Yeah, this can be a hassle. I got the hose garage right away when it came out, well worth the money in my book. I remember taking a nasty tumble down a set of brand new spiral stairs because the hose of the shopvac I was carrying came free and right under my foot. We had just finished building this set of wooden spiral stairs, they were beautiful. I wasn't hurt, just a few bruises, but the stairs took some damage as the vac bounded its way down. The guy I was working for at the time was a great carpenter so he was able to fix the damage so the story had a happy ending.

You don't have to pull off the hose and worry about the dust when carrying it separately. The cord will also fit in the garage so you don't have to struggle to make it fit on the cord wrap on the back of the vac. And there is the added safety of keeping everything secure so you greatly reduce or eliminate your chances of tripping over a loose cord or hose while carrying the vac. This is one accessory that helps the Festool vacs be faster, easier and smarter (sorry, I couldn't resist
