The Saros 20 Sonic runs slightly longer per charge and connects over more radios, while the iRobot Roomba 705X answers back as the more affordable option and carries a higher owner rating, plus offers rare Apple HomeKit and Siri voice control alongside its self-washing PowerSpin roller mop. Both robots vacuum and mop with a self-emptying, self-washing dock, so day-to-day upkeep looks similar either way. Buyers who want the extra battery runtime and connectivity should pick the Roborock Saros 20 Sonic; anyone who wants Siri control and a friendlier price should consider the iRobot Roomba 705X.
