Power and pressure washing both involve spraying water with high pressure to clean surfaces. Although they are similar in function, their process for washing varies.
The main difference between the two is that power washing uses hear in tandem with water pressure to clean surfaces.
Power washing used high-pressured steam to wash surfaces while pressure washing uses high-pressured cold water to get rid of dirt and other debris.
Pressure washing is a better option for residential siding, patio, decks, driveways, garages and more. Meanwhile, power washing is better suited for heavy-duty commercial jobs. Heated water is more effective for cleaning the tougher surfaces found in commercial properties.
