    Remote diagnostics for maintenance alerts
    Maintenance alerts not confirmed for the Sigma; the higher-tier Dolphin Nautilus CC Plus documents more extensive app diagnostics; feature parity not established

    Bottom lineThe app update adds scheduling convenience without changing the robot's autonomous coverage behavior or classification standing.

    Technical notes4 sections
    App Update Scope

    Maytronics extended MyDolphin Plus connectivity to the Sigma, documenting weekly cycle scheduling and remote start. The app communicates with the Sigma’s onboard Wi-Fi module via the MyDolphin Plus cloud infrastructure. Cycle length selection (2-hour and 3-hour documented modes) is accessible through the app interface.

    Navigation Architecture Unchanged

    The app update is a connectivity layer addition. The gyroscopic mapping system and programmed floor-wall-waterline path sequence operate identically whether the robot is dispatched from the app or from the onboard power supply controls. No path optimization or adaptive coverage changes are documented in this update.

    Connectivity Requirements

    The Sigma’s power supply connects to a 2.4 GHz Wi-Fi network for app pairing. 5 GHz band pairing is not supported. MyDolphin Plus app is available for iOS and Android. App operation is additive; the robot functions without app pairing for owners who prefer manual cycle start.

    Feature Parity Notes

    Remote diagnostics and live cycle-status tracking are documented on higher-tier Maytronics models. For the Sigma, the app update specifically covers scheduling and remote start; diagnostic scope remains narrower than the Dolphin Premier and Dolphin Triton tiers.
