Powerhorse 115179 - 4400 PSI 4.2 GPM 420cc Gas Pressure Washer

Power

Utilizing a powerful 420cc engine, this machine's triplex pump can deliver a pressure of 4400 PSI (around 73 times stronger than a standard garden hose) and a flow rate of up to 4.2 GPM (values claimed by the manufacturer). Thus, the Powerhorse 115179 achieves a cleaning power of 18480 Cleaning Units.

For this gas-powered pressure washer, the engine is started using a time-tested pull-start mechanism.

Gasoline is stored in a fuel tank with a maximum capacity of 1.72 gallon.

Design & Handling

With its wheelbarrow design, the Powerhorse 115179 delivers superior maneuverability and stability, facilitating easy transport and steady performance across various surfaces. The durable steel tubing frame of the assembly ensures its longevity, providing stability and shielding internal components from damage, even in tough conditions. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

With its hefty 142 lbs, this unit isn't exactly easy to handle, making manual lifting and transport quite a daunting task, especially on uneven terrain. Its 420cc engine, the triplex pump and steel tubing frame are mainly responsible for its heavy weight. However, the incorporation of two 12" pneumatic wheels makes navigating the 115179 less cumbersome, even on uneven terrain.

Main Features

Along with the Powerhorse 115179 itself, the package also includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are discussed in further detail below.

• Soap injection: The pressure washer features a dedicated tank for detergent storage. Featuring an automatic soap dilution mechanism, the Powerhorse 115179 ensures detergent is mixed to the specified ratio of 15:1 for optimal cleaning results. When a soap nozzle is connected, the pressure washer takes the initiative to mix the detergent with the water flow automatically.
• Pressure hose: The included 50 ft ⌀3/8" high-pressure hose can be neatly stored on the unit when not in use, utilizing a set of convenient hooks for convenient organization.
• Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
• Nozzles: Review the table below to learn about the 4 included nozzles and the surfaces they're recommended for.

Important note: The shapes of the depicted nozzles serve for illustration purposes only and may vary. Symbols used include a red cross for 'Not recommended,' a green check for 'Suitable,' and an orange check for 'Use with caution.'
