- a cleaning head on one end of said handle;
- a trigger mounted within a slot in said handle;
- a door connected to said handle; and
- a switch mounted within said handle slidable to a first position wherein a first end of said switch overlaps said trigger slot to impede depression of said trigger and a second end of said switch opposite said first end is disengaged from said door to permit opening of said door, a second position wherein said first end of said switch overlaps said trigger slot to impede depression of said trigger and said second end of said switch is engaged with said door to impede opening of said door, and a third position wherein said second end of said switch is engaged with said door to impede opening of said door and said first end of said switch is substantially clear of said trigger slot to permit depression of said trigger.
- 3. A cleaning wand, as recited in claim 2, wherein said switch comprises a single button extending outward from said handle through a button slot in said handle and an elongate engagement member within said handle connected to said button.
- 4. A cleaning wand, as recited in claim 2, wherein said switch is mounted within said handle intermediate said trigger and said door.

- a cleaning head connected to said handle;
- a trigger mounted within a slot in said handle;
- a door connected to said handle, said door having a stop member; and
- a button having an elongate engagement member connected thereto in operative engagement therewith, said engagement member having a first end and a second end opposite said first end, said button received within a button slot within said handle, said button alternately slidable within said button slot to a first position on one end of said button slot, a second position in approximately the center of said button slot, and a third position on an opposite end of said button slot, said first end of said engagement member overlapping said trigger slot and said second end of said engagement member being disengaged from said stop member when said button is in said first position, to impede depression of said trigger and permit opening of said door, said first end of said engagement member overlapping said trigger slot and said second end of said engagement member engaging said stop member when said button is in said second position, to impede depression of said trigger and impede opening of said door, and said first end of said engagement member being substantially clear of said trigger slot and said second end of said engagement member being engaged with said stop member when said button is in said third position, to permit depression of said trigger and impede opening of said door.
