All Festool cleaning kits work with the 27 mm hose. (Except those special few items meant for the 50 mm hose)
Only problem with the 27 mm is that the suction is not as good as with the 36 mm hose. And that's the hose its fault, not of the cleaning kit.
But I use the 27 mm hose all the time with the standard cleaning kit and I have no real problems.
