The catch
eufy Omni E25
Dreame's extending rotary mop pad is not part of the roller system.
Side by side
eufy Omni E25 vs Dreame L40 Ultra Gen 2 guide: Dreame’s module is optional, while detergent dosing is included with E25
Quick verdict
Omni E25 is the choice if you want a roller washed during use and automatic detergent dispensing in the reviewed base setup. L40 Ultra Gen 2 is the choice if you would rather have two rotating mop pads with physical extension and a separately extending side brush. The Dreame solution module and TriCut brush are optional, so compare the actual package before you treat them as included.
Before you buy
Why, and what it costs you
Where the dirty textile gets refreshed depends on the mopping method
During use, E25 refreshes its roller, while Dreame cleans its rotating pads once they are back at the station. For someone comparing roller and pad upkeep that is a useful process choice, but without a matched test it cannot prove which one leaves a particular floor cleaner.
Where this comes from
In the E25 HydroJet description, washing is part of the mopping process itself. Dreame's DuoScrub and AceClean descriptions have rotary pads on the floor and pad washing at the dock.
The catch
Dreame L40 Ultra Gen 2
A separately purchased module is needed for automatic solution dosing.

In practice
Differences you will notice
Where the dirty textile gets refreshed depends on the mopping method
During use, E25 refreshes its roller, while Dreame cleans its rotating pads once they are back at the station. For someone comparing roller and pad upkeep that is a useful process choice, but without a matched test it cannot prove which one leaves a particular floor cleaner.
How we worked this out
In the E25 HydroJet description, washing is part of the mopping process itself. Dreame's DuoScrub and AceClean descriptions have rotary pads on the floor and pad washing at the dock.
The complete-package comparison shifts once automatic dosing is counted
In this reviewed setup, a buyer who requires automatic detergent dosing can use the E25 function, whereas L40 Ultra Gen 2 needs the separate dispenser module. Comparing base to base while ignoring that accessory understates what the Dreame purchase must include to meet the same requirement.
How we worked this out
Automatic detergent dispensing is listed for the E25 station. Dreame's exact product disclaimer says the solution box is available separately, and the reviewed Amazon offer likewise specifies a separate purchase.
Advertised day counts suggest a bigger bag difference than there really is
At 0.2 L larger, Dreame's bag is about 6.7% above E25's nominal three liters, which gives slightly more storage volume. Because debris, emptying frequency and test homes differ, that cannot be converted into a reliable replacement interval.
How we worked this out
3.2 - 3.0 = 0.2 L. 0.2 / 3.0 × 100 = 6.67%. The manufacturers' maximum-day claims rest on different conditions, so they are not compared.
Option A
eufy, Omni E25
Omni E25
The HydroJet roller washes itself throughout a cleaning run. It is the E28 floor-cleaning platform with the detachable spot cleaner left off.
- Best for
- HydroJet roller washing during the mopping run
Facts we checked
- Mopping system: HydroJet roller
- Mop washing process: Roller washed during use, plus station cleaning
- Edge hardware: CornerRover side arm
- Main brush in reviewed base setup: DuoSpiral brushes
Option B
Dreame, L40 Ultra Gen 2
L40 Ultra Gen 2
Edges are covered by an extending side brush and mop, and the body is shorter than the original L40's. What the newer generation gives up is automatic mop removal.
- Best for
- Removable rotating pads with MopExtend reach
Facts we checked
- Mopping system: Two DuoScrub rotary pads
- Mop washing process: Rotating pads washed at the station
- Edge hardware: Extending side brush and extending mop pad
- Main brush in reviewed base setup: Rubber roller, TriCut optional
Spec by spec
Where they really differ
| Spec | eufy Omni E25 | Dreame L40 Ultra Gen 2 | In practice |
|---|---|---|---|
| Mopping system | HydroJet roller | Two DuoScrub rotary pads | Floor-contact parts and replacement parts are not the same. |
| Mop washing process | Roller washed during use, plus station cleaning | Rotating pads washed at the station | No measured stain-removal winner follows from this. |
| Edge hardware | CornerRover side arm | Extending side brush and extending mop pad | On Dreame, both the vacuum-side brush and a mop pad explicitly extend. |
| Main brush in reviewed base setup | DuoSpiral brushes | Rubber roller, TriCut optional | Before crediting either with a cutting-brush advantage, check the included hardware. |
| Automatic detergent dosing | Included dispensing function | Solution module purchased separately | The bundles from Dreame's manufacturer that come with a dispenser are separate offers. |
| Station dust bag | 3 L | 3.2 L | Days between changes cannot be drawn from the small volume difference. |
Trade-offs
What each pick costs you
With eufy Omni E25
- You still have to maintain the roller and the dirty-water path.
With Dreame L40 Ultra Gen 2
- Rubber is the base brush, and TriCut is optional.
Change of plan
When the answer changes
Roller washing has to happen during floor cleaning
Go with eufy Omni E25. That process comes from E25.
Rotating mop pads that physically extend are essential
Go with Dreame L40 Ultra Gen 2. MopExtend and DuoScrub come from Dreame.
You need a washed roller and an extending rotary mop pad together
Neither model fits. These two different mopping systems are not combined in either robot.
Decision guide
How to decide
Start by picking the floor-contact mechanism
The clearest choice here is between a washed roller and rotating pads that go back to the dock for cleaning. Consider replacement parts, access to the dirty-water path and the surfaces you mop. Do not turn suction or scrubbing headlines into a winner on stains that neither machine has been tested on here.
Put a price on the exact base configuration
Separate Dreame bundles come with a TriCut brush and solution dispenser. Their pictures and headlines cannot supply missing accessories to the linked base offer. If you require automatic dosing, add the compatible module to the Dreame budget and follow the approved-solution instructions.
Stay realistic about maintenance and rug handling
Several jobs are automated by both stations, yet water tanks, brushes and cleaning trays still need attention, and detangling hardware does not remove the need to inspect. Look up your rugs and floor finish in the manual and set suitable no-go or no-mop areas. A lifting mechanism alone cannot establish that every carpet stays dry.
What this page can’t tell you
- No head-to-head test of debris, hair, stains, noise or hygiene was performed. The comparison rests on documented hardware and maintenance processes.
- No advantage in hot-water washing or in going camera-free is claimed. Manufacturer comparison material contains model-dependent wording, so those details are left out of this decision.
