1. A self-propelled robot configured for movement over a trackless surface to be treated, the robot comprising:

  • a power supply;

    a traction mechanism configured to receive power from the power supply and move the robot over a trackless surface;

    a dispense mechanism adapted to controllably deposit a fluent material onto the trackless surface;

    a plurality of navigation sensors providing signals for enabling the robot to navigate over the trackless surface and around obstacles thereon;

    one or more deposition detectors adapted to detect the presence of the fluent material on the trackless surface and provide signals indicative thereof; and

    a control system configured to receive the signals from the navigation sensors and the one or more deposition detectors and operably dependent upon the signals to control the traction and dispense mechanisms.
