Purchased the Westinghouse WPX3400e mainly for washing cars and other light duty things that work better with the start/stop technology that electric pressure washers provide over their gas counterparts. I also have a gas WPX3400, they are night and day different machines, each with their own strengths and weaknesses. The WPX3400e replaced a different brand electric pressure washer I owned, mainly because the other one used a proprietary pressure hose connection and I require a 50 foot hose which was not an option with the other. The WPX3400e uses standard M22-14 connections. Setup was simple, but note, with a 1/4 inch 50 foot steel braided hose on the holder, the balance is almost tipsy. It didn’t tip, but it’s close. It is not a problem in operation, just in storage.
The specs are overrated like all consumer brands. With no tip installed, the max GPM through the wand was 1.5GPM. The 0 degree and 25 degree tips are 1.45gpm/orifice. They both put out 2300psi @ 1.0gpm. The 15 degree tip is not labeled and put out 2500psi @ 0.9gpm, so it has a smaller orifice than the other 2 labeled tips, maybe 1.25. The Turbo nozzle provided 1000psi @ 1.5pgm.
Since I intend to use this for car washing, I wanted lower PSI and higher GPM, I tested with 3.0 tips, and the results were 1000psi at 1.5gpm. I was happy to see it putting out the max GPM it’s capable of, but wish the max was closer to the advertised 2.0gpm.
I purchased 3rd party 2.5 tips, but when tested, they were at least 3.5 tips (700psi @ 1,5gpm) so they are going back.
For comparison, the gas WPX3400 with 3.0 tips put out 2700psi @ 2.5gpm, with a max static pressure of 3200psi (running no trigger pull) and 3.0gpm max with no tip. It’s a massive but expected difference.
The unit is fairly quiet and the start/stop function works well. It has a soft start, so the pressure ramps up over a few seconds, and when you release the trigger, the hose pressure releases, unlike my last electric pressure washer, that maxed the pressure ready for a trigger pull. I don’t know that I have a preference, it’s just different. The WPX3400e does draw more than 15amps in operation, It maxed out my kill-a-watt and sent it blinking above 15.15a. That’s not just initial in-rush current, but operating current. It did not trip a 20a breaker which had nothing else on it at the time. I washed my wife’s car with 3.0 tips and it went well. I also used a foam cannon and that performed well. I had to adjust the knob on top since the pressure and GPM were different from my last electric pressure washer, and it produced great foam once dialed in. All in all, I like the WPX3400e, but I do wish it had a little more weight up front so it wasn’t so tipsy with a larger hose on it. Adding this review for the “Bonus 5 spray nozzles” hopefully they send 2.5 tips!
