Drone cleaning regulations define the legal and safety requirements that govern how exterior cleaning may be performed with an unmanned aircraft. This article explains how these frameworks differ between the European Union and the United States, and what an operator must satisfy in each market. For drone service operators adding facade cleaning, understanding drone cleaning regulations is the difference between a scalable, insurable business and one exposed to enforcement risk. WasherDrone (WD) supplies the system and the operational support that enable operators to meet these requirements — the company manufactures the equipment rather than performing the cleaning itself.
Drone cleaning regulations are the combined aviation and occupational-safety rules that determine where, how, and by whom a cleaning drone may be flown. They are not a single document but a stack: airspace authorization, operator competence, classification of the operation by risk, and insurance.
Two factors push facade cleaning into the regulated tier. First, the work takes place in built-up environments, often near people and property. Second, it involves a powered aircraft carrying fluid and operating at height. Both regulators therefore treat cleaning as a commercial drone operation that must be authorized before it begins — not an activity an operator can improvise on site.
The EU Approach: SORA and the Specific Category
In the European Union, most drone facade cleaning falls into the Specific category, where the operator must demonstrate acceptable risk before receiving an operational authorisation. The principal method for doing so is the Specific Operations Risk Assessment (SORA).
SORA is defined as a structured evaluation of ground risk and air risk that produces a SAIL (Specific Assurance and Integrity Level) and a set of Operational Safety Objectives the operator must meet. According to EASA, SORA 2.5 is the current reference methodology, with SORA 3.0 under development at JARUS, the international body whose work underpins the method. For operations that fit a pre-defined profile, two lighter pathways exist — the Standard Scenario (STS) and the Predefined Risk Assessment (PDRA) — which reduce the assessment burden without removing the authorisation requirement.
The US Approach: Part 107 Waivers and the Rise of Part 108
In the United States, drone cleaning is governed primarily by Part 107, with additional written justification required for any operation beyond the standard envelope. Part 107 applies to commercial drones under 25 kg (55 lb) and sets the baseline for most facade work.
The legal floor is 14 CFR §107.49: a pre-flight assessment of the operating environment, aircraft condition, and control links. It is a pilot responsibility rather than a documentation exercise. Any operation outside standard limits — flight over people, night operations, or beyond visual line of sight — moves the operator into a waiver regime under §107.200 that requires a written safety case. A new framework, Part 108, is reshaping this landscape. According to the FAA, the Part 108 Notice of Proposed Rulemaking was published on 7 August 2025 to replace the case-by-case waiver system with a performance-based structure covering operations up to 600 kg (1,320 lb). Enforcement stakes have risen in parallel: the FAA Reauthorization Act of 2024 raised civil penalty ceilings to $75,000 per violation.
EU vs. US Drone Cleaning Regulations Compared
The key difference between EU and US drone cleaning regulations is structural: the EU routes operators through a single risk-assessment pathway, while the US layers waivers and an emerging rule on top of a baseline regulation.
| Dimension | European Union | Amerika Birleşik Devletleri |
|---|---|---|
| Governing framework | SORA within the Specific category | Part 107 + §107.200 waivers; Part 108 (proposed) |
| Risk method | Ground + air risk → SAIL + Operational Safety Objectives | Pre-flight check (§107.49); written case for waivers |
| Weight scope | Case-by-case within Specific category | Part 107 under 25 kg (55 lb); Part 108 up to 600 kg (1,320 lb) |
| Approval unit | Operational authorisation per operation/scenario | Per-flight waiver → operational-area approval (Part 108) |
| Common root | JARUS SORA | JARUS-influenced (Part 108) |
The practical takeaway is convergence: both systems increasingly trace back to the same JARUS methodology, so an operator who builds compliance discipline in one market is better prepared for the other.
What This Means for Facade Cleaning Operators
Facade cleaning is typically a visual-line-of-sight (VLOS) operation, which keeps it within the more accessible tiers of both regulatory systems. The operator stands on the ground, the drone remains in sight, and the work does not require the beyond-visual-line-of-sight pathways that dominate delivery and inspection debates. Part 108 and BVLOS are therefore an adjacent frontier for the sector, not the standard route for a cleaning operation.
What operators do need is a documented, repeatable basis for authorisation: a classified operation, a competent remote pilot, and — in the EU — a completed SORA or a qualifying STS/PDRA. This is where system choice matters. WasherDrone supplies a platform engineered for these requirements and, as part of a SkyBase system purchase, provides SORA consultancy so operators can assemble their authorisation package rather than build it from scratch. Operators evaluating drone cleaning regulations for a new market can request a consultation through our contact form to scope the requirements that apply to them.
Sıkça Sorulan Sorular
Do you need a licence for drone cleaning?
Yes. In both the EU and the US, commercial drone cleaning requires a competent, registered operator and an authorisation appropriate to the operation. In the EU this typically means a Specific-category operational authorisation; in the US it means Part 107 certification plus any waiver the operation requires.
What is SORA in drone cleaning?
SORA, the Specific Operations Risk Assessment, is the EU methodology for demonstrating that a drone operation’s ground and air risks are acceptably controlled. It produces a SAIL level and a list of safety objectives the operator must meet to receive authorisation. For facade cleaning, it is the most common route to a compliant operation.
Does facade cleaning require BVLOS approval?
Usually not. Facade cleaning is normally conducted within visual line of sight, with the operator on the ground and the drone in view, so it falls outside the beyond-visual-line-of-sight rules. BVLOS frameworks such as the US Part 108 proposal are relevant to adjacent applications rather than to standard cleaning work.

WasherDrone does not perform commercial cleaning; it supplies the system and the operational support that enable operators to deliver compliant facade cleaning. Regulatory references should be verified against the current EASA and FAA publications before each operation.
