Nilfisk MH55M Advanced Hot Water Pressure Washer

The Nilfisk MH55M Advanced Hot Water Pressure Washer represents the top tier of Nilfisk’s latest generation hot water pressure washer range, delivering maximum performance, intelligent control, and industry-leading energy efficiency — now backed by an exclusive 2-year warranty*. Designed for heavy-duty industrial and commercial cleaning applications, the MH55M Advanced combines powerful hot water output with advanced operational technology to maximise productivity and reduce operating costs.

At the core of the machine is a newly engineered energy-efficient boiler system, achieving up to 96% fuel efficiency through its innovative internal pre-heating design. By optimising heat transfer within the boiler, the MH55M reduces fuel consumption while maintaining consistent high-temperature performance for the effective removal of grease, oil, heavy contamination, and industrial residues.

The MH55M Advanced is equipped with a smart digital user interface, offering pre-set cleaning programs alongside fully customisable configurations. Operators can lock heating and chemical dosing settings to ensure consistent daily operation and prevent unauthorised adjustments. The display also provides clear visibility of service intervals, maintenance tasks, and fault diagnostics, helping to minimise downtime and streamline machine management.

As part of the Advanced range, the MH55M includes a comprehensive professional specification:

• On-board hose reel for organised storage
• Integrated parking brake for enhanced safety
• Updated flame sensor system for improved boiler reliability
• Integrated chemical dosing system for precise detergent control
• Built-in forklift slots for easy site transport
• Anti-Stone limescale additive tank to protect the boiler in hard water areas
• Steam function for deep, high-temperature cleaning
• Biofuel compatibility for more sustainable operation

For simplified servicing, the MH55M features Bluetooth connectivity for service engineers, enabling rapid diagnostics and efficient maintenance planning.

Available in 230V and 415V variants, the MH55M Advanced is also offered in PA (Pressure Activated) and FA (Flow Activated) configurations:

• PA & PAX models are suitable for all water inlet pressures, offering greater flexibility across varied site conditions.
• FA models require higher inlet water flow and pressure to operate effectively and are designed for environments with sufficient supply capacity.

This flexibility makes the MH55M Advanced ideal for automotive, transport, construction, agriculture, food production, manufacturing, and heavy industrial sectors where robust hot water performance and operational intelligence are critical.
