Roborock vs Roomba for quiet robot vacuuming: Roborock wins for noise-sensitive sleepers

Roborock (especially S7 and Q5 series) is noticeably quieter at around 55–60 dB, while Roomba hits 65–70 dB because it prioritizes suction. The difference is real but not dramatic — Roborock is the consensus pick for quiet operation, and running any vacuum on low suction mode makes it even quieter for overnight use.
