A flexible hose for use with surface cleaning devices is disclosed that includes a support structure that allows a user to collapse and lock the same into a storage configuration, and then easily unlock the same using a relatively minor amount of force, e.g., a user-applied pulling force or mechanical force. Thus, in a general sense, a hose consistent with the present disclosure may include two relatively stable/steady-state configurations, namely a storage configuration and an in-use configuration. Thus, the hose allows a user to collapse and lock the hose when not in use, and to transition the hose to an in-use configuration to target various types of surfaces to clean including, for instance, floors, walls and ceilings which may be many feet (e.g., up to 5 feet or more) from the surface cleaning apparatus. 1. A hose for use with a surface cleaning apparatus , the hose comprising:{'b': '1', 'a support structure extending along a length of the hose, the support structure defining a first end to couple to a dirty air inlet of the surface cleaning apparatus and a second end for receiving dirty air, and wherein the support structure is at least partially surrounded by a layer of cover material to form a plurality of collapsible sections, each collapsible section defined by a flexible portion having an interior surface proximate a passageway of the hose for receiving dirty air and an exterior surface opposite the interior surface, the passageway having a radius of R; and'}{'b': 1', '1', '1, 'wherein the support structure is compressible to transition the hose into a storage configuration to shorten the overall length of the hose, and an in-use configuration to increase the overall length of the hose, and wherein each of the plurality of collapsible sections extend a distance D into the passageway in the storage configuration, the distance D being greater than half the radius R of the passageway.'}211. The surface cleaning apparatus of claim 1 , wherein the distance D ...
