Top Benefits of Using Drones for Facade Cleaning

Introduction

Cleaning your exterior facades, especially high-rise structures, often comes with lots of risks as a result of scaffolding, rope access, and high labour costs. Conversely, drones are transforming how building exteriors are cleaned due to evolving technology. This article explains in detail the benefits you’ll get when using drones for facade cleaning to ensure you have the required knowledge.

Benefits Of Drones In Exterior Facade Cleaning and High-Rise Window Cleaning

Improve Workers Safety

Construction has a disproportionate share of workplace deaths. In 2023, about 1 in 5 U.S. workplace fatalities (20.8%) occurred in construction. Within construction, falls, slips and trips were the largest driver of deaths. OSHA’s “Fatal Four” identifies four leading killers in construction falls, struck-by, electrocution, and caught-in/between which consistently account for the majority of construction deaths. Controls target eliminate or reduce exposure to these hazards.

An instance that shows drones’ effective cleaning is Dubai’s Burj Khalifa. Publicly documented maintenance of the Burj Khalifa remains primarily rope-access and building-maintenance units (BMUs), with crews requiring about 3–4 months to complete a full exterior cycle. 

Modern cleaning drones are built to guarantee you a high level of safety. The features that guarantee this safety include:

• Collision Avoidance System: It helps drones eliminate structural impact like trees, buildings, people, and other aircraft when the drone is at work.
• Redundant Propulsion Systems: This helps drones maintain stability in mid-air. The redundant propulsion systems include motors, propellers, or power components. They ensure the drone continues its operations instead of crashing if one part fails.
• Wind Resistant Designs: Features up to 45 mph gusts. This helps drones remain stable, controllable, and safe in windy conditions.
• Tethered Power Systems: Prevent battery: This feature helps drones connect to the ground by a cable (tether). This cable gives continuous electrical power, ensuring drones stay airborne for days instead of relying on onboard batteries.
• Live Monitoring Capabilities: This allows the drone to record and transmit real-time video, images, or sensor data to a ground control station, mobile device, or command center. This simply means you can see what the drone sees while it’s working.

With these technologies in drones, the stress you encounter with high facade cleaning is eliminated, ensuring you only pay attention to operating the drones rather than risking your life to physical dangers. This guarantees you reduced insurance costs and liability. Plus, it’s in compliance with OSHA fall protection standards.

Low operating Cost

There are three factors for reducing your cost up to around 40-60% when utilizing drone cleaning for high facade.:

• Equipment Cost: Since there’s no need for scaffolding and lifts, using drones for facade cleaning gives you a reduced cost of up to 40-50%. For instance, you may spend up to $30,000 to $50,000 per project when utilizing traditional cleaning that requires scaffolding. Meanwhile, all you need is to purchase a drone system once. The price ranges between $35,000 $45,000.  This is beneficial, as you can get back your invested money when you secure two to three gigs. 
• Labour Savings: You need up to 6-8 workers to complete a facade cleaning when utilizing the traditional cleaning method; meanwhile, you only need two operators for drones. This means you can reduce your labor cost from $150,000 to just $30,000 per project by using drone cleaning methods for your facade. 
• Continuous Savings: Using drone cleaning methods for your facades gives you reduced insurance premiums by 30-40%. It helps you split your annual maintenance by 50%, and you eliminate the cost of renting scaffolding daily. 

The above costs increase as your building complexity increases when utilizing traditional cleaning; meanwhile, drone cleaning helps you modestly increase the cost by 10-20%, especially for challenging projects. This means you can prioritize drones for your urban maintenance; they guarantee you a reusable system while ensuring your safety.

Quick Completion Time

Not only does a drone help you save costs, but it also allows you to complete complex projects quickly. This means you can complete projects that take weeks with traditional cleaning methods in just a few days with the drone cleaning method. There are many instances where drone cleaning has cleaned high facades of 30-story, 615,000-square-foot facades in only 3 days, which would have been completed with traditional cleaning in 2 weeks. This is proof that using drone cleaning for your facades guarantees you up to 78% reduction in cleaning time. 

The list below shows the main reasons drones are more efficient for your facade.

Simultaneous Operations: The operations are such efficient that you can use multiple drones to clean large areas at the same time. For instance, you can use three drones to clean 1,200m² in just 3 hours, while traditional cleaning methods take two days.

Requires Less Time To Set Up: You do not need to set up scaffolding and other prep work that takes time when using drones to clean your facades. Unlike traditional methods that require days of preparation before you commence work, cleaning with drones allows you to start working immediately. 

Continuous Operation: Drones can work for long hours without stopping. Plus, drones feature high-pressure systems that allow them to work on large areas of your facades quickly and efficiently. Meanwhile, human beings get tired and go for a break when using traditional methods. 

