Italian to English Other Other Cleaning

I'm translating a piece on an "idropulitrice" (translated by the client as "high pressure washer") which can be transformed into an "idrooperatore" with the addition of a certain accessory. This basically means that it can be used for a wider range of applications, such as washing and waxing cars, in wine making for sanitising casks, for cleaning cattle stalls, etc. Can anyone suggest how I might translate that "idrooperatore"? Many thanks, Sarah.
