Description

Zoom on the Husqvarna HH42

In a nutshell, the Husqvarna HH42 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, paint-free surfaces and out-of-reach areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and frail surfaces
  • application 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

With a powerful 389 cc engine, its triplex pump delivers a pressure of 4200 PSI (roughly 70 times more than a standard garden hose) and a flow of up to 4 GPM (values as per PW101-2010), resulting in the Husqvarna HH42's cleaning power of 16800 Cleaning Units.

The Honda GX390 engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

The fuel is stored in a tank, which can hold up to 1.6 gallon of gasoline.

Design & Handling

The wheelbarrow design of the Husqvarna HH42 grants mobility and stability to the unit. Its sturdy welded steel frame provides longevity to the assembly. The handle adds to the HH42 convenience of transport.

This model weighs 145 lbs. For this reason, it cannot be called lightweight and thus, carrying and transporting it might be somewhat challenging. Its 389 cc Honda GX390 engine, the triplex pump and welded steel frame are mainly responsible for its heavy weight. However, its two 13" pneumatic wheels play an important part in its maneuverability, as they allow for a smooth manipulation on the job.

Main Features

Along with the Husqvarna HH42 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: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • 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: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: The 5 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

  • Emissions: The Husqvarna HH42 is EPA-approved and CARB-compliant. Thus, selling and purchasing this pressure washer is allowed in each of the 50 states, including California.
