Immense Cleaning Power

No matter the type of surface you intend to work on nothing, is out of scope for the Simpson MSH3125. This unit relies on a powerful 3100psi Honda GC 190 Engine that delivers a stream of uninterrupted airflow. At a flow rate of 2.5 GPM, you should be careful that the forceful stream of water doesn’t pierce skin or cut through your protective gear. The Simpson MegaShot will save you time and energy when cleaning deep-down dirt and leave your surfaces looking as good and new.

This accomplished pressure washer uses gasoline to produce power as opposed to electricity. This means you won’t be limited to working around sockets and saves you the frustration of frequent charging and replacing batteries. The 25 foot flexible polyester hose ensures you can reach anywhere you want while cleaning without straining.

Additionally, five different quick-connect nozzles made of stainless steel allows you to easily select the best suited tool for your project. Including the various nozzles saves you the cost of spending extra to purchase separate nozzles to meet your needs, as is often the case. The nozzles are rated in degrees; from 0 ͦto 15 ͦ nozzles are great for removing mildew and stains from concrete. 25 ͦ to 40 ͦ nozzles can be great for cars while the soap nozzle allows you to apply soap before washing. The versatility of the Simpson and the different nozzles allows you to complete almost any job you can think of effortlessly and quickly.

At 55lbs, the pressure washer is not a lightweight machine. Fortunately, it includes 10-inch pneumatic tires that allow for easy maneuvering to reach wherever you need as you spray. Simpson chose to use rubber wheels so that they’re cushiony and can work well on any surface. The big wheels pair with integrated handles to make transportation and movement a breeze. Plastic tires often make easy movement difficult as they have trouble rolling over uneven surfaces. If you have ever been unfortunate enough to try to move a somewhat piece of heavy equipment with plastic tires, you understand the pain involved. The rubber wheels on the Simpson are greatly appreciated and do well in any environment.

The gas tank holds a large amount of fuel to ensure you are not constantly pausing during cleaning to refill the tank. The components of the MSH3125 are sturdily constructed and put together to give this unit a solid structure. It looks and feels solid and should be able to stand the test of time to offer you long term benefits, provided you engage in regular maintenance to keep it clean and well lubricated. This pressure washer from Simpson comes with hose storage in the back so you can store the machine together with the hose on board without causing a mess or cluttered storage area.

Construction and Ease of Use

If you have been around pressure washers before, you probably understand how much of a problem setting up and using these units can be for novices. However, this is not the case for the Simpson pressure washer. The unit comes fully assembled and ready to use straight out of the box. Thanks to its compact and ergonomic build, it is easy to store the pressure washer when you’re done working. It won’t eat up much space and can be hung from the handles. The handles are comfortable and swapping nozzles is flat-out easy compared to what you would expect.

Build quality is obviously on the higher end with the Simpson MSH3125. The company has used premium quality materials to ensure that the machine keeps up with many years of serious use. A sturdy black steel frame tube and a powder-coated base plate are dedicated to protecting the inner components from damage. The parts are durable, not susceptible to rust, and can withstand normal wear and tear without issue. Maintenance has been made easy with the introduction of the Axial Cam Pump which is a cinch to maintain. The company stands by its product with a 2-year HONDA consumer engine and 1-year limited pump warranty. It also backs the pressure washer with a 5-year limited frame and 90-day accessory warranty.

More Noise than Electric Pressure Washers

Black and white megaphoneThe Simpson MSH3125 gas pressure washer has a few drawbacks that potential buyers should be aware of before purchasing. As this is a gas-powered pressure washer, don’t expect the quiet of an electric pressure washer like the AR383. The powerful engine pumps out a lot of power…and noise. While it may not be “jet engine” loud, it is still noticeable if you have finicky neighbors or a sleeping baby. As it has a very long hose, you can place it further away from potential irritants to help reduce the noise and disturbance.

This pressure washer is also a more expensive unit than what you would expect if you are more used to the price of electric power washers. Gas powered units are usually more expensive than their electric cousins, so it is to be expected. Although it is closer to the mid-range of gas-powered units, don’t expect to see the same prices as the electric models and you won’t be shocked. The additional power offered by units such as the MSH3125 MegaShot more than justify the additional cost if you need more power than an electric washer can provide.

Final Verdict

The Simpson 3200 PSI pressure washer is a step above electric washers in both terms of quality and power. If cleaning power is what you need, then it is hard to beat this level of muscle. As far as powerful performance and ease of use it does well without sacrificing durability or life expectancy. Shop owners and Do-It-Yourself enthusiasts swear by this versatile piece of equipment. Although there are a few issues, overall this is a solid piece of cleaning equipment for mid-range gas pressure washers. While it may not be able to measure up to the more expensive power washers, it took top place in our best affordable pressure washer comparison.
