A floor cleaning system may include a docking station to which an autonomous floor cleaning machine can dock between cleaning operations. The docking station can provide power to the autonomous floor cleaning machine to recharge the batteries of the machine when not in use. The docking station may also supply fresh cleaning fluid to the floor cleaning machine and remove collected waste from the machine. In practice, the floor cleaning machine may itself become dirty over repeated use, such as when cleaning greasy floor surfaces. Accordingly, the docking station may include flushing orifices to clean the floor cleaning machine itself, such as with a degreasing composition.
