Simpson ALH3425-S - 3600 PSI 2.5 GPM Gas Pressure Washer With Honda Engine

Power

The Simpson ALH3425-S

With a 196cc (5.5 hp) engine, its triplex pump delivers a pressure of 3600 PSI (roughly 60 times more than a standard garden hose) and a flow of up to 2.5 GPM (CETA-certified values), resulting in the Simpson ALH3425-S's cleaning power of 9000 Cleaning Units.

The Honda GX200 engine of this gas pressure washer is activated by pulling a starter cord, following a traditional approach.

Gasoline is stored in a steel fuel tank with a maximum capacity of 0.83 gallon.

Design & Handling

The Simpson ALH3425-S's wheelbarrow-style design enhances both mobility and stability, enabling seamless navigation and consistent performance, even on rugged terrain. Built with an aluminum frame, this pressure washer prioritizes mobility and longevity, offering corrosion resistance and lightweight design for ease of use and durability. The handle adds to the ALH3425-S convenience of transport.

Tipping the scales at 78 lbs, this unit's weight presents a notable challenge for users, especially when it comes to lifting and moving it, particularly over uneven ground. Its 196cc Honda GX200 engine, the triplex pump and aluminum frame are mainly responsible for its heavy weight. Despite this, the presence of two 10" pneumatic wheels reduces the complexity of moving the ALH3425-S, even on rugged surfaces.

The Simpson ALH3425-S

Along with the Simpson ALH3425-S itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.
