Applications
The Masto M6S is a multifunctional steam cleaner designed for professional cleaning and maintenance of heat pumps, air conditioning systems and other technical equipment. It is particularly suitable for cleaning indoor AC units, where steam and water can help remove dirt and deposits from evaporator coils, blower wheels and other accessible components.
Beyond HVAC maintenance, the M6S can also be used for cleaning ventilation components, kitchen extractor hoods, refrigerators, washing machines and other water- and heat-resistant surfaces. The combination of steam, hot water and cold water makes it a versatile cleaning solution for HVAC technicians, maintenance professionals, facility managers and professional cleaning companies.

Installation & Operation
Connect the machine to a properly grounded electrical outlet with sufficient capacity for the selected operating mode. Fill the water tank with clean water or use the external suction hose to supply water from a separate container. Start the machine in cold water mode to ensure proper water flow before activating the steam or hot water function.
When steam mode is activated, it normally takes approximately 25–30 seconds before steam begins to form. During this warm-up period, residual water in the hoses and internal pipes may be discharged through the nozzle. Point the nozzle towards a bucket, drain or another suitable collection area and wait until a steady steam flow is achieved before starting the cleaning process.
Select the appropriate nozzle and cleaning method according to the application and material. After use, operate the machine in cold water mode to flush out residual hot water according to the manufacturer's instructions.
Important Information
- Electrical supply and circuit protection: The maximum power consumption is 3,300 W, requiring an electrical installation rated for at least 16 A when operating at full power. When connected to a 10 A circuit, the power setting must be limited to a level supported by the available circuit capacity. The 2,200 W steam setting may be used if sufficient capacity is available. Always check the circuit rating and other connected electrical loads before operation.
- Nozzles and water supply: Only use nozzles suitable for the selected operating mode. The 90° angled nozzle and 220° rotating nozzle are intended for hot or cold water operation only and must not be used with steam. Use clean water in steam mode and never operate the machine without an adequate water supply.
- Maintenance and safety: Regularly inspect the inlet water filter and descale the machine when necessary. Hot steam and water may cause burns. Protect sensitive surfaces and electrical components during cleaning.
