What the differences mean
Suction, runtime, warranty
The Dreame L40 Ultra Gen 2 is rated at 25,000 Pa and 231 minutes, with a 3 year warranty and about 3.5 hours to charge. The Eufy E25 is rated at 20,000 Pa and 216 minutes, with a 1 year warranty and about 3.5 hours to charge. Both return to the dock. The gaps are small on runtime and clear on warranty and on the 5,000 Pa step. Noise on the Dreame L40 Ultra Gen 2 is not documented. The Eufy E25 is rated at 57 dB.
Tanks and bins
The Dreame L40 Ultra Gen 2 holds 4.5 L of water and a 3.2 L dock bin, with 250 ml onboard. The Eufy E25 holds 2.5 L of water and a 3 L dock bin, with 300 ml onboard. Both self-empty, both dose detergent and both wash and dry the mop. The Dreame L40 Ultra Gen 2 stores more water and more dust at the dock. The Eufy E25 stores more on the robot between empty cycles.
Smart home now
The Eufy E25 lists Alexa, Google Home, Apple HomeKit, SmartThings, Home Assistant and Matter as supported, and it has Bluetooth. The Dreame L40 Ultra Gen 2 lists Alexa and Google Home now, has no Bluetooth, and lists Apple HomeKit, SmartThings, Home Assistant and Matter as an upcoming update. Neither has 5 GHz Wi-Fi. If Matter has to work the week the robot arrives, the Eufy E25 is the one that lists it.
Height
The Dreame L40 Ultra Gen 2 stands 97 mm tall. The Eufy E25 stands 111 mm tall, and owners say the laser turret on top is what catches under low furniture. Both use LiDAR, both set no-go zones and both lift the mop for carpet. The shorter body is the Dreame L40 Ultra Gen 2. That is a separate reason from suction to prefer it in a home full of sofas.

What owners say
Owners of the Dreame L40 Ultra Gen 2 and the Eufy E25 both say the station is why they stopped mopping by hand, and both mention pet hair. Dreame L40 Ultra Gen 2 owners single out an extendable brush in corners and maps on more than one floor, and they complain that hair can wrap a wheel and that the app takes time to learn. A few lost a mop pad mid-run. Eufy E25 owners single out hair pickup and a station that refills water, and they complain the roller dampens more than it scrubs, that the raised laser turret snags under low furniture, and that the mop and the dirty tank need cleaning or they smell. Edges are the shared leftover chore, described more sharply on the Eufy side.
