Wow, What Raw Power!!
WOW ! This is my second pressure washer, last one (Honda 3800 psi) lasted me over 30 years with a couple of minor pump valve rebuilds. (change the oil a lot) And I 'am a General Contractor/Engineer and use the thing a lot.
Back to this one, it has unbelievable PSI and major cleaning power. 4400 psi makes a BIG BIG difference and I mean BIG ( did I say BIG ?). I think with the 0 tip you should be able to cut sheet metal or drill through concrete!
Engine looks and sounds good, starts within two pulls every time. It is a little fussy if you don't start it the same way every time. (first pull choke second pull no choke/ start) even when hot. Would like to ask the carburetor Engineer What-up , but it does start every time. And when it starts you can tell it was made well.
I bought this and a surface cleaner. And did a large driveway that used to take 1.5 hrs with my 3800 psi Honda, in 20 min with clean-up. It does need a shorter wand, this one 30" is too long (maybe 20"). Oh, get a pressure gauge, it is a ( MUST HAVE ! ) most accessories can't handle this much power (PSI). But make something to hold the gauge upright because under pressure you can not move it, and you will be reading it upside down.
Guess a shut off valve would also be helpful (next purchase). Look forward to 20 years out of this one.By that time I will be 75 and won't want to pressure wash anymore. But for now it looks like I will be doing a lot more pressure washing from now on :)

When I first saw this unit I thought the engine was from a well known engine brand. I was surprised when it wasn't but took a gamble and purchased this unit anyway. I was not disappointed.
The engine started after one pull. The 50 foot hose slid easily over concrete steps. The frame is durable and the pneumatic tires allowed for me to rollover different terrain.
I threw the unit in the back of my truck without any problems when I finished the job.
Pros:Durable, Easy To Use, Reliable, High Quality

"I have always had good experience with Pressure Washers Direct customer service."
I have recommended the Simpson 4400 to several friends! After searching for a few weeks, I am glad I waited and found this one. I have owned the smaller Simpson and know he company to be reliable.
I always did not want to spend the extra for more PSI. I didn't know the difference was so much from my 3100. Saves time and does a better job. Also I am not using detergents. I bought the 4.0 turbo nozzle. It works so well, I don't ever want to be without it. So I bought another.
The engine runs smooth and is quieter than I thought it would be. It starts on the second pull. The pump is heavy duty brass and more than does the job. My use is a little more than residential.
This is a very well built unit and easy to use. I found this to be by far the best deal out there and would highly recommend this to anyone!!!!!!!!! Oh and super warranty!

"PWD has he best deals. Great communication. I bought the Simpson 4400 and the freight was included, what a bonus. PWD uses fast and friendly shipper (R&L) it was unloaded into my garage.
I will be buying from PWD again and have recommended PWD to my friends. THANK YOU"
Did a lot of research being I am a contractor and keep blowing machines up. For the money this machine is super man. It will knock you off your feet.
It starts 1 pull maybe 2 once its initially started for the first run time.
The quality of the machine is outstanding, the hose and nozzle is super duty. Best price anywhere.
Not much more to say- just buy it!!!! Stop looking.
Pros:Price, Exceeded Expectations, High Quality, I'd Buy It Again

Pump Leaks Not Satisfied; Also Very Hard To Start
I have owned many pressure washers within my company, I am very disappointed with the quality. When it first arrived the hose was smashed needed to swap it with one I had after 20 min. the pump started leaking.
It is very hard to start even with the trigger pulled which is very dangerous.
I'm sorry you are having issues with your pressure washer.
Our records show that we called you on 12/15 to let you know we sent out a replacement hose. If you haven't received it, please contact us at 'service@pressurewashersdirect.com' and we'll be happy to track the shipment for you.
AAA Pumps is one of Simpson's brands, so I would suggest giving the folks at Simpson a call at 877-362-4271 to see if the pump leak is covered by their Factory Warranty.
The procedure to prevent vapor lock is to pull the trigger on your spray gun before you try to start the motor, let the water run for a minute or two, release the trigger, and start the engine. This should be done each time to drive the air out of the pump. Since the pump and engine are directly connected, air blocking the pump will make it difficult, if not impossible, to get the engine to turn over.
