Claim 0:
1. 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 the first reservoir is fixed 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 above a lower surface of the second reservoir to gravity feed liquid from the first reservoir downward directly into the second reservoir;
a flapper valve blocking the draining aperture of the first reservoir, wherein the flapper valve adjusts between a closed position that reduces liquid flowing through the draining aperture into the second reservoir and an open position that releases liquid from the first reservoir through the draining aperture into the second reservoir, wherein opening the flapper valve flushes the liquid in 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;
a pump that circulates liquid from the second reservoir to the first reservoir;
a first filter wherein the pump directs the liquid from the second reservoir through the first filter into the first reservoir to filter the liquid prior to pumping the liquid into the first reservoir.
