Uses of a Pressure washer:
In its extreme high pressure form, water is used in many industrial cleaning applications requiring the removal of surface layers as well as dust-free cutting of some metals and concrete. For exterior applications, gas or propane powered pressure washers provide enhanced mobility not available in electric models, as they do not require use in proximity to an electrical outlet. However, for indoor applications, electric pressure washers produce no exhaust and are much quieter than their gas or propane powered counterparts

The first hot-water high-pressure washer was invented by Alfred Kärcher in 1950. However, Frank Ofeldt in the United States claimed to have invented the steam pressure washer or "high-pressure Jenny" much earlier, in 1927.
