Description
Zoom on the Predator 4400
The Predator 4400 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
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and fragile surfaces
- applying detergent and cleaning solutions
Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
The Predator 4400
Powered by an impressive 420cc (13 hp) engine, its brass triplex pump can deliver a pressure of 4400 PSI (around 73 times more than a standard garden hose) and a flow of up to 4.2 GPM (values claimed by the manufacturer). Combined, these values mean that the Predator 4400 has a cleaning power of 18480 Cleaning Units.
The Predator engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.
Gasoline is stored in a fuel tank with a maximum capacity of 1.45 gallon, which provides an approximate runtime of 120 minutes.
Design & Handling
The wheelbarrow design of the Predator 4400 grants mobility and stability to the unit. Its sturdy welded steel frame provides longevity to the assembly. The handle adds to the 4400 convenience of transport.
With a weight of 133.5 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. Its 420cc Predator engine, the triplex pump and welded steel frame are mainly responsible for its heavy weight. However, its two 12" never-flat wheels play an important part in its maneuverability, as they allow for a smooth manipulation on the job.
