Wiper, cleaning system, sensor, and vehicle

A sensor, sensor rotating around a rotating axis, and comprising:

• a sensor body, with a surface to be clean;
• and
• a wiper, to clean the surface to be clean, and comprising:
• a counterweight slider;
• a sliding assembly, with a wiper arm configured to slide with the sliding assembly to clean the surface to be clean, and
• a transmission mechanism;
• wherein the counterweight slider and the sliding assembly are slidably coupled to the transmission mechanism, and are driven to slide at the same speed but in opposite directions by the transmission mechanism;
• and the counterweight slider and the sliding assembly have equal COM, ensuring a combined COM of the counterweight slider and the sliding assembly remain at a position when the wiper arm in both motion and stopped states.

A vehicle, wherein the vehicle includes:

• a vehicle body;
• and
• a sensor, mounted on the vehicle;
• the
