         23 . The surface cleaning apparatus of  claim 22  wherein air wrap members extend inwardly from the air inlet end and are secured together at an axially inner end of the hair wrap. 
     
     
         24 . The surface cleaning apparatus of  claim 23  wherein the hair wrap members are planar. 
     
     
         25 . The surface cleaning apparatus of  claim 24  wherein the hair wrap members comprise an elastomeric material. 
     
     
         26 . The surface cleaning apparatus of  claim 25  wherein the air treatment chamber comprises a cyclone chamber. 
     
     
         27 . The surface cleaning apparatus of  claim 26  wherein the porous filtration member comprises a screen. 
     
     
         28 . The surface cleaning apparatus of  claim 25  wherein the porous filtration member comprises a screen. 
     
     
         29 . The surface cleaning apparatus of  claim 19  wherein the hair wrap comprises a plurality of hair wrap members. 
     
     
         30 . The surface cleaning apparatus of  claim 29  wherein the hair wrap members are planar. 
     
     
         31 . The surface cleaning apparatus of  claim 29  wherein the hair wrap members comprise an elastomeric material. 
     
     
         32 . The surface cleaning apparatus of  claim 31  wherein the air treatment chamber comprises a cyclone chamber. 
     
     
         33 . A surface cleaner comprising:
 (a) an air flow passage extending from a dirty air inlet to a clean air outlet;   (b) an air treatment chamber positioned in the air flow passage, the air treatment chamber comprising an air inlet at an air treatment air inlet end of the air treatment chamber, an opposed end longitudinally spaced from the air inlet end, a longitudinal axis defining a longitudinal direction and extending through the air inlet end and the opposed end, and an air treatment air outlet comprising an air treatment chamber outlet port;   (c) a physical filtration member positioned in the air treatment chamber upstream from the air treatment chamber outlet port, the physical filtration member comprising a longitudinal axis and an outer wall wherein at least a portion of the outer wall is porous;   (d) a cage defining a volume in which the physical filtration member is removably receivable, the cage comprising a plurality of elastomeric members whereby a size of the volume expands when the physical filtration member is inserted in the volume; and, (e) a suction motor positioned in the air flow passage downstream from the air treatment chamber.   
     
     
         34 . The surface cleaning apparatus of  claim 33  wherein the size of the volume reduces when the physical filtration member is removed from the volume. 
     
     
         35 . The surface cleaning apparatus of  claim 33  wherein the air treatment chamber comprises a cyclone chamber.
