Long known for its portable generator design, Generac introduces its lineup of commercial-grade pressure washers, enabling you to power wash your deck, prep for painting, remove tough concrete stains, and more at home and on the job site. The Generac 5993 provides 3,100 PSI of power and 2.8 gallons per minute (GPM) for a cleaning power rating of 8400.
It's powered by a Generac overhead valve (OHV) horizontal-shaft engine, the largest available for its respective pressure rating. Generac OHV engines come standard with low-oil shutdown to protect and prolong the life of the engine. Both the engine and pump are perfectly balanced over the axle and wheels for almost effortless maneuverability, regardless of terrain. Generac pro models also offer durable, welded roll-cage style frames that protect both the engine and pump from damage.
It comes with an ergonomically designed professional-grade spray gun, which features a unique cushion grip that reduces fatigue by minimizing vibration. The innovative easy-to-pull spray trigger can be held with a minimum of effort, and the Quick-Click nozzle tips are easy to replace. Additionally, this pressure washer's gun comes with an adjustable side handle for additional comfort and control when cleaning up high, down low, or anywhere in between.
This power washer is backed by a three-year limited warranty.
Note for California residents: This model is not CARB-compliant. Units sold to California must be CARB-compliant.
What Is PSI and GPM?
Short for "pounds per square inch," PSI is a measure of the water pressure coming out of the power washer. A typical garden hose dispenses water at about 30-40 PSI, and a coin-operated car wash provides about 700 PSI. A power washer, by contrast, typically dispenses water at several thousand PSI. Another important factor in power washers is GPM, which stands for "gallons per minute" and describes how much water is flowing through the pressure washer.
Together, they provide your power washer's cleaning power. Multiply PSI (which gives you the power to lift dirt and grime) by GPM (which provides the necessary quantity of water to wash it away) to get the cleaning power rating. The higher the number, the greater the cleaning power.
Here are some application examples with how much cleaning power (PSI and GPM) you'll need to get the job done.
