Why is the TS 75 making so much saw dust and the CT 26 not catching? Is it because of the size hose that comes with the CT26?
[welcome] to The FOG, Rocky
The CT26 includes a 27mm AS hose, which will fit onto all common Festools. Some will only accept the 27mm hose, such as OF1010 and MFK700 routers, jig saws, Domino 500 and the sanders.
The 36mm AS hose is an option. It fits over the outside of the Kapex, TS55 and TS75 dust extraction port, and fits the same way on the hand planers, OF1400 and OF2200 routers.
I always recommend using the 36mm AS hose with both Festool track saws. You will get better dust extraction, but more to the point, the somewhat less flexible 36mm hose is far less likely to hang up on guide rails. With sanders you need flexible movement in all directions. However, a track saw is only moving forward in a straight line. This is the whole point of a guide rail.
Another reason for the 36mm hose is improved performance with the cleaning tools. You can simply buy a 36mm AS hose, but the deal so many of us make is to buy the version of the Tradesman Cleaning set that includes many cleaning tools plus a 36mm AS hose. Now after the job is done or the shift ends you can quickly clean up any mess not extracted from the tools. On the job not every tool is made by Festool. Even hand tools can create mess.
