Simpson Cleaning MSH3125 MegaShot
Best OverallPros
- Reliable Honda engine starts easily
- AAA Triplex pump is durable and serviceable
- High 3200 PSI cleans concrete and driveways fast
Cons
- Heavy and not very portable
- Wand could be longer for tall users
The Simpson MSH3125 MegaShot is the most recommended gas pressure washer from the brand in 2021. Owner reviews consistently praise the Honda GC190 engine for its reliable starting and smooth operation. The AAA Triplex plunger pump is a commercial-grade component that outlasts the axial cam pumps found on cheaper units.
This model delivers 3200 PSI at 2.5 GPM, which is sufficient for stripping paint, cleaning heavy grime from driveways, and prepping surfaces for staining. The included spray tips (0, 15, 25, 40 degrees) and a soap nozzle cover most tasks. The main complaint is the weight at 62 pounds, making it less ideal for moving around a large property without a cart.
Simpson Cleaning 60885 PowerShot
Best Budget GasPros
- Good value for the cleaning power
- Lighter than the MegaShot
- Easy to assemble out of the box
Cons
- Engine is louder than Honda models
- Pump is not serviceable
The Simpson 60885 PowerShot is a solid entry-level gas pressure washer for homeowners who need more power than an electric unit but want to save money. It produces 2900 PSI at 2.4 GPM, which is enough to clean fences, patios, and vehicles. The Simpson OHV engine is a reliable budget powerplant, though it does not have the same reputation as the Honda.
Owner reviews note that this model is easier to move around than the MegaShot due to its lighter weight. The included wand and five quick-connect nozzles provide versatility. The main tradeoff is the axial cam pump, which is less durable than the triplex pump on the MSH3125. For occasional use, this is a strong choice.
Simpson Cleaning 60925 PowerShot
Best Light DutyPros
- Lightest gas model in the lineup
- Good for cars, decks, and light cleaning
- Lower price point
Cons
- Not enough power for heavy concrete stains
- Hose is a bit short at 25 feet
The Simpson 60925 PowerShot is designed for lighter tasks around the home. With 2600 PSI and 2.3 GPM, it is suitable for washing cars, cleaning patio furniture, and rinsing decks. It is the lightest Simpson gas washer at 48 pounds, making it easier to carry to different areas.
Owner feedback indicates that this model is quieter than larger units and starts reliably. The axial cam pump is adequate for this power level, but users who plan to clean large concrete areas may find it lacking. The 25-foot hose is also a limitation for larger driveways without an extension.
Simpson Cleaning 61085 PowerShot
Best High FlowPros
- High flow rate for faster cleaning
- Good power for stripping paint
- Includes a turbo nozzle
Cons
- Heavy and bulky
- Engine can be hard to start in cold weather
The Simpson 61085 PowerShot offers a high flow rate of 2.5 GPM at 3100 PSI. This combination allows for faster rinsing and cleaning compared to lower-GPM models. It is a good fit for users who need to clean large areas like long driveways or commercial sidewalks.
Owner reviews highlight the included turbo nozzle as a useful addition for tough grime. The Simpson OHV engine provides adequate power, though some users report cold-start issues. The axial cam pump is a concern for long-term durability, but for regular heavy use, this model performs well.
Simpson Cleaning 60550 PowerShot
Best PortabilityPros
- Compact and easy to store
- Good for small to medium jobs
- Lower noise level than larger models
Cons
- Lower PSI limits heavy use
- Plastic wheel covers feel cheap
The Simpson 60550 PowerShot is the most portable gas model in the 2021 lineup. At 45 pounds, it is easier to lift into a truck bed or carry up stairs. It produces 2700 PSI at 2.3 GPM, which is adequate for cleaning siding, decks, and vehicles.
Owner reviews note that this unit is quieter than larger Simpson models, making it more neighbor-friendly. The compact frame also takes up less garage space. The tradeoff is that the axial pump and lower power mean it is not suited for heavy commercial use or stripping multiple layers of paint.
