eufy Omni S2 vs iRobot Roomba 105 Combo

The eufy Omni S2 wins overall, with a longer battery life, more smart home integrations, Bluetooth connectivity and a dock that washes and dries its own mop pads and empties itself, all things the iRobot Roomba 105 Combo lacks. The Roomba's advantage is being the cheaper option.

Mop automation. Both robots technically support mopping, but the iRobot Roomba 105 Combo's mop uses plain water only, with no detergent, auto-washing or auto-drying. The eufy Omni S2 automates all of that at its dock, plus empties its own dustbin.

The eufy Omni S2 runs considerably longer per charge than the iRobot Roomba 105 Combo, which matters most for covering a larger home in a single cleaning run without a mid-clean recharge.

Yes, it is the more affordable of the two and the main reason to pick it over the eufy Omni S2, which positions itself as the pricier, more automated flagship.

Choose the iRobot Roomba 105 Combo if you want the most affordable vacuum-and-mop robot here and are fine with a water-only mop and manually emptying the dustbin.

Choose the eufy Omni S2 if you want a largely hands-off system: a self-emptying dock that also washes and dries its mop pads automatically, a longer runtime, and wider smart home connectivity, and you don't mind paying more for it.
