A sponge roller, a cleaning roller assembly, and a floor cleaner. The sponge roller includes an outer layer and an inner layer. The outer layer is sleeved on the inner layer; the inner layer is made of non-absorbent sponge, and the outer layer is made of absorbent sponge. The sponge roller can be made with a large thickness, thus improving the cleaning capacity of the cleaner. The water is mainly stored in the outer layer, so it can be squeezed out without the exertion of much more external force, and thus the resistance against the rotation of the sponge roller is negligible, thus saving the energy consumption.

Flat mops and self-wringing flat mops can include a wringing configuration for applying a linear wringing motion to a mop head assembly, such as may occur along an axis coaxial with a handle. Four-point self wringing configurations may include four-point guide surfaces and/or four-point pressure points for wringing a mop head assembly.

The present invention relates to a hybrid roller mop having a handle, a mop head with a slot defined therein, a cleaning member and a lever mechanism. The mop head can be connected to the handle at one end and have rollers connected at the other end and spaced by the slot defined in the mop head. The cleaning member and lever mechanism can be connected together by a linkage disposed in the mop handle. The lever mechanism can be configured for raising and lowering the cleaning member between the rollers and into the slot of the mop head in order to wring out excess liquid from the mop. The cleaning member can have a generally inverted V shape that can lie flat against a floor or similar surface and can be folded into a compressed position when pulled between the rollers and into the slot of the mop head.

A mechanism by which the mop of a sponge roller mop is released without a user having to touch a dirty mop so that the sponge can be released and replaced with a clean sponge, including a sponge pin molded onto the brace which retains the sponge. The mechanism includes a transverse section with a movable hole through which the crown from the sponge pin is inserted. The wall is moved by a transverse spring force so that the wall from the opening of the trigger mechanism is placed between the crown and a lower section of the sponge pin to thereby retain the crown within the rod retaining mechanism. When a pushbutton is pushed transversely, it overcomes the spring force so that the crown is released and a downward force from the vertical compression spring forces the crown downwardly and out of the trigger mechanism, thereby releasing the sponge.
