I purchased the XP 3400, the specs said maximum pressure of 3000 psi, works well, however, the pressure is not even close to 2500 psi with the turbo head, I will contact Westinghouse to see if there is any way to regulate or increase the pressure.
I just bought this Westinghouse WPX3400e pressure washer and put it to the test cleaning my driveway with the Westinghouse surface attachment. There was ample power and exceed my exceptions. Almost effortless.
We bought the electric pressure washer not knowing it was electric but once we started using it, we were very impressed with the power, the quietness and the light weight, it was easy to maneuver around and the turbo nozzle works great. Does the job we needed it for.
I was looking for an affordable, powerful pressure washer. Although it is only 2700 psi it does a great job. Would definitely recommend purchasing this unit!
