Some one knows what kind of sensor is this and how it works? Is from a vacuum robot. I guess to check something on floor. I would like to connect it to Arduino.

That appears to be some sort of fluorescent lamp. Note that the wires to the connector are labeled IN+ and IN-, and the wires to the lamp OUT+ and OUT-. That doesn't make sense for a sensor. The transformer also hints at high voltage being made, as would be required for such a lamp.

It might be a germicidal UV lamp. Those are a form of fluorescent lamp, but their function isn't available from LEDs. That would also explain the apparent lack of phosphor coating the inside of the bulb.
