Accordingly, unless otherwise indicated, features of the various embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concept of the present disclosure.

The use of cross-hatching and/or shading in the drawings is generally used to clarify the boundaries between adjacent components. As such, unless otherwise noted, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for a particular material, material property, size, proportion, commonality between the illustrated components and/or any other characteristic, attribute, property, etc., of a component. Further, in the drawings, the size and relative sizes of components may be exaggerated for clarity and/or descriptive purposes. While example embodiments may be practiced differently, the specific process sequence may be performed in a different order than that described. For example, two processes described consecutively may be performed substantially simultaneously or in reverse order to that described. In addition, like reference numerals denote like parts.

When an element is referred to as being "on" or "on," "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to" or "directly coupled to" another element, there are no intervening elements present. For purposes of this disclosure, the term "connected" may refer to physically, electrically, etc., and may or may not have intermediate components.

14. A surface cleaning apparatus as claimed in claim 10, characterised in that the supply tank is formed as a recess and such that the hollow standpipe of the recovery tank is located within the recess.

15. A surface cleaning apparatus as claimed in claim 8, wherein the rechargeable battery assembly is disposed to the frame by a battery support frame, the rechargeable battery assembly being located within the battery support frame.

16. A surface cleaning apparatus as claimed in claim 15, characterised in that the battery support is removably attached to the frame or at least a portion of the battery support is integrally formed with the frame.

17. A surface cleaning apparatus as claimed in claim 1, characterised in that part of the outer surface of the recovery tank is formed as part of the rear surface of the upstanding body and at least part of the outer surface of the supply tank is formed as part of the front surface of the upstanding body.

18. A surface cleaning apparatus as claimed in claim 1, characterised in that the upstanding body is pivotally connected to the cleaning base.

19. A surface cleaning apparatus as claimed in claim 18, wherein the suction port is in fluid communication with the selectively removable recovery tank via a conduit, wherein the conduit is a flexible conduit to accommodate pivotal movement of the upright body relative to the cleaning base.

20. A surface cleaning apparatus as claimed in claim 8, wherein the cleaning base further comprises first and second conductive structures connected to the rechargeable battery, the rechargeable battery assembly being charged via the first and/or second conductive structures when power is supplied to the first and/or second conductive structures, wherein the first and second conductive structures are located remotely from each other on the cleaning base.

21. A cleaning system, comprising:

surface cleaning apparatus according to any of claims 1-20, and

a cleaning tray including a tray body configured to be at least partially positioned below a cleaning base.

22. The cleaning system of claim 21, wherein the cleaning tray further comprises a first charging structure and a second charging structure, wherein the first charging structure is coupled to the first conductive structure of the cleaning base and the second charging structure is coupled to the second conductive structure of the cleaning base to charge a rechargeable battery assembly of the surface cleaning apparatus through the cleaning tray when the surface cleaning apparatus is docked to the cleaning tray.
