As the ALH3228-S and the ALH3425-S are both Simpson pressure washers, they benefit from the same level of quality and attention to detail.

Power Comparison

  • Fuel: Both units are gas-powered pressure washers.
  • Engine & Pump: The Simpson ALH3228-S and the Simpson ALH3425-S both use a triplex plunger pump to put water under pressure. These 2 pumps are manufactured by CAT and AAA, respectively. In either case, the pump is powered by a 196 cc engine. It is worth noting that both engines are manufactured by Honda. Both devices use a conventional pull-start mechanism to operate.

The following charts are provided to show you at a glance how the main specs of the Simpson ALH3228-S compare to the Simpson ALH3425-S.

  • Pressure: With a maximum reachable pressure of 3600 PSI, the Simpson ALH3425-S provides a somewhat higher force to blast off dirt and grime than the 3400 PSI of the Simpson ALH3228-S.
  • Water Flow: These 2 units offer the same maximum water flow. Each of them should be able to deliver a maximum of 2.5 GPM (gallons per minute) and to offer the same rinsing power.
  • Cleaning Power: With its 9000 C.U., the ALH3425-S offers a somewhat higher overall cleaning efficiency than the Simpson ALH3228-S and its 8500 C.U.

Design Comparison

  • Design: Both units are constructed with a wheelbarrow design. Therefore, if either of these 2 devices should provide better mobility, it would be due to its wheels and weight (which we detail just below).
  • Weight: With an approximate weight of 74 lbs, the ALH3228-S is slightly less heavy than the ALH3425-S (which weighs around 78 lbs).
  • Maneuverability: Both products benefit from a set of wheels, which greatly contributes to their maneuverability. The ALH3228-S has the advantage of having a reversible handle, which allows it to take up less space when not in use.

Feature Comparison

  • Soap Addition: Both washers allow for the addition of chemical detergent solutions to the water. In both cases, this is done via a siphon hose.
  • Trigger Gun & Wand: Each of these 2 units comes with a fairly standard ergonomic trigger gun and a classic wand.
  • Nozzles: Out of the box, the ALH3425-S and the ALH3228-S both come with a 5-nozzle package. The set of included nozzles is the same in either case: 0°, 15°, 25°, 40°, and a soap nozzle.
  • Reach: With its included 35 ft high-pressure hose, the Simpson ALH3425-S will allow you, out of the box, to move farther away from the unit than the Simpson ALH3228-S and its 25 ft high-pressure hose.
  • Storage: The ALH3228-S and ALH3425-S both offer onboard storage that allows you to neatly keep the accessories you need at hand. Both washers feature a set of hooks to help you neatly store their high pressure hoses when not in use.
