Nilfisk was founded in Denmark in 1906 by Peder Andersen Fisker (1875–1975) and Hans Marius Nielsen (1870–1954) as Fisker & Nielsen. Originally the company produced electrical engines as the basic component in ventilators, kitchen elevators, drilling machines and, later on, the Nimbus motorcycle.
In 1989 NKT Holding, listed on the Copenhagen Stock Exchange, bought Fisker & Nielsen. In 1994 Nilfisk A/S acquired Advance Machine Company and in 1998 Nilfisk A/S was renamed Nilfisk-Advance. In 1998 Nilfisk-Advance merged with Euroclean/Kent and between 2000 and 2011, Nilfisk-Advance acquired CFM, Gerni, ALTO, Ecologica, United States Products, Viper, Hydramaster, Egholm, Plataforma and Jungo making Nilfisk-Advance one of the largest suppliers of professional cleaning equipment worldwide. In 2015, Nilfisk-Advance changed name to Nilfisk.
