  • Pressure levels, measured in PSI (pounds per square inch), pascals, or bar, can range from 750 to 30,000 PSI depending on the machine and are adjustable using valves or nozzles.

  • The terms pressure washing and power washing are often used interchangeably, though some distinguish them by whether hot water is used.

  • An industrial surface cleaner uses rotating high-pressure jets to clean flat surfaces evenly and quickly

  • Some surface cleaners have wheeled circular shrouds to protect users from splashback and debris during operation.
