eufy Omni S2 vs iRobot Roomba Max 705

The eufy Omni S2 wins the overall comparison, ahead on suction power, runtime, owner rating and mopping. The iRobot Roomba Max 705 does not mop at all, but it counters with a lower price, cliff detection, no-go zones and broader smart-home integrations.

Mopping. The eufy Omni S2 vacuums and mops in one pass with an electrolyzed-water mopping system, while the iRobot Roomba Max 705 is a vacuum-only robot with no water tank or mop pad at all.

No. The iRobot Roomba Max 705 is a dedicated vacuum with no mopping functionality whatsoever, so it skips the water tank, detergent dispensing, and mop washing and drying features that the eufy Omni S2 includes.

The eufy Omni S2 has the stronger suction of the two, along with a longer runtime per charge, making it the pick for buyers prioritizing raw cleaning power and coverage.

Buyers who want a single robot that both vacuums and mops, with stronger suction and a longer runtime, and who are fine with a narrower Alexa and Google Home integration list rather than the widest smart-home ecosystem support.

Buyers who only need vacuuming (no mopping), want built-in cliff detection and no-go zones for stairs and off-limit areas, prioritize the broadest smart-home integrations including Apple HomeKit and Matter, and prefer a lower price.
