Critical function prototyping (CFP) is useful when developing product service systems. Focusing on testing the critical component of the system first, as opposed to the whole system, saves resources that can be used elsewhere. This paper exemplifies CFP applied to a drone-based cleaning system, where the cleaning process is considered the critical function. Three CFPs were built and tested to find the most promising design. The best design was then tested to further explore the feasibility of the critical function. The method enabled us to test fast, decreasing the risk while saving resources.
