Description

The Predator® Commercial Duty Pressure Washer delivers 4400 PSI and 4.2 GPM for unbeatable cleaning power. The professional-grade Annovi Reverberi™ triplex pump has ceramic coated pistons for exceptionally long performance life.

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, paint-free surfaces and out-of-reach areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted or delicate surfaces
  • use of 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 420cc (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.

The Predator engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

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.

This model weighs 133.5 lbs. For this reason, it cannot be called lightweight and thus, carrying and transporting it might be somewhat challenging. Its 420cc Predator engine, the triplex pump and welded steel frame add up to a large chunk of the device's weight. However, the device’s two 12" never-flat wheels play a key role in its maneuverability, as they allow it to be manipulated smoothly.

Main Features

The Predator 4400 in use

The Predator 4400

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: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The detergent is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: A neat storage for the included 50 ft high-pressure hose is facilitated by a set of convenient hooks.
  • Spray gun and wand: A side hook enables you to easily store 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.

    I bought this machine and have not received answers to requests for a specific defective replacement part.

    + PROS: Price, features
    - CONS: Harbor Freight does not answer requests for other than a few scheduled replacement parts. Like their defective cast iron exhaust manifold pipe connecting engine and muffler.
