A handheld extraction cleaner includes a fluid delivery system and a recovery system including a suction nozzle, a recovery tank, and a suction source. The recovery tank has an auto-close feature that automatically seals an outlet of the tank when the recovery tank is mounted to a tank receiver of the extraction cleaner.

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 floor cleaner, comprising: a cleaning roller, a water channel, a clean water tank, a clean water supply system, a wastewater tank and an air pump. The water channel is configured to cover the cleaning roller with an airtight seal. The clean water tank, the clean water supply system and the water channel are in communication with each other, and the clean water supply system is configured to allow clean water in the clean water tank to flow to the water channel. The wastewater tank comprises a chamber for recovery and store of wastewater, and the chamber is provided with a wastewater inlet and an air extraction opening. The wastewater inlet and the water channel are in communication, and an inlet of the air pump and the air extraction opening of the wastewater tank are in communication.

A surface cleaning apparatus adapted for movement across a surface to be cleaned includes a recovery system and a fluid delivery system. The surface cleaning apparatus can have a rechargeable battery and a battery housing for the rechargeable battery. The surface cleaning apparatus has a self-cleaning mode of operation in which an unattended automatic cleanout cycle is executed.

A floor cleaning machine is provided, in particular a hand-guided and/or hand-held floor cleaning machine, including a support device, at least one cleaning roller arranged on the support device, capable of being driven in rotation and provided with a cleaning substrate, said cleaning substrate being made of a textile material; and at least one mouth towards the at least one cleaning roller that includes a first and a spaced second mouth wall having a mouth opening therebetween, wherein the first mouth wall is positioned above the second mouth wall relative to the direction of gravity, wherein the first and/or second mouth wall protrude(s) into the cleaning substrate of the at least one cleaning roller.
