Simpson Pressure Washer Buying Guide

Simpson Pressure Washer

Buying a pressure washer can be a bit tricky. As you will use it for a few years if it’s not a good one, it will be a big waste.

That’s why, just to make sure you don’t waste your money and make a wiser decision, we are giving you a useful buying guide, which will help you decide which one you should get.

There are some key factors that will help you to find the best one for you. Which are-

Type of Simpson Power Washer

Simpson power washer is available in two types. Which are-

  1. Electric Pressure Washers
  2. Gas Pressure washers

Electric pressure washers are perfect if you want to focus on smaller tasks. These are quieter and produce almost no sound. It’s also lightweight.

However, these are not portable, and mostly these are not powerful. If you are using it for smaller tasks like cleaning the backyard or terrace’s furniture, siding, or vehicle, then you can go for it.

On the other side, Gas power washers are great, powerful, portable, which makes it able to handle big and tough works like cleaning floors, the stubborn surface of concrete, exterior siding of your house, etc.

Using a gas pressure washer isn’t as easy as using an electric pressure washer! Some power washer has a pull-in start, which means you must keep pulling it until the engine gets started.

Also, there is some washer available which has an electric starter feature. However, this engine needs regular maintenance to avoid breakdowns.

Simpson uses the powerful HONDA Engine, and for a better cleaning experience within no time, you should choose Simpson gas pressure washers for portability and better performance.

PSI GPM and calculated CU

PSI, GPM, and CU are the three most considerable terms when choosing a power washer. The power decides what sort of tasks can be done by this.

With PSI it means, Pressure per square inch. A medium-range power washer can have 2800 PSI.

GPM means gallons per minute. A medium-range pressure washer can have 2.3 GPM.

CU is the multiply result of PSI and GPM. CU means cleaning the unit. The CU of a middle-range power washer is PSI x GPM= CU, following that, 2800 x 2.3= 6400 unit.

So, the cleaning unit is 6400. The higher the CU is, the faster it cleans more areas in a short time.

Choose a Pressure Washer Based on the Task

With the PSI and GPM, we have divided the pressure washers into four different sections. Such as-

For light and small works

1300-1900 PSI and 3 GPM. These machines can do small tasks. Most of the electric pressure washers are available with this requirement. These are termed as small pressure washers.

However, these aren’t that powerful, and it’s not recommended if you have any more significant tasks to handle!

For the medium level of works

2000-2800 PSI and 2-3 GPM. We’ve reviewed one within this power range. These are good for handling your household and shop cleaning works.

However, these are perfect for small and regular usages, but for significant or professional works like cleaning a surface on concrete, siding, etc., it’s not recommended!

For professional works-

Professional works like graffiti removal, extensive cleaning, industrial cleaning, siding, etc. commercial-grade power washers are recommended.

2800- 3600 with 2.5-4 GPM are ideal for performing big tasks. However, these are not only for commercial tasks. You can use these for household purposes as well.

Cold vs. Hot Water Pressure washer

Cold-water pressure washer

These are less expensive and perfect for DIYers and household works. The cold-water power washer is best for losing paint, cleaning cars, and performing all the household works.

Hot-water pressure washer

These are ideal for industrial uses. These are expensive but work faster than a cold-water pressure washer, and it’s difficult to control.

Overall, for household purposes, a cold-water power washer is recommended.


Before investing in a power washer, consider the engine. Check the engine’s CC. If you have a good budget, then choose washers with a Honda engine.

These are powerful, comes with a long-time warranty, and one-start performance will make it a hassle-free experience.


Simpson comes with two sorts of pumps. One is an Axial Pump, and another one is a triplex pump.

Power washers with axial pumps are the best option for the homeowner. It has OEM technology that makes it maintenance-free.

On the other hand, triplex pumps are mostly used in commercial and industrial pressure washers. It’s super-efficient and has a long life.

On-board detergent tank or soap bottle nozzle

Sadly, most of the best Simpson power washer doesn’t come with an onboard detergent tank.

However, almost all the Simpson power washers (that don’t have an on-board detergent tank) have a tube where you have to attach a soap bottle. In these washers, they use one gallon of soap and seven gallons of water.


Well, all the Simpson cleaners are made with welded steel and have thermal relief. The washer’s body is also powder-coated, which helps from corrosion.

So, yes, when it comes to building, choose the washers made with steel and have thermal relief.


Simpson power washer has a different warranty module. They don’t provide a full pressure washer warranty.

Instead, they offer different times to other parts. Like for engine three years, for body one years, for accessories 60 days, etc.


Before getting a pressure washer, check what accessories you are getting. Basically, Simpson provides accessories like a hosepipe, wand, etc. You may have to pay more to get these accessories.


The pressure washers of Simpson have adjustable nozzles that will help you to adjust the water pressure. Nozzles of Simpson power washer has five adjustable settings, which are-

0 degrees – this is the most powerful setting. It can cut anything with water speed. That’s why most of the professional doesn’t recommend you use this.

15 degrees: As 0 degrees is not recommendable, most people use it at 15 degrees for heavy cleaning.

25 degrees: This is used for normal cleaning.

40 degrees – This is for cleaning regular items like furniture, vehicle which require low water pressure. To avoid damaging your valuable car or other items, this is highly recommended.

65 Degrees (soap)– In this setting, it provides soapy water in a 7:1 ratio.

Before getting a washer, make sure it has all five nozzles, which will make your cleaning experience easier. Also, make sure you adjust the water pressure wisely; otherwise, you’ll end up damaging your items.

So, these are the consideration you have to keep in your mind before choosing a Simpson power washer.
