By default the CT 36 comes with a 3.5 m hose, which does wrap nicely in the hose garage. The 5.0 m hose is not likely to fully fit, but we’ll have to try it ourselves on Monday.
Probably because it is not a standard item likely to be out on a demo stand. So, they would have to fill in some paperwork to get one released from a warehouse somewhere (for Festool UK that would mean a German warehouse !) and then they cannot put it back in stock as it has been "used".
A 5 m smooth hose does fit in the garage of my CT26. I had to do it carefully but I imagine it would get easier with practice.
