Pressure washing, hot water and steam suit different professional jobs. Start with the soiling, the surface and the length of each shift rather than a headline pressure rating.
Two equipment families for exterior work
A pressure washer uses water flow and the mechanical action of a jet; heating can help with some oily deposits. An exterior steam cleaning machine adds heat and an adjustable spray. Each method needs a trial on the actual material.
- Pressure washing: compare working flow and pressure together.
- Hot water: check usable temperature, supply and heating system.
- Steam: review hose reach, autonomy and the surface response.
What to provide for a specification
Describe the materials, access, water supply, available power and number of operators. The family pages explain the relevant checks. A particular machine and its supply conditions will only be confirmed after technical review.
