China UAV Procurement Guide Introduces First-Ever Selection Standards for Building Cleaning Drones

UAV Building Cleaning Solutions: Procurement Decision Framework

Three Core Value Pillars

Building exterior cleaning using UAVs is a highly complex and systematic task. With the emergence of diverse technological routes, models, and features, solution selection has become increasingly difficult, raising decision-making costs for cleaning service providers, property managers, and other end users. In response, a dedicated "UAV Building Cleaning Solution Procurement Decision Framework" has been developed, summarizing key evaluation criteria to support efficient, targeted decision-making.

Final Goal:

Safe, Clean, and Cost-Effective Unmanned High-Altitude Cleaning

1. Baseline Requirement

Ensure Comprehensive Safety for Personnel, Equipment, Buildings, and the Environment

Ability to resist flight disturbances and spraying recoil in real time

Safety measures for accidental drone-to-building contact

Controlled water mist diffusion to minimize environmental and chemical impact

Easy compliance with different operational airspace regulations

2. Key Capability

Deliver Clean Results with No Streaks or Residues

Ultra-close operation to maximize cleaning force

Fine control of water usage to avoid watermarks or residue

Effective cleaning of architectural blind spots, including facades, rooftops, and undersides

Ability to handle various contaminants of different severity and composition

No leftover cleaning agents in crevices, frames, or sealants after operation

3. Economic Value

Achieve a Lower Cost Per Square Meter Compared to Manual Cleaning

Significantly higher efficiency than traditional manual cleaning

Long-term, consistent, high-quality performance with no rework

High equipment reliability to minimize safety-related losses

Standardized training system ensures operators are easy to recruit and low cost

Low consumption of water, electricity, and other consumables

Reduced insurance and maintenance costs for personnel, equipment, and operations

4. Additional Features

Enhance Operational Experience and Service Capabilities

High maneuverability between buildings, adaptable to complex environments

Compact, integrated system for easy transport, deployment, and use

Low-noise operation to minimize impact on surrounding environment

Intelligent work support functions such as route planning and dual tethering (water and power)

Reliable after-sales and technical support for long-term use

As outlined in the UAV Procurement Guide, a solution that truly meets market demands must focus on the core nature of high-altitude cleaning tasks and deliver value in three key areas: safety, cleaning effectiveness, and cost-efficiency. These place significant demands on innovation, system stability, and functional integration:

① Safety as a Baseline

While drones offer a clear safety advantage by removing workers from high-risk environments, there are multiple safety dimensions beyond personnel risk—such as potential building damage, drone malfunction, and environmental impact—that must be addressed. This makes real-time anti-disturbance capabilities, precise mist control, and safe collision protection essential selection criteria.

② Cleanliness as Core Capability

Achieving a clean, streak-free result requires resolving several challenges: sufficient water pressure, versatility in cleaning different types of stains, full coverage of complex surfaces, and prevention of cleaning agent residue. Therefore, a robust solution must provide:

Close-Proximity Operation – for optimal cleaning force

Multi-Stain Cleaning Technology – adaptable to various dirt types

Water Control Precision – ensuring a dry, spotless surface

Blind Spot Cleaning – addressing edges, frames, and hidden corners

Residue Control – leaving no chemical traces behind

③ Cost-Effectiveness as Practical Value

Whether purchased by service providers or property owners, economic efficiency is a key factor in procurement. UAV-based building cleaning must not only outperform manual methods in safety and effectiveness but also demonstrate clear advantages in cost control to support large-scale deployment and application.

By integrating flexible embodied robotics and intelligent water treatment systems, modern UAV-based cleaning solutions are achieving unprecedented levels of operational safety and cleaning performance. These systems support zero-distance operations with strong resistance to disturbances, adaptive balance control, and multi-angle cleaning coverage. Advanced water treatment technologies further ensure minimal environmental impact, with evaporation rates of up to 99.9% post-cleaning.

These capabilities are now being deployed across a wide variety of building types nationwide—from office towers and hotel residences to factories, municipal facilities, and uniquely shaped structures—providing reliable, efficient, and eco-friendly high-altitude cleaning services that are increasingly recognized by leading clients across industries.
