Zoom on the Husqvarna HH42
The Husqvarna HH42, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and frail surfaces
- application of detergent and cleaning solutions
Powered by an impressive 389 cc engine, its triplex pump can deliver a pressure of 4200 PSI (around 70 times more than a standard garden hose) and a flow of up to 4 GPM (values as per PW101-2010). Combined, these values mean that the Husqvarna HH42 has a cleaning power of 16800 Cleaning Units.
This gas-powered pressure washer’s Honda GX390 engine is started by a traditional pull-start mechanism.
Gasoline storage is facilitated by a fuel tank with a maximum capacity of 1.6 gallon.
Design & Handling
The wheelbarrow design of the Husqvarna HH42 grants mobility and stability to the unit. The robust and sturdy welded steel frame offers longevity to the assembly. The handle adds to the HH42 convenience of transport.
With a weight of 145 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. A key role in its final weight is played by its 389 cc Honda GX390 engine, the triplex pump and welded steel frame. However, its two 13" pneumatic wheels play an important part in its maneuvrability, as they allow for a smooth manipulation on the job.
The Husqvarna HH42 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. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
- 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 allows for an easy storage of the included classic ergonomic spray gun and its wand.
