IEC 60335-2-68:2021 deals with the safety of electrical portable, non-self-propelled motor-operated spray extraction machines with or without attachments and with or without electrical heating elements, intended for commercial indoor use. This standard applies to machines for commercial use. The following list, although not comprehensive, gives an indication of locations that are included in the scope:

They are not equipped with a traction drive. The following power systems are covered: mains powered motors up to a rated voltage of 250 V for single-phase appliances and 480 V for other appliances and battery powered motors. This standard applies to machines in which the pressure of the employed cleaning agent does not exceed 2,5 MPa, and in which the product of the pressure (in MPa) and the flow of cleaning agent (in litres per minute) does not exceed 100, and in which the temperature of the cleaning agent at the spray nozzle outlet does not exceed 85 °C.
