Claim 10:
11. A filtration system in a mopping system for filtering a liquid for cleaning a floor, the filtration system comprising:
a first reservoir for storing the liquid;
a second reservoir that receives liquid from the first reservoir wherein a lower interior surface of the first reservoir is positioned above a lower interior surface of the second reservoir;
wherein the first reservoir is secured in a fixed position in relation to the second reservoir;
a draining aperture within the first reservoir that directs the liquid from the first reservoir to the second reservoir wherein the draining aperture is secured vertically above the lower interior surface of the second reservoir to feed liquid from the first reservoir downward into the second reservoir without pumping the liquid from the first reservoir to the second reservoir;
a pump that circulates liquid from the second reservoir to the first reservoir wherein the pump takes in liquid from the second reservoir and directs the liquid to the first reservoir;
a first filter wherein the pump directs liquid from the second reservoir through the first filter to the first reservoir before releasing the liquid from the second reservoir into the first reservoir; and
a flapper valve blocking the draining aperture of the first reservoir wherein opening the flapper valve gravity feeds the liquid from the first reservoir, wherein opening the flapper valve flushes the liquid from the first reservoir through the draining aperture into the second reservoir;
an attachment post secured to the first reservoir exterior of the draining aperture, wherein the flapper valve attaches to the attachment post, wherein the flapper valve pivots in relation to the attachment post to open and close the draining aperture;
wherein the flapper valve automatically closes upon flushing sufficient liquid from the first reservoir through the draining aperture into the second reservoir.
