Tesla has confirmed that it is working on a “comprehensive cleaning solution” for its vehicles’ onboard cameras. The confirmation was made on X, where the official Tesla AI account was responding to a post highlighting how quickly the rear camera on the Cybertruck can become obscured by dirt, particularly in off-road or wet conditions.
However, Tesla has not clarified whether the solution will be exclusive to the Cybertruck or extended to other models in its lineup. It also remains unknown whether existing vehicles will be able to receive the upgrade as a retrofit.
On a more serious note, a more comprehensive cleaning solution is being worked on

Tesla’s vehicles rely heavily on cameras for Autopilot and Full Self-Driving (FSD) functionality, using an array of external cameras to provide a near 360-degree view of the vehicle’s surroundings. While this camera-based approach eliminates the need for radar or LiDAR, it also presents a significant challenge when these cameras get covered in dirt, snow, or road grime.
Winter conditions, in particular, pose a problem for Tesla’s camera system. Snow, slush, and ice can accumulate on the lenses, especially in areas where road salt is commonly used. Even in non-winter conditions, dust, mud, and rain streaks can impair visibility, reducing the accuracy of FSD features and forcing drivers to manually clean the cameras.
If one or more cameras become obstructed, the system may not function optimally, leading to reduced performance or even disengagement of FSD features.
Tesla has not disclosed details about the upcoming cleaning system, but there are several potential approaches the company could take. Some possibilities include:
- Automated Spray System: Similar to headlight washer on the Cybertruck’s front camera, a small nozzle could spray washer fluid onto camera lenses when needed.
- Hydrophobic Coatings: Hydrophobic coatings could be applied to camera lenses to repel water and dirt.
- Pressurized Air: Pressurized air could be used to blow away dust and moisture from lenses.
Tesla’s statement suggests that the company is taking the issue seriously, but it remains to be seen how soon a solution will be implemented and whether it will be limited to new models or made available as a retrofit for existing vehicles.
Tesla has already partially acknowledged this issue, launching the first camera washer for the Cybertruck’s front camera. Interestingly, Tesla did not include a washer for the rear camera, which is possibly the worst culprit when it comes to accumulated dirt and grime. The side cameras are somewhat protected due to their positioning, and the front-facing windshield cameras are able to benefit from the vehicle’s wipers.
Whatever the solution ends up being, it will be a welcomed addition, especially for Canadian winter drivers.
