eufy Omni S2 vs iRobot Roomba 105X

The eufy Omni S2 is the stronger pick overall, leading on rating, warranty, battery life, connectivity, integrations, mopping and self-emptying. The iRobot Roomba 105X only wins on price, and every other measured category, including navigation type, obstacle detection, cliff detection, multi-room mapping, no-go zones and carpet cleaning, ties between the two.

The eufy Omni S2 is a vacuum-and-mop system with a self-emptying dock that also washes and dries its own mop pad automatically, while the iRobot Roomba 105X is vacuum-only with no mopping hardware at all and no self-emptying dock, so its bin has to be emptied by hand.

The eufy Omni S2 comes with a 2 year warranty, double the 1 year warranty on the iRobot Roomba 105X. Warranty length is one of the few areas where the 105X usually ties with competitors, so this gap is more unusual than most of its other comparisons.

The eufy Omni S2 runs for about 260 minutes per charge, noticeably longer than the iRobot Roomba 105X's roughly 200 minutes, and both machines support auto-recharge to return to their dock when the battery runs low.

Buyers who want automated mopping alongside vacuuming, a dock that empties itself and cleans its own mop, longer battery life, broader smart home integrations and a longer warranty should choose the eufy Omni S2, especially if upfront cost is a secondary concern.

Shoppers who only need dependable, LiDAR-mapped vacuuming and want to spend as little as possible should pick the iRobot Roomba 105X, since price is its one clear advantage over the eufy Omni S2 and it still covers multi-room mapping, no-go zones and carpet cleaning.
