What the differences mean
Suction
The Roborock Saros 20 is rated at 36,000 Pa and the Eufy Omni C28 at 15,000 Pa, so the Roborock lifts more debris from carpet and rugs per pass. On bare hard floor the two are closer than those figures suggest.
Wi-Fi bands
The Roborock Saros 20 connects over both 2.4 GHz and 5 GHz, while the Eufy Omni C28 is 2.4 GHz only. On a crowded network the 5 GHz band gives the Roborock a steadier link, though both still need a 2.4 GHz network for setup.
Water and dock capacity
The Roborock Saros 20 carries a 4 L clean-water tank against 2.2 L on the Eufy Omni C28, so it refills less often on a long hard-floor run. The eufy takes the dock-bin comparison with a 3 L bag against 2.5 L.
Runtime
The Eufy Omni C28 is rated for 251 minutes per charge and the Roborock Saros 20 for 200. On a large single floor the eufy finishes in one pass more often, while the Roborock returns to recharge sooner.
Smart home platforms
The Roborock Saros 20 supports Apple Home, SmartThings, Home Assistant and Matter alongside Alexa and Google Home. The Eufy Omni C28 covers Alexa, Google Home and Home Assistant but supports none of the others.
Which one to buy if
- you have carpet and a heavy shedder
The Roborock Saros 20 is rated at 36,000 Pa, more than twice the eufy, which is what pulls embedded hair out of carpet pile.
- you want the longest run on one charge
The Eufy Omni C28 is rated at 251 minutes against 200 for the Roborock Saros 20, so it covers a bigger floor before recharging.
- your smart home runs on Apple Home or Matter
The Roborock Saros 20 joins Apple Home, SmartThings and Home Assistant over Matter, which the Eufy Omni C28 cannot do.
- budget and owner rating come first
The Eufy Omni C28 is the cheaper and better reviewed of the pair and still empties, washes and dries its own mop.

What owners say
Owners of both robots start from the same place: mapping and setup are quick, and the dock takes emptying and mop cleaning out of their week. Roborock Saros 20 owners single out how little upkeep it asks for and how well the 36,000 Pa suction pulls pet hair out of carpet, and many run it overnight because it stays quiet. Their warnings are about a mop-cleaning solution that is not in the box, threshold climbing that is inconsistent and battery that drains fast on deep-clean carpet runs. Eufy Omni C28 owners praise the HydroJet roller mop that scrubs rather than smears and a station that empties, washes and hot-air dries on its own, with the lower price a repeated theme. Their gripes are slow mop drying, catching on cables and clutter, and some units arriving with a defective water compartment.
