3 . The hand vacuum cleaner of claim 2 wherein at least 75% of the length is positioned in the pistol grip handle.

4 . The hand vacuum cleaner of claim 1 further comprising an energy storage member housing provided at an end of the pistol grip handle.

5 . The hand vacuum cleaner of claim 4 wherein air flows over or through the energy storage member housing at a location upstream of the clean air outlet.

6 . The hand vacuum cleaner of claim 4 further comprising a post-motor filter housing and, when the hand vacuum cleaner is oriented with the dirty air inlet above the pistol grip handle, the post-motor filter housing is located at a lower end of the pistol grip handle or below the lower end of the pistol grip handle.

7 . The hand vacuum cleaner of claim 1 wherein the dirty air inlet is located at an upper end of the hand vacuum cleaner and an energy storage member is provided at a lower end of the pistol grip handle.

8 . The hand vacuum cleaner of claim 1 further comprising a pre-motor filter positioned in a pre-motor filter housing downstream of the air treatment member, the longitudinal axis extends through the air treatment member and the pre-motor filter housing, and, when the hand vacuum cleaner is oriented with the dirty air inlet above the pistol grip handle, the pistol grip handle extends downwardly from a lower surface of the hand vacuum cleaner and an energy storage member is provided at a lower end of the pistol grip handle.

9 . The hand vacuum cleaner of claim 8 further comprising a main body, the main body comprising the pre-motor filter housing and the pistol grip handle extends downwardly from a lower surface of the main body.

10 . The hand vacuum cleaner of claim 8 wherein at least a portion of the air treatment member is moveable relative to the main body.

11 . The hand vacuum cleaner of claim 8 wherein the air treatment member is removably mounted to the main body.

12 . The hand vacuum cleaner of claim 1 wherein, when the hand vacuum cleaner is oriented with the dirty air inlet above the pistol grip handle, the clean air outlet is at a lower end of the pistol grip handle or below the lower end of the pistol grip handle.

13 . The hand vacuum cleaner of claim 1 wherein the longitudinal axis extends through the pistol grip handle.

14 . The hand vacuum cleaner of claim 13 wherein the pistol grip handle is provided at the rear end of the hand vacuum cleaner and a finger grip area is provided forward of the pistol grip handle and rearward of the air treatment member.

15 . The hand vacuum cleaner of claim 13 further comprising an energy storage member housing provided at an end of the pistol grip handle.

16 . The hand vacuum cleaner of claim 15 wherein air flows over or through the energy storage member housing at a location upstream of the clean air outlet.

17 . The hand vacuum cleaner of claim 13 further comprising a pre-motor filter positioned in a pre-motor filter housing downstream of the air treatment member, the longitudinal axis extends through the air treatment member and the pre-motor filter housing, and, when the hand vacuum cleaner is oriented with the dirty air inlet above the pistol grip handle, an energy storage member is provided at a lower end of the pistol grip handle.

18 . The hand vacuum cleaner of claim 13 further comprising a post-motor filter housing and, when the hand vacuum cleaner is oriented with the dirty air inlet above the pistol grip handle, the post-motor filter housing is located at a lower end of the pistol grip handle or below the lower end of the pistol grip handle.

19 . The hand vacuum cleaner of claim 13 wherein the dirty air inlet is located at an upper end of the hand vacuum cleaner and an energy storage member is provided at a lower end of the pistol grip handle.

20 . The hand vacuum cleaner of claim 13 further comprising a main body, the main body comprising the pre-motor filter housing and the pistol grip handle is located rearward of the main body.
