The eufy Omni S2 is the stronger cleaner. It delivers 30000Pa against 7000Pa, pairs that with a roller mop that lifts stuck-on dirt and a two-year warranty against one, and its dock doses detergent automatically while the iRobot Roomba 505X spins pads and tops up water from its AutoWash dock. Both robots empty, wash and dry their own mops and both reach the major smart home platforms. The eufy also runs quieter at 59 dB and measures 98 mm against 107 mm. Choose the iRobot Roomba 505X when the lower price and a 5 GHz network lead, and the eufy Omni S2 for stronger suction, a better mop and a longer warranty.

What the differences mean

Suction power

30000Pa on the eufy Omni S2 against 7000Pa on the iRobot Roomba 505X. That is the widest gap in this pairing and the reason the eufy is the stronger dry cleaner by a clear margin.

Mop design

The eufy Omni S2 uses a roller mop that owners say lifts mud and sticky marks, and its dock doses detergent automatically. The iRobot Roomba 505X spins two pads that the AutoWash dock washes and heat-dries, with water drawn from the dock and no auto-detergent dispenser.

Warranty

eufy covers the Omni S2 for two years, while the iRobot Roomba 505X carries a one-year warranty. On two robots with pumps and docks, the longer cover is worth weighing.

Dock footprint

The eufy Omni S2 dock measures 476 x 387 x 670 mm and one owner found it needs clear space on both sides to dock reliably. The iRobot Roomba 505X dock is smaller at about 450 x 343 x 470 mm, which is easier to place.

Height and clearance

The eufy Omni S2 is 98 mm tall and the iRobot Roomba 505X is 107 mm. The eufy is the lower of the two, though neither is slim enough for very low furniture.

Wi-Fi and radios

The iRobot Roomba 505X joins 2.4 GHz and 5 GHz and lists Bluetooth. The eufy Omni S2 is 2.4 GHz only, also with Bluetooth. A router that only broadcasts 5 GHz is the practical reason to take the Roomba.

What owners say

eufy Omni S2 owners say the roller mop is the difference, lifting ingrained mud and sticky patches better than the robot mops they had before, and they rate the suction for holding airflow after a week of nightly runs instead of caking the filter. Obstacle avoidance that marks shoes, cords and dishes on the map earns nearly as much praise. Their warnings are a tall 98 mm body that misses some low furniture, a very large dock, software that can get lost on complex layouts, and a few units with repeated errors. iRobot Roomba 505X owners highlight the AutoWash dock and reliable pet-hair pickup, and mention a loud cleaning cycle and fiddly first pairing.

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.
