Industrial Steam Cleaner – Nilfisk SO4500 Steam Cleaning Machine | Heavy Duty Industrial Steamer

The Nilfisk SO4500 is a compact, durable and highly effective industrial steam cleaner designed for medium-duty commercial cleaning where steam-only cleaning is required. With 4.5 Bar steam pressure, 150°C steam temperature, and a continuous-fill boiler, it delivers powerful sanitising performance for schools, workshops, factories, leisure facilities and general commercial environments.

Because this is a steam-only machine (no vacuum, no detergent injection), the SO4500 is extremely simple to operate and maintain. Surfaces can be left to air-dry or wiped down with a cloth, making it ideal for users who want maximum reliability without extra systems.

Despite its compact 12kg body, the SO4500 produces professional-grade dry steam capable of breaking down grease, killing bacteria and sanitising surfaces throughout the day.

Why Choose the Nilfisk SO4500 Steam Cleaner?

Continuous Fill Boiler – No Downtime

Its continuous-fill design allows you to top up the 5L water tank at any time without shutting the machine down or waiting for pressure to rebuild — perfect for longer cleaning sessions.

• Easier to maintain

• Highly reliable for daily cleaning
• Ideal for environments where chemical-free cleaning is preferred

Need Higher Temperature, Larger Tanks, Longer Hose & More Power?

If you require hotter steam (up to 165°C), a bigger water tank, a larger vacuum drum, a higher-pressure system, and a longer hose for extended reach, take a look at the Nilfisk SDV8000 — the upgraded heavy-duty model designed for full industrial cleaning workloads.
