What the differences mean
Mopping
The Eufy Omni C28 has a roller mop that rinses itself while it scrubs and is washed and hot-air dried at the station. The Dreame D20 Air Plus uses a flat pad fed by a 280 ml tank on the robot, with no washing, drying or lifting, and it shows on dried, greasy spills.
Water handling
The Eufy Omni C28 refills from a 2.2 L clean-water tank in its station and collects wastewater there. The Dreame D20 Air Plus carries a 0.28 L tank on the robot that has to be refilled by hand, so it wants more attention during a big mopping run.
Runtime
The Eufy Omni C28 is rated at 251 minutes and the Dreame D20 Air Plus at 150, and the eufy recharges in about 3.5 hours against 4.5 for the Dreame. On a large home the eufy covers more floor in a single pass.
Warranty
The Dreame D20 Air Plus carries a 3-year warranty and the Eufy Omni C28 a 1-year one. For a buyer who weighs the cost of a repair a few years out, that is the clearest reason to choose the Dreame.
Suction and dock bin
The Dreame D20 Air Plus is rated at 20,000 Pa against 15,000 Pa on the Eufy Omni C28, and its 4 L dock bag edges the eufy's 3 L. Both are rated well above what a hard-floor home actually needs.
Which one to buy if
- you want the mopping handled automatically
The Eufy Omni C28 washes and hot-air dries a self-rinsing roller mop at its station, where the Dreame D20 Air Plus uses a hand-refilled flat pad.
- a low price and a long warranty matter most
The Dreame D20 Air Plus is the cheaper of the pair and carries a 3-year warranty against 1 year for the Eufy Omni C28.
- you mostly vacuum hard floors and mop by hand anyway
The Dreame D20 Air Plus gives 20,000 Pa, anti-tangle brushes and a 4 L auto-empty dock without paying for mopping hardware you will not use.
- you want the longest run between charges
The Eufy Omni C28 is rated at 251 minutes against 150 for the Dreame D20 Air Plus, so it needs fewer returns to the dock.

What owners say
Owners of both robots agree on the vacuuming: strong pickup on hard floors, an anti-tangle brush that copes with long hair, and automatic carpet boost. Dreame D20 Air Plus owners call the LiDAR mapping fast and accurate and the 4 L auto-empty dock the feature that lets them forget the robot for days, and they rate it well above its price. Their warnings are the flat-pad mopping, a water tank that lives on the robot and needs manual refills, and a tall LiDAR turret that blocks some under-furniture access. Eufy Omni C28 owners single out the HydroJet roller mop that scrubs instead of smearing and a 5-in-1 station that empties, washes and hot-air dries on its own, at a price they call good value. Their gripes are slow mop drying, catching on clutter and a few units arriving with a defective water compartment.

Frequently Asked Questions
Which is better overall: Dreame D20 Air Plus or Eufy Omni C28?
The Eufy Omni C28, if you want mopping and vacuuming handled automatically: it washes and dries a roller mop and runs far longer. The Dreame D20 Air Plus is the smarter buy for a hard-floor home that mostly vacuums, since it costs less, has a longer warranty and still auto-empties.
What is the biggest difference between the Dreame D20 Air Plus and the Eufy Omni C28?
The mopping. The Eufy Omni C28 scrubs with a roller that rinses itself and is washed and dried at the station, while the Dreame D20 Air Plus drags a flat pad fed by a tank on the robot, with no washing, drying or mop lifting.
How good is the mopping on the Dreame D20 Air Plus?
It is a light refresh rather than a deep mop. The flat pad is fed by a 280 ml tank on the robot and is rinsed by hand, and there is no mop washing or drying at the dock. The Eufy Omni C28 is the one of the two built around real mopping.
Which robot has the longer warranty?
The Dreame D20 Air Plus, with 3 years against 1 year for the Eufy Omni C28. It is also the cheaper of the two, which is why it suits a buyer focused on value and low maintenance over mopping.
Who should buy the Dreame D20 Air Plus?
A pet home with mostly hard floors that wants strong suction, an anti-tangle brush and a 4 L auto-empty dock, is happy to mop by hand, and values the lower price and the 3-year warranty.
Who should buy the Eufy Omni C28?
A mixed-floor home that wants its mop washed, hot-air dried and refilled automatically, needs a long 251-minute runtime, and would rather pay more for a robot that washes the floor properly instead of wiping it.
