We acquired the SIMPSON MegaShot MSH3125 Best Pressure Washer so our professional reviewer could put it to the test on some cleanup tasks. Keep checking out for our complete item review.

When it comes to cleaning, exceptionally sturdy outside cleansing, a garden pipe will not suffice. You need a pressure washer to do the task. Among the leading choices offered? The SIMPSON MegaShot MSH3125 Pressure Washer. It provides an effective 3,200 PSI at 2.5 GPM stream of water that’ll clean up even the dirtiest outside products. We utilized the washer for some clean-up jobs to see if its performance matched its raw power.

Setup Process: Easy with the oil

The SIMPSON MSH3125 comes partially put together. We had to connect the deal to the cart until it snapped into place. Next, we added and joined the wand oil & fuel before firing it up. SIMPSON gives the oil with the power washer. However, naturally, we needed to supply the energy. The oil gets packaged in a soft pouch that can burst if you are not cautious with it. The assembly process took about 15 minutes.

Performance: Great for huge and small tasks

That power tool stands apart because of its, well, power. The water pressure gets ranked at 3,200 PSI (pounds per square inch) when the water flow is 2.5 GPM gallons per minute. The numbers are on the high side for pressure washers (as is to be anticipated from a gas-powered system). Sure enough, the SIMPSON gives a super-strong stream of water that makes it easy to clean even the dirtiest and grimiest products. It cleaned up everything we tossed at it, from a dirt-crusted driveway and a weather-worn deck to a filthy old grill and a mud-encrusted ATV.

The system is so effective. You take care of what you clean up. The 0-degree nozzle may leave marks in the wood of your patio or damage the siding of your house. Even with the milder 40-degree nozzle, you ought to beware when cleaning up a vehicle or bike. You might harm the paint job since the washer’s pressure if you get too close.

Style: No soap tank is a big detractor

There’s little doubt the MSH3125 is a complete power washer capable of cleaning up even the dirtiest messes. When it comes to development, this unit is a blended bag, with some unique functions and some critics that can be discouraging.

What we loved most about the model is its resilience. The frame consists of durable bonded steel, the hose is kink- and abrasion-resistant, and all the essential fittings are brass, which won’t rust or fracture over time. Even the power wand has a brass-fitting with a quick mechanism that lets you rapidly change nozzles (5 are: 0-degree, 15-degree, 25-degree, 40-degree & soap). The cart has rugged 10-inch pneumatic wheels & a compact frame that makes it easy to move the unit around and keep it stable throughout the operation. Another highlight is the 25-foot tube that allows you to clean a broad location without moving the pressure washer every few feet.

A few wrong choices eclipse all these good points: Most noticeable is the lack of a dedicated soap tank. Rather than an onboard soap container, the system has a tube inserted into your soap bottle. Not only did we discover using a tube troublesome, but we also inadvertently spilled our soap bottle a few times. Next is the area of the water connections. They are positioned near each other, making it difficult to add or get rid of pipes– especially if you have huge pipes or use a tube adaptor.

Fuel Life: Sufficient for the majority of jobs

A fuel-efficient Honda GC190 engine powers the MSH3125. The fuel tank carries half a gallon of gas that we found gives an hour or 2 of cleaning, depending upon use.

Noise Level: Quiet for a gas-powered design.

That is a gas-powered design, so anticipate some engine noise while you are cleaning up. The Honda engines are for their reasonably quiet operation. However, they are not as peaceful as an electrical power washer. However, the sound is not deafening, and we were able to talk it over– albeit loudly– while we were power cleaning.

Price: Pricey, however, worth it

The MSH3125 has expenses of around $400. However, you’ll forget about the money you spent after you fire it up and tidy your deck in less than five minutes. You may find cheaper models on the market. However, you’ll likely be sacrificing power so that the option will depend upon your specific needs.

Competition: Depends on your needs

Sun Joe SPX3000 Electric Pressure Washer: 

What the Sun Joe lacks in power. It creates inconvenience. We also evaluated this compact power washer, which offers the same quantity of nozzles and is small enough to be portable. It’s less effective than the SIMPSON system, but it’s likewise a fraction of the price– and we discovered it sufficed for most little home tasks.

RYOBI 3000 PSI Pressure Washer: 

The RYOBI we examined matches the SIMPSON performance. Still, the former offers a practical electric start for people who do not like or physically can not use a pull-string motor. The gas-powered pressure washers have a similar price. However, the RYOBI earned more excellent marks for style and ease of usage in our tests.

Last Verdict

Excellent for complex jobs

The SIMPSON MegaShot MSH3125 Pressure Washer was the very first choice because of its raw power when we had a big task to do. It removed every piece of grit & grime we had around our house with ease. We wish it had an onboard soap tank and a better way to store the long 25-foot tube.
