Description
Zoom on the Powerhorse 115178
The Powerhorse 115178, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- comprehensive cleaning of hard surfaces, vehicle washing, and readying surfaces for painting
- gentle cleaning of delicate surfaces, and low pressure cleaning of larger areas
- using cleaning solutions, and rinsing surfaces to remove residue
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
Fueled by a powerful 274cc engine, its triplex pump can generate a forceful pressure of 3800 PSI (roughly 63 times that of a standard garden hose) and a flow rate of up to 3.6 GPM (values claimed by the manufacturer). When these values are taken together, they yield a cleaning power of 13680 Cleaning Units.
To initiate the engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.
The pressure washer's tank has a maximum capacity of 1.32 gallon for storing gasoline.
Design & Handling
The Powerhorse 115178's wheelbarrow-style design enhances both mobility and stability, enabling seamless navigation and consistent performance, even on rugged terrain. Built to endure, the steel tubing frame ensures the assembly's longevity by providing stability and safeguarding internal components under all working conditions. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
At 120 lbs, this unit's substantial weight makes it quite a challenge for users to lift and maneuver, particularly on uneven surfaces where its heft can become even more apparent. Its 274cc engine, the triplex pump and steel tubing frame add up to a large chunk of the device's weight. Despite this, the presence of two 10" pneumatic wheels reduces the complexity of moving the 115178, even on rugged surfaces.
Main Features
The Powerhorse 115178 comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: Detergent storage is ensured by a dedicated tank. The Powerhorse 115178 includes an automatic soap dilution mechanism, allowing detergent to be diluted to the ratio of 15:1 with ease. The detergent is automatically mixed with the water flow by the pressure washer when a soap nozzle is connected.
- Pressure hose: The unit comes equipped with an included 35 ft ⌀3/8" high-pressure hose, which can be neatly stored on the unit when idle, thanks to a set of convenient hooks, ensuring easy access and organization.
- Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
- Nozzles: The following table provides information on the 4 included nozzles and their recommended surface uses.
15° | 25° | 40° | Soap | |
|---|---|---|---|---|
| Concrete, brick, masonry | ||||
| Siding, gutters, house | ||||
| Fencing, deck, patio | ||||
| Lawn equipment, boat, RV |
