Main trade-off
eufy Omni E25
The roller system does not provide Dreame's extending rotary mop pad.
Head-to-head
Choose Omni E25 if you want a roller washed during use and automatic detergent dispensing in the reviewed base setup. Choose L40 Ultra Gen 2 if you prefer two rotating mop pads with physical extension and a separately extending side brush. Dreame's solution module and TriCut brush are optional, so compare the actual package before treating them as included.
Before you choose
E25 refreshes its roller during use. Dreame cleans its rotating pads when they return to the station. That is a useful process choice for someone comparing roller and pad upkeep, but it cannot prove which leaves a particular floor cleaner without a matched test.
What this is based on
The E25 HydroJet description places washing in the mopping process. Dreame's DuoScrub and AceClean descriptions put rotary pads on the floor and pad washing at the dock.
Main trade-off
The roller system does not provide Dreame's extending rotary mop pad.
Main trade-off
Automatic solution dosing needs a separately purchased module.

Winner by situation
E25 provides HydroJet roller washing. Dreame uses rotary pads.
Dreame uses the requested pad system. E25 uses a roller.
Dreame's reviewed base offer requires its separately purchased module.
Dreame extends a rotary pad. E25's CornerRover side arm is a different mechanism.
E25 uses DuoSpiral. Dreame's base specification has a rubber brush and treats TriCut as optional.
Both meet that nominal capacity, without guaranteeing a specific maintenance interval.
What matters in practice
E25 refreshes its roller during use. Dreame cleans its rotating pads when they return to the station. That is a useful process choice for someone comparing roller and pad upkeep, but it cannot prove which leaves a particular floor cleaner without a matched test.
The E25 HydroJet description places washing in the mopping process. Dreame's DuoScrub and AceClean descriptions put rotary pads on the floor and pad washing at the dock.
A buyer requiring automatic detergent dosing can use the E25 function in this reviewed setup. L40 Ultra Gen 2 needs the separate dispenser module. A base-to-base comparison that ignores that accessory understates what the Dreame purchase must include for the same requirement.
The E25 station lists automatic detergent dispensing. Dreame's exact product disclaimer says the solution box is available separately, and the reviewed Amazon offer also specifies separate purchase.
Dreame's bag is 0.2 L larger, about 6.7% above E25's nominal three liters. That gives slightly more storage volume. Different debris, emptying frequency and test homes prevent converting it into a reliable replacement interval.
3.2 - 3.0 = 0.2 L. 0.2 / 3.0 × 100 = 6.67%. Manufacturer maximum-day claims use different conditions and are not compared.

eufy, Omni E25
The HydroJet roller keeps washing itself during a cleaning run. It provides the E28 floor-cleaning platform without a detachable spot cleaner.

Dreame, L40 Ultra Gen 2
An extending side brush and mop cover edges in a shorter body than the original L40. The newer generation gives up automatic mop removal.
Meaningful differences
| What changes | eufy Omni E25 | Dreame L40 Ultra Gen 2 | Why it matters |
|---|---|---|---|
| Mopping system | HydroJet roller | Two DuoScrub rotary pads | The floor-contact and replacement parts are different. |
| Mop washing process | Roller washed during use, plus station cleaning | Rotating pads washed at the station | This does not establish a measured stain-removal winner. |
| Edge hardware | CornerRover side arm | Extending side brush and extending mop pad | Dreame explicitly extends both the vacuum-side brush and a mop pad. |
| Main brush in reviewed base setup | DuoSpiral brushes | Rubber roller, TriCut optional | Check included hardware before assigning a cutting-brush advantage. |
| Automatic detergent dosing | Included dispensing function | Solution module purchased separately | Dreame's manufacturer bundles with a dispenser are different offers. |
| Station dust bag | 3 L | 3.2 L | The small volume difference does not establish days between changes. |
What you give up
Recommendation switch
Choose eufy Omni E25. E25 supplies that process.
Choose Dreame L40 Ultra Gen 2. Dreame supplies MopExtend and DuoScrub.
Choose neither. Neither robot combines these two different mopping systems.
What matters in practice
The clearest choice here is a washed roller versus rotating pads that return to the dock for cleaning. Think about replacement parts, access to the dirty-water path and the surfaces you mop. Avoid translating suction or scrubbing headlines into a winner for stains neither machine has been tested on here.
Dreame sells separate bundles with a TriCut brush and solution dispenser. Those pictures and bundle headlines cannot supply missing accessories to the linked base offer. If automatic dosing is a requirement, add the compatible module to the Dreame budget and follow the approved-solution instructions.
Both stations automate several jobs, but water tanks, brushes and cleaning trays still need attention. Detangling hardware does not remove inspection. Check your rugs and floor finish in the manual and use appropriate no-go or no-mop areas. A lifting mechanism alone cannot establish that every carpet remains dry.
