Hi Bill,
Ya the detachable power cord is sweet...
But on my Festool power tools; AFT 55, AFT 65, DX 93, RS 2 & RAS 115 they have to plug in directly to the CT 22 to trigger the vacuum. When I use on of these tools with the Boom, I swing the detachable cord back out of the way & hook it to the Boom arm on one of the "extra" hooks on the black plastic brackets toward the back of the vacuum that hold the hose/detachable power cord. Thus it loops back on itself, I do this also when moving the vacuum with Boom on also. I also don't use the very bottom black bracket for the vacuum hose to get a little more length out of the hose, thus this "spare" hose bracket allows me to loop the hose also out of the way when not in use or when moving with the Boom arm on.
On the non-detachable cord tools I will plug it into the vacuum then used the "extra" hook on the very tip or last black plastic bracket that holds the hose/detachable cord to run the cord from over head & avoid the cord coiled at my feet. However cord is "just" a little shorter than the vacuum hose & does not work quit as well as when I use it with a detachable cord tool.
