Yes the Felix has two spaces on a slide-able permanent height adjustable holder. It fixes to the spine via one crosshead screw but ingeniously is able to slide up and down dependent on the user's choices. Whilst it can accomodate the standard long crevice tool and T shaped flat upholstery tool, I don't often use the crevice tool and much prefer to use the T shaped tool with the larger stair mini turbo brush locked at the top. That's where it adds the weight all of a sudden!
The Miele should have a similar clip - mine does, or rather I had to re-order one which allows you to store two cleaning tools on board - crevice tool & flat T shaped upholstery tool. I have since used my Miele a couple of times, but I much prefer the heavier action of the more modern Felix - the built in hose, though short is perfect for me to clean around the kitchen worktops and SEBO also sell an additional permanently fixed clip for the Felix spine where effectively three tools can be added, but then limits the height movement of the original 2 part tool storer.
