What Are Drone Cleaning Services?
Drone cleaning services use specialised unmanned aircraft equipped with high-pressure water spray systems to clean building exteriors, solar panels, and rooftops without scaffolding, gondolas, or rope access. In Singapore, where thousands of high-rise buildings require regular exterior cleaning, drone technology offers a transformative alternative to traditional methods that are slow, expensive, and inherently dangerous.
Our cleaning drones carry hydro-jetting nozzles connected to ground-based water pumps through a tether system. The drone flies along the building surface at controlled speed and distance, applying calibrated water pressure to remove dirt, algae, moss, pollution staining, and biological growth. For sensitive surfaces like glass and solar panels, deionised water is used without chemicals to prevent damage to coatings and seals.
Singapore's tropical climate — with year-round high humidity, frequent rain, and intense UV radiation — creates ideal conditions for biological growth on building surfaces. Algae, mould, and lichen colonise facades within months. Traditional cleaning methods require scaffolding erection (weeks of setup, massive cost) or gondola systems (slow, limited by building design). A drone cleans the same surfaces in hours, not weeks, at a fraction of the cost. CAAS-approved drone cleaning is now the fastest-growing segment of Singapore's building maintenance industry.
Our Drone Cleaning Services
Facade Cleaning
Facade drone cleaning for high-rise buildings — concrete, glass curtain walls, metal cladding, and tile facades. Hydro-jetting removes years of accumulated grime without scaffolding. Ideal for condominiums, commercial towers, and HDB blocks.
Window Cleaning
Drone window cleaning for commercial buildings, office towers, and glass facades. Water-fed drone system delivers streak-free results on glass surfaces up to 50+ storeys. No gondola or rope access required.
Solar Panel Cleaning
Solar panel cleaning by drone using deionised water — no chemicals, no detergents, warranty-safe. Removes dust, bird droppings, and biological growth that reduce solar output by 15-25%. Ideal for rooftop and ground-mount arrays.
Roof Cleaning
Drone roof cleaning removes algae, moss, lichen, and dirt from commercial and industrial roofs. No foot traffic on the roof surface — eliminating fall risk and roof membrane damage from workers walking on the roof.
How Drone Cleaning Works
Site Assessment
We visit the building to assess surface materials, contamination type and severity, building height, surrounding obstacles, and water supply access. CAAS activity permits are applied for and secured. The cleaning approach and pressure settings are determined based on the surface type.
Equipment Setup
On cleaning day, our team sets up the ground-based water pump, hose system, and drone platform. Exclusion zones are established at ground level. Water supply is connected — either mains water or our own tank supply. For solar panels, deionised water systems are prepared.
Drone Cleaning Operation
The drone pilot systematically cleans the surface in overlapping passes, maintaining consistent distance and spray angle. Pressure is adjusted in real time based on contamination levels and surface response. A visual spotter monitors cleaning effectiveness from the ground.
Quality Check and Documentation
After cleaning, we conduct a visual quality check using the drone camera to verify complete coverage. Before-and-after photographs are captured for the client. Any areas requiring additional attention are re-cleaned on the same visit.
Drone Cleaning vs Traditional Methods
| Factor | Drone Cleaning | Scaffolding | Gondola / BMU |
|---|---|---|---|
| Cost (20-storey building) | $3,000 — $8,000 | $20,000 — $50,000 | $8,000 — $15,000 |
| Time | 1-3 days | 2-4 weeks (incl. setup) | 1-2 weeks |
| Safety risk | Zero fall risk | High — scaffold erection | Moderate — working at height |
| Disruption | Minimal — no road closures | High — hoarding, footpath closure | Moderate — gondola noise |
| Building access | No contact with building | Physical attachment required | Requires BMU installation |
| Suitable height | Up to 50+ storeys | Typically up to 20 storeys | Any height (if BMU installed) |
Drone Cleaning Pricing in Singapore
Our cleaning pricing is transparent and based on surface area, building height, and contamination level. Every quote is fixed-price.
| Service | Typical Scope | Price Range (SGD) |
|---|---|---|
| Facade Cleaning | High-rise exterior | $3,000 — $15,000 |
| Window Cleaning | Commercial glass facades | $2,000 — $8,000 |
| Solar Panel Cleaning | Rooftop/ground-mount arrays | $1,000 — $5,000 |
| Roof Cleaning | Commercial/industrial roof | $1,500 — $5,000 |
| Building Exterior Cleaning | Cladding, concrete, panels | $2,000 — $10,000 |
| Condo Cleaning (MCST) | Facade + common areas | $3,000 — $10,000/visit |
Prices include: CAAS permit application, drone and equipment mobilisation, water supply, cleaning operation, quality check, and before/after photo documentation.
Why Choose Drone Cleaning in Singapore
- No Scaffolding Required — eliminates the single largest cost component of traditional facade cleaning. No erection time, no rental costs, no footpath closures or hoarding.
- Zero Fall Risk — all operators remain safely on the ground. No rope access, no gondola work, no working at height. This eliminates MOM workplace safety incident risk entirely.
- Minimal Disruption — drone cleaning operates from a small ground footprint. No road closures, no scaffold hoarding, no prolonged visual obstruction. Residents and tenants are barely affected.
- CAAS Approved — our operations hold current CAAS activity permits. Flight plans, safety protocols, and standard operating procedures are approved by Singapore's aviation authority.
- Surface-Safe Technology — pressure and distance are calibrated for each surface material. Glass, cladding, concrete, tile, and solar panels each receive the appropriate treatment. No damage, no voided warranties.
- Combined Inspection + Cleaning — we can combine drone cleaning with facade inspection in a single visit, identifying defects while cleaning the surface. This dual-purpose approach saves time and cost for building owners.
