Full review
The Simpson ALH3228-S is a gas-powered pressure washer built for homeowners and professionals who need serious cleaning muscle without sacrificing reliability. Delivering 3200 PSI and 2.8 GPM, this machine tackles tough jobs like stripping old paint, blasting away years of grime from concrete driveways, cleaning siding, degreasing equipment, and prepping surfaces for staining or sealing. At the heart of this unit sits a genuine Honda GX200 commercial-grade engine, known throughout the industry for its dependable starts, smooth operation, and long service life even under demanding daily use.
Simpson didn't cut corners on the pump either, equipping the ALH3228-S with their durable Simpson-brand triplex-style axial cam pump featuring an aluminum head. This construction resists corrosion, dissipates heat efficiently, and keeps the unit running cool during extended cleaning sessions, translating into a longer lifespan compared to pumps made from lesser materials. The washer comes with a 25-foot high-pressure hose that offers ample reach around vehicles, patios, and building exteriors, while the included quick-connect spray tips let users switch between cleaning angles instantly to match the surface and task at hand, from delicate wood decking to stubborn oil stains on garage floors.
Mobility and durability are equally prioritized in the design, with never-flat wheels that roll smoothly over gravel, grass, and uneven terrain without the risk of punctures, plus a rugged frame that protects internal components during transport or accidental drops. The compact, upright design makes storage in a garage or shed simple, and the straightforward pull-start mechanism ensures quick startup even for users less familiar with gas-powered equipment. Backed by Simpson's reputation for building tough, no-nonsense outdoor power equipment, the ALH3228-S stands out as a dependable choice for anyone tackling serious outdoor cleaning projects on a regular basis.

Bought this for cleaning our concrete patio and fence line. The Honda engine fires up on the first or second pull every time, and the pressure is more than enough to strip old paint off wood if I'm not careful. Well worth the investment.
This thing cleans like a beast, no complaints there. My only gripe is that it's heavier than I expected, so moving it up and down our sloped driveway takes some effort even with the big tires.
I run a small detailing side business and this pressure washer has held up great after months of regular use. The triplex pump feels far more solid than the cheaper axial pumps I've used before.
Works excellent as long as you stay on top of oil changes and keep the air filter clean. I underestimated the maintenance side of owning a gas washer, but performance-wise it's outstanding.
