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.

Safety module for a floor cleaning unit

A cleaning device may include a solution tank configured to store cleaning solution. The device delivers the cleaning solution from a pump discharge of the cleaning device to a flow meter. The device initiates a priming mode by opening a first valve associated with a bypass line of the device, closing a second valve associated with a cleaning head of the cleaning device, and delivering the cleaning solution from a discharge of the flow meter to the inlet of the solution tank through the bypass line. When the device is primed, it initiates cleaning by closing the first valve associated with the bypass line, opening the second valve associated with the cleaning head, and delivering the cleaning solution to the cleaning head.

Cleaning device with single tank recycling system

A method of cleaning an area using an automatic cleaning device may include receiving, from a video camera, information associated with an edge located on a surface, determining, by an automatic cleaning device, a position of the automatic cleaning device on the surface relative to the edge and using the received information to move the automatic cleaning device from the determined position along a path so that the automatic cleaning device cleans the surface along the path. The path may be substantially parallel to the edge, and the edge may be located a distance from a reference point on the automatic cleaning device during movement of the automatic cleaning device.

Methods and systems for movement of an automatic cleaning device using video signal

A cleaning device may include a solution tank configured to store cleaning solution. The solution tank may include an inlet and an outlet. The cleaning device may include at least one discharge line filter in fluid communication with the solution tank and a pump having a pump intake and a pump discharge. The pump may be configured to direct cleaning solution from the solution tank outlet through the at least one discharge line filter. The cleaning device may include a cleaning head in fluid communication with the pump discharge and a bypass line in fluid communication with the pump discharge and the inlet. The bypass line may be configured to divert cleaning solution received from the pump discharge away from the cleaning head and toward the solution tank.

A method of navigating an area using a mobile robotic device may include receiving, from a video camera, information associated with an edge located on a surface, determining, by a mobile robotic device, a position of the mobile robotic device on the surface relative to the edge and using the received information to move the mobile robotic device from the determined position along a path. The path may be substantially parallel to the edge, and may be located a distance from a reference point on the mobile robotic device during movement of the mobile robotic device.
