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 surface cleaning device comprises a cleaning head having a housing, a fluid tank configured to store fluid and be in fluid communication with the cleaning head, a cleaning pad coupled to the cleaning head and configured to remove debris from a surface, and a plurality of nozzles distributed along the cleaning pad, wherein the fluid tank is configured to release at least some of the fluid such that the released fluid flows through the plurality of nozzles onto the cleaning pad.

A cleaning roller for a cleaning appliance, in particular a wiping roller for a wet cleaning appliance, or a cleaning appliance having such a cleaning roller processes an area to be cleaned. The cleaning roller has a roller core that can rotate about a longitudinal axis and has a bearing for a drive shaft and a roller cover surrounding the roller core in the circumferential direction. The roller core, based on a cross section perpendicular to the longitudinal axis, has several spring elements formed beside one another in the circumferential direction of the cleaning roller, each of which extends from the bearing to the roller cover.

The present invention is a machine for treating a surface lying in an XY plane. The machine includes a body having a body plate, a working plate, a working pad, a drive assembly and an attachment assembly. The attachment assembly includes a plurality of flexible connectors directly connecting the body plate to the working plate. The working plate is located between the body plate and the XY plane. The drive assembly is connected to the working plate to drive the working plate with a working vibration in an oscillating pattern parallel to the XY plane.
