The Husqvarna HH42 is a gas-powered pressure washer offering a maximum water pressure of 4200 PSI and flow of 4 GPM. (Read full specs)
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
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and fragile surfaces
- applying detergent and cleaning solutions
Its triplex pump, which utilizes a powerful 389 cc engine, may deliver a pressure of up to 4200 PSI (almost 70 times more than a standard garden hose) and a flow of up to 4 GPM. These values correspond to 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 welded steel frame guarantees longevity of 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. The major reasons for its heavy weight are its 389 cc Honda GX390 engine, the triplex pump and welded steel frame. However, the unit is mobile thanks to its two 13" pneumatic wheels, which add to its movability and allow it to be manipulated smoothly 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: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. The detergent will be added automatically to the water when a soap nozzle is attached.
- 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 allows for an easy storage of the included classic ergonomic spray gun and its wand.
