Abstract: A mop bucket includes a fluid reservoir portion and a wringing portion. The fluid reservoir portion can hold fluid. The wringing portion includes a first wringing member and a second wringing member, which is moveable toward the first wringing member to wring fluid from a mop. The wringing portion further includes a linkage configured to move the second wringing member in response to actuation of a wringer handle. The linkage includes a first link extending from and pivotable relative to the second wringing member and a second link connected to the first link and having an axis that is fixed at an angle relative to an axis of the wringer handle. The second wringing member can include an integrally formed shaft about which the second wringing member rotates. A first retaining surface of the first wringing member can engage the shaft to hold the shaft at a pivot axis.

Abstract: A cleaning tool comprises a soft, flexible body. A resilient backbone is located inside of the flexible body. The backbone may be insert molded in the body. The backbone may be formed of a plurality of branches where the branches extend from a center core to the edge of the body. The backbone may be formed with an arched shape in its undeformed state such that the body has an arched shape in its undeformed state and a cleaning surface of the body has a concave shape such that pressure may be applied to the body opposite the cleaning surface to flatten out the body. The body may have a first straight edge and an opposite convex edge where the concave edge may terminate at a corner having an acute included angle. The backbone may be pivotably connected to a handle.
