What's the best option for renters who can't drill?

Across the reviewers we read, the strongest renter-friendly options are floor-to-ceiling tension poles (no wall contact at all) and high-quality 3M-style adhesive caddies. Suction-cup-only designs are the most frequently returned, with reviewers on r/CleaningTips and r/DIYUK reporting they slide down or pop off as the rubber ages.
