DJI Agras mist nozzle vision system and landing gear cleaning flow

DJI Agras Mist Nozzle Vision-System & Landing-Gear Cleaning Guide

September 18, 2026

The T100/T70 Series Mist Nozzle Package changes more than the spray pattern. DJI specifically warns that droplets from the additional sprinklers can affect the aircraft vision system and that sprayed liquid can collect on the landing gear. These are operating and maintenance concerns, not optional cosmetic cleanup.

Quick Answer: Clean the vision-system cameras before and after spraying, fly cautiously because spray droplets may affect vision-system performance, and clean liquid residue from the landing gear after use to reduce pesticide-related damage.

Before spraying: clean the vision cameras

DJI explicitly instructs operators to clean the cameras of the vision system before spraying. Start with clean optical surfaces so any degradation during the operation is not being layered on top of existing dust, residue or pesticide film.

During spraying: treat droplets as a sensing condition

The product-information sheet says the performance of the vision system may be affected by spray droplets after the additional sprinklers are mounted. Fly with caution and do not assume obstacle-sensing behavior will be unchanged in mist-heavy conditions.

After spraying: clean the vision cameras again

Repeat the camera cleaning after spraying. This is not merely a storage step: it helps remove droplets and residue that can remain on optical surfaces and affect the next operation.

Clean the landing gear

DJI also warns that liquid sprayed from the additional sprinklers may remain on the aircraft landing gear. Clean the residue to avoid pesticide damage.

Do not confuse cleaning with a failed sensor diagnosis

If the aircraft shows a vision-system warning after mist operations, first separate contamination from hardware failure. Clean the optical surfaces and inspect for residue before assuming the affected component needs replacement.

For T100-specific sensor servicing, use the T100 Radar, LiDAR, RTK & Vision Maintenance Guide. For daily aircraft cleaning after spraying, use the T100 End-of-Day Spray Cleaning Guide.
