Awesome machine

Bought this unit last year and it has preformed flawlessly each time. I really like the 4 GPM water flow. Washes away the stuff you wash off. Great Honda engine, first pull start ! I really like things that start when they are supposed to! I agree with the idea of a swivel end that connects to the wand. That would be a good idea. I also like the long wand. Easy on the back! I looked at several pressure washers and after all the research and comparing of different models and brands, I am so glad I went the extra money and got this heavy duty unit. Easy enough to handle on the little jobs and is a beast when it comes to the tough stuff. I would buy another one of these with no questions. Get you one. You will be glad you did. And no I am not a Simpson employee. I just really really really like this unit.

Great machine

Used twice since purchased a month ago. I was disappointed it did not take out rust stains in the concrete using the 40 degree nozzle. Didn’t try the 25 degree since it might remove concrete. Has a kick when using. Started with one pull. Followed instructions to the letter. Hold trigger while attempting to start. Depending on project I used one gallon gasoline at a time with gas protector as instructed. The machine ran out of fuel and no worries of gasoline issues having it sit unused for over 30 days.

GREAT PRESSURE WASHER!!!

I ordered this for general use around my home including cleaning siding, concrete, my tractor and its equipment, plus getting river mold off of my boat. It does a great job. It was very easy to assemble and I had it ready in just a few minutes. Make no mistake. This washer is a brute!

Works great

I bought this to replace my old power washer of many years and I wish I would have traded up sooner. This unit starts perfectly and everything works perfectly. The only problem for me is that I am in my sixties and the unit is very powerful, to help with this I bought the extra handle grip to use and being able to use two hands makes it a lot better.

Powerful and a Time Saver

I bought this to pressure wash my house and driveway. Using only the green tip it works great. The best thing about all this power is time. My son in law has an 1800 psi electric pressure washer and if I would have used it on my project I'm guessing 12 hours. With the 4400 psi I did the entire project in 4 hours.

That's great to hear, Mick1956! We are glad to hear you were impressed with the performance of your 4400 PSI pressure washer & it delivered power to save you time on the house & driveway. With a driveway on the list, you might be a great candidate for the surface cleaner attachment as well - it is a real timesaver on large surfaces (link below.)

Really powerful!

Brace yourself before you pull the trigger, this baby will knock you on your butt. I am able to rinse 3 story gables from the ground with just the 30” extension. My 12’ extension wand and the soap nozzle applies the solution to that height. I added a 5000 psi gauge and, sure enough, I get 4400 psi with the Simpson motor using a 100’ hose. The pull cord location is a little awkward. The entire unit wants to turn as you pull. I put my foot on the wheel to hold it still but watch that you don’t damage the valve stem like I did. I wish it had an optional battery starter, I’m in good shape and I have to pull real hard for a one-pull start. When shutting it off, bring the wand back to the machine with you because you need to pull the trigger to release pressure if it doesn’t start on the first pull. The unit is well balanced and easy to roll up a ramp into my van. This unit paid for itself with one job. Of corse it was a big place...

Not for the average user

I bought this unit for two reasons, Honda engine and power. I can not stress that in the hands of an inexperienced user the probability of damaging something is high. At 4200 psi with 4.0 gpm this unit has some serious kick, you will get a work out after an hour of use. Proper care and periodic maintenance and this pressure washer will last for years.........again proper upkeep. If you got one and it did not work right out of the box more likely it was damaged during transport. Any review from someone down playing this units capabilities or its quality is coming from and average user and not professional.

Amazing

I bought this machine just under a month ago and I could have not been any more impressed. My machine did come with two scratches one on the pump and the other by the pump oil cap but not a big deal (probably just from shipping). I have used it twice already probably running about 5 hours total. Had the pressure gauge set in the middle and the throttle only up to half way just to ensure break in period was smooth and even with that it was more than capable with what I needed it to do. The wand and hose with the quick connects were definitely a huge upgrade and super simple. Overall I do not think anybody could go wrong with this. From the once a year user as a homeowner or even a business owner could get some serious work done with this machine.

Great Unit

Worth spending more to get a commercial grade pump and honda engine. This unit should last a very long time assuming you take good care with it. I wanted at least a 4gpm pump so i can clean faster. One thing to keep in mind is to turn off motor if not spraying for more than 1 minute. This will greatly add longevity to your pump life.
