    AutonomyL3 confirmed
    ReadinessPromising progress strengthened
    ScoreScores unchanged

    No firmware update or hardware revision was announced in response. The next signal to watch is whether Gardena discloses RTK augmentation plans or publishes a GPS accuracy improvement roadmap.

    Impact on autonomy

    • Press coverage confirms GPS boundary drift in shaded conditions, consistent with manufacturer documentation
    • No autonomous recovery from GPS signal dropout documented in early evaluations
    • Boundary precision in open residential yards reported as functionally adequate for mowing purposes
    • Level III classification holds; canopy-shade failures align with documented conditional-autonomy scope

    Impact on readiness

    • Setup ease confirmed by multiple press sources as single-session process
    • Open-sky GPS requirement reinforced as genuine buyer constraint, not marketing fine print
    • No firmware update issued in first season to improve GPS accuracy
    • Owner reports on long-term reliability not yet available at this stage

    Press Evaluation Context

    Garden equipment and technology publications conducted first-season evaluations of the smart Sileno free 800 during the spring 2025 European mowing season, roughly 2-3 months after retail availability. Evaluations covered installation, GPS boundary setup via the GARDENA app, and mowing performance across yard types.

    GPS Boundary Performance

    Publications noted that GPS geofencing performed within acceptable margins in open residential yards: boundary excursions documented as occasional and self-correcting in clear-sky conditions. In yards with 30% or more overhead canopy cover from established trees, boundary drift was more frequent and required manual re-triggering of return-to-dock sequences. No firmware update was issued during the first season to address signal dropout behavior.

    Setup and App Experience

    Multiple press sources confirmed the single-session app-driven setup claim. The GARDENA app’s satellite map overlay and boundary drawing workflow described as intuitive for non-technical users. One European publication noted Bluetooth connectivity loss after extended winter storage, resolved by manual re-pairing.

    Husqvarna Group Context

    Gardena operates as a brand within the Husqvarna Group alongside the Husqvarna Automower line. The smart Sileno free 800 is the first GPS-only (non-RTK) wire-free mower shipped under the GARDENA brand; Husqvarna’s Automower EPOS platform offers RTK-based positioning at higher price points. No cross-brand feature transfer was announced during the period covered by this entry.
