Overview
A heavy-duty facade-cleaning drone for towers up to 120 m, with remote detergent dosing.
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.
Key features
- Cleans facades up to 120 m with ±3° attitude stability
- Remote-controlled dosing washer with electric ratio mixing of detergent
- 200 m hose reel and 150 m braided high-pressure hose
- Autonomous ground station: waypoints, vertical A-B cleaning mode, geofence, low-battery and lost-link return
- Telescopic carbon-fiber spray boom and front radar
