Many Years of experience have given us the knowledge necessary to build a superior machine for users who need reliable and effective performance even in smaller settings.

You don’t have to sacrifice versatility or performance with the Neptune 4 series. It’s small, but can go more than many larger machines.


The new EcoPower Boiler system developed by Nilfisk-Alto is more than 92% Fuel Efficient, which means you are saving the environment and your money. Because the boiler operates with cleaner combustion, soot build-up is lessened, reducing boiler maintenance and saving fuel costs. That means you have less down time and fewer man hours spent on maintenance.
