Drone high-access cleaning in Thionville

Cleaning drones project water and treatment solutions at high pressure onto high surfaces, without scaffolding, lift platforms or rope access: roof moss removal, facade cleaning, industrial cladding, soiled photovoltaic panels, glass canopies and steel structures. Fed from the ground through a hose connected to a pumping station, the drone treats 300 to 500 m² per hour depending on the surface — two to four times faster than traditional access methods, at a markedly lower cost as soon as the height exceeds two storeys.

We match the treatment to the substrate: low-pressure rinsing with deionised water for solar panels (no streaks), certified moss killer for roofs, appropriate detergents for cladding and render. The gain is not merely cosmetic: clean panels recover several percent of output, a de-mossed roof lasts longer, maintained cladding keeps its manufacturer warranty.

Common use cases

The local context in Thionville

Moselle's second city, Thionville lives to the rhythm of neighbouring Luxembourg: tens of thousands of cross-border workers transit daily via the A31 and the station. The belfry, the Tour aux Puces and the Moselle quays form the historic core, while the Uckange blast furnace (the listed U4) and the Fensch valley's steel heritage tell the iron saga. Two major airspace constraints: the prohibited zone of the Cattenom nuclear power plant, less than 10 km north-east, and the Luxembourg border — flying on the grand-ducal side means switching to Luxembourg's drone regulations.

The local economy combines cross-border services, multimodal logistics (Thionville-Illange port, Europort), residual steelmaking and brownfield regeneration. Drone missions: monitoring of logistics and housing projects in a border-pressured property market, structure inspection on the Moselle, industrial heritage, thermography.

Applicable regulations

Cleaning drones are heavy machines (10 to 25 kg with the loaded hose): they fall outside the open category for most jobs and operate in the specific category, under a scenario or an operational authorisation with SORA risk assessment, especially as they often fly in built-up areas right next to buildings. The ground area is always cordoned off and closed to the public during treatment (risk of falling water and spray). Environmental rules also apply: approved treatment products, controlled recovery or infiltration of runoff depending on the site, no direct discharge of biocides into storm drains. AlphaTango registration, pilot trained in tethered flight with payload, coordination with the building operator.

Frequently asked questions

Does drone cleaning damage tiles or panels?

No: pressure is adjusted to the substrate (low pressure on tiles and panels, never destructive high pressure) and the drone never touches the surface — unlike foot traffic, which cracks tiles.

What output gain can be expected after solar panel cleaning?

Depending on soiling (dust, pollen, bird droppings, agricultural or industrial deposits), observed gains range from 3 to 15% of output. A thermal inspection can be combined with cleaning to detect faulty modules.

Do water or power need to be cut during the work?

We bring our own water supply (tank and pumping station). For photovoltaic panels, shutting down the inverters during washing is recommended; we coordinate this with your plant operator.

Can this service be flown anywhere in Thionville?

Almost: Zone interdite de la centrale nucléaire de Cattenom; Frontière luxembourgeoise (réglementation drone différente); Emprises portuaires et logistiques d'Illange. Depending on the exact location, the pilot picks the right framework (open or specific category) and files the required declarations — included in the quote.
