One kind having the water-driven assembly of devices of float function, mainly includes: a water-driven device and at least a buoyant member. The water-driven device is equipped at least one first engaging portion. An at least buoyant member has one second engaging portion, and at least one first engaging portion of the water-driven device is corresponding with second engaging portion of an at least buoyant member to be combined. Thereby, the buoyancy which provides enables the water-driven device to float the what water surface, and need not fix with a sink, with the use of the sharp water-driven device.一種具有漂浮功能之水驅動裝置總成，主要包含有：一水驅動裝置以及至少一漂浮件。該水驅動裝置設有至少一第一結合部。該至少一漂浮件具有一第二結合部，該水驅動裝置之該至少一第一結合部與該至少一漂浮件的該第二結合部對應結合。藉此，該二漂浮件所提供之浮力，使該水驅動裝置能夠漂浮於水面，而無須與一水槽固定，以利該水驅動裝置之使用。
