Simpson MSH3125-S review

Simpson MSH3125-S Power Cleaner

Simpson 3100 psi pressure washer is easy to move around due to its 10-inch pneumatic tires. You can clean your backyard with great ease due to its lightweight structure, roughly 65 pounds.

This heavy-duty power cleaner has a horizontal orientation design which makes it more reliable and easy-to-use. Even with this structure, it carrier the not-so-famous-not-so-durable axial cam pump.

It has a downstream injection system which increases its complexity. The siphon hose that it uses doesn’t have the detergent in an onboard tank which makes it a bit difficult to apply it.

Since this machine has lots of power in its storage, you will have to be careful about handling it.

Guess what?

The cleaning power rating on the Honda powered pressure washer is a colossal 7750 which makes enhances its authenticity for power-based cleaning. It has 3100 PSI and 2.5 GPM plus patented Power Boost Technology that can provide you with an extensively high pressure at the nozzle.

Let us have a look at the pros and cons of the Simpson MSH3125 3100.

  • Huge Size – Due to the powerful motor it houses, Simpson pressure washer is a huge machine with the overall dimensions – 33 inches x 21 inches x 19 inches. You might have to be ready to prepare some room for this.
