Abstract: Example embodiments relate to wiper devices for cleaning sensor housings. An example embodiment includes a wiper device for cleaning a surface of a rotatable sensor housing. The wiper device may have a driving arm having a first end and a second end. The first end of the driving arm is connected to a rotatable shaft. The wiper device may also have a wiper arm pivotally connected to the second end of the driving arm. The pivotal connection is located between a front region and a rear region of the wiper arm. Further, the wiper device may have a wiper blade coupled to the front region of the wiper arm. The wiper blade may be configured to wipe the surface of the rotatable sensor housing. Additionally, the wiper device may have a counterweight coupled to the rear region of the wiper arm.
