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.

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 floor cleaning machine includes a set of obstacle sensors that detect when the machine is approaching an obstacle. If the obstacle is less than a threshold distance away from the machine, the machine may output an alert and override the operator's command with a command to reduce the speed of the machine. If the obstacle is less than a minimum threshold distance away from the machine, the machine may come to a complete stop to prevent the collision.

Cleaning machine with collision prevention

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.
