If a robotic lawn mower is heading into the EU, EN 50636-2-107 is the standard that determines whether it can legally carry a CE mark for this product category. This guide breaks down what the standard covers, how it fits alongside EN 60335-1 and the Machinery Directive, and what buyers should confirm before a shipment leaves the factory.
EN 50636-2-107 is the EU safety standard specific to robotic lawn mowers. It does not stand alone — it supplements EN 60335-1, the general safety standard that covers household and similar electrical appliances. A robotic mower is still an electrical appliance in the EN 60335-1 sense, but it also introduces risks that a generic appliance standard was never written to address: it operates outdoors, unattended, in a garden that may contain people, pets, uneven terrain and a rotating blade close to ground level.
That combination of autonomous operation and an exposed cutting system is why regulators treated this as a distinct product category rather than folding it into the existing appliance standard. EN 50636-2-107 adds the mower-specific test protocols — obstacle detection, contact force limits, blade energy assessment and thrown-object containment — on top of the baseline electrical and mechanical safety requirements that EN 60335-1 already sets for any household appliance.
CE marking for a robotic mower is not granted on the strength of EN 50636-2-107 alone. The Machinery Directive 2006/42/EC is the legal instrument that requires a manufacturer or importer to compile technical documentation — the Annex VII technical file — and complete a conformity assessment before the CE mark can be applied. EN 50636-2-107 is the technical reference that the mower-specific portion of that file is built against.
Two other requirements usually travel alongside it. The Low Voltage Directive (LVD) covers the electrical safety of the battery and charging system, and RoHS restricts hazardous substances in the electronics. A mower shipped to the EU typically needs all three lined up — EN 50636-2-107 compliance feeding the Machinery Directive file, plus LVD and RoHS coverage for the electrical and materials side. None of these is a substitute for the others, and a supplier that can only produce one of them has not completed the full picture.
The standard's content is more specific than "the mower should be safe." It defines measurable test criteria that a model either passes or does not. The table below summarizes the areas most relevant to a buyer evaluating a supplier's documentation, without reproducing the full text of the standard.
| Requirement Area | What It Covers | Why It Matters to Buyers |
|---|---|---|
| Active obstacle sensing | In autonomous mode, sensors must actively detect obstacles across the directions of travel | Reduces the risk of collision with people, pets or objects left in the garden |
| Contact force limits | Force on impact capped at ≤260N (and >50N) within 0.5 seconds of contact, then ≤130N afterward | Defines the physical safety margin if the mower contacts a person or object |
| Blade/cutting system kinetic energy (Annex AA) | Assesses the energy of the rotating cutting system and the containment required around it | Tied directly to injury risk from the blade itself |
| Thrown-object containment (Annexes BB/CC/DD) | Tests whether debris thrown by the blade stays contained within the housing | Addresses a common real-world incident type for any rotary-blade mower |
In practice, compliance is a paper trail, not a sticker. It consists of a technical file referencing the applicable clauses of EN 50636-2-107, a test report from the body that ran the assessment, and a declaration of conformity tying that report to a specific model and, usually, a specific production run. None of these documents cover a factory's entire catalog by default — a test report for one wire-free navigation model does not automatically extend to a different commercial zero-turn model from the same factory.
This is the detail that gets lost in a quick sourcing conversation. A supplier may genuinely hold EN 50636-2-107 documentation for one SKU while having none for another in the same product line. Buyers who ask "are you EN 50636-2-107 certified" as a yes/no question tend to get a confident yes that does not hold up once you ask which SKU the paperwork actually names.
MowHub organizes robotic lawn mower production across verified partner factories rather than operating a single production line, so the practical question is how documentation gets matched to an order correctly. The process starts with the product category: an autonomous wire-free navigation model is assessed against the full EN 50636-2-107 suite, while a remote-controlled model has a different applicable test profile.
From there, the relevant partner factory's technical file and test reports are checked against the exact SKU in the quote, not the factory's general reputation. This is confirmed per order, because the documentation that is correct for one model in a catalog is not automatically correct for another. The goal is matching the right paperwork to the right unit before it ships, not making a blanket compliance claim across an entire product range.
