eufy Omni S2 vs iRobot Roomba 705X

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official Eufy and iRobot sites.
2026 verdict
The eufy Omni S2 takes this premium matchup against the iRobot Roomba 705X, with the better owner rating, a longer runtime at about 260 minutes per charge against 180, and twice the warranty at 2 years against 1. Its HydroJet 2.0 mop is the standout, generating electrolyzed water in real time with certification for germ removal, then hot-washing and hot-air drying at the dock, so the mop never sits damp. The iRobot Roomba 705X is a close and capable rival whose edge is automation reach: it adds IFTTT to the Apple HomeKit, Matter, Alexa and Google Home both robots share, and its AutoWash dock handles the PowerSpin mop cleaning on its own. Both navigate confidently, self-empty and mop hard floors without supervision. Choose the iRobot Roomba 705X if IFTTT routines are part of your setup, and the eufy Omni S2 for longer runs, a longer warranty and the more thorough mop cycle.
