Have you considered that your mentioned "doing cleaning for 5 hours" may be part of your issue.I print almost everyday. I am trying to print now and have been doing cleanings for the last 5 hours non-stop. Still clogged. This is a frequent situation.
Thorough Cleaning UNDER the printing unit (The print head and nozzles) is necessary to actually do a thorough job of cleaning "Caked and gummed up" and removed from that area so the print Nozzles can allow ink to be passed through the print nozzles freely.
You are probably just getting the already caked and partially dried ink to be slightly softer (more gummy) but NOT actually removing the "sticky MESS" from that area.
Another comment regarding newer vs older Epson Printers regarding clogging.
I have never initiated a Head Cleaning for my 8 year old Epson 2200. Likewise, I also have the same experience with my 10 month old Epson 3880.
Proper care, Maintenance, and usage is needed for ANY printer, any Model, and any Brand.
