UK Manufactured Cleaning Drones for Industrial Infrastructure
Are you a Facilities Manager looking for a fast, modern and safe way to maintain your site & assets?
Clean Hard-to-Reach Assets
Our IP55-rated hardware is built for the demanding conditions of refineries, manufacturing plants, and industrial complexes.
Our systems access areas where restricted terrain prevents standard lift deployment.
Maintain High-Altitude Stability
With a 3:1 thrust-to-weight ratio, our systems maintain a stable hover and consistent spray distance even in high-altitude turbulence.
By operating from the ground, you minimize site congestion and eliminate the major liability of working at height in high-footfall areas.
Work in Urban Environments
Our Radar-driven and real-time camera surface tracking allows for precise facade maintenance without the need for hanging cradles or boom-arm installations.
Our surface-tracking technology goes beyond static mapping, calculating blade flex in real-time to prevent collisions and maintain a safe standoff distance.
Protect your assets with high-flow soft washing
Cleaning large scale infrastructure is no longer a challenge with an Aspira AC4.2 wash drone
Constant exposure to the elements leads to corrosion, organic growth and structural fatigue. Left unchecked, these factors evolve into critical maintenance failures and significant capital expenditure.
Aspira replaces dangerous manual labour with precision British engineering. By utilizing our CLIVE intelligence protocol and Advanced Surface Tracking, your drone pilots can deliver scheduled soft-washes that lock to the surface of your most complex assets.
Because we prioritize high flow rates over damaging pressure, our systems safely remove contaminants, preserve your site’s aesthetic and drastically reduce long-term operational downtime. Unlike standard quadcopters, our industrial octocopter design ensures total hardware redundancy, keeping your site, and your people, safe.
The Aspira AC 4.2
The multi-role, CE and C5 certified, autonomous, workhorse of wash drones
Our Aspira AC cleaning and wash drone is the pinnacle of both engineering excellence and innovation. Purpose built for cleaning a variety of assets using both high-pressure and soft wash techniques.
The AC 4.2 is available in three variants which are all based on the same subframe allowing future upgradability.
Our AC Basic model is suitable in non-urban environments where the only requirement is a specific type of clean - for example, a solar farm.
Our flagship AC Ultimate has the additional feature being able to fly in GPS denied areas within an urban environment, where tall building will regularly disrupt any GPS signal.
Case Study | The MET Office
The MET Office before cleaning and treatment
The wall was cleaned with the central area given an anti-fungal coating
At the 9 month evaluation point, the treated area remained clear
Project Overview
Objective
To evaluate the residual efficacy of Aspira’s anti-microbial "de-greening" coating compared to standard industrial cleaning alone. The study was conducted on a 125sqm vertical facade at the Met Office headquarters, a site with high exposure to organic spore loads.
Phase 1: Baseline & Preparation
- Initial State: Significant biological degradation and algae colonization were present across the masonry.
- Environmental Constraints: The presence of active avian nesting sites required a pH-neutral, non-toxic solution. The application was completed without site closures or disruption to local biodiversity.
Phase 2: Controlled Application (A/B Test)
The entire 125sqm facade was mechanically cleaned to remove surface contaminants. Immediately following the clean, a bespoke anti-microbial coating was applied to the center section only, leaving the surrounding cleaned masonry as a control variable.
Phase 3: Verification & Results (9-Month Audit)
A longitudinal review was conducted nine months post-application to measure the "regrowth delta" between the treated and untreated zones.
- Treated Zone (Center): Maintained 100% surface integrity. The coating continued to neutralize spores through the winter humidity cycle, preventing any organic recolonization.
- Control Zone (Surrounding Area): Algae and biological staining had begun to reappear, demonstrating that standard cleaning alone is insufficient for long-term facade preservation in high-damp environments.
- Longevity Projection: Based on the 9-month performance, the treated area is projected to remain clear for 18+ months, effectively doubling the standard maintenance interval.
Technical FAQ
No. At operational heights, the system is engineered for low-pressure, low-flow output typically delivered through a 1/4 inch line.
This ensures the kinetic impact of the water remains well below the erosion threshold for Leading Edge Protection (LEP). For offshore or coastal assets, we utilize specialized desalinization solutions to neutralize salt crust without abrasive force.
Drift is managed through a combination of precision nozzle selection and calculated standoff distances.
As part of our comprehensive operator training, we provide the specific formulas to calculate drift based on wind speed and height.
We also provide standard operating procedures (SOPs) for public notification and environmental boundary setting to ensure all site-specific liabilities are mitigated.
Traditional scrubbing or high-pressure "point" cleaning can often void warranties.
Aspira uses a Soft Wash methodology; combining low PSI with high flow rates to flush away contaminants without mechanical stress on the glass.
The system is compatible with heated, de-ionized water for first-time deep cleans, ensuring a residue-free finish that maintains the panel's refractive integrity and manufacturer compliance.
Our AC4.2 drone utilizes a redundant 8-motor (Octocopter) configuration.
Unlike standard quadcopters, this propulsion system is designed to maintain stable flight and execute a controlled, safe landing even if a motor fails.
This redundancy is a core requirement for working over expensive industrial infrastructure.
High-rise environments often suffer from so called Urban Canyon GPS interference. Our AC4 Ultimate drone utilise GPS-independent surface sensing and LiDAR to maintain a fixed distance from the structure.
The AC4 Ultimate sees the building in real-time and adjusts its position relative to the surface, not a satellite, ensuring a steady hover even in turbulent wind conditions.
Data security is handled at the hardware level. All flight data and camera feeds are processed locally on the device with no remote uplinks or cloud-based storage.
Our systems are essentially air-gapped; there is no data scraping and no background transmission.
For high-rise commercial work where privacy is a priority, the camera feed can be completely disabled, allowing the drone to operate solely via its LiDAR proximity sensors and radar.
Aspira is a British manufacturer. We prioritize sovereign supply chain integrity, utilizing British safe components and domestic engineering.
In an era where "data-scraping" and foreign hardware vulnerabilities are a major concern for national infrastructure, we offer a transparent, secure alternative.
Because we build and support our tech in the UK, you have full visibility over the hardware's origin and total control over your operational data.
