## Executive read

### BLUF

CENELEC approved amendment A3 to the European robotic-mower safety standard on 22 March. That is a control rewrite, not an injury file. The Clean Base Canada dock recall remains the only official consumer-robot safety action still live. No CPSC, Health Canada, OPSS, or Safety Gate consumer-robot recall was found this month.

### Key judgments

1. **[Assessment — High confidence]** EN 50636-2-107:2015/A3:2021 was approved 22 March 2021 and will rewrite obstruction, tilt/lift, working-area, and restart rules for robotic battery mowers ≤75 V d.c. Publication follows in April.
2. **[Assessment — High confidence]** ANSI/OPEI 60335-2-107-2019 remains a 2019 document. No March 2021 US adoption or enforcement item was found.
3. **[Assessment — High confidence]** Clean Base RA-74597 is still live and still Canada-only.


### Analytic labels
- **Fact** — verified reporting or primary record
- **Assessment** — analytic judgment
- **Inference** — reasoned but not directly observed
- **Uncertainty** — unresolved information gap

### Source grades
- **A1** — authoritative primary record / directly confirmed
- **B1–B2** — generally reliable and corroborated
- **C3** — useful but requires caution (typical for forums)

## 01. CENELEC approves EN 50636-2-107 A3

*Event / publication dates: approved by CENELEC 22 March 2021; dated April 2021 as EN; catalog publication 15 April 2021 (next month)*

**Product class.** Robotic lawn mowers

**Verified record — [Fact — A1 / B1]** Amendment A3 to EN 50636-2-107:2015 was approved by CENELEC on 22 March 2021. The amendment text (opened via catalog extract) modifies moisture resistance, stability and mechanical hazards, mechanical strength, construction (working-area boundary, obstruction sensors, disabling devices), components, and heat/fire, and it rewrites the foot-probe and obstruction-sensor figures. Obstruction sensors in automatic mode must act in all travel directions except narrow exceptions; traction stop within \(t = D/v\); cutting-means stop if the sensor does not clear in 3 s. National implementation date (dop) 22 March 2022; conflicting standards withdrawn (dow) 22 March 2024. A3 aligns the EN with IEC 60335-2-107:2017+A1:2020. [iteh / CENELEC catalog extract](https://standards.iteh.ai/catalog/standards/clc/6099800d-ec9b-4c54-9858-ccbcddbe521c/en-50636-2-107-2015-a3-2021). Official Journal citation of the harmonized standard is later (13 April 2022) and is out of this window.

**Threat landscape.** The standard is the control that hospitals in German-speaking Europe have already shown can fail on a crawling child (2018 Pertisau is out of window and is not recounted as a March Fact). A3 is paper. It is not an incident.

**Forum / community notes.**
- none found.

**Intelligence assessment.** [Assessment — High confidence] March’s event is approval, not publication and not an injury. [Inference — Moderate confidence] The obstruction-sensor timing rewrite exists because the 2015/A2 rules were not enough. [Uncertainty] Whether A3 closes the crawling-child gap is not established from the amendment text alone.

**Opportunity.** April publication and the first brand-named pediatric case after A3.

**LRRK relevance.** Lab / Watch: obstruction-sensor timing. Sense / Move / Act.

**Confidence.** High on the 22 March approval date and on the obstruction-sensor sentences in the opened extract. Moderate on whether A3 is sufficient.

## 02. Clean Base still live

*Event / publication dates: Health Canada RA-74597, 21 December 2020; still posted*

**Product class.** Robot vacuums / mop combos (dock electrical)

**Verified record — [Fact — A1]** Unchanged: liquid → dock PCB short; dock not robot; no Canada incidents as of 8 December 2020; 11,971 units. [Health Canada](https://recalls-rappels.canada.ca/en/alert-recall/irobot-clean-base-roombar-i7-robot-vacuum-recalled-due-electrical-hazard). No March update. No CPSC page.

**Threat landscape.** Unchanged.

**Forum / community notes.**
- none found.

**Intelligence assessment.** [Assessment — High confidence] Still the only official North American consumer-robot electrical action at cutoff.

**Opportunity.** Dated incident update or CPSC twin.

**LRRK relevance.** Lab / Watch.

**Confidence.** High on the page.

## Forward indicators

1. EN 50636-2-107 A3 publication (expected April) and Official Journal citation (later).
2. Any 2021 brand-named robotic-mower pediatric case.
3. Clean Base still-live status and any CPSC twin.
4. JetBot / Moxie actual shipments with a dated primary.
5. First 2021 official consumer-robot recall.

> **Collection integrity.** Honest signal count this month: **2**. Roborock S7 US sale (24 March, $649) was seen and not graduated — product announcement, no harm/trust primary. Moxie first-batch shipping is alleged in a 25 April Fortune piece and is held for April. Killed: ANSI/OPEI 60335-2-107-2019 as a 2021 adoption item; Certified 2-in-1 electric mowers (Health Canada 30 June 2021) — walk-behind, not robotic. No March CPSC/OPSS/Safety Gate consumer-robot recall found. Forum empty.
