The main difference is that power washing uses highly pressurized steam to do the cleaning while pressure washing just uses unheated tap water, without the help of a heating element.

Pressure washing goes by many other names such as jet washing. This type of equipment is a cleaner that forces a high-pressure stream of water through a nozzle.

Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces.

Instead of relying on high pressure to blast away dirt and grime, soft washing uses a combination of low-pressure power washing and cleaning solutions to clean surfaces. These solutions settle in the layers of dirt, eating them away from the inside. The cleaners then use low-pressure power washers to rinse the surface.
