Purchased the pressure washer with an additional (2) 100' lines and the pressure regulator. Super simple to put together and use. Definitely awesome to have the pressure regulator when you have this much pressure. Allows for peace of mind when washing company vehicles. The pressure washer is a beast and is surprisingly fairly quiet compared to other pressure washers. Can't wait to see what else it can handle!

The PowerShot PS60843 49-State is an absolute beast of a machine. From the first use, you can tell it’s built for serious work. The pressure is strong and consistent, making it easy to clean driveways, sidewalks, siding, and heavy grime without struggling. It starts up reliably and runs smooth, even during longer jobs. The build quality feels solid and durable, and the mobility makes it easy to move around job sites. It definitely saves time and delivers professional-level results. If you’re serious about pressure washing—whether for business or home use—this machine is worth every dollar.

Just picked this up and got it assembled and running today. Startup was easy and it fired right up. Build quality looks solid and everything feels heavy-duty. Haven't had a chance to run it on a full job yet, but first impression is very positive. Looking forward to putting it to work.

I just bought this last week and we have already used it for multiple projects around the house, including washing all the pollen off of multiple cars and my motorcycle. It has been great at getting them all clean and road ready. I am ready to use it on other projects around my house.

I am a homeowner with 9000 sq ft of concrete, rural property, with big driveway. In addition, I have a large garage, with 1100 sq ft of concrete and a boat garage with 1800 sq ft of concrete. I clean all a couple of times a year and this machine powers my BE 24" Whirl-A-Way easily, gets the job done fast.

Bought this to replace a belt drive that was about 15 years old, wasn’t expecting near the power that the belt drive had but this unit has surprised me. The old unit was 4000 psi 4 gpm and this one’s 4400 psi. 4gpm. I have a large patio and lots of driveway to wash and this machine pushes my 20” surface cleaner great! Very impressed

I have used my machine very few times, and the pump has broken down. I took it to an authorized service center, but they claimed that the warranty does not cover it—even though the pump itself comes with a five-year warranty. I am still waiting for a response, and they have not contacted me.

Great machine for use with a 20" surface cleaner. Starts easily and has plenty of power. Might have a 2nd qt of motor 10w-30 oil to fill the machine from what is included. 1qt barely fills the engine with 1.2 qt capacity. Also, oil drain opening in frame could have been lined up better for servicing.

Have only used it once but so far no issues. Only negative is you have to look up in the manual how much oil to add. In the quick start guides it tells you several times you need to add oil before starting. Just not how much to add. They also sent me 1 qt of oil and that was not enough. I had some so no big deal just something to be aware of.

I’m very happy with this Simpson 4400 PSI pressure washer. It starts up easily, even for a gas unit, and delivers strong cleaning power for tough jobs like concrete, driveways, and equipment cleaning. The included accessories and good instructions made setup straightforward. The price was excellent for the performance and specs. The AAA triplex pump works well when maintained and gives reliable pressure. Overall, a great value and powerful washer that’s easy to use and worth the money!
