A surface wiper device which includes a carrier which supports a blade. The carrier attaches to a wiper arm which urges the blade against and moves the blade across the surface of a windshield. The carrier further provides a plurality of outlets each of which communicate between a hollow passage inside the carrier and a location on the external surface of the carrier. A fluid can be delivered from a fluid source fluidicly coupled to the hollow passage of the carrier under sufficient pressure to be dispersed from the plurality of outlets onto the windshield during movement of the blade. A fluid heater can be thermally coupled with the fluid delivered from the fluid source to the plurality of outlets to increase the temperature of the fluid dispersed onto the windshield. The fluid can be sufficiently heated to generate a heated gas.

A vehicular windshield wiper control system includes a camera disposed at a vehicle and viewing through a windshield of the vehicle and an electronic control unit (ECU). Electronic circuitry of the ECU includes an image processor. The system, based on processing of image data captured by the camera, is operable to determine presence of a substance at an outer surface of the windshield. The system includes a windshield wiper having a rubber wiping blade and a cleaning element. The system is operable to (i) cause the rubber wiping blade to engage the windshield and/or (ii) cause the cleaning element to engage the windshield. Responsive to determining presence of the substance, the system causes the cleaning element to engage the windshield. With the rubber wiping blade and/or cleaning element engaging the outer surface of the windshield, the system moves the rubber wiping blade and/or cleaning element along the windshield.

Disclosed is an optical window cleaning device, including: a cleaning brush; and a wiper arm. The wiper arm includes a first link, a torsion mechanism, a second link and a wiper arm drive system. A second end of the first link is hinged to a first end of the second link. The cleaning brush is hinged to a first end of the first link, a rotation trajectory of the cleaning brush and a rotation trajectory of a hinge joint between the second end of the first link and the first end of the second link are both located in a first plane. A rotation trajectory of the second link and the rotation trajectory of the hinge joint are located in the first plane. The torsion mechanism provides the first link and the second link with a force that rotates the first link relative to the second link.

A LiDAR sensor may include: a housing; a window cover installed on the housing; a motor mounted in the housing; a rotating shaft rotated by the motor; a guide connected to the rotating shaft and rotated along the surface of the window cover; and a brush mounted on the guide so as to face the window cover, contacted with the window cover, and washing the surface of the window cover with rotation of the guide. The guide may include: a first guide part connected to the rotating shaft; a second guide part rotatably connected to the housing; and a third guide part connected to the first and second guide parts, formed in a U-shape so as to face the window cover, and having the brush mounted thereon.

A cleaning device for a surface, such as a windshield of a vehicle, has a housing that holds a spray bar, rotatable brush and a wiper blade. An engagement mechanism moves spray bar, the brush, and the wiper blade out from a disengaged position within the housing to an engaged position outside the housing so that they can be used to clean, brush, and dry the surface. After the spray bar, brush, and wiper blade are used to, respectively, clean, brush, and dry the surface, the engagement mechanism then moves the spray bar, the brush, and the wiper blade to a disengaged position within the housing.

A cleaning device for a surface, such as a windshield of a vehicle, includes an active positioning system and a cleaning head. The active positioning system is configured to deploy from a storage position hidden from view within a covered storage space and to position the cleaning head upon the windshield. The active positioning system includes a first extension member and a second extension member that move relative to one another to position the cleaning head, and also move the cleaning head across the windshield along a path. The cleaning head can have a brush portion configured to agitate debris from the window, and a drying portion configured to dry the window after cleaning. The cleaning device can be controlled via a touch-screen display in the vehicle, enabling a user to direct that specific portions of the windshield be cleaned as desired.

A brushing system, including: a brush; and a hydraulic motor, for rotating the brush. The hydraulic motor is operable by pressurized water, and the pressurized water is administrable by outlets of the brush, thereby brushing of the brush is accompanied by the administrable water.
