I have one. Mine come with a storage bag for the tools, which fits well in a place in the closet where I store the vac, so that's what I do. I think there is a round place to store it on the left side (as you're facing it), but because the crevice tool is so long, it doesn't fit in quite right. I fooled with it in the store before I bought it and the salesperson said she didn't think that tool was meant to be stored onboard, which I went along with it because I had a better alternative. HTH.
