What the differences mean
Suction
The Dreame L40 Ultra Gen 2 is rated at 25,000 Pa and the Eufy Omni C28 at 15,000 Pa, so the Dreame has a clear edge on carpet and embedded debris. The eufy's roller mop stays the more forgiving of the two on hard floor.
Water and dock capacity
The Dreame L40 Ultra Gen 2 carries a 4.5 L clean-water tank and a 3.2 L dock bag, against 2.2 L and 3 L on the Eufy Omni C28. On a large floor the Dreame refills less often and empties slightly less often too.
Warranty
The Dreame L40 Ultra Gen 2 carries a 3-year warranty and the Eufy Omni C28 a 1-year one. For anyone pricing out a longer ownership, that is a real gap in the Dreame's favour.
Multi-floor mapping
The Dreame L40 Ultra Gen 2 stores multi-level maps for up to four floors, while the Eufy Omni C28 documents multi-room mapping. In a townhouse or a home with a basement, the Dreame is the one built to follow you between floors.
Runtime
The Eufy Omni C28 is rated at 251 minutes and the Dreame L40 Ultra Gen 2 at 231, so the eufy finishes a larger floor on one charge. The Dreame recharges in about 3.5 hours.
Which one to buy if
- your home has more than one floor
The Dreame L40 Ultra Gen 2 stores multi-level maps for up to four floors, where the Eufy Omni C28 documents multi-room mapping on one.
- you have carpet or a heavy shedder
The Dreame L40 Ultra Gen 2 is rated at 25,000 Pa against 15,000 Pa, so it lifts more embedded hair and grit from carpet.
- a long warranty matters to you
The Dreame L40 Ultra Gen 2 carries a 3-year warranty against 1 year for the Eufy Omni C28.
- you want the longest runtime and the lower price
The Eufy Omni C28 is rated at 251 minutes against 231 and costs less, while still washing and drying its roller mop automatically.

What owners say
Owners of both robots focus on how little the dock leaves for them. Dreame L40 Ultra Gen 2 owners praise the self-emptying, self-washing and hot-air drying dock, the 25,000 Pa suction on dust and pet hair, and mapping that is fast and accurate across multiple floors. Their recurring complaints are hair tangling in the wheels or brush, an app with a real learning curve, and an auto-detergent dispenser sold separately. Eufy Omni C28 owners highlight the HydroJet roller mop that scrubs with clean water and a 5-in-1 station that empties, washes and dries, and call it quiet and good value. Their gripes are slow mop drying, catching on clutter and some units arriving with a defective water compartment.
Frequently Asked Questions
Which is better overall: Dreame L40 Ultra Gen 2 or Eufy Omni C28?
The Dreame L40 Ultra Gen 2 for a multi-floor home or one with carpet: it has more suction, a larger water tank, multi-level maps and a 3-year warranty. The Eufy Omni C28 is the better value, cheaper with a longer runtime and the same self-cleaning dock routine.
What is the biggest difference between the Dreame L40 Ultra Gen 2 and the Eufy Omni C28?
Suction and capacity. The Dreame L40 Ultra Gen 2 is rated at 25,000 Pa with a 4.5 L water tank, against 15,000 Pa and 2.2 L on the Eufy Omni C28. The Dreame also carries a 3-year warranty, while the eufy runs a little longer and costs less.
Can the Dreame L40 Ultra Gen 2 map more than one floor?

Do both robots wash and dry their own mop?

Who should buy the Dreame L40 Ultra Gen 2?
A multi-floor or carpet-heavy home that wants the strongest suction of the pair, a 4.5 L tank, up to four saved floor maps and a 3-year warranty, and does not mind the app's learning curve.

A single-floor, hard-floor home on a budget that wants real roller mopping, automatic mop washing and drying, the longest runtime of the pair and a lower price.
