Preferably, the steam distributor is at least capable of distributing heated cleaning liquid steam to a surface to be cleaned located in front of the cleaning portion. Preferably, the thick film heater is located downstream of the first liquid reservoir and upstream of the vapour distributor.

Example two

The embodiment discloses a surface cleaning system, which comprises the surface cleaning device and a base station provided by the first embodiment.

The base station comprises a third liquid reservoir for storing a cleaning liquid to be dispensed to the first liquid reservoir; the base station cooperating with the surface cleaning apparatus to form a third fluid path communicating the third fluid reservoir with the first fluid reservoir when the base station is docked with the surface cleaning apparatus;

the base station is capable of dispensing heated cleaning liquid to the surface cleaning apparatus, i.e. the base station further comprises a heating device which heats cleaning liquid in the third liquid reservoir or cleaning liquid output by the third liquid reservoir, so that the base station sets up a first liquid reservoir which dispenses heated cleaning liquid to the surface cleaning apparatus. The heating means is located within the third liquid reservoir or in a third fluid passageway.

In one embodiment, the heating means is located downstream of said third liquid reservoir for increasing the heating efficiency, and the base station is adapted to replenish the first liquid reservoir with a quantity of heated cleaning liquid when the surface cleaning apparatus is docked with said base station.
