The SIMPSON 65215 SuperPro Roll-Cage is a 7,000 PSI cold-water gas pressure washer built for the toughest commercial and industrial cleaning. With 7,000 PSI at 4.0 GPM, a Kohler CH750 engine, and a gear-drive COMET triplex plunger pump, it is engineered for crews that strip, prep, and clean heavy surfaces where standard 3,000-to-4,000 PSI machines fall short.
Built for heavy industrial cleaning
This is a high-output machine for demanding professional jobs:
- Industrial paint and coating removal on metal and concrete
- Surface preparation before recoating, lining, or sealing
- Heavy equipment, fleet, and structural steel cleaning
- Concrete and masonry restoration where extreme pressure speeds the work
At 7,000 PSI, this machine demands proper training, the correct nozzles, and full protective equipment. It is a professional tool intended for experienced operators, not general-purpose cleaning.
Industrial power and a gear-drive pump
The Kohler CH750 engine includes a low-oil shutdown feature to help protect the engine. The COMET industrial triplex plunger pump uses a gear drive for high-pressure output and long service life, and a remote unloader with bypass hose adds industrial durability for extended pump life. The 3/8-inch by 50-foot wrapped rubber hose is rated up to 8,000 PSI with a 250 degree Fahrenheit maximum temperature.
Built to move and stay stable
A heavy-duty four-wheel cart with wheel-locking brakes sits on a large steel frame with sub-frame construction, and 13-inch premium pneumatic tires roll over rough job sites. The locking brakes keep the unit planted during high-pressure operation.

Frequently asked questions
Who is a 7,000 PSI machine for?
It is for trained professionals doing industrial surface prep, coating removal, and heavy cleaning. At this pressure, proper nozzles, technique, and protective gear are essential, so it is not intended for general homeowner use.
Why a gear-drive pump?
Gear drive lets the COMET triplex pump run at the speed needed for sustained high-pressure output while reducing stress on the pump, which supports longer service life under heavy use.
What does the remote unloader add?
The remote unloader with bypass hose manages pressure when the trigger is released and routes bypass water to protect the pump, adding industrial durability and extending pump life.
Is the hose rated for this pressure?
Yes. The 3/8-inch by 50-foot wrapped rubber hose is rated up to 8,000 PSI with a 250 degree Fahrenheit maximum, giving margin above the machine's 7,000 PSI output.
