Ecovacs Deebot X2 Omni vs Dreame L40s Ultra AE
Quick take: The Dreame L40s Ultra AE costs $50 less; the Dreame L40s Ultra AE has stronger suction (19,000 vs 8,000 Pa); the Ecovacs Deebot X2 Omni runs longer per charge (212 vs 180 min).
Which one to buy
Corners are the whole case for the Ecovacs Deebot X2 Omni, which is now discontinued (Ecovacs' replacement is the Deebot X9 Pro Omni at $800). It's square, and its owners agree on one thing above all: it reaches into corners and along edges that round robots leave dirty. If your rooms are full of built-ins, cabinets and tight angles, that's a real reason to hunt down leftover stock.
For almost everything else, the Dreame L40s Ultra AE is the better robot, at $600, $50 less than the X2's last price. It's rated at 19,000 Pa against the X2's 8,000 Pa, carries a 3-year warranty against 2 years, and its owners and testers point to an 85% carpet deep-clean score, obstacle avoidance of 19 out of 24 objects, and battery efficiency good for roughly 2,462 sq ft on a charge. Its mopping left the least water behind of its trim family while still lifting stains.
The X2's complaints are well worn. Owners call the Ecovacs app the most criticized part of the experience, with dropped connections, crashes and slow map loading, though it has improved. They also say the square body catches on chair legs, the 70 dB suction is louder than Dreame and Roborock flagships, its dock is loud and slow, and its hot-water wash comes out lukewarm. Past camera security concerns still come up.
The L40s Ultra AE gives some things up. It has no extending side brush and no threshold-climbing lift, so high transitions are harder for it, and its flattened pet-hair pickup tested at 81%. Make sure you're buying the AE trim, since Dreame sells similar names with weaker obstacle hardware.
Ecovacs Deebot X2 Omni
Now discontinued, but go this way if dirty corners and edges are your main frustration with round robots and you can live with a louder machine and a weaker app.
Dreame L40s Ultra AE
Choose it if you want stronger suction, better obstacle avoidance and a 3-year warranty for $50 less than the X2's last price, and your home doesn't have tall thresholds.

Ecovacs Deebot X2 Omni vs Dreame L40s Ultra AE: common questions
Does the X2 Omni's square shape make up for its lower suction?▾
Only if corners are what you care about. Owners agree the square body cleans corners better than any round robot, but its 8,000 Pa rating is well below the L40s Ultra AE's 19,000 Pa, and the Dreame tests strongly on carpet. In open rooms the Dreame is the better cleaner.
Which is better around cords, toys and pet mess?▾
The L40s Ultra AE. Testing scored it 19 out of 24 on obstacle avoidance, a big step over the other L40s trims. X2 owners say its AIVI 3D system handles most common objects, but the square shape also tends to snag on chair legs.
How do I make sure I get the right L40s Ultra trim?▾
Check for "AE" in the name. Dreame sells the plain L40s Ultra and Ultra CE under similar names, and owners note those trims scored far lower on obstacle avoidance in testing, at 7 and 8 out of 24.
