A moveable member is positioned in the air treatment chamber. A driving assembly is drivingly connected to the moveable member wherein the driving assembly is reconfigurable between a stored position and an operable position in which the driving assembly is operable to longitudinally translate the moveable member through at least a portion of the chamber. ## Claims ### Claim 1 A vacuum cleaner or extractor comprising: (a) an air flow path extending from a dirty air inlet to a clean air outlet; (b) an air treatment member having an air treatment chamber positioned in the air flow path, the air treatment chamber comprising an air treatment chamber air inlet, an air treatment chamber air outlet, an openable first end, a longitudinally spaced apart second end having the air treatment chamber air outlet and a longitudinally extending sidewall, wherein the air treatment chamber air outlet comprises a longitudinally extending porous member having a longitudinally extending porous sidewall; (c) a suction motor positioned in the air flow path upstream of the clean air outlet; (d) a moveable member positioned in the air treatment chamber, the moveable member comprising at least one of the porous member and a cleaning member positioned in the air treatment chamber between the sidewall of the air treatment chamber and the porous sidewall; and, (e) a driving assembly comprising a handle and a driving linkage wherein the driving assembly is reconfigurable between a stored position in which the moveable member is in a storage position and an operable position in which the moveable member is translatable through at least a portion of the chamber, wherein when the driving assembly is in the operable position, the driving linkage consisting of a single longitudinally extending driving member which is connected to the moveable member, whereby, when the driving assembly is in the operable position, the driving assembly is operable to longitudinally translate the moveable member through at least a portion of the chamber. ### Claim 2 (depends on 1) The vacuum cleaner or extractor of claim 1 wherein the extendable member comprises a rotatably mounted drive rod, the rotatably mounted drive rod has a longitudinal axis and the rotatably mounted drive rod is rotatably mounted about an axis that extends in a plane that is transverse to the longitudinal axis of the drive rod. ### Claim 3 (depends on 2) The vacuum cleaner or extractor of claim 2 wherein the driving linkage comprises a longitudinally translatable drive rod and the rotatably mounted drive rod is rotatably mounted to the longitudinally translatable drive rod. ### Claim 4 (depends on 1) The vacuum cleaner or extractor of claim 1 wherein a portion of the driving linkage is exterior to the air treatment chamber and in the stored position, the portion of the driving linkage is recessed against a portion of the vacuum cleaner or extractor. ### Claim 5 (depends on 4) The vacuum cleaner or extractor of claim 4 wherein, in the stored position, the portion of the driving linkage is coextensive with a portion of the air treatment member. ### Claim 6 (depends on 1) The vacuum cleaner or extractor of claim 1 wherein the handle is rotatably mounted and in the stored position, the handle is recessed against a portion of the vacuum cleaner or extractor and in the operable position the handle is positioned away from the portion of the vacuum cleaner or extractor. ### Claim 7 (depends on 6) The vacuum cleaner or extractor of claim 6 wherein, in the stored position, the handle abuts the portion of the vacuum cleaner or extractor. ### Claim 8 (depends on 6) The vacuum cleaner or extractor of claim 6 wherein the driving linkage comprises a longitudinally extending drive rod having a drive rod axis and the handle is rotatable about the drive rod axis. ### Claim 9 (depends on 1) The vacuum cleaner or extractor of claim 1 further comprising a stop member operably engageable with the driving assembly to inhibit the driving assembly moving to the operable position. ### Claim 10 (depends on 1) The vacuum cleaner or extractor of claim 1 wherein the moveable member is moveable from an operating position in which the moveable member is positioned towards the second end and a cleaned position in which the moveable member is translated longitudinally away from the second end. ### Claim 11 (depends on 10) The vacuum cleaner or extractor of claim 10 wherein in the cleaned position, at least a portion of the moveable member is exterior of the air treatment chamber. ### Claim 12 (depends on 1) The vacuum cleaner or extractor of claim 1 wherein the moveable member comprises the cleaning member and the cleaning member is moveable from an operating position in which the cleaning member abuts the second end and a cleaned position in which the moveable member is translated longitudinally away from the second end. ### Claim 13 (depends on 1) The vacuum cleaner or extractor of claim 1 wherein the cleaning member comprises an annular member. ### Claim 14 (depends on 1) The vacuum cleaner or extractor of claim 1 wherein the handle has a first end and an opposed second end and the driving linkage is connected to the handle at only the first end of the handle. ### Claim 15 (depends on 1) The vacuum cleaner or extractor of claim 1 wherein the driving linkage comprises an extendable member wherein, in the stored position, the extendable member is in a contracted configuration and, in the operable position, the extendable member is in an extended configuration in which the handle is operable to longitudinally translate the moveable member through at least a portion of the chamber. ### Claim 16 (depends on 15) The vacuum cleaner or extractor of claim 15 wherein the driving linkage is drivingly connected to the moveable member when the extendable member is in the contracted configuration. ### Claim 17 (depends on 15) The vacuum cleaner or extractor of claim 15 wherein the extendable member comprises a telescoping drive rod. ### Claim 18 (depends on 15) The vacuum cleaner or extractor of claim 15 wherein the extendable member is exterior to the air treatment chamber and in the contracted configuration, the extendable member is recessed against a portion of the vacuum cleaner or extractor. ### Claim 19 (depends on 18) The vacuum cleaner or extractor of claim 18 wherein, in the contracted configuration, the extendable member is coextensive with a portion of the air treatment member. ### Claim 20 (depends on 15) The vacuum cleaner or extractor of claim 15 wherein the extendable member has the handle and, in the extended configuration, the handle is longitudinally spaced from the first and second ends of the air treatment chamber.
