Simpson PowerShot Professional 4400 PSI (Gas - Cold Water) Pressure Washer

I toiled over the decision to purchase this pressure washer over its sibling with the Honda GX390 engine for quite a while. The reputation precedes that engine, but this Simpson branded engine doesn't have much info out there... However, I decided that the extra power and warranty with this machine overcame any hesitation I had -- especially since I was able to buy this Simpson machine on sale. That is why I gave it 5 stars for value GREAT price for the features and performance. Until I see that the Simpson engine is as reliable as the Honda one (which I hope it to be) I've given it 4 stars for quality.

The good part: This is WAY more powerful than the 3100 PSI 2.8GPM machine I'm coming from. The extra water it moves with the higher PSI makes any job much less time-consuming, which is what I was looking for. Everything from the wheels, frame, engine, spray gun, and hose seem very durable and commercial-grade in quality.

The bad: The manual omits an important part of the start-up process: Unless you are depressing the trigger on the spray gun while you pull the recoil cord on the engine it doesn't want to start. This sounds harder to do than it actually is, but a word to the wise, nonetheless.

Overall, I'm very pleased with this pressure washer so far. Great customer support when weighing my decision, as well. Keep up the good work, guys!

Bought this product, out of the box it worked for the front of the house. I go to use it again today and it will not turn over. Truly awful.

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.

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.

When I saw the value of the Simpson Pressure Washer I had to purchase it immediately. I love. that it has a Honda Motor. I'm a little skeptical about the pump. I heard "AAA" pumps don't last long, but if I can interchange it with another brand, I'll be extremely happy.

The first time that we used this it stopped running after 1-1.5 hrs of use. It would start OK after 1 or 2 pulls, run one minute, then quit running and this happened each time we tried to re-start. We had used freshly bought non-ethanol gas, stabilizer, and checked the screen going into the tank for debris each time it was filled. We precisely followed all set-up and operating directions in the manual.

Took it to an authorized dealer. Were told there was trash in the carburetor. Got it back, ran it about 1 hour and the same thing happened. Had specifically cleaned out our portable gas can of all gas we had been using and again bought fresh non-ethanol gas and were CERTAIN that there was no debris in the screen after filling the tank. Took it back to the authorized dealer and they replied with the same result. The screen that the gas gets poured through is the finest mesh possible and yet we were told that our gas was putting particles larger than the mesh into the gas tank and we saw no indication of trash when filling the tank. They would NOT consider anything else, like, maybe it arrived with trash in the tank or the carburetor. We wonder just how well it was cleaned out the first time it was brought in.

We are picking it up Monday and wondering what we will do if it keeps going on. Different authorized dealer for one thing but our entire reason for buying this unit was to complete a job before winter season but it has been run for less than 3 hours total and in 'the shop' for 3 weeks total. I have spoken with both the seller of the unit and the manufacturer. The seller will not issue a refund until it is authorized by the manufacturer and the manufacturer will not issue a return unless the 'authorized dealer' says there is a defect. As long as they keep saying there is debris in the system, we have no recourse and will be stuck with a unit that will only run for one hour then needs to be taken in for service in order to retain the warranty. I would like to say this has potential to be a great product but that is not possible if it won't run.

Great pressure washer but needs a better pump as AAA is the worst pump u can get. Other than that it's a great purchase.

Robust, great finish, accurate and reliable operation. Force beyond expectations, making work easy and fast.

I advise you to purchase a turbo tip.

So I've read the reviews before I bought. So my unit shows up in a very well packed carton. I'm thinking how in hell can there be any damage to this unit, short off dropping it off a 10 story building? (old reviews)

Assembly wise is a piece of cake unless you're looking for gasoline, didn't have any. Think I'll send it back, really? Once together and fueled it took two pulls to fire up, almost made it on the first pull. Think I'll send it back.

Now that I have had a little fun with the cry babies out there... This machine is heavy duty. I would buy another one in a heart beat. POWER wise, it has all your ever need. I am cleaning concrete with it and by the way I have one of the other ones also.

Anyway I also have a surface cleaner, (look it up if you don't know what that is) I have turned this machine down a little because it has so much power that it will make my surface cleaner fly. Yes I said fly. So without going into a bunch of stories I will leave it at this:

Buy this unit, I am pretty sure you will not be disappointed. Just order it with gas. Just kidding. Good luck out there.
