Simpson Megashot MSH3125 Overlook

The Simpson Megashot MSH3125 is a high-quality, Honda-powered gas pressure washer famous in the market for homeowners. It can produce 3200 PSI pressure at a 2.4 GPM flow rate and is ideal for cleaning away tough stains and grime, removing oil stains, and mildew. 

With so much buzz about this gas pressure washer in the market, I decided to purchase it to clean my driveway and garage. Let’s see how it worked!

Unboxing and General Appearance

To my surprise, it was beautifully packed with thick foam and sheets to protect it from carriage wear and tear or damage.  I must admit that the Simpson Megashot 3125 looks rather bulky and not very cool. But once you examine its power and effectiveness at blasting away tough stains and caked mud, you might not have too much trouble using it.

The rubber supports near the wheels make the machine stand firmly in the wake of heavy vibrations while pressure washing. Moreover, this gas pressure washer is not too heavy with a weight of just 65 pounds. Therefore, you can single-handedly and easily assemble it and transport it to your truck.

Easy Assembling Is the Relief 

Simpson Gas Pressure washer comes almost ready to be used and takes very little to completely assembled. There is no engine oil in the machine when it comes. However, the company has provided the sachet of oil and you just have to put it in the engine. Next, I attached the wand with the pressure hose efficiently.

There is an easy-to-lock handle that will adjust the panel with a click sound. The engine oil is provided by the company but definitely gas is on us. Once the gas tank was filled, I connected the pressure hose and pump with a little difficulty because the connectors are a little close to the body and difficult to tighten.

On the whole, the assembling process with Simpson Cleaning msh3125 gas pressure washer almost took 8 to 10 minutes which I think is a fair deal in assembling such a big unit.

Amazing Features of Simpson Megashot MSH3125

Packed with so many features I will be discussing some of the important ones below:

Starting the Engine Is Easy 

The recoil engine is sometimes a difficult task for some to start because pulling the cord may strain their necks or shoulders, but Simpson Megashot msh3125 is quite good at it. The ripcord was soft enough that it started the first time.

Note: Always pull out the choke before starting. It is a metal ring that must be pulled out before pulling the cord for a perfect start.

Noise Level

When you compare gas pressure washers with electric pressure washers, they’re obviously noisier than electric pressure washers. But here, Simpson MSH3125 is less noisy than electric pressure washers due to its highly efficient Honda CG190 4-stroke powerful engine and its compact body shape.

Other Technical Features:

Simpson Megashot MSH3125 a 3200PSI and 2.5GMP gas pressure washer has the following technical features:

Strong Honda CG190 Engine

Since gas pressure washers are powered by engines, they require continuous fuel and refills. This Simpson gas pressure washer uses a Honda CG190 4-stroke engine which is efficient enough to produce 3200 PSI of pressure with 2.5gpm of water flow.

The fuel tank of the Simpson MSH3125 gas pressure washer almost holds 2 liters of gas for cleaning operations.

Extraordinary cleaning power. 

Simpson Cleaning MSH3125 perfectly blasted away dirt and grime from any surface with its great combination of 3200 PSI of pressure along with 2.4 GPM of water flow rate.

It’s powerful and the maintenance-free engine provides enough energy to produce this massive pressure and water flow. 

This is a residential power washer but if you are looking for a commercial pressure washer with bigger tasks at hand you need big machines. Before buying one, you should compare 4GPM and 8GPM pressure washers for better cost analysis.

Long Pressure hose

This gas pressure washer comes with an extraordinary MorFlex® ¼-in 25 feet long hose which helps to move freely across your garden or lawn for perfect cleaning results. Its long hose is made from high-quality abrasion and kink-free material that ensures its long life. 

However, there is a little downside to it. This pressure-washing beast does not have a hose reel to keep the hose organized and well-arranged when not in use.

Large Wheels

Moving across your home is sometimes difficult due to the type and shape of the wheels of your pressure washer. This is because the hard shape of the wheels does not allow them to move freely along grassy and muddy areas.

However, Simpson Mega shot 3125 pressure washer comes along with large rubber wheels which allow it to move without difficulty on every type of surface and terrain.

High-quality Material and Connectors

The Simpson 3125 is a durable and sturdy pressure washer. From the first look, it’s obvious that the body of Megashot MSH3125 is made from a high-quality welded steel frame and powder-coated for a smooth and shiny finish.

Moreover, it also has great-quality brass connectors for all of its connections. This high-quality material ensures the long life of the pressure washer and its accessories.

5 Quick-Connect Nozzles

You will find five separate spray tips included with this pressure washer. These include a 0°, 15°, 20°, 40°, and soap nozzles.

With the quick-release function at the end of the pressure wand, these spray tips can be easily attached to the wand or the pressure gun.

Few Drawbacks

There are a few drawbacks to this amazing pressure washer besides its fantastic features. For example, it does not come with an integrated hose reel for proper storage of the pressure hose.

Additionally, this gas pressure washer does not include an onboard detergent tank, contrary to many of its competitors. If you want to use detergent or soap for better cleaning results you have to connect a detergent bottle to the pressure gun using a tube. However, this tube comes along with the pressure washer.
