## Executive read

### BLUF

March splits: a US consumer-protection filing about a Roomba wheel/H-bridge that does **not** allege injury, and a German lab test in which seven of eight robotic mowers cut a lying child-arm dummy. The live official fire file remains Husqvarna AWD. No March regulator recall was found.

### Key judgments

1. **[Assessment — High confidence]** *Toolis v. iRobot*, N.D. Ill. 1:22-cv-01290 (filed 10 March 2022), is a warranty / deceptive-practices case about Error 5 and a $59 wheel kit. It is **not** an injury or death docket.
2. **[Assessment — High confidence]** Stiftung Warentest *test* 4/2022 is the year’s first named-lab demonstration that current robotic-mower obstacle rules still fail a lying child-arm. No brand is tied to a March pediatric case.
3. **[Inference — Moderate confidence]** Genius 4.0’s expanded j7 “visual vocabulary” (clothes, towels) increases the training demand that later (December) becomes a leak story. That inference is not a March privacy incident.


### 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. Toolis v. iRobot — Error 5 / H-bridge, consumer protection, not injury

*Event / publication dates: alleged malfunction 8 February 2022; complaint filed 10 March 2022; Top Class Actions 15 March 2022*

**Product class.** Robot vacuums / mop combos

**Verified record — [Fact — B1]** *Toolis v. iRobot Corporation*, **1:22-cv-01290**, U.S. District Court for the Northern District of Illinois, Eastern Division, Judge Martha M. Pacold. Filed **10 March 2022** (Law.com “Who Got the Work,” 25 April 2022). Plaintiff Thomas W. Toolis bought a Roomba in 2018; on **8 February 2022** the left wheel stopped turning (Error 5); iRobot directed a **$59** wheel kit that did not restore function. The complaint alleges a defect in the “core processing unit,” specifically the **H-Bridge driver circuit**, that a wheel replacement cannot fix; alleges iRobot knew, kept selling, and charged for kits that do not remedy the failure; claims consumer-protection violations, deceptive practices, and implied-warranty breach. Relief sought includes damages, refunds, replacements and/or a recall, and an order stopping further sales. **No personal injury is alleged.** [Top Class Actions](https://topclassactions.com/lawsuit-settlements/consumer-products/appliances/irobot-class-action-claims-company-profits-from-defective-roomba-vacuums/), [classaction.org](https://www.classaction.org/blog/roomba-error-5-wheel-malfunction-caused-by-defect-class-action-alleges), [Law.com](https://www.law.com/2022/04/25/who-got-the-work-heres-who-worked-on-elon-musks-44b-purchase-of-twitter-and-more/). The PACER complaint PDF was not independently retrieved this pass (B1 via named case number + contemporaneous trade press).

**No March ruling, class certification, or settlement was found.**

**Threat landscape.** Drive-wheel / H-bridge failure bricks the kinematic. The harm in the pleading is money and a dead vacuum, not crush, fire, or laceration.

**Forum / community notes.**
- The complaint itself says the failure “has been well documented on the Internet.” Pre-existing RobotReviews H-bridge / Error 5 threads exist (e.g. Roomba 880 Error 5, 960 stiff-wheel). Those threads were not re-dated as March 2022 posts and are **C3** unless independently tied to this docket.

**Intelligence assessment.** [Assessment — High confidence] This is a consumer-protection filing, not an injury case — do not write it as one. [Uncertainty] Whether the H-bridge theory is design-wide or unit-specific is unadjudicated. Case disposition after March is not established in this window.

**Opportunity.** A ruling, a CPSC inquiry, or a manufacturer service bulletin that names the H-bridge would move this from pleading to Fact-on-the-hardware.

**LRRK relevance.** Control Fabric (drive-stage electronics). Passport: paid “fix” that does not fix. Watch: 1:22-cv-01290.

**Confidence.** High on case number, court, filing week, and non-injury character. Moderate on the H-bridge as the actual cause.

