Mopping: refreshed roller or better edge reach?
Mop-cleaning workflow, simplified. Dreame’s hot-water wash takes place at the dock.
The E25 feeds water to its HydroJet roller and scrapes away dirty water as it works. The Dreame scrubs with two pads, extends one toward edges, and returns to the dock for washing. Its hot-water wash cleans the pads at the station; it is not steam cleaning your floor.
In TechRadar's two-week E25 test, liquid spills cleaned well. Dried ketchup needed stronger manual settings and repeated passes, and edges still needed attention. That supports choosing it for routine kitchen upkeep, not expecting every dried stain to disappear automatically.
Pet hair and carpets: brushes matter more than Pa
Eufy's DuoSpiral brushes split to release tangled hair. Dreame's linked standard model uses a rubber brush; the hair-cutting TriCut brush is an optional purchase. For a shedding pet, compare brush maintenance and replacement costs rather than assuming Dreame's claimed 25,000 Pa beats Eufy's claimed 20,000 Pa.
Both lift their mops over carpet, but neither automatically leaves its mop at the dock. Dreame specifies 10.5 mm of lift. That is not a guarantee against damp thick rugs: use carpet avoidance where necessary. Eufy's manual warns against high-pile rugs and rugs thicker than 21 mm.
Obstacles and furniture: plan around your actual home
Heights from Eufy’s user guide and Dreame’s US specifications. Blocks show height only, not product shape.
The E25 has camera-based recognition; Gen 2 uses structured-light sensing without an RGB camera. TechRadar's E25 avoided staged obstacles but dragged a charging cable during everyday use. Clear cords and check for pet accidents before running either robot unattended.
Dreame's lower body may reach under furniture the E25 cannot. Measure the lowest clearance, allowing extra room rather than matching the robot height exactly. We found no reliable head-to-head measurements for this exact pair, so we cannot name a proven obstacle-avoidance or carpet-pickup winner.
Dock maintenance: less daily work, not zero work
Automation reduces chores; water tanks, trays, brushes and filters still need attention.
Both stations empty dust, wash and dry the mop, and refill the robot. You still refill the station's clean-water tank, dispose of dirty water and clean the tray, filters and brushes. Dreame's manual specifies cleaning its used-water tank after each use; Eufy recommends regular emptying and cleaning, with drying after mopping.
Dreame's 4.5-litre clean-water tank is larger than Eufy's 2.5-litre tank, potentially reducing refills for the same water use. It takes more vertical space: the official specifications give dock heights of 590 mm and 436 mm respectively. Allow space above either dock to lift out its tanks.
Budget for bags, filters, mop parts and approved cleaning solution. Dreame's automatic solution dispenser is not included by default; verify any advertised bundle.
Which should you buy?
Buy the E25 if regular hard-floor mopping and detangling brushes matter most. Buy the Dreame if edge reach, low furniture and vacuum-then-mop control fit your home better. A substantial discount can change the value calculation; compare the exact bundle and ongoing consumables before paying more.
Amazon may redirect these links to a local listing. Confirm the exact model, dock voltage, delivery and warranty. The E25 guide distinguishes US and 220–240 V versions; Dreame's US Gen 2 manual specifies a nominal 120 V circuit. A plug adapter alone does not solve a voltage mismatch.

Research notes
This comparison covers the linked Black E25 and Black L40 Ultra Gen 2. The original L40 Ultra, L40s Ultra and Eufy E28 have different features. Decively has not tested these robots; independent findings are attributed above.
Research checked 11 October 2026. Sources: Eufy E25 documentation, Dreame L40 Ultra Gen 2 documentation and Steve Clark's TechRadar E25 review. This is a researched buying comparison; Gen 2 is not an across-the-board upgrade over the original L40 Ultra. Full source addresses are retained in Decively's research record.
