eufy Omni S2 vs iRobot Roomba Combo 10 Max robot + AutoWash dock

The iRobot Roomba Combo 10 Max robot + AutoWash dock wins the overall comparison, ahead on price, connectivity, smart-home integrations, cliff detection and no-go zones. The eufy Omni S2 still has an edge in runtime and owner rating, so the right pick depends on whether ecosystem breadth or those two areas matter more to you.

Smart-home reach. The iRobot Roomba Combo 10 Max robot + AutoWash dock adds Bluetooth plus Samsung SmartThings, Home Assistant, IFTTT and Matter support, along with cliff detection and no-go zones, none of which the eufy Omni S2 lists. The eufy Omni S2 instead focuses on hygiene, with electrolyzed-water mopping and a hot-wash, hot-dry dock cycle.

The iRobot Roomba Combo 10 Max robot + AutoWash dock does, supporting Amazon Alexa, Apple HomeKit, Google Home, Samsung SmartThings, Home Assistant, IFTTT and Matter. The eufy Omni S2 is limited to Amazon Alexa and Google Home.

The eufy Omni S2 has the longer runtime of the two, an advantage it holds onto even though the iRobot Roomba Combo 10 Max robot + AutoWash dock wins the overall comparison on other fronts.

Buyers who want the longer runtime, an electrolyzed-water mopping system with a hot-wash and hot-dry dock cycle, and who are comfortable with a narrower Alexa and Google Home integration list rather than a wider smart-home ecosystem.

Buyers who want the broadest smart-home ecosystem support in this pair, including Apple HomeKit, Samsung SmartThings, Home Assistant, IFTTT and Matter, plus built-in cliff detection and no-go zones, and who are willing to weigh the reliability complaints noted in its own owner reviews against those advantages.
