What the differences mean
Mopping
Eufy Omni C28 mops with a HydroJet roller that rinses itself while it scrubs. iRobot Roomba 205 has no mopping function at all, so hard floors still need a separate pass.
How each one handles debris
Eufy Omni C28 empties into a full Omni Station that also washes and dries its mop. iRobot Roomba 205 skips the auto-empty dock entirely and instead compresses debris inside the robot with its internal DustCompactor, trading self-washing for a much smaller charging footprint.
Suction power
Eufy Omni C28 is rated at 15,000 Pa, more than double the iRobot Roomba 205's 7,000 Pa.
Battery life
Eufy Omni C28 runs up to 251 minutes on a charge, well beyond the iRobot Roomba 205's 120 minutes, so it covers more floor before docking.
Wi-Fi band
iRobot Roomba 205 connects on both 2.4 GHz and 5 GHz Wi-Fi. Eufy Omni C28 is 2.4 GHz only.
Which one to buy if
- you want vacuuming and mopping handled by one machine with minimal emptying
Eufy Omni C28's Omni Station washes and dries the mop and empties the bin on its own, which the vacuum-only iRobot Roomba 205 cannot do.
- you specifically want to avoid a bulky auto-empty dock
iRobot Roomba 205's internal DustCompactor needs only a small charging base instead of a full station.
- your router only reaches some rooms on 5 GHz
iRobot Roomba 205 supports dual-band Wi-Fi; the Eufy Omni C28 is 2.4 GHz only.
- you have a large single-floor home to cover in one run
251 minutes of runtime on the Eufy Omni C28 covers far more ground than the iRobot Roomba 205's 120.

What owners say
Eufy Omni C28 owners describe the HydroJet roller mop as the reason to buy it, since it rinses itself continuously and comes back with visibly dirty water even on floors that already looked clean, and they praise the 15,000 Pa suction for pulling pet hair, dust and debris along edges. Their main complaint is that the mop takes several hours to dry after a cycle, and a few report the robot still snagging on cables despite its LiDAR obstacle avoidance. iRobot Roomba 205 owners like how rarely the DustCompactor needs emptying and how much smaller its charging base is than a bagged auto-empty dock, with several specifically choosing it because they wanted fewer moving parts to break, but the most common complaint is battery life, with more than one recharge cycle often needed to finish a single floor.
Frequently Asked Questions
Which is better overall: Eufy Omni C28 or iRobot Roomba 205?
The Eufy Omni C28 wins overall, mainly because it mops as well as vacuums and empties and washes itself at a full Omni Station. The iRobot Roomba 205 is the better pick for buyers who only want a vacuum-only robot at a lower price with no dock at all.
What is the biggest difference between the Eufy Omni C28 and the iRobot Roomba 205?
Mopping and dock design. The Omni C28 vacuums and mops with a self-washing roller at a self-emptying station, while the Roomba 205 only vacuums and uses an internal DustCompactor to shrink debris inside the robot instead of using any dock at all.
Does the iRobot Roomba 205 mop floors?
No. It is a vacuum-only robot with no mopping, detergent compatibility or auto mop features at all. If mopping matters, the Eufy Omni C28 is the one to choose.
Which one needs less hands-on maintenance?
The Eufy Omni C28's Omni Station handles emptying, mop washing and drying automatically, so it needs the least routine attention. The Roomba 205's DustCompactor still cuts down on emptying, but it has no dock at all to handle mopping or washing.
Who should buy the Eufy Omni C28?
Buyers who want a full vacuum-and-mop combo that empties and cleans itself with minimal manual involvement, especially in homes mixing hard floors and carpet.
Who should buy the iRobot Roomba 205?
Buyers on a tighter budget who only need vacuuming, do not want a bulky dock of any kind, and are fine handling floor mopping themselves.
