Description
Zoom on the A-iPower PWF4200SH
In summary, the A-iPower PWF4200SH is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, unpainted surfaces or high reach areas
- intense cleaning of tough, paintless surfaces
- cleaning of painted and fragile surfaces
- applying detergent and cleaning solutions
The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.
Power
The A-iPower PWF4200SH
Powered by an impressive 420 cc (13 hp) engine, its brass triplex pump can deliver a pressure of 4200 PSI (around 70 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer). Combined, these values mean that the A-iPower PWF4200SH has a cleaning power of 16800 Cleaning Units.
The Senci SC420 engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.
Gasoline storage is facilitated by a fuel tank with a maximum capacity of 1.7 gallon.
Design & Handling
The wheelbarrow design of the A-iPower PWF4200SH grants mobility and stability to the unit. Its sturdy steel frame provides longevity to the assembly. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
The device weighs 132 lbs and thus, is far from lightweight. Transporting and manually lifting it may therefore pose a challenge. Its 420 cc Senci SC420 engine, the triplex pump and steel frame are mainly responsible for its heavy weight. However, the unit is manipulated smoothly thanks to its two 12" never-flat wheels, which play a key role in its maneuverability.
Main Features
The A-iPower PWF4200SH's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- Pressure hose: A neat storage for the included 50 ft high-pressure hose is facilitated by a set of convenient hooks.
- Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
- Nozzles: The 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
