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.

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.

A laminated foam mop head which includes a foam block having a top surface, a bottom surface, and two side surfaces, a fabric material laminated to the bottom and side surfaces of the foam block, and a bracket attached to the top surface of the foam block such that the bottom and side surfaces of the foam block are drawn upward and inward to form a mop head having an elliptical shaped cross section and the top surface of the foam block is pushed inward and not exposed.

An insert for a mop includes a rail and a cleaning element at least partially disposed in an internal channel of the rail. Two protrusions are disposed on the body, each forming a leg connected to the body and a cylindrical wall defining an actuation bore connected to the leg. Each actuation bore is adapted to overlap a substantial portion of a tine, the tine being associated with a sponge mop having a hand lever that operates to pull the tine, the tine being disposed in the actuation bore and configured to impart a force onto the body through the actuation bore to pull the rail and the cleaning element through a set of rollers to wring out fluids that may be present in the cleaning element.

A cleaning device may include an extendable ergonomic handle having a fixed handle member and a telescoping handle member. The fixed handle member may be secured at its lower distal end to a mounting plate. The mounting plate may include two plate members connected by a hinge. A sponge may be removably connected to the mounting plate. The cleaning device may include a close and release mechanism housed within the handle members operatively connected to the hinged plate members. The close and release mechanism may be actuated to squeeze and wring out the sponge and thereafter return it to a cleaning configuration.

A self-wringing foam cotton mop includes a mop rod and a foam cotton head connected to a bottom end of the mop rod. A wringing frame is disposed on the mop rod. During mopping, the foam cotton head is separated from the wringing frame. A squeezing mechanism capable is disposed on the wringing frame. The position of the squeezing mechanism when the foam cotton head is moved up relative to the wringing frame is different from the position of the squeezing mechanism when the foam cotton head is moved down relative to the wringing frame, and a first amount of deformation generated by the foam cotton head during an upward movement of the foam cotton head relative to the wringing frame is greater than the second amount of deformation generated by the foam cotton head during a downward movement of the foam cotton head relative to the wringing frame.
