This will vary depending on what you are cleaning what you are shooting and what you have done in the way of mods.
Since I go to shoot and clean because it is necessary [some people say they enjoy cleaning] I have guns that do not blow back so I have nothing in the action to clean with my traditional and soap and water it takes a half hour with Blackhorn and the Triumph or the Endeavor Encore it takes 5 to 10 minutes depending on where I do it at the range with every thing all laid out it does not take long. Also I mix my own cleaner or use Montana X Blackhorn cleaner, this does make a difference.
With the breach plug the way I mod them I can shoot all day and have only a small amount of carbon to clean out. If you are interested the way I mod them is by running a #21 drill through then drilling in just far enough to set the Lehigh vent liner so the vent is in the same place that TC originally designed it, they have far and away the best design according to my tests.
