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, paintless surfaces and reaching far-away areas
- thorough cleaning of hard, paint-free surfaces
- cleaning of painted or delicate surfaces
- applying detergent and cleaning solutions
Powered by a powerful 420 cc (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 storage is facilitated by 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. The robust and sturdy welded steel frame offers longevity to the assembly. The handle adds to the 4400 convenience of transport.
The unit's weight of 133.5 lbs renders its carrying and transportation challenging, as it is far from lightweight. Its 420 cc Predator engine, the triplex pump and welded 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 maneuvrability.
The Predator 4400 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. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
- 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 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
