Powered by a reliable Senci 420CC Heavy Duty OHV gasoline engine that feeds into an AR (Annovi Reverberi) brand Tri-Plex Brass Head Pump, it delivers a powerful 4,200 PSI of cleaning power at 4.0 gallon per minute, that’s over 16,000 Cleaning Units to handle the toughest job

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

The A-iPower APW4200 in use

The A-iPower APW4200

Powered by an impressive 420 cc (14 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 APW4200 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.

The fuel is stored in a tank, which can hold up to 1.7 gallon of gasoline.

Design & Handling

Thanks to its hand truck design and approximate dimensions of D32 x W26.5 x H36 in, the A-iPower APW4200 offers great mobility. The robust steel tubing frame guarantees longevity of the assembly. The handle adds to the APW4200 convenience of transport.

At 132 lbs, we can't really say that the unit is a lightweight, and manually lifting or transporting it could be a challenge. The main contributor to its weight are its 420 cc Senci SC420 engine, the triplex pump and steel tubing frame. However, its two 12" never-flat wheels play an important part in its maneuvrability, as they allow for a smooth manipulation on the job.
