Flexible Tethered Drone Cleaning for Stone Facades After the rainy season, stone curtain walls often suffer from heavy moss buildup. Traditional cleaning methods are inefficient, and conventional drones can’t perform close-range, high-pressure cleaning. The P3 (T50), equipped with a flexible joint system and tethered high-pressure spray, enables ultra-close, multi-angle cleaning. Combined with the DIC water treatment system, it removes moss, dust, and grime with no blind spots or residue. Key Features -12 MPa (optional 20 MPa) high-pressure cleaning -Ultra-close, multi-angle spraying -Zero-distance, no-residue operation -600㎡/h cleaning efficiency
