Why Choose Simpson?
This brand provides professional-grade pressure washers in the 3000 to 4000 PSI range as well as affordable lower PSI options, including 2600 PSI pressure washers.
OEM Technologies Axial
OEM technologies axial pumps are some of the best pumps on the market. These pressure washer pumps are efficient and offer top performance with stainless steel pistons to prevent leaks. A stainless steel unloader is also present and requires little maintenance.
The MorFlex hose is specific to Simpson pressure washers. This hose has dual o-ring options so that you can use both 14mm/15mm connections. It also is made of durable polyurethane material for maximum durability.
Most Simpson pressure washers have pneumatic tires. Pneumatic tires are broader and longer than typical cushioned tires. Pneumatic tires are best for outdoor settings and are more durable.
Quick Connect Nozzles
Simpson offers quick connect nozzles on all of their pressure washers. These quick connect nozzles are easy to attach, install, and disconnect, making washing sessions easier for users.
Multiple Engine Types Available
Pressure washers come in two different engine types: gas and electric. Gas-powered engines are able to produce more power and therefore have higher PSI ranges. Electric-powered engines are more affordable and compact but provide significantly less power. Electric power washers can be used indoors. Simpson sells both types of pressure washers.

Operating a Pressure Washer
To operate a pressure washer, begin by choosing the best spray nozzle for your cleaning task and screwing that nozzle on to your pressure washer wand. Then, connect other accessories such as a chemical injector and add your detergent.
Run water through your pressure washer for one to two minutes to ensure that you do not have air in your hose. Then, start pressing the wand trigger to mix detergent and water. Now you can start your pressure washer’s engine and start washing. This video from Dale shows the process more in-depth.

“Pulled it out of the box, followed the easy instructions and was using it in just a short time. What a “beast!” I started with the hardest thing I have to clean which is my driveway, located below several oak trees. There was 14 years of grime and tree sap on the concrete and my new Simpson cleared it away easily. Used it this past weekend with the broadest tip to clean the screens on my sun porch, and again, did an excellent job."
Users have reported that the included hose is not durable and may need to be replaced within a few months. Customers have also noted that the spray trips from various nozzles do not stay in the assigned holder and often fall.

“First of all, I did enough research to cause my brain to ooze from my skull, and when I finally decided to go for this guy, I still had my doubts. But I have to say it’s surpassed any expectation I had of it to get the job done. It’s already been worth the money and it’s super easy to operate. The Honda motor was a big selling point for me, and it does not disappoint. One pull and the motor gets to work right away. It cleaned my deck, sidewalk, and garage floor with ease."
Users have reported that this unit vibrates because it is lightweight, though this doesn't affect the efficacy of the machine. The wand is also made out of plastic parts and is less durable compared to the rest of the device. If you want a high-quality pressure washer that is powerful but lightweight, then this is the best model for you.

Dimitri wrote on
“This is the perfect little pressure washer. It was all but assembled already in the box. Operation is simple — connect the water supply and pull the line. The engine starts on the first pull every time. The first time I used the washer, it turned a 15-year old mildewed gray fence into brand new. Each and every cleaning project has gone off without a hitch."
This model does have a shorter warranty compared to other more expensive Simpson pressure washer models with a 2-year limited engine warranty and 1-year limited pump and frame warranty.

“I purchased this unit about a month ago to replace a 1700psi electric unit which gave up the ghost. The Simpson exceeded my expectations, and made short work of cleaning moss and mold from the face of a white ABS fence in my backyard. Cleaning the 35ft x 6ft fence took about 30 minutes, and removed the grime easily using the 20 degree tip held about 6 inches from the surface. The washer, although gasoline powered, is quieter than I expected."
Users have reported that the brass connectors on this model are not as durable as other models and may need to be replaced if a leak appears. It is also said that the wheel guards may need to be realigned. If you want a quality gas-powered pressure washer that is affordable and portable, then this is a great option.
5. Simpson Cleaning 61016
best 2300 PSI Simpson Model
2760 (psi x GPM)
Yes, one-year limited warranty
Instead of purchasing gas and maintaining an oil tank, users simply plug in the electric pressure washer to an available outdoor outlet. This electric ease can be a strong selling point for homeowners who want practicality and convenience. This model is also highly portable and affordable. An OEM Technologies axial camp pump offers a 1.2 GPM flow rate for this 2300 PSI model.
The high-pressure gun wand has an ergonomic handle for all-day use, and the steel frame on this model arrives fully assembled. An onboard soap tank is easy to use and can hold one full gallon of detergent. Sturdy 10" flat wheels are easy to roll over grass and gravel. This model does have plastic parts and lower PSI power compared to other Simpson pressure washer models. The lower PSI power on this model, however, is the tradeoff for a portable, affordable, and electronic convenience model.
6. Simpson Cleaning ALH4240
top of the range
16800 (psi x GPM)
Yes, 3-year limited engine warranty, 2-year limited pump warranty, 10-year limited frame warranty

“I purchased this unit about two weeks ago and have used it about four times. Starts on the first pull every time and has lots of power. I use a BE orbiter to do driveways and patios. With the Honda engine and CAT pump this is serious."
This unit is heavier than other models at 128lbs and certainly more expensive, but you can’t find a more powerful pressure washer model. This model is perfect for homeowners and commercial owners who want a powerful and effective pressure washer with high-quality build parts.
Comparison to Other Pressure Washer Brands
Simpson pressure washers are considered the premiere pressure washer brand along with DeWalt, Briggs & Stratton, CAT, and Generac. Simpson, however, actually makes DeWalt and Briggs & Stratton pressure washers on their Simpson pressure washer assembly line.
These three brands are, therefore, comparable pressure washer options. DeWalt tends to be a better choice for homeowners, while Briggs & Stratton offer professional-grade pressure washers. Simpson has been manufacturing high-quality pressure washers and other outdoor equipment for more than fifty years.
Simpson creates both affordable homeowner models and expensive professional models (top-of-the-line for businesses and homeowners). If you want the best pressure washer that money can buy, then choosing a Simpson pressure washer is a smart move. If you want to save money and purchase the cheapest model, we recommend looking at Sun Joe, Greenworks, or AR pressure washers.
Maintenance & Troubleshooting
Taking care of your pressure washer with regular maintenance will help your pressure washer last. When you have finished using your machine, make sure that you rinse all of the cleaning solution or detergent from the machine. Then, disconnect the hose and spray gun as well as wand extension. From here, drain all of the water from the pump. Then add a pump lube, also referred to as a "pump saver," and place that in the pump inlet.
To avoid leak problems, we recommend purchasing silicone plumber's grease to use on your hose connectors to prevent cracking and tears. Connectors are often one of the first parts to break down, and keeping them lubricated can help to avoid this problem.
Two of the most common troubleshooting problems that we see involve the air filter and the oil level in your pressure washer. If your pressure washer isn’t working or has low pressure, check your air filter. If it is damaged or dirty, try replacing it. Then check your oil level. Change out the oil if your oil is old or the oil level is low. If these two adjustments do not work, it’s time to call a professional handyman.

What are the steps for winterizing my Simpson pressure washer?
There are several steps required for winterizing your Simpson pressure washer. To start, protect your fuel engine by flushing out the water in your pressure washer pump.
