Detailed Description
The Simpson 3500 PSI gas pressure washer is designed as a 2.5 GPM residential power washer to offer strong cleaning performance without the complexity of commercial units. PowerBoost Technology provides more impact at the nozzle for stubborn dirt. The Kohler SH270 engine includes low-oil shutdown to protect the motor, and the AAA AX300 Pro Axial pump requires minimal maintenance — a big plus for homeowners who want a low-maintenance gas pressure washer.

The included 25 ft pressure washer hose gives plenty of reach for most residential jobs, and the five quick-connect tips let you switch from heavy-duty driveway work to delicate car or siding cleaning quickly.
