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, 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 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 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 vehicle has tracks above and below the vehicle's windshield. A brush, wiper blade and spray bar extend across the windshield at a starting side of the windshield. The spray bar provides washer fluid as the brush rotates against the windshield. The spray bar, rotating brush and wiper bar are moved along the tracks and across the windshield to an opposing, return side of the windshield where the wiper blade first contacts the windshield and the brush stops rotating and moves away from the windshield. The spray bar rotates next to the wiper blade to blow air against the windshield. The wiper blade scrapes water while air blows water off the windshield as they move back to the starting side of the windshield where they are stored in a frame along the side of the windshield when not in use.

The invention relates to a wiper device comprising at least one wiper strip unit (12a-g) which has at least one first wiper lip (14a-g) and at least one second wiper lip (16a-g). The wiper device (10a-g) has at least one automatically activated wiper lip switching unit (20a-g) which is provided in order to switch a wiper lip (18a-g) that is active in at least one sub-process of a wiping process.

A window washer having a brushing arm mounted to a wiping arm of the window washer, and a motion conversion mechanism for converting back and forth rotational motion of the wiping arm to back and forth linear motion of the brushing arm, thereby the brushing arm rotates with the wiping arm motion, and in addition, linearly slides back and forth from the wiping arm, for brushing a window.

Described is a dual-blade wiper blade for a windshield of a vehicle. The dual-blade wiper blade has a frame structure, a squeegee, a wiping lip, and a scraping lip. The squeegee coupled to the frame structure. Each of the wiping lip and the scraping lip are coupled to the squeegee. The scraping lip being positioned in parallel with the wiping lip.
