Abstract
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.
