Apparatus for cleaning a window of a vehicle, comprising:
- a vessel, having an inlet through which a washing fluid is received from a reservoir and an outlet through which the fluid is discharged for cleaning the window;
- a heating element for heat the fluid in the vessel;
- a temperature sensor, which senses a range of temperatures in the vessel;
- and
- a valve for controlling flow of the fluid through the vessel;
- characterized by said valve being in electrical communication with said temperature sensor, said valve automatically and intermittently releasing quantities of the fluid through the outlet at a desired temperature, in response to the temperate sensed by the sensor.
