Photovoltaic cleaning drone
A 20 L airborne-tank system for solar arrays — 60 m² per flight, six flights per hour.

Key performance
Overview
Facade models (QY-QX-420, QY-X4-40) are tethered to a ground high-pressure washer through a braided hose, allowing continuous cleaning at heights of up to 120 m without scaffolding or gondolas.
Photovoltaic models (CD20, CD50) carry an onboard water tank and spray system for solar arrays, with RTK positioning and radar for stable, repeatable passes.