What to Check Before Buying a Simpson Pressure Washer
Pressure washer shopping can be confusing with PSI and GPM ratings. PSI (pounds per square inch) measures cleaning force, while GPM (gallons per minute) measures water flow. For most home jobs, 2600 to 3200 PSI with 2.3 to 2.5 GPM is the sweet spot. Higher numbers clean faster but use more fuel and water.
Pump type is critical. Simpson uses two main pump types: axial cam pumps (found on PowerShot models) and triplex plunger pumps (found on the MegaShot). Triplex pumps are oil-lubricated, serviceable, and last much longer. Axial pumps are cheaper and lighter but wear out faster. If you plan to use the washer frequently, invest in a triplex pump model.
Engine brand matters. Honda engines are known for reliability and easy starting. Simpson's own OHV engines are decent but can be harder to start in cold weather. Check the warranty: Simpson offers a two-year limited warranty on most models, but the Honda engine has its own separate warranty from Honda.
Mistakes to Avoid
One common mistake is buying a gas pressure washer when an electric model would suffice. If you only need to clean a small patio or car once a month, an electric unit is lighter, quieter, and easier to maintain. Gas washers are better for large driveways, heavy grime, and frequent use.
Another mistake is ignoring the hose length. Most Simpson models come with a 25-foot hose. For large properties, you may need a longer hose or an extension. Also, never use a pressure washer without checking the oil level in the pump (if it is a triplex pump) and the engine.
Finally, do not skip using a pressure washer surface cleaner attachment for concrete. Using just the spray wand can leave streaks and take much longer. Simpson offers compatible surface cleaners that attach to their wands.
FAQs
Are Simpson pressure washers made in the USA?
Simpson is an American brand, but many of their pressure washers are assembled in the USA with global components, including engines from Honda and China.
What is the difference between Simpson MegaShot and PowerShot?
The MegaShot uses a Honda engine and a triplex plunger pump, while the PowerShot uses Simpson's own OHV engine and an axial cam pump. The MegaShot is more durable and expensive.
Can I use a Simpson pressure washer with a water tank?
Yes, but you need a pump that can handle a low-pressure feed. Simpson models with a triplex pump are more tolerant of low water flow than axial pump models.
How long do Simpson pressure washers last?
With proper maintenance, a Simpson with a Honda engine and triplex pump can last 10 years or more. Axial pump models typically last 3 to 5 years with regular use.
What oil does a Simpson pressure washer use?
Simpson recommends SAE 30 or 10W-30 for the engine and SAE 30 non-detergent oil for the triplex pump. Always check the manual for specific requirements.
Is a Simpson pressure washer better than a Karcher?
Simpson gas models are generally more powerful and durable than Karcher gas units. Karcher excels in electric models and accessories. For heavy residential use, Simpson is often preferred.
Can I use bleach in my Simpson pressure washer?
No, bleach can damage the pump seals and internal components. Use only pressure washer-safe detergents and soaps.
How do I winterize my Simpson pressure washer?
Drain the fuel tank and run the engine dry. Use a pump saver or antifreeze designed for pressure washers to protect the pump from freezing.
What size surface cleaner fits a Simpson pressure washer?
Most Simpson models accept a 15-inch or 16-inch surface cleaner with a 1/4-inch quick-connect fitting. Check the GPM rating to match the cleaner's requirements.
Does Simpson offer a warranty on their pressure washers?
Yes, Simpson offers a two-year limited warranty on most models. The Honda engine has a separate three-year warranty from Honda.
Our verdict
For most homeowners, the Simpson Cleaning MSH3125 MegaShot is the best choice for 2021, offering the most reliable engine and pump combination for heavy-duty cleaning. If you need a more budget-friendly gas option, the Simpson Cleaning 60885 PowerShot provides solid performance at a lower cost. Both models deliver the cleaning power that Simpson is known for, but the MegaShot is the clear winner for longevity and performance.
