Surface cleaning apparatus

Abstract

A portable surface cleaning apparatus has a main body and air treatment member assembly is removably mounted to the main body. The air treatment member assembly air outlet and/or the suction motor inlet end is provided at the lower end of the air treatment member assembly when the surface cleaning apparatus is located on a floor and a pre-motor filter underlies the air treatment member assembly and/or the suction motor.

1 .- 20 . (canceled) 
     
     
         21 . A surface cleaning apparatus comprising:
 (a) an air flow path extending from a dirty fluid inlet to a clean air outlet;   (b) an air treatment chamber positioned in the air flow path, the air treatment chamber having an upper end and an opposed lower end, wherein an air treatment chamber axis extends between the upper and lower ends, wherein an air treatment chamber air inlet and an air treatment chamber air outlet are provided at a common end of the air treatment chamber;   (c) a pre-motor filter positioned in the air flow path downstream from the air treatment chamber, the pre-motor filter having an upstream surface and a downstream surface; and   (d) a suction motor positioned in the air flow path downstream from the pre-motor filter, wherein the suction motor has a motor axis of rotation,   wherein the pre-motor filter is laterally spaced from the air treatment chamber, and   wherein the suction motor is also laterally spaced from the air treatment chamber, and   wherein an accessory cleaning tool is mountable laterally from the suction motor and, when the accessory cleaning tool is mounted to the surface cleaning apparatus, a plane that is transverse to the air treatment chamber axis extends through the air treatment chamber, the suction motor and the accessory cleaning tool.   
     
     
         22 . The surface cleaning apparatus of  claim 21  wherein the air treatment chamber axis and the motor axis of rotation are parallel. 
     
     
         23 . The surface cleaning apparatus of  claim 22  wherein air travels through the air treatment chamber air outlet in a flow direction and the flow direction is parallel to the air treatment chamber axis. 
     
     
         24 . The surface cleaning apparatus of  claim 21  wherein a carry handle is provided on an upper end of the surface cleaning apparatus and, when the surface cleaning apparatus is oriented with the carry handle at the upper end of the surface cleaning apparatus, an inlet end of the suction motor faces downwardly. 
     
     
         25 . The surface cleaning apparatus of  claim 21  further comprising a carry handle having a hand grip portion wherein the handgrip portion overlies the suction motor and the air treatment chamber. 
     
     
         26 . The surface cleaning apparatus of  claim 25  wherein a first end of the handle is secured to an upper surface of the surface cleaning apparatus at a location that overlies the air treatment chamber and a second end of the handle is secured to the upper surface of the surface cleaning apparatus at a location that overlies the suction motor. 
     
     
         27 . The surface cleaning apparatus of  claim 25  wherein the air treatment chamber axis and the motor axis of rotation are parallel. 
     
     
         28 . The surface cleaning apparatus of  claim 27  wherein air travels through the air treatment chamber air outlet in a flow direction and the flow direction is parallel to the air treatment chamber axis. 
     
     
         29 . The surface cleaning apparatus of  claim 25  wherein the pre-motor filter is removably positionable in a pre-motor filter housing and the motor axis of rotation extends through the pre-motor filter housing. 
     
     
         30 . The surface cleaning apparatus of  claim 21  wherein, when the accessory cleaning tool is mounted to the surface cleaning apparatus, the suction motor is located between the air treatment member and the accessory cleaning tool. 
     
     
         31 . The surface cleaning apparatus of  claim 21  wherein, when the accessory cleaning tool is mounted to the surface cleaning apparatus, the clean air outlet faces the accessory cleaning tool. 
     
     
         32 . The surface cleaning apparatus of  claim 21  wherein the pre-motor filter is removably positionable in a pre-motor filter housing and the motor axis of rotation extends through the pre-motor filter housing.
