16. A spin mop system comprising:
a bucket assembly comprising:
a bucket including a top wall, a bottom wall, and a side wall extending between the top wall and the bottom wall, an axle member connected to the bottom wall, and a shelf positioned below the top wall; the axle member defining an axle axis,
wherein the bucket has an elongated shape that includes a length that is greater than a width, wherein the length extends from a first side to a second side opposite the first side, and the width extends from a third side to a fourth side opposite the third side,
a wringer basket rotatably engaged with the bucket along the axle axis, the wringer basket including a bottom wall, a perimeter wall extending upward from the bottom wall, a recess in the bottom wall that receives the axle member, and a plurality of wringer basket tabs extending inward from the perimeter wall, wherein the perimeter wall and the bottom wall have a plurality of openings that allow a liquid to pass through the plurality of openings; wherein the wringer basket is nearer the first side than the second side;
a cover secured to the shelf, wherein the cover includes a top surface, a central opening that is located over the wringer basket, and a splashguard that extends downward from the top surface;
wherein the splashguard of the cover is asymmetrical with respect to a plane that extends through the axle axis and a centerline of the bucket that extends in a direction from a center of the first side to a center of the second side; and
a spin mop structure comprising:
a handle assembly having a handle grip and a handle tube slidably engaged with a spiral member; the handle assembly defining a handle longitudinal axis;
the spiral member having a first end with an engaging member, a second end opposite the first end, and a central spiraled portion between the first end and the second end having a spiraled surface;
a swivel member pivotally attached to the engaging member of the spiral member along a first swivel axis; and
a mop base configured to releasably secure a mop head, wherein the mop base is pivotally attached to the swivel member along a second swivel axis, wherein the first swivel axis and the second swivel axis are generally perpendicular to each other; and
wherein when the mop base is received in the wringer basket of the bucket assembly, a movement of the handle assembly sliding along the spiral member causes the mop head to spin, which causes the wringer basket to rotate about the axle axis.
