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

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 and high-reach cleaning
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted or delicate surfaces
  • application of detergent and cleaning solutions

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

Power

The Predator 4400 in use

The Predator 4400

Its brass triplex pump, which utilizes a powerful 420 cc (13 hp) engine, may deliver a pressure of up to 4400 PSI (almost 73 times more than a standard garden hose) and a flow of up to 4.2 GPM. These values correspond to 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.

A fuel tank with a maximum capacity of 1.45 gallon is used to store gasoline, 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 add up to a large chunk of the device's weight. However, the unit is manipulated smoothly thanks to its two 12" never-flat wheels, which play a key role in its maneuverability.

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. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • 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: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
  • 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.
