50-55 dB is the sweet spot for toddler naps

Standard robot vacuums run at 65-75 dB, which is plenty loud enough to disrupt light sleep. For toddler naps, you want something under 55 dB on its standard cleaning mode — the quietest models hover around 50-55 dB, roughly the sound of a refrigerator hum or a quiet conversation. That’s the difference between a sleeping toddler and a screaming one.
