Same as for graybeard, I use soapy water to help having the job of cleaning done pretty quickly and my oven to dry the beast for me.
Of course, dismantle/reassemble is still my job, and even with soapy water, the initial cleaning is mine (and takes about 15mn wih my 4 cylinders). Oiling the beast before storing it is also my job, and takes at least 20mn as I do not rely on WD40 or other kind of spray (but prefer paraffine oil).
All that to say, I don't see how we could drop the cleaning time - even with a sonic oven - under the hour, all included, for one weapon and its couple (4 for me) of cylinders.
I did not shoot with a semi-auto pistol for nearly 17 years now, but I do not remember such a rapid cleaning after a shooting session with my pistols. Sure dismantling/reassembling was quicker (as damn partial considering the 1858 cleaning for example) but excepted for theses quick phases, I see few differences in my (maybe wrong) memory (maybe double wrong as cleaning my weapons was somewhat a pleasure at that time - the only benefits I could give is the fact you can wait for days without cleaning them after firing with no impact on the weapon, what you cannot do with BP because of acidity).
