Drones Are Reshaping Exterior House Cleaning

Updated: Apr 22

In the ever-evolving landscape of technology, drones have emerged as transformative tools

across various industries. In this article, we will delve into the ways drones are revolutionizing the traditional methods of maintaining the outward appearance of houses, offering efficiency, safety, and precise exterior house cleaning.

The Evolution of Exterior House Cleaning

Historically, exterior facade cleaning has been a labor-intensive and often risky endeavor. From manual scrubbing to the use of scaffolding and high-pressure hoses, the methods were effective but came with inherent challenges.

Enter drones – unmanned aerial vehicles equipped with advanced cleaning mechanisms, promising a leap into the future of cleaning homes with a variety of siding to include: vinyl siding, fiber cement board siding (Hardie Plank), metal siding, brick, stone veneer, stucco, engineered wood, synthetic stone, and stone.

How Do Drones Clean Houses?

Drones equipped with state-of-the-art cameras and sensors navigate house exteriors with unparalleled precision. This allows for a comprehensive assessment of the cleaning requirements and ensures that every inch of the facade is addressed.

The payload capacity of modern drones enables the integration of specialized cleaning tools. High-pressure nozzles and environmentally friendly cleaning agents can be deployed to effectively remove dirt, grime, and pollutants. Depending on the house exterior materials, a cleaning drone is used to soft wash or pressure wash dirt and grime. Sometimes a combination of pressure washing and soft washing needs to be used.

Drone Soft Washing vs Pressure Washing

Cleaning Drones can be used to pressure wash houses and soft wash houses. Depending on the material and type of build-up accumulating on a house facade - a cleaning drone will be prepared with the proper pressure settings and cleaning mixture.

Soft Washing relies on low-pressure water combined with specialized cleaning solutions to remove contaminants. It is highly effective in removing organic stains like algae and mildew, and it provides long-lasting results due to the use of cleaning agents.

Pressure Washing involves the use of high-pressure water to forcefully remove contaminants from surfaces. It is highly effective in quickly removing built-up dirt, grime, and stubborn stains from surfaces. However, it may not be as gentle on more delicate materials.

Soft Washing Pressure Level

The pressure used in soft washing is significantly lower than that of traditional pressure washing. It typically ranges from 100 to 500 PSI (pounds per square inch).

Soft Washing Cleaning Solutions

Soft washing involves the use of a naturally biodegradable degreaser and stain remover. These solutions break down contaminants and aid in their removal without relying solely on high-pressure water.

Suitable Surfaces For Soft Washing

Soft washing is ideal for a range of surface materials that attract organic growth and stains. Surfaces include but are not limited to:

  1. Painted wood siding

  2. Stucco siding

  3. Vinyl siding

  4. Roof shingles

  5. Concrete walls

  6. Brick walls

  7. Block walls

  8. Stone walls

Soft washing minimizes the risk of damage to these surfaces compared to only high-pressure washing and helps prohibit organic growth from returning to these surfaces.

Pressure Washing Pressure Level

Pressure washing typically uses higher pressure levels, ranging from 1,500 to 4,000 PSI. This makes it more suitable for tougher surfaces like concrete, brick, and some types of stone.

Pressure Washing Cleaning Solutions

While pressure washing can be done with water alone, cleaning solutions can be added to enhance the cleaning process. However, the primary cleaning action is driven by the force of high-pressure water.

Suitable Surfaces For Pressure Washing

Pressure washing is well-suited for harder surfaces that can withstand the force required to treat stubborn areas and remove debris (spider webs, etc.). Surfaces include but are not limited to:

  1. Concrete walls

  2. Brick walls

  3. Block walls

  4. Some types of stone walls

  5. Some types of roof materials

Advantages of Drone-Powered Facade Cleaning

Safety First

One of the most significant advantages is the enhancement of safety. Traditional facade cleaning often involves risky climbs or the use of scaffolding, posing potential hazards.

Drones eliminate the need for human presence at heights, minimizing the risk of accidents and injuries.

Efficiency and Time Savings

Drones operate with efficiency and speed, significantly reducing the time required for facade cleaning. The swift navigation and targeted cleaning mechanisms contribute to a quicker turnaround, benefiting both service providers and building occupants.

Cost-Effective Solutions

While the initial investment in drone technology may seem substantial, the long-term cost savings are undeniable. The reduced need for manpower, scaffolding, and associated safety measures leads to a more cost-effective solution for building maintenance.

Applications Across Industries

Residential Homes

Drones are not limited to towering structures; they are equally applicable to residential homes. From roof cleaning to window washing, drones bring exterior maintenance within reach for homeowners, offering a hassle-free alternative to traditional methods.

Commercial Buildings

High-rise structures with intricate architectural designs can be challenging to clean manually. Drones provide a scalable and efficient solution for commercial building maintenance, ensuring a pristine facade that reflects a positive image.

Addressing Challenges and Concerns

Regulatory Compliance

The integration of drones into exterior cleaning services necessitates compliance with existing regulations. Ensuring adherence to privacy and safety standards is essential for the responsible deployment of this technology.

Environmental Considerations

As with any cleaning process, the choice of cleaning agents and materials is crucial. Emphasizing environmentally friendly solutions aligns drone facade cleaning with sustainable practices.

The Future Landscape

As drones continue to evolve, the future of exterior facade cleaning looks promising. Innovations in battery life, payload capacity, and cleaning technologies will further solidify drones as indispensable assets in the maintenance of buildings. The skies above our cities may soon be filled with these aerial cleaners, ensuring a cleaner, safer, and more efficient urban environment.


In the grand narrative of technological progress, drones have emerged as key players in reshaping various aspects of our lives. In the realm of exterior facade cleaning, their impact is nothing short of revolutionary. From enhancing safety to delivering unparalleled efficiency, drones are transforming the way we approach home and building maintenance.

As we look to the skies, it becomes evident that the future of facade cleaning is airborne, propelled by the steady hum of drones working tirelessly to keep our urban landscapes gleaming.
