It more than doubles the rated suction at 36,000 Pa, adds a self-washing and self-drying mop with automatic detergent and a 4 L tank, and supports Matter, Apple Home, SmartThings, Home Assistant and both Wi-Fi bands.

What the differences mean

Suction

The Roborock Saros 20 Sonic is rated at 36,000 Pa against 15,000 Pa on the Eufy Omni C28. Both scrub with a self-cleaning roller mop, but the Saros has far more headroom on carpet and heavy debris.

Smart home support

The Roborock Saros 20 Sonic supports Matter, Apple Home, SmartThings, Alexa, Google Home and Home Assistant over both Wi-Fi bands. The Eufy Omni C28 stops at Alexa, Google Home and Home Assistant, with no Matter, Apple Home or SmartThings.

Mopping

Both mops self-clean, but only the Roborock Saros 20 Sonic lifts the mop on carpet and doses detergent automatically from a 4 L tank, against 2.2 L on the Eufy Omni C28. Neither pad needs your hands during a run.

Runtime and noise

The Eufy Omni C28 runs up to 251 minutes and is rated at 54.89 dB, against 190 minutes and 64 dB on the Roborock Saros 20 Sonic. The cheaper robot goes longer and runs noticeably quieter.

Body and warranty

The Eufy Omni C28 stands 110.6 mm tall and the Roborock Saros 20 Sonic 79.8 mm, so the Saros reaches under lower furniture. Both carry a one year warranty, and the Saros dock is much heavier.

What owners say

The owners of the Eufy Omni C28 are the happiest talking about the mop: because the HydroJet roller rinses itself while it scrubs, several describe water coming back dirty from floors that looked clean, and they credit the 5-in-1 station with nearly removing the daily upkeep. The 15,000 Pa suction and DuoSpiral brush earn consistent praise for dog and cat hair without the roller clogging, and buyers call it quiet and good value. What they complain about is specific: drying the roller can take several hours, the robot can still run over cables and socks despite its LiDAR, a few units arrived with a defective water compartment, and replacement parts can be hard to find.

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.
