Simpson Megashot MSH3125 – An Unbiased Review

The Simpson Megashot MSH3125 is a high-quality, powerful 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 removing mildew. 

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

Unboxing and General Appearance

To our surprise, it was beautifully packed with thick foam and sheets to protect it from carriage wear and tear or damages.  We must admit that 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.

There are rubber supports near the wheels to make it 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, we have attached the wand with the pressure house efficiently.

There is an easy-to-lock handle that will adjust in 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, we 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 a whole, this assembling process almost took 8 to 10 minutes which we think is a fair deal in assembling such a big unit.

Amazing Features of Simpson Megashot MSH3125

Packed with so many features we are discussing some of the important features 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 was 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

However, this time also depends on what you use the machine for. The fuel tank of MSH3125 pressure washer almost holds 2 liters of gas for cleaning operations.

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.
