Further down the page, you'll find some explanations regarding the key similarities and differences between the Simpson MSH3125-S and the Simpson MS60921-S.
But before checking out explanations regarding their power, design, and features here's a table that summarizes the main pros of each of these 2 pressure washers:

Power Comparison
- Fuel: Both units are gas-powered pressure washers.
- Engine & Pump: The Simpson MSH3125-S and the Simpson MS60921-S both use an axial-type pump to put water under pressure. In either case, the pump is powered by a 187cc 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 MSH3125-S compare to the Simpson MS60921-S.
- Pressure: With very similar maximum reachable pressures (3200 PSI for the Simpson MSH3125-S and 3300 PSI for the Simpson MS60921-S), both devices should do an equally good job at lifting and blasting off dirt.
- Water Flow: When operating at low pressure, the MSH3125-S can generate a slightly higher maximum volume of water than the MS60921-S. It can deliver up to 2.5 GPM (gallons per minute), whereas the MS60921-S offers a maximum water flow of 2.4 GPM. The former should thus allow you to rinse away dirt and debris with somewhat better efficiency and speed.
- Cleaning Power: As the difference in Cleaning Units between the Simpson MSH3125-S and the MS60921-S (8000 and 7920 C.U., respectively) can be considered negligible, we can say that both these devices share the same overall cleaning efficiency.
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: Weighing 55 lbs, the MSH3125-S is far lighter than the 71 lbs of the MS60921-S.
- Maneuverability: Both products benefit from a set of wheels, which greatly contributes to their maneuverability. Both offer a handle, which improves your grip when you wish to move them.
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 MS60921-S and the MSH3125-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: Both products include a 25 ft high-pressure hose. Therefore, neither of them will, out of the box, allow for a higher freedom of movement around the unit.
- Storage: The MSH3125-S and MS60921-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.
