Review: Eufy Omni C28

Where the X10 Pro Omni had rotating mop pads, the rolling mop pad on the Omni C28 continuously self-cleans to prevent spreading dirt or grime to other parts of the house. Both apply downward pressure, but neither can spot dirtier places on their own as pricier, AI-powered robot vacuums will. Still, I was happy to see that it was able to scrub away some of the large dirt smudges in my entryway, though it didn’t get all of them. It also didn’t manage to scrub away all of the cherry juice I intentionally spilled in my routine mess setup for robot vacuum testing, even after sending the vacuum to do a second mopping job on one of the spots.

Still, the Omni C28 was able to raise its roller mop high enough when it switched from mopping my floors to vacuuming my living room rug that there was no hint of dampness anywhere. The older X10 did get my colleague Adrienne So’s carpet wet, but it didn’t get mine wet, though my carpet is a fairly low pile. It did a fine job vacuuming the carpet, though I could tell the difference in suction between this and more powerful vacuums I’ve tested.

The base station is nice and compact, and includes drying fans to dry off the roller mop. That does mean there’s a gentle fan noise in the background for a couple of hours after you use this robot vacuum, which was more annoying than I expected, but you could easily place this vacuum’s base station in a less central spot in your home so you don’t hear it. You could also set up a schedule for the vacuum to run in the morning and finish its drying job before you get home.

My favorite feature on the Omni C28 is that, even at this price point, it can still learn multiple maps. While it can’t climb up stairs, you can move it around your home and switch the maps in the app to the floor you’ve relocated to. This isn’t new for Eufy, as the older affordable model can do that too, but it’s nice to see the feature maintained when I’ve tried more expensive robot vacuums that don’t include it. It’s pretty simple to use; you’ll go to the maps, select “make a new map,” and then activate the robot to map. Once the map is made, you’ll switch to that map from the little map icon on the right side, which will label them with numbers in the order you created them.
