Construction

The construction quality of this machine is of a very high standard. The solid red cart trolley which houses the unit has two large 10" tires which enable the machine to be moved easily for transportation. The tube frame is constructed from 16 gauge steel so it’s incredibly robust and durable.

Powered by the Honda GC190 Engine

At the heart of the Simpson Megashot MSH3125-S is a premium quality Honda GC190 Engine. With a gas operated pressure washer it’s important that it starts first time, every time, this engine does exactly that. It also operates at a low noise level so you don't need to wear ear plugs while blasting away the dirt and grime in your yard.

Using power on-demand technology, the motor is accelerated at its optimum speed when you pull the spray gun trigger then returns back to idle once the trigger has been released. This extends the longevity of the motor and also provides convenience for the user.

A high-performance axial cam pump provides an impressive water flow of 2.5 GPM so you can tackle wider surface areas in little time.

Includes Five Nozzles

Five quick connect nozzles are included which can be quickly connected to the spray wand for maximum convenience. The nozzles give you a variable spray pattern from 0° to 40° so you can get pressure intensity suitable for the surface you are cleaning. A soap applicator nozzle is also included which allows you to apply detergent to a surface area.

Pros and Cons of the Simpson Megashot MSH3125-S Premium Gas Pressure Washer

Pros

The Simpson Megashot MSH3125-S provides excellent power and has a durable construction. Setup is also straightforward so there is no headache in that regard. The motor being Honda is a big advantage, so you can be confident it will start each time you pull the cord.

Cons

The nozzle holders which are situated on the trolley are poorly designed as they don’t hold each nozzle in securely which leads to slight rattling when the machine is in action.

Several consumers found that their machine arrived with a part missing from the box.

In our experience, no gas pressure washer is perfect at this end of the market, but the Simpson Megashot MSH3125-S Premium Gas Pressure Washer is a pretty good machine that is powerful enough for any residential cleaning tasks that you put it to and is very easy to start.
