Call it TikTok brain, but if a cleaning gadget keeps popping up on my feed, I’m taking it as a sign.

To be honest, I’m sold. The one currently living rent-free in my head is a compact, multi-surface handheld steamer that’s going for under $50 right now (yes, before the frenzy of Amazon’s Big Spring Sale kicks off).
