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.

Consider that the average pressure washing costs between $192 and $401 per job. If you did two jobs a day at $250 each, you'd make $130,000 a year working 260 days per year. That's good money and a lot of time off to enjoy it. In this guide, we'll walk you through how to start a pressure washing business.

A power washing machine's jet wash uses heated water, while a pressure washer uses cold water. Both techniques use water pressure to remove dirt, grime, algae, etc., from outdoor surfaces. However, power washing also heats water to clean hard to remove dirt.
