Published noise figures

ECOVACS also gives vacuum-only figures in standard mode: 61.8 dBA for the X11 OmniCyclone and 64.5 dBA for the X9 PRO OMNI. Makers measure noise in different ways and in different modes, so a quiet-mode figure and a standard-mode figure can’t be compared directly. Five robots here have no published cleaning-noise figure: Roborock Saros 20, eufy Omni S2, Dreame D30 Ultra, Roborock QV 35A, SwitchBot S20.

Quieter in practice

• Set runs for when nobody is home, if your robot’s app has a schedule.
• Use quiet mode for everyday runs and a stronger mode now and then.
• The figures above are for cleaning. A self-emptying dock also makes noise while it empties the robot, and we don’t count figures for that. See dust bag days.
