A controller connects to the circuit and illuminates a visual indicator as a relative function of the cleanliness or dirtiness of a signal of a dirt sensor connected to the controller. A motor is also controlled by the controller as a relative function of the dirt sensor signal. Further, the flexible membrane circuit includes a side opposite the adhesive side to friction fit the visual indicator against the housing. Preferably, the visual indicator includes a plurality of colors, from light emitting diodes, wherein the side opposite the adhesive side of the circuit connects to the light emitting diodes.
