Zoom on the Predator 4400

In a nutshell, the Predator 4400 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, unpainted surfaces or high reach areas
  • intense cleaning of hard, unpainted 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 Predator 4400 in use

The Predator 4400

Using an impressive 420 cc (13 hp) engine, its brass triplex pump delivers a pressure of up to 4400 PSI (roughly 73 times more than a standard garden hose) and a flow of up to 4.2 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 18480 Cleaning Units.

This gas-powered pressure washer’s Predator engine is started by a traditional 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. The strong welded steel frame assures assembly longevity. The handle adds to the 4400 convenience of transport.

The device weighs 133.5 lbs and thus, is far from lightweight. Transporting and manually lifting it may therefore pose a challenge. Its 420 cc Predator engine, the triplex pump and welded steel frame are mainly responsible for its heavy weight. However, the device’s two 12" never-flat wheels play a key role in its maneuvrability, as they allow it to be manipulated smoothly.

Main Features

The Predator 4400

Along with the Predator 4400 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail 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: The 50 ft high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using 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 table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.
