Choosing the Right Generac Pressure Washer

Generac offers electric and gas engine pressure washers to match any cleaning task. Consider these factors when picking your Generac model:

Power Source

Electric pressure washers plug into a outlet. Gas models provide onboard power but need refueling. Electric is usually best for homeowners.

Pressure Rating

Measured in PSI, pressure affects cleaning power. 1600-1800 PSI is ideal for home use. Higher PSI tackles tougher commercial jobs.

Flow Rate

The GPM (gallons per minute) rating indicates water volume. 2-3 GPM suits most residential cleaning. Higher flow boosts efficiency on big jobs.


If mobility is important, assess a washer’s weight, handle style, and presence of wheels or a cart.

Special Features

Compare onboard detergent tanks, spray nozzles, hose lengths, warranties, and extra accessories across models.

Generac Pressure Washer Series

SpeedWash: Powerful electric washers for home and auto use.

Genesis: Affordable and reliable gas engine washers.

Heavy Duty: Robust professional-grade gas models.
