The fact that our apartment has zero closets may come off as modern and vaguely Scandinavian in the bedroom, say, but it's not as easy to make the contents of a utility closet look cool.
Our broom, mop and related paraphernalia would lean — and subsequently fall to the floor in an aggravating tangle — on a new wall every week until we found the Store 'n Slide. The footprint of its mounting hardware is limited to the length of the rack itself, rather than the length of the track, meaning it can slide past the edge of the wall, as we've done below.
We've found that it breaks the usual rule that if you can't see it, you won't use it. Since retrieval and storage of our cleaning tools are so much easier, we're actually motivated to sweep and mop more. Oh joy.
