I purchased the WPX4400 a couple weeks ago and one thing is for sure... I've wasted a lot of time, energy, and money over the years trying to remove grease and oil stains from the concrete around our diesel repair shops. The WPX4400 makes this task SO MUCH easier! I should have made this purchase a long time ago!

I have used this for 10 hours so far and it runs great with lots of power and flow. I found starting it when it is hot is best done by removing the nozzle from the QD and just squeeze the trigger and let water flow from the QD. It give the least back pressure on the pump.

I've only used it once, so take that into consideration. Easy to assemble. The quick start guide should include more of the important steps that are in the manual... If it's not enough to use the quick start guide, then why include one? First start was difficult, the instructions show the speed lever to the right, but it needs to be to the left. Once started, it's not as loud as I expected, which was a nice surprise. The different nozzles work well.. (I haven't used the soap one yet.) I wish it came with a 50ft high pressure hose, but other than that no complaints. Easy to maneuver and handle. Works as expected. Still a lot more testing before I can give it a full thumbs up, but so far, so good.

Bought a few weeks ago. It's a big engine to pull start, and a bit difficult at first, but keeping low pressure in the tank is key. Easy to assemble as well, and it works well. Complaint is the written (and on-line) manual does not match the new build of this machine. So a few things, including how to use the cleaning solution tubes, is not included, nor intuitive for those of use who have not had a gas power washer before. Due to the out of fate manual, parts listing etc has it's issues. Overall, I think machine is (can be) great. I just don't know how to use all its features.

Just purchased this and it clearly is built to last. Hose is 'real' not that hard plastic stuff. Love the quick connect of the features of the spray nozzle. Attachment ports are easily accessible. Well built with clear identification of caps etc. for maintenence.

Satisfied with the power of the unit although it came without the key way installed on the pump. Fell out when I opened the box. Had to install myself after calling the factory. Disconnected 4 bolts on the pump and installed the key on the motor shaft. Also, this pressure washer is a beast to crank, but when it's running it does a great job on most anything, concrete driveways, vinyl fencing etc.

just purchased, wanted a stronger unit than what is the normal purchase for people my last was a unit that was a 3100 unit was ok had some issues over the 7 or so years. hoping this unit will be better. .3 more gpm and 500 more psi. also i am going to use a 3/8 hose. if you look up hose fiction loss you will be amazed at how much is in a 1/4 hose for 100 ft. at this GPM flow.

On first use, 2 of the bolts for the pump motor vibrated out and fell to the ground. All of the bolts on the pump motor were not tightened down. After tightening these bolts, the pressure washer works great. Would have been 5 stars other than this.

I searched for a long time for a new pressure washer. I needed something reliable with low maintenance because I need to pressure wash 2-3 times per year. I also needed a lot of power because I live on an island with a lot of mold and have an elevated house. I've used this new pressure washer twice and am super impressed. It is the best pressure washer for the money.

It works great! I found it a little tough to crank. Not enough to dock a star. I'm old and it's probably just me. The soap tank is a little awkward as well. Those things aside, it does the job really well. It's very easy to use once it's running and the hose is long enough I don't have to reposition it very often.
