Best Purchase & Worth Every Dollar

I bought this and used it to pressure wash my entire house. The pressure washer was very easy to use and has more than enough power to do the job.

Powerful

Lots of power to this thing. Wish it had electric start as the pull start can be hard to pull. Other then that no complaints. Doublecheck the pump bolts as mine rattled loose on first run. For the money this pressure washer is worth it

Performance and Reliability

I researched gas power washer in depth with primary concern to find a quality unit with a pump that will last. My WPX3800 from Westinghouse filled the build on both fronts using a Triplex Pump that will last and can be rebuilt.

Great in-between commercial and residential

I bought this a couple of weeks ago, and it has worked great. The pressure it provides is excellent for use between commercial and residential applications. It works great on concrete driveways and cleaning off heavy equipment.

Extreme Power

I have over a thousand feet of 10' and higher rock walls around my property and was looking for a pressure washer that would make it easier to clean the rocks. I had been using a 3600 psi pressure washer and was reading that stepping up to a 4400 psi pressure washer makes a big difference so I purchased the Westinghouse WPX4400. Initially, the pressure is great. When I first pulled the trigger it knocked me back the pressure was so great. I did not turn down the pressure knob, but will probably do so when I do not need so much pressure. The manual covers 3 different models (the 3600, 3800 and 4400). It is confusing when dealing with the 4400 since there are parts not even needed on the 4400, but this is not explained so it was a little frustrating trying to follow instructions that did not even apply to the 4400. It would be helpful if the manual explained when instructions do not apply to certain models. The first time I went to start the 4400 the compression was so high that it would not turn over. After five pulls the handle came off due to the knot pulling through the handle. After fixing the handle I tried to start it again while my wife held the trigger down on the wand. This removed some of the pressure and it then started. This should be explained in the manual that for the 4400 it is necessary to depress the trigger to reduce the pressure and compression. After the first time I just held the wand myself and pulled the trigger and was able to start the pressure washer myself. Overall, I am pleased with this purchase.

Good power washer.

I am doing power washing for 15 years, my old power washer broke. So I bought this one (WPX 3800) and I am very impressed. Weight is no problem, power abundant. I overfilled oil and had some issues, but service call was excellent. Evidently there was some oil in the engine, so when I "filled" it, was to much. But great product, great service.

Good Pressure washer

Just unboxed it. I am pleased. Easy assembly ( you'll need allen wrench and a 10MM). Started on the 2nd pull from dead empty! The QDs on the hose and handle make storage a lot easier! Good pressure and flow. Took a bit to purge out the air in the pump (surged for a few minutes) but then settled down. You will get some strange smells as it warms up and burns the paint off the muffler. I'd give it 5 stars but I'll reserve the last star until after it's been used for awhile.

Best Power Washer

We have a very long driveway that needs cleaning annually! I needed a better Power Washer to thoroughly clean our driveway as my old one just didn't do the job. I found the solution with the WPX3800 which does a fantastic job! Thank you Westinghouse!
