5 Reasons the Narwal Flow 2 Is Quieter Than the Roborock Qrevo S
- The Narwal Flow 2 runs at 67 decibels, while the [Roborock Q](https://www.amazon.com/s?k=Roborock+Q&tag=wehavethat-20)revo S runs at 75 dB. That 8-decibel difference is significant in real-world use.
- An 8-decibel drop is not just a small change — it cuts perceived loudness by about half. The Flow 2 sounds much less intrusive.
- The Flow 2 is a better fit if you work from home. It won’t compete with phone calls or video meetings the way the louder Qrevo S will.
- Lower noise means you can run the vacuum at night or while watching TV without disruption. The Qrevo S is more likely to be annoying in quiet settings.
- If noise sensitivity matters to you, the Flow 2 is the clear choice. The Qrevo S is louder and less suitable for noise-conscious households.
