50 decibels — the Roborock Q5 Pro is basically a quiet conversation

Fifty decibels is about the sound of a quiet conversation or a refrigerator humming. That’s what the Roborock Q5 Pro measures on its quiet mode, and in practice it didn’t wake my son during his naps. That’s the highest praise a quiet-mode robot vacuum can earn.

Most vacuums in this category run louder because they’re pushing more air through tighter paths. The Q5 Pro manages to stay quiet without sacrificing cleaning quality — it’s not one of those “whisper mode” settings that barely picks up dust. The trade-off is that you’re running on lower suction, but for daily maintenance cleaning while the house is asleep, it’s perfect.
