ALPHA
Compact professional drone for facades, Roofs & solar panels

Professional drone cleaning made simple
The ALPHA low-pressure cleaning drone has been specifically developed for professional cleaning and low-pressure spraying applications.
Rather than simply adding a spraying system to a conventional drone, ALPHA is supplied as a complete, ready-to-use professional cleaning solution with the essential equipment required to get started.
Thanks to its ultra-compact design, low weight and high manoeuvrability, ALPHA can efficiently access difficult-to-reach areas such as roofs, facades, solar panels, cladding and industrial structures.
It is an ideal solution for companies looking to enter the professional drone cleaning market or expand their existing cleaning services with a compact and efficient system.
C5/C6 Class marking for greater
operational flexibility
The ALPHA is available with C5/C6 class marking, providing greater flexibility for professional drone operations under the applicable European Standard Scenarios.
Greater Flexibility
The ALPHA is not limited to cleaning applications and can also be configured for other professional spraying operations.
Non-Tethered Operation
Unlike a captive cleaning drone connected to a ground anchor, the ALPHA can operate as a non-tethered drone in the appropriate configuration.
C6 Operations
The C6 configuration is intended for operations under STS-02, subject to the applicable operational requirements, pilot qualifications and authorisations.

Low-pressure spray gun for professional facade cleaning
The professional low-pressure spray gun provides a working range of up to 6 metres, allowing larger facade areas to be treated efficiently.
Because the system operates at lower pressure, the operator can maintain a greater distance from the facade, providing greater control when treating difficult-to-access areas.
