As far as water pressure is concerned, both power washing and pressure washing use similar amounts of pressure. How much pressure really just depends on the type of machine; a household unit won’t offer up as much power as an industrial machine.
If we’re talking strictly about the types of machines, there is one key element that differentiates a power washer from a pressure washer: a heating element. Both machines create a powerful stream of high-pressure water, but a power washer also heats up the water. This might seem like a small difference, but it actually makes a huge difference in how each is used.
What is Power Washing?
A power washer uses a high-pressure stream of very hot water to blast away dirt and materials from outdoor surfaces. The combination of high pressure and the temperature of the water make it better at removing all those truly stuck on materials from surfaces. It’s great for removing residue like salt, mildew, and mold from outdoor patios, decks, driveways, and more. The added heat also makes it particularly good at removing things like chewing gum from sidewalks. Power washing is also exceptionally great for handling grease stains on driveways or garage floors.
What is Pressure Washing?
Pressure washing is what you’ve most likely used at your home before. It uses the same high-pressure water blast as power washing but doesn’t use heated water. This regular temperature water still does an amazing job at blasting away dirt but doesn’t perform as well against moss, mold, or other tough stuck-on substances. It still does an amazing job, but might not be able to get rid of tough stains on concrete.
