Pressure Washing 101

How Pressure Washers Work

Pressure washers work by aggressively blasting things clean with pressurized water jets. Pressure washers can operate at up to 75 times the pressure of a standard garden hose. Pressure washers are typically rated using Pounds per Square Inch (PSI) and Gallons Per Minute (GPM).

Gas? Electric? What’s the Difference?

Lighter duty pressure washers can run off of your power supply; these units are quieter, more compact, and much easier to move around. More powerful models use gasoline engines. Gas engines are preferred for users who will be working outside where it may be difficult to find an electric supply, or when using extension cords would be dangerous.

A pressure washer is like a garden hose combined with an air compressor. Either an electrical motor, or a gas-fueled engine power a water pump. That water pump speeds up the water, feeding in from a garden hose connected at one end. At the other end is a high pressure hose, with a water gun (similar to the water guns you would see in a car wash!). Pull the trigger, and water and air mix and are forced out the nozzle.

Pressure Washer Terminology

When choosing a pressure washer, you’ll see the same 2 numbers referenced regularly: PSI and GPM. Overall, higher numbers mean faster cleaning. But remember! Faster isn’t always better. Using pressure too high for the surface you’re cleaning could leave you with irreparable damage.

Pounds per Square Inch (PSI): Pounds per Square Inch, most commonly referred to as PSI, refers to the water pressure measured at output.
Gallons per Minute (GPM): GPM is the measure of water flow delivered to the spray gun.

Pressure Washer Power: Engines

Your pressure washer’s engine is one of the most integral parts, playing a pivotal role in performance and reliability. The engine can make or break your pressure washing experience. All of Vortexx’s gas power pressure washers are powered by Honda engines, guaranteed to be easy to start, efficient, reliable, and provide you with a quiet, smooth performance.