The table below shows the differences in the efficiency of both traditional methods and drone cleaning methods in a 50-story building: 

The overall speed of using drones in your traditional cleaning guarantees you’ll get less disruption, more frequent cleaning, faster emergency response, and allows you to easily adapt to varying weather conditions.  

Minimal Water Usage

There’s no need for you to use excess water when you’re cleaning your facades with drone cleaning. Unlike traditional methods that require a large amount of water to complete washing jobs, drones reduce the use of water by 60-80%. In the real world, a company operating in a 30-story building in Australia was using 2,000 gallons of water while it was using traditional cleaning methods. Meanwhile, it started using just 500 gallons when it switched to drone cleaning. This precision not only saves water for the company but also guarantees effective cleaning. 

You can find this level of advancement in drones due to the following features:

• High-pressure nozzles for maximizing coverage
• Smart sensors that adjust the drone’s water flow based on dirt levels. 
• Precision Controls, specifically built for specific surfaces.
• Closed-loop systems for water conservation.

High Accuracy Cleaning

Modern drone cleaning systems feature tools like LiDAR technology, high-resolution sensors, and GPS positioning. Plus, they come with 3D mapping to ensure you have the best result regardless of your facade height. For instance, you’ll get up to 1-2 cm accuracy if you utilize the Lucid H1 drone system for cleaning your facades. This precision helps you minimize frequent modification in your work, ensuring you save cost, time, and water while helping you focus on the cleaning areas that really matter.

Drones systems give you high accuracy cleaning in your facades through the following technologies:

• The high-resolution cameras give you a detailed capture of high altitudes through images and videos, thus helping you find details clearly.
• GPS in drones helps you determine the precise location of the drone anywhere on Earth through the use of satellite signals.
• Inertial measurement units in drones measure motions, orientation, and acceleration. This feature gives drones a deep understanding of how they’re moving in 3D space. 

Access To Complex Area

Drones are recommended if you want effectiveness in maintaining your intricate designs in your modern urban architecture. Due to their precision cleaning in cleaning facades, you can use them to handle hard-to-reach areas like recessed windows, decorative features, and tight spaces in buildings. You can also minimize water usage when you apply a specific cleaning approach to each area of the building. 

The following features are the built-in technology that allows drones to clean complicated areas:

• Obstacle avoidance sensors are the eyes and ears of drones. They enable drones to detect and avoid obstacles such as trees, walls, buildings, poles, or people in their flight path.
• Angled spray heads are nozzles mounted on a drone that are tilted at a specific angle, rather than pointing straight down. They guarantee improved spray coverage, accuracy, and efficiency when liquids like fertilizers, pesticides, or herbicides are applied over crops.
• Moving spray heads are spray nozzles that allow drones to change their position or angle during flight, rather than staying fixed in one direction.

Technologies in drones give you consistent results in various materials, like:

• Glass: Drones use a purified water system that prevents scratches in your glass materials.
• Metal: Specialized anti-corrosion treatments and controlled detergents protect metallic surfaces.
• Stone: Pressure-controlled jets regulate water force to clean stone gently yet effectively.
• Textured Surfaces: Custom brush or spray attachments reach into grooves and patterns, removing embedded dirt or residue.

Building Inspection Features

Not only can you use drones for cleaning, but you can also rely on them as an inspection tool to inspect your buildings, making them suitable for maintaining your building. For instance, in 2022, the entire Empire State Building was inspected with drones. After drones inspect all 102 stories in just three days, they identify 35 cracks and 5 moisture risks that you cannot inspect and detect with traditional methods of cleaning.

The following advanced technologies allow drones to work seamlessly during your facade cleaning:

• Thermal imaging sensors are also called infrared cameras, allow drones to see and measure heat instead of visible light. 
• Real-time data processing through GPS and IMU systems, radar sensors, and cameras guarantees instant analysis and interprets the data it collects instantly while it’s still working, instead of processing it after the flight. 
• AI defect detection allows drones to use Artificial Intelligence (AI) to identify faults, damages, or irregularities on objects or structures.

The subsequent paragraph explains in detail how the above technologies improve your facade building maintenance:

• Real-time monitoring: Drones also gather and process information on the situation of your buildings during the course of cleaning, ensuring issues are detected immediately. This means you can quickly fix problems to eliminate costly repairs over time. Plus, it also helps your facade last for a long time since you discover issues that might make your facade fail over time.
• Thorough Coverage: You can inspect up to 400,000 square feet of facade in a day with just one drone. They give you a precise cleaning in tricky areas like spires and underhang spots that you cannot reach with traditional methods. 
• Data Driven Maintenance: You can have real-time wear and tear results, predict your maintenance needs, and areas of your facade that need repairs in your building with drone digital records. This guarantees you a reduced cost of repairs up to 40%, ensuring you save more due to the reduced cost you get with drone systems already. 

Environmental Benefits