## 02. Stiftung Warentest: seven of eight robotic mowers cut a lying child-arm dummy

*Event / publication dates: Zeit/dpa 23 March 2022; *test* 4/2022 (listed 24 March 2022)*

**Product class.** Robotic lawn mowers

**Verified record — [Fact — B1]** Stiftung Warentest tested eight perimeter-wire, lithium robotic mowers declared for 450–800 m². Safety checks used a crawling-child-foot dummy approached from behind and a child-arm dummy reaching under the deck (flat and bent). **No model injured the child-foot dummy. Seven of eight injured the lying child-arm dummy.** No overall grade better than “befriedigend” (satisfactory); one model “mangelhaft” (poor). Two units restarted on schedule after the red emergency-stop was pressed; another restarted after a lift-sensor cutout — treated as safety downgrades. [Zeit](https://www.zeit.de/news/2022-03/23/maehroboter-test-offenbart-sicherheitsmaengel), [Stiftung Warentest footage note](https://www.test.de/presse/filmmaterial-5041724-0/video-690270373/), [testberichte.de citing *test* 4/2022, 24 March 2022](https://www.testberichte.de/p/worx-tests/m700-plus-wr167e-testbericht.html). Named models in the 4/2022 set (secondary tabulation): Husqvarna Automower 305, STIHL iMow RMI 422, Gardena Sileno minimo, Greenworks Optimow 4, Worx Landroid M700 Plus, Bosch Indego S+ 500, Einhell Freelexo 500 BT, Robomow RT700. **This is a lab test, not a March injury.** No brand-named March pediatric case was found.

**Threat landscape.** The sense function that treats a small object as grass still fails a child-shaped limb that is not a standing foot. Same class pattern as the 2018 Pertisau case (out of window). EN 50636-2-107 remains the product standard.

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

**Intelligence assessment.** [Assessment — High confidence] The child-arm failure is the lab counterpart of the hospital pattern, not a press one-off. [Inference — Moderate confidence] Emergency-stop restart is a separate, cheaper control failure than blade geometry. [Uncertainty] Which seven cut the arm is not independently tabulated from the paywalled *test* PDF this pass.

**Opportunity.** Opening *test* 4/2022 for the per-model injury table, and any brand-named 2022 pediatric case.

**LRRK relevance.** Sense / Move / Act. Lab: dummy-limb method. Watch: EN 50636 amendments.

**Confidence.** High on 7-of-8 arm / 0-of-8 foot and on the emergency-stop restart finding. Moderate on the exact eight-model list (secondary tabulation).

## 03. Genius 4.0 expands the j7 visual vocabulary — and adds a child/pet lock

*Event / publication dates: 17 March 2022*

**Product class.** Robot vacuums / mop combos

**Verified record — [Fact — A1 / B1]** iRobot began rolling out Genius 4.0 on 17 March 2022: Imprint Smart Mapping on Roomba i3/i3+, Siri shortcuts, room-specific preferences, Do Not Disturb, and a **Child & Pet Lock**. For j7/j7+, object avoidance expands from shoes, socks, cords, headphones, and solid pet waste to **clothing and towels**. iRobot: j-series has “already avoided 3 million objects” since the 2021 introduction. [iRobot](https://media.irobot.com/2022-03-17-iRobot-Releases-Genius-4-0-Home-Intelligence-Doubles-the-Intelligence-for-Roomba-R-i3-and-i3-Robot-Vacuums-and-More), [The Verge](https://www.theverge.com/2022/3/17/22982578/irobot-software-update-roomba-robot-vacuums).

**No March privacy incident or recall attaches to this update.**

**Threat landscape.** More classes to recognise means more labelled images. The lock is a control against unauthorised start, not against camera capture. Physical harm is not the story.

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

**Intelligence assessment.** [Assessment — High confidence] The update is real and camera-dependent. [Inference — Moderate confidence] Expanding j7 classes increases reliance on outsourced annotation (the December MIT TR fact is **not** a March Fact). [Uncertainty] Whether Child & Pet Lock is local or cloud-gated was not verified.

**Opportunity.** iRobot’s training-data and annotator contracts — later tested in December.

**LRRK relevance.** Sense and Control Fabric. Kestrel: object-class models. Watch: j7 camera pipeline.

**Confidence.** High on the 17 March feature list. Low on the training-data path this month.

## Forward indicators

1. Toolis docket activity (answer, motion to dismiss, or quiet death).
2. Per-model Stiftung Warentest arm-cut table from *test* 4/2022.
3. Any post-CPSC Husqvarna AWD fire, or OTA-completion figure.
4. First 2022 official floor-robot-vac thermal action (none through March).
5. Whether Genius 4.0’s new classes are trained on development units or retail opt-in images.

> **Collection integrity.** March official regulator recall: **none found** (CPSC/Health Canada/OPSS/Safety Gate/ACCC). Husqvarna AWD remains the live fire file. Toolis is consumer protection, not injury — that line is load-bearing. Stiftung Warentest is a lab test, not an accident. FAO Schwarz wooden robot excluded. No March forum threads independently opened.
