About this Product/Service
The window (vertical) cleaning industry has undergone a dramatic transformation in recent years, with Principle Cleaning Services (Principle) at the forefront of this. Vertical cleaning has rapidly evolved into one of the company’s most dynamic and fastest-expanding divisions and is the second-largest operation of its kind in the UK.
At the core of this is a commitment to innovation, with technology enhancing efficiency, transparency and safety. From pioneering drone cleaning to advanced, cloud-based systems, Principle is redefining what's possible in cleaning at height.
In 2024, Principle integrated drone technology into its service offering. Previously inaccessible areas of buildings across London are now within reach. Drone window cleaning reduces cleaning time by up to 75%, delivers zero-emission operation and significantly enhances safety, efficiency and sustainability. The response has been outstanding, leading to the launch of the company’s drone cleaning division.
However, long before drone window cleaning, Principle was already leading the way in cleaning innovation with a suite of technologies created inhouse. A flagship example is PCS Hub - a secure, cloud- driven platform accessible across all devices - which gives clients instant access to real-time operational insights, enabling faster, smarter decision-making.
Integrated within PCS Hub is 3D Mapping, a proprietary tool that offers critical visibility across entire estates - down to individual windows! It allows clients to track cleaning activity, assess quality standards, and log defects in real time, bringing new levels of control and accountability.
Drop Marking is a daily-use technology that logs the duration of each window cleaning drop. This data feeds directly into 3D Mapping, forming a closed-loop, analytics-driven system that tracks progress, maximises performance and optimises resources.
This network provides clients with real-time reporting on project timelines, compliance, financial information and resource allocation, ensuring complete transparency and delivering measurable value. Clients always know exactly what’s being delivered.
