Overview
The Simpson Clean Machine CM61083 is a gas pressure washer rated at 3400 PSI and 2.5 GPM, built around a 208cc CRX engine and an axial cam pump, with a 25-foot hose and four quick-connect nozzle tips.
This is a cold-water, homeowner-grade machine rather than a commercial unit, and Simpson notes it is not for sale in California, likely worth checking before ordering there. The low-oil shutdown on the engine and thermal relief valve on the pump both guard against the two most common ways small pressure washers get damaged: running dry on oil and overheating when the trigger sits idle.
- 3400 PSI / 2.5 GPM
- 208cc CRX engine
- OEM Technologies axial cam pump
- 25-foot MorFlex hose
Who it's for
Homeowners cleaning decks, driveways, siding, fencing, and outdoor furniture themselves. Not built for daily commercial cleaning contracts, and not sold in California per the listing.
Pros and cons
- 3400 PSI and 2.5 GPM for faster cleaning
- Maintenance-free pump with thermal relief valve
- Low-oil shutdown protects the engine
- 10-inch pneumatic tires ease transport
- Not compliant for sale in California
- At 64 lb it still takes some effort to maneuver over rough ground
Performance notes
The axial cam pump is described as maintenance-free, so it should not need the periodic oil changes some pumps require, and its thermal relief valve vents heat if the gun sits closed too long so the pump doesn't overheat. Four quick-connect tips, at 0, 15, and 40 degrees plus a soap nozzle, cover jobs from concentrated stripping to gentle rinsing.
