What the differences mean

Suction

The eufy Omni S2 pulls 30,000Pa against 25,000Pa on the Dreame D30 Ultra, so it has more power for rugs and embedded dirt. Both handle pet hair well; the eufy simply sits higher on the scale.

Runtime and charging

The Dreame D30 Ultra is rated at 230 minutes of runtime against 179 for the eufy Omni S2, and both recharge in about 4 hours, so the Dreame finishes a large home with fewer trips back to the dock.

Smart home reach

The eufy Omni S2 supports Matter, which brings it into Apple Home and SmartThings, and it also has Bluetooth for setup. The Dreame D30 Ultra covers Alexa, Google Home and Home Assistant but has no Matter, Bluetooth, Apple Home or SmartThings.

Tanks and dock capacity

The Dreame D30 Ultra carries a 4.5L clean-water tank and a 3.2L dock bag, both larger than the eufy Omni S2 at 3L and 2.5L, so it goes longer between refills and bag changes. The eufy adds automatic detergent dosing, which the Dreame lacks.

Mopping hardware

Both wash, dry and lift their mops. The eufy Omni S2 uses a roller that scrubs sticky marks and doses detergent on its own, while the Dreame D30 Ultra uses pads that owners describe as maintenance-grade, keeping floors fresh rather than scrubbing dried spills.

What owners say

Owners of both robots praise the automation and the pet hair pickup, but they notice different strengths. Dreame D30 Ultra owners lead with quiet running and accurate mapping, and they single out brushes that do not catch long hair, the failure that frustrated them on earlier machines, with several buying a second unit. Their complaints are about running costs they felt were hidden and, at just over a year, mop pads that stopped being detected and a vacuum-only mode that misbehaved. eufy Omni S2 owners praise the roller mop for lifting mud and sticky marks that pad mops leave behind and a bin that keeps airflow up after a week of nightly runs, plus obstacle avoidance they rank among the best. Their gripes are a 98 mm body that will not fit under low furniture, a very large dock, an app and navigation that get confused on complex layouts, and a handful of units that threw repeated errors.
