    Worx Landroid M WR147 expands line with 4.0Ah battery and 0.25-acre coverage

    Worx released the WR147 SKU within the Landroid M 20V product line, increasing the battery from the original WR140 pack to a 4.0Ah configuration rated for 0.25-acre coverage.

    Full assessment
    AutonomyL2 confirmed
    ReadinessReady Now unchanged
    ScoreValue improved

    The hardware revision directly addresses documented owner complaints about insufficient runtime in yards near the coverage ceiling. Navigation architecture and wire-guided containment remain identical to the WR140.

    Impact on autonomy

    • Larger battery extends runtime, reducing mid-session dock returns on 0.25-acre yards
    • Boundary wire containment architecture unchanged; Level II classification unchanged
    • No new sensing, obstacle detection, or mapping capability introduced

    Impact on readiness

    • WR147 retail availability confirmed through major home improvement channels
    • Expanded battery reduces mid-session interruptions for yards at the upper coverage limit
    • WR140 battery pack remains compatible; existing owners can upgrade battery separately

    Claim check4 claims reviewed

    WR147 covers 1/4 acre
    Manufacturer specification lists 0.25 acre (approximately 10,890 sq ft) at rated runtime. Owner reports confirm coverage shortfall on densely thatched or irregularly shaped yards at this boundary.
    4.0Ah battery provides significantly extended runtime
    Manufacturer documentation cites extended runtime versus base WR140 configuration. Specific minute increase not published in available release notes; comparative owner reports describe reduction in mid-session dock returns on 0.25-acre properties.
    Same Landroid M platform, upgraded battery
    WR147 shares wire-guided navigation, blade system, dock, and app integration with WR140. Hardware revision confined to battery capacity. No autonomy architecture changes documented.
    20V battery compatible with other Worx tools
    Worx WA3553 battery series compatibility confirmed across Worx 20V platform. Interchangeability documented in manufacturer product listing and owner community reports.

    Bottom lineIncremental hardware revision addressing a documented runtime gap; navigation and autonomy capabilities unchanged.

    SKU Differentiation

    WR147 is a hardware revision within the Landroid M 20V line. It retains the WR140 chassis dimensions (20.1 in width, 4.3 in height, 15 in depth, 20.7 lb weight) and dock system. The primary change is battery capacity, documented in manufacturer product listings as a 4.0Ah pack versus the earlier configuration.

    Battery Specification

    20V Li-ion, 4.0Ah. Manufacturer rates WR147 runtime at 120 minutes for 0.25-acre coverage. Charge time 60 minutes per specification. Battery system uses Worx WA3553 series, cross-compatible with other Worx 20V platform tools per manufacturer documentation.

    Unchanged Architecture

    Boundary wire perimeter containment system unchanged. Pseudo-random path optimization algorithm unchanged. Rain sensor functionality unchanged. No new ultrasonic, LiDAR, or vision hardware added. IP54 splash protection rating unchanged. App integration through Worx Landroid app unchanged; no new connectivity modes added.

    Retail Positioning

    WR147 positioned at the upper end of the Landroid M 20V retail range; WR140 continues at lower price point. Both SKUs referenced in manufacturer product documentation and Canadian market listings accessed April 2026.

    Worx Landroid M 20V WR140 launches commercially in North America

    Worx released the Landroid M 20V (WR140) for retail purchase in North America, establishing wire-guided robotic mowing below the $1,000 threshold.

    AutonomyL2 confirmed
    ReadinessReady Now unchanged
    ScoreScores established

    The release brought autonomous mulching capability without extension cord or fuel management to the consumer market. Verify coverage claims against yard geometry and installation complexity before purchase commitment.

    Impact on autonomy

    • Boundary wire containment enables full mowing sessions without mid-session steering
    • Pseudo-random path optimization improves coverage over unguided random walk
    • Rain sensor triggers automatic dock return without user input

    Impact on readiness

    • Retail availability through major home improvement channels confirmed
    • In-box wire and dock hardware included; no separate installation kit required
    • Battery runtime documented at 90-120 minutes covering 0.25 acres per charge

    Claim check4 claims reviewed

    Set it and forget it" autonomous operation
    Manufacturer documentation requires 1-2 hours boundary wire installation before autonomous operation begins; ongoing wire integrity checks expected seasonally.
    Covers up to 0.25 acre per charge
    Manufacturer specification lists 0.25 acre coverage at rated 90-120 minute runtime. Coverage degrades on slopes or dense grass per owner reports.
    No maintenance required
    Manufacturer manual specifies monthly blade sharpening or replacement at 50-100 mowing hours; annual wire inspection also documented.
    Mulching eliminates grass clipping management
    Mulch discharge confirmed; fine clippings return to soil without bagging. Requires frequent mowing so clippings remain short enough to break down.

    Bottom lineCommercial availability confirmed; installation and maintenance overhead documented and above zero.

    Model Identity

    WR140 is the initial retail SKU for the Landroid M 20V line. Manufacturer specification sheet lists 20.1 in width, 4.3 in height, 15 in depth, 20.7 lb weight. Battery: 20V Li-ion, 80 Wh capacity, 120-minute runtime, 60-minute charge time. Noise level rated 67 dB.

    Navigation Architecture

    Boundary wire perimeter containment with pseudo-random path optimization. No LiDAR, no ultrasonic, no vision sensing. Perimeter detection via wire signal amplitude; rain sensor triggers dock return. Interior obstacles require manual wire loop installation during setup.

    Connectivity

    Wi-Fi and Bluetooth app control via Worx Landroid app. Session logs, battery telemetry, and mowing status transmitted to Worx cloud servers. Location data inferred from mower GPS timestamp metadata and boundary coordinates.

    Safety Certification

    Blade disengagement on dock contact; blade-stop delay under 3 seconds per manufacturer safety certification. IP54 splash protection rating; not rated for submersion.
