13. The device of claim 12 , wherein the second display is lateral to the trigger such that the trigger avoids extending over the second display.

14. The device of claim 12 , wherein the first display and the second display having an identical modality of displaying.

15. The device of claim 11 , wherein the trigger is configured to cause the first fluid and the second fluid to be output from the drain gun controllably in a plurality of stages.

16. The device of claim 8 , wherein the trigger is completely external to the handle.

17. The device of claim 8 , wherein the cartridge is external to the channel when the cartridge is stored in the handle and engaging the inlet.

18. The device of claim 8 , wherein the cartridge has the first central longitudinal axis when the cartridge is stored in the handle and engaging the inlet and the channel has the second central longitudinal axis perpendicular to the first central longitudinal axis.

19. The device of claim 8 , wherein the inlet rectilinearly spans between the channel and the cartridge when the cartridge is stored in the handle and engaging the inlet.

20. The device of claim 8 , wherein at least two of (a) the trigger is completely external to the handle, (b) the cartridge is external to the channel when the cartridge is stored in the handle and engaging the inlet, (c) the cartridge has the first central longitudinal axis when the cartridge is stored in the handle and engaging the inlet and the channel has the second central longitudinal axis perpendicular to the first central longitudinal axis, or (d) the inlet rectilinearly spans between the channel and the cartridge when the cartridge is stored in the handle and engaging the inlet.

21. The device of claim 8 , wherein at least three of (a) the trigger is completely external to the handle, (b) the cartridge is external to the channel when the cartridge is stored in the handle and engaging the inlet, (c) the cartridge has the first central longitudinal axis when the cartridge is stored in the handle and engaging the inlet and the channel has the second central longitudinal axis perpendicular to the first central longitudinal axis, or (d) the inlet rectilinearly spans between the channel and the cartridge when the cartridge is stored in the handle and engaging the inlet.

22. The device of claim 8 , wherein (a) the trigger is completely external to the handle, (b) the cartridge is external to the channel when the cartridge is stored in the handle and engaging the inlet, (c) the cartridge has the first central longitudinal axis when the cartridge is stored in the handle and engaging the inlet and the channel has the second central longitudinal axis perpendicular to the first central longitudinal axis, and (d) the inlet rectilinearly spans between the channel and the cartridge when the cartridge is stored in the handle and engaging the inlet.
