for any homeowners

Surprise findings and start on first pull!

I have about one hour of use with this pressure washer. I am impressed! It started on first pull! I started cleaning a retaining wall along our driveway and was amazed at how well it cleaned. Surprise! the retaining wall had beautiful tan color I never new it!

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.

I JUST RECEIVED IT...I don't know yet!

It the pressure washer just arrived today! I have not had a chance to use it. It did smoke a little after turning it off after only running it for about 5 minutes. I was only trying it out to hear how loud it sound during use. I was impressed how it started on the first pull. I am hoping I don't have any leaks or loose parts after the 1st full use. Everything was packaged nicely in the box and easy to assemble.
