Zoom on the A-iPower PWF4200SH
The A-iPower PWF4200SH is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- spot cleaning of hard, unpainted surfaces and high-reach cleaning
- thorough cleaning of hard, paint-free surfaces
- cleaning of painted and frail surfaces
- application of detergent and cleaning solutions
Using an impressive 420 cc (13 hp) engine, its brass triplex pump delivers a pressure of up to 4200 PSI (roughly 70 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 16800 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Senci SC420 engine.
A fuel tank with a maximum capacity of 1.7 gallon is used to store gasoline.
Design & Handling
The wheelbarrow design of the A-iPower PWF4200SH grants mobility and stability to the unit. The strong steel frame assures assembly longevity. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
The unit's weight of 132 lbs renders its carrying and transportation challenging, as it is far from lightweight. 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.
The A-iPower PWF4200SH comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The detergent will be added automatically to the water when a soap nozzle is attached.
- Pressure hose: Using a set of convenient hooks, the included 50 ft high-pressure hose can be easily stored on the unit when it is not running.
- Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
- Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.
