Description
Zoom on the Simpson ALH3228-S
The Simpson ALH3228-S is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- spot cleaning of hard, unpainted surfaces, reaching high areas, and removing stubborn stains
- broad cleaning of hard surfaces, vehicle washing, and surface preparation for painting
- soft cleaning of delicate surfaces, and gentle cleaning for larger areas with low pressure
- applying detergents or chemicals, and rinsing surfaces afterward
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
The Simpson ALH3228-S
Fueled by a 196cc (5.5 hp) engine, its triplex pump can generate a forceful pressure of 3400 PSI (roughly 57 times that of a standard garden hose) and a flow rate of up to 2.5 GPM (CETA-certified values). When these values are taken together, they yield a cleaning power of 8500 Cleaning Units.
To initiate the Honda GX200 engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.
Fuel for the pressure washer is housed in a steel tank capable of holding up to 0.8 gallon of gasoline.
Design & Handling
With its wheelbarrow-inspired design, the Simpson ALH3228-S aims for excellent mobility and stability, enabling effortless maneuvering and dependable performance across diverse environments. Featuring an aluminum frame, this pressure washer boasts easy handling and exceptional durability, thanks to its corrosion-resistant properties and lightweight construction. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
Tipping the scales at 74 lbs, this unit's weight presents a notable challenge for users, especially when it comes to lifting and moving it, particularly over uneven ground. The main contributors to its weight are its 196cc Honda GX200 engine, the triplex pump and aluminum frame. Nevertheless, with its two 10" pneumatic wheels, users can manage the ALH3228-S with less difficulty, even over uneven terrain.
Main Features
The Simpson ALH3228-S
The Simpson ALH3228-S's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: Even without a built-in soap tank, the device relies on a siphon hose to provide detergent. With its automatic soap dilution mechanism, the Simpson ALH3228-S simplifies the process of blending detergent to the prescribed ratio of 7:1. Once a soap nozzle is connected, the pressure washer automatically blends the detergent with the water flow.
- Pressure hose: When not in use, the unit allows for tidy storage of the included 25 ft ⌀5/16" high-pressure hose using a set of convenient hooks, ensuring convenient organization.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its steel wand.
- Nozzles: Review the table below to learn about the 5 included nozzles and the surfaces they're recommended for.

The Simpson ALH3228-S's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the Simpson ALH3228-S compare to similarly priced pressure washers.
- The Simpson ALH3228-S, a device which can produce up to 3400 PSI, is on the lower end of the pressure spectrum, among the gas-powered pressure washers in the $700-800 price range. If the highest possible power of the water stream is your priority, one of the champions in this price range is the Powerhorse 115179 with 4400 PSI.
- In the aforementioned price range, this washer, with 2.5 GPM (gallons per minute), is placed on the lower end of the GPM scale. In case you are looking for a device which can most efficiently rinse away debris in the current price range, the Powerhorse 115179 has the highest GPM of 4.2.
- The ALH3228-S's Cleaning Units, 8500 CU (PSI X GPM), fall into the lower end when compared to gas-powered devices of similar price. If the highest overall cleaning power is a priority, the Powerhorse 115179 and its 18480 Cleaning Units are notable for their higher potential cleaning efficiency compared to units in the same price range.

Simpson makes quality products. It has a Honda engine (like the old Briggs&Straton), which is bullet proof. The CAT Triplex pump is industrial grade. If you use this PW the average of 50hrs per year, it’s a ten year pump. If you take care of the pump, it’ll last much longer or you can use it, like I do, for light commercial use. The frame makes this machine light; I lift it in and out of my truck. Simpson customer service is a little lacking, but you will not call often. I think they are a very small company, that still uses paper and fax machines. I didn’t get all my nozzles; I literally got (4) 0 degree and (1) 15 degree. Called and they quickly apologized and said they send me the other 3 asap. ASAP took about 2 weeks, but I wasn’t in a rush. It’s pricey, but for the money, it competes with PW that run in the $850 to $950 range. Most other PW, in the price range, have either the CAT pump or the Honda or neither.
