The iRobot Roomba 105 answers with a dramatically lower price and a compact charging base that needs none of the floor space the eufy Omni S2's large dock demands. This is largely a contest between two different classes of robot: one a premium vacuum-and-mop machine that empties, washes and dries itself, the other a dedicated, budget-priced vacuum with no mopping at all. Buyers who want mopping, stronger suction and the widest smart home reach should pick the eufy Omni S2; anyone who only wants dependable daily vacuuming without the dock's footprint should pick the iRobot Roomba 105.

What the differences mean

Mopping

The eufy Omni S2 cleans with a self-washing roller mop dosed with detergent by its station. The iRobot Roomba 105 has no mopping hardware at all.

Suction power

30,000 Pa on the eufy Omni S2 against 7,000 Pa on the iRobot Roomba 105, a large gap on carpet and stubborn debris.

Self-emptying

The eufy Omni S2's dock empties the bin, washes and dries the mop automatically. The iRobot Roomba 105 has no self-emptying dock, so the bin is emptied by hand.

Dock footprint

The eufy Omni S2's dock measures 476 x 387 x 670 mm and needs clearance on both sides. The iRobot Roomba 105 uses a small charging base with no comparable footprint, since it does not self-empty.

Price

The iRobot Roomba 105 is dramatically more affordable than the eufy Omni S2, reflecting how much less hardware and automation it carries.

What owners say

Owners of both robots like the mapping, but the similarities stop where mopping and price begin. eufy Omni S2 owners describe the roller mop lifting stuck-on mud and grime that pad mops leave behind, and say suction holds up even as the bin fills, though the very large dock needs clear space on both sides and a few units have shipped with repeated wheel or brush errors. iRobot Roomba 105 owners instead like that LiDAR mapping replaces random bumping with organized, row-by-row cleaning, and say the dustbin goes longer between emptyings than they expected for the price, but this model has no mopping at all and a bigger home can still need a mid-clean recharge.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
