IEC 60335-2-79:2021 deals with the safety of high-pressure cleaners without traction drive, intended for household and commercial indoor or outdoor use, having a rated pressure not less than 2,5 MPa and not exceeding 35 MPa. It also applies to steam cleaners and those parts of hot water high pressure cleaners incorporating a steam stage which have a capacity not exceeding 100 l, a rated pressure not exceeding 2,5 MPa and a product of capacity and rated pressure not exceeding 5 MPa·l. They are not equipped with a traction drive. The following power systems of the drive for the high pressure pump are covered:

- mains powered motors up to a rated voltage of 250 V for single-phase machines and 480 V for other machines,

- battery-operated motors,

- internal combustion engines,

- hydraulic or pneumatic motors.

This standard does not apply to:

- high pressure water jet machines having a rated pressure exceeding 35 MPa;

- liquid or steam cleaners intended for domestic use (IEC 60335-2-54);

- hand-held and transportable motor-operated electric tools (IEC 60745 series, IEC 61029 series, IEC 62841 series);

- appliances for medical purposes (IEC 60601);

- agricultural sprayers (ISO 4254-6);

- non-liquid, solid abrasive cleaners;

- machines designed to be part of a production process;

- machines designed for use in corrosive or explosive environments (dust, vapour or gas);

- machines designed for use in vehicles or on board of ships or aircraft.
