Deciding On a Gas or Electric Powered Pressure Washer

Gas-powered pressure washers are more mobile and can provide higher pressures and flows then electric Pressure Washers. Because the washer produces carbon monoxide from the gasoline, it may only be used outdoors..

Electric pressure washers are good for indoor work and projects close to an electric source. They are limited in overall power but can be used indoors or outdoors and are quieter than gas-powered washers.

Deciding on a Hot or Cold Water Pressure Washer

Hot water pressure washers clean faster and more thoroughly than cold water pressure washers. They use less soap to sanitize and degrease, making them ideal for industrial and farm use.

Cold water pressure washers are less complicated and are more compact for easy portability.
