The Simpson ALH4440-S is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- targeted spot cleaning for hard, unpainted surfaces, reaching elevated areas, and thoroughly removing stubborn stains
- comprehensive cleaning of hard surfaces, vehicle washing, and readying surfaces for painting

Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
With an impressive 420cc engine powering it, the triplex pump of this unit is capable of achieving a pressure of 4400 PSI (approximately 73 times greater than that of a standard garden hose) and a flow rate of up to 4 GPM (values as per PWMA testing standards). Corresponding to these values is a cleaning power of 17600 Cleaning Units.
The CRX 420 engine of this gas-powered pressure washer is initiated by a classic pull-start mechanism.
Fuel for the pressure washer is housed in a tank capable of holding up to 1.6 gallon of gasoline.
Design & Handling
Thanks to its hand truck design and approximate dimensions of L38 x W23.5 x H29 in, the Simpson ALH4440-S offers great mobility. Featuring an aluminum frame, this pressure washer boasts easy handling and exceptional durability, thanks to its corrosion-resistant properties and lightweight construction. The adds to the ALH4440-S convenience of transport.
With its weight clocking in at 133 lbs, this unit's heftiness can't be ignored, presenting significant difficulties for users who need to lift and transport it, especially over uneven terrain. Its 420cc CRX 420 engine, the triplex pump and aluminum frame add up to a large chunk of the device's weight. Nonetheless, the addition of two 13" pneumatic wheels simplifies maneuvering the ALH4440-S, even across rough ground.
Main Features
Along with the Simpson ALH4440-S 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: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. Connection of a soap nozzle triggers the pressure washer to automatically incorporate the detergent into the water stream.
- Pressure hose: With a set of convenient hooks, the unit offers a practical solution for maintaining workspace order, allowing the included 50 ft ⌀3/8" high-pressure hose to be neatly stored when idle.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
- Nozzles: The table below shows you the 5 included nozzles and the surfaces they're the most appropriate for.
