The eufy Omni S2 answers with stronger 30,000 Pa suction, a bigger water tank and two years of warranty against the Eufy E28's one. What actually sets them apart is what each one adds beyond vacuuming and mopping: the Eufy E28 packs a portable deep cleaner that lifts out of the dock for sofas, stairs and stains, while the eufy Omni S2 leans entirely into a self-rinsing roller mop and suction that does not fade as the bin fills. Both dock loudly when they empty and neither fits under very low furniture. Pick the Eufy E28 for the portable cleaner and the lower price, and the eufy Omni S2 for the strongest suction and mopping Eufy currently builds.

What the differences mean

Portable deep cleaner

The Eufy E28 includes a handheld cleaner that lifts out of the dock for sofas, stairs and stains, a job no floor robot can reach. The eufy Omni S2 has no equivalent, only the floor-cleaning robot and its dock.

Mop design

The eufy Omni S2 uses a roller mop that keeps rinsing itself while it scrubs. The Eufy E28's mop follows the standard design instead, washed and dried at the dock between runs rather than continuously.

Suction power

The eufy Omni S2 is rated at 30,000 Pa against the Eufy E28's 20,000 Pa, and eufy Omni S2 owners specifically credit that suction with staying strong because the bin does not clog as it fills.

Clearance under furniture

At 98 mm the eufy Omni S2 is shorter than the Eufy E28's 111 mm, though owners of both report some low furniture and kitchen toe-kicks neither one reaches.

Warranty

The eufy Omni S2 carries a 2 year warranty against 1 year on the Eufy E28.

What owners say

Owners of both praise how completely each one automates the chores: fast first-run mapping, a dock that empties, washes and dries the mop with no manual step, and support for practically every smart home platform. Eufy E28 owners often name the portable deep cleaner as the reason they picked this model over a plain robot, using it on sofas, stairs and stains the floor unit cannot reach, while their main complaint is how heavy and tall the combined unit is to carry between floors. eufy Omni S2 owners talk most about suction that stays strong because the bin does not clog and a roller mop that lifts mud and sticky marks other robots leave behind, while several report the app getting confused on complex layouts and a few units throwing repeated errors.
