Simpson MegaShot MSH3125-S (3200 PSI Gas, Honda GC190)
Top Pick9.6/10Editor’s score
Best for large or heavily stained driveways
- Honda GC190 engine is known for easy starts and long service life
- 3200 PSI / 2.4 GPM cuts through baked-on grime and oil stains faster than electric models
- Onboard detergent tank makes pre-soaking stains straightforward
Watch out Gas power means oil changes, fuel stabilizer for off-season storage, and more noise than an electric unit
