Abstract
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.
