The Eufy Omni C28 is the stronger cleaner. It pulls 15000Pa against 7000Pa, runs up to 251 minutes against 180, recharges in 3.5 hours instead of 4.5 and adds an automatic detergent dispenser to a station that empties, washes and dries the mop, and owners rate it the higher of the two. Both navigate with LiDAR, map several rooms, lift their mops over carpet and self-empty. Pick the iRobot Roomba 505X for an Apple Home or Matter household or a 5 GHz network, and the Eufy Omni C28 for the deepest clean and the most hands-off station.

What the differences mean

Suction

The Eufy Omni C28 is rated at 15000Pa, more than twice the 7000Pa of the iRobot Roomba 505X. On rugs and in the grooves of hardwood that is the difference between lifting embedded hair and skimming the surface.

Runtime and charging

The Eufy Omni C28 runs up to 251 minutes and recharges in 3.5 hours; the iRobot Roomba 505X runs 180 minutes and takes 4.5 hours. In a large home the Eufy finishes more floor on one charge.

Smart home platforms

Both work with Alexa, Google Home and Home Assistant. Only the iRobot Roomba 505X adds Apple Home, SmartThings and Matter, so it is the one that shows up in the Home app.

Station

Both docks self-empty and wash and dry the mop. The Eufy Omni C28 also doses detergent on its own from a 2.2L tank, where the iRobot Roomba 505X takes detergent but has no automatic dispenser, though its water tank is bigger at 3L.

Wi-Fi

The iRobot Roomba 505X connects on 2.4 or 5 GHz; the Eufy Omni C28 on 2.4 GHz only. Both list Bluetooth.

What owners say

Owners of both robots lead with the same thing: a dock that empties the bin and washes and dries the mop pads, so the robot runs for weeks with little attention, and both groups say it handles pet hair and daily dust. Eufy Omni C28 owners single out a roller mop that rinses itself as it scrubs, with dirty recovered water as proof, and a robot quiet enough to live with, while they complain about mop drying that takes hours, getting caught on cables and socks and a few units with a faulty water compartment. iRobot Roomba 505X owners talk about accurate LiDAR maps and single-pass vacuuming and mopping, and their complaints are a loud cleaning cycle on deep clean and fiddly Wi-Fi pairing or mapping resets.
