The nozzle is where the cleaning actually happens. Getting it right means better cleaning results, less water waste, and no surface damage. Getting it wrong can mean streaking, missed areas, or worse — etching and coating removal.
Nozzle Types
Fan Nozzle (Flat Spray)
Produces a flat, wide spray pattern. Good for even coverage on flat surfaces. Available in different angles — wider angles give more coverage but lower impact force.
Cone Nozzle (Full or Hollow)
Produces a circular spray pattern. Full cone gives even distribution across the circle. Hollow cone concentrates flow on the edges. Used for rinsing and pre-wetting.
Pencil Jet (Zero Degree)
Concentrated, high-impact stream. Used for stubborn staining on durable surfaces. Not suitable for glass, coated panels, or delicate materials.
Matching Nozzle to Surface
| Surface | Nozzle Type | Angle |
|---|---|---|
| Glass facade | Fan nozzle | 40–65° |
| ACP cladding | Fan nozzle | 25–40° |
| Concrete | Fan or pencil | 15–25° |
| Solar panels | Fan nozzle | 40–65° |
| Metal roofing | Fan nozzle | 25–40° |
Flow Rate and Distance
Flow rate (litres per minute) and distance from the surface work together. Too close with too much flow can damage surfaces. Too far and you lose cleaning effectiveness. Our drone system maintains a consistent distance from the surface using sensors, which keeps the spray pattern uniform throughout the pass.
