Abstract
A cleaning unit for cleaning floors comprising a drivetrain, a main controller, a safety module, and one or more cleaning aggregates for cleaning a floor upon which the cleaning unit moves. The main controller may operate the cleaning unit in one of an autonomous mode in which cleaning unit autonomously navigates while cleaning the floor or a manual mode in which the cleaning unit is maneuverable under an applied external force while cleaning the floor. The safety module may be responsive to a plurality of safety inputs such that if a safety input indicates an unsafe condition, the safety module initiates a lockout to stop movement by the cleaning unit. In the autonomous mode, the safety module may be responsive to a first set of safety inputs and in the manual operating mode, the safety module may be responsive to a second set of safety inputs.
