Simpson Cleaning MSH3125-S

What To Look For and Things To Be Mindful Of
1. Cleaning Power And Engine Size
Unlike in cars in which the power is determined by how much horsepower its engine is able to produce, pressure washer power refers to the maximum cleaning power of the unit.
To simply put, a gas pressure washers power is expressed in CUs or cleaning power units. To get the total CUs of the gas pressure washer, refer to the formula below:
Cleaning Power (CUs) = Maximum Water Pressure (PSI) x Flow Rate (GPM)
On the other hand, the engine size of the gas pressure washer is measured in cubic centimeters or cc, which refers to the total volume of the engine’s combustion chamber. The higher the cc, the more powerful the engine is.
So, what exactly is the connection between the cleaning power and its engine size? You see, the higher the engine’s cc, the higher the amount of pressure it can produce or the higher the PSI of the machine.
The bottom line is that you should check both the PSI and GPM of the gas pressure washer to be able to calculate its maximum cleaning power. An example of this scenario is when 2 units have the same cleaning power but have different PSI and GPM.
Unit 1: 3200 psi x 5.0 = 16,000 CUs
Unit 2: 4000 psi x 4.0 = 16,000 CUs
2. Recoil Starter Vs. Electric Starter
Gas pressure washer with small to medium-sized combustion engines can have either an electric starter or recoil starter (pull-string). But for gas pressure washers with an exceptionally bigger engine, it is safer to opt for ones with an electric starter. Gas pressure washers with an electric starter let you turn on the tool with just a mere push of a button. However, please do note that electric starters are more expensive.
3. Hot Water Pressure Washer Vs. Cold Water Pressure Washer
Recently, gas pressure washers for hot water are gaining the interest of many. This is because as compared to the gas pressure washer for cold water, the hot water gas pressure washers have boilers or heaters in them.
What’s the big deal about having a boiler or heater in your pressure washer, you may ask? Well, why do you think your dishwasher uses hot water when cleaning your kitchen utensils? The same principle is actually applied in hot water gas pressure washer.
The boiler helps to heat up the water temperature for up to 50 degree Celsius. Once the water is heated, it will be easier to break down stubborn stains and grimes. Thus, you can complete the cleaning tasks in less time and with minimal effort (just like when using your dishwasher).
4. Carriage Frame Construction
The carriage frame construction will help you move and transport the unit with ease. This is particularly important if you plan on using bigger units. A big and compact gas pressure washer needs a wheelbarrow-like stance. This will give more room for the machine's engine and pump. Also, the frame has to be made of steel and is welded securely. Lastly, the frame should allow easy installation of the anti-vibration mount.
5. All-Terrain Tire Toughness
Checking the toughness of a gas pressure washer tires is a bit challenging since most modern manufacturers no longer indicate the degree of toughness of the tires.
One easy way to make sure your gas pressure washer can survive all types of terrain is to get a pressure washer unit with heavy-duty pneumatic tires. These type of tires gives better traction on the surface the machine is travelled over, thus less bumping and shaking.
6. Storage Of Gasoline
At first thought, you wouldn't really think storage is an important thing to consider, right? However, you'll be thanking yourself for knowing how to properly store your pressure washer gasoline once the winter season strikes.
During winter, the leftover gasoline in the gas pressure washer tank can harden and cause problems to the combustion chamber of the engine. This is when starting the gas pressure washer becomes difficult, or worse, the machine has to be repaired or replaced.

Frequently Ask Question
1. Why Won't My Gas Power Washer Start?
In gas pressure washers, there are 3 common reasons why a gas pressure washer won't start. Since the gas pressure washer is made up of several parts that work together to make the engine work, you need to make a thorough check-up.

Inspect the spark plug and check for signs of damage.
Ignition Coil Problem:
Make sure the machine's ignition coil is not broken or damaged. If the coil is defective, it is impossible to start the machine.
Check the carburetor for possible clogging issue. This is usually caused by leaving fuel inside for a long period of time. Over time, the leftover fuel becomes sticky, clogs the carburetor, and prevents the engine from starting.
Try cleaning the carburetor first. If the issue is not resolved, replace the entire carburetor.

A gas pressure washer is used in different cleaning tasks, from medium- and heavy-duties to commercial purposes. This includes paint prep, driveway cleaning, and construction site clean-up. For light-duty tasks, opt for electric pressure washer instead.
