Provided is a multi-chamber reservoir assembly. The assembly comprises a substantially torus-shaped housing defining an interior volume. The interior volume is subdivided with at least two sets of interior walls to define a plurality of fluid chambers. The plurality of fluid chambers are independent and separately operable.

A vehicular cleaning system performs cleaning to remove foreign matter attached to a cleaning target in a vehicle. The vehicular cleaning system includes: an air pump driven to generate an air spray; a washer pump driven to supply a washing solution; a spray nozzle which blows an air-liquid mixed fluid, obtained by mixing the air spray and the washing solution, onto the cleaning target; a washing solution storage unit configured to store the washing solution supplied from the washer pump, and to be capable of discharging the stored washing solution when the washing solution is to be mixed with the air spray; and a mixing and outputting unit configured to blow the air-liquid mixed fluid, obtained by mixing the air spray and the washing solution introduced from the washing solution storage unit, from the spray nozzle toward the cleaning target.

An apparatus includes a sensor lens defining an axis, a first nozzle and a second nozzle positioned a same perpendicular direction from the axis and spaced along a direction parallel to the axis, and an air source fluidly connected to the nozzles. The nozzles are oriented to emit respective airstreams intersecting the axis and directed apart at an acute angle.

An interior windshield wiper apparatus for cleaning the interior of an automobile windshield includes a housing with a pair of wiper apertures extending therethrough. An engagement member is coupled to the housing to selectively engage a dashboard of a vehicle adjacent a windshield. An electric motor is coupled within the housing. A gearbox and a wiper linkage are coupled to the electric motor to drive a pair of wiper arms. The wiper arms are pivotably coupled to the housing and extends through the pair of wiper apertures. A pair of wiper blades is coupled to the pair of wiper arms to clean the windshield of the vehicle as the pair of wiper arms pivots. A wiper button is coupled to the housing to activate the movement of the pair of wiper arms.

A sensor system includes a pump, a valve supplied from the pump, a sensor fixed relative to the pump, a nozzle supplied from the valve and aimed at the sensor, and a computer communicatively coupled to the pump, the valve, and the sensor. The computer is programmed to instruct the pump to operate; while the pump is operating, instruct the valve to close; receive data from the sensor while the pump is operating and the valve is instructed to be closed; and set a flag upon determining, based on the data received from the sensor, that the nozzle is outputting fluid onto the sensor.

A sensor apparatus includes a cylindrical sensor window defining an axis and a ring fixed relative to the sensor window and centered around the axis. The ring includes a liquid chamber, at least one nozzle, and an air chamber. The liquid chamber is elongated circumferentially around the axis. The at least one nozzle is fluidly connected to the liquid chamber and has a direction of discharge aimed at the sensor window. The air chamber is elongated circumferentially around the axis alongside the liquid chamber. The air chamber lacks inlets and outlets.
