A surface treatment machine (10), comprising a frame (11) configured to translate with respect to a surface (12) to treat, a surface treatment element (13) connected to said frame (11) and configured to treat with liquid a surface (12), a reservoir (14) connected to the frame (11) arranged to provide liquid to the surface treatment element (13) through a delivery mouth (15); an adjustment element (16) arranged to feed adjustably the liquid supplied from the reservoir (14) to the delivery mouth (15). It is then provided a sensor (20) adapted to measure the level of residual liquid in the reservoir (14). A control unit (30) receives from the sensor (20) a signal proportional to residual liquid in the reservoir (14) for adjusting the adjustment element (16) responsive to this value, in order to deliver the liquid with optimization of the flow-rate responsive to a liquid saving parameter. It is possible then to maximize the range of the machine, and to optimize the working time of the operator. |
