Stuck resistance
Product 1: DREAME L40s Ultra Robot Vacuum...
3.2

Stuck events are not eliminated—small cords, socks, and toys can still snag the robot in some homes—though others report mostly hands-off runs once no-go zones are set.

Product 2: Ecovacs Deebot X9 Pro Omni...
3.6

Reports vary from near trouble-free operation to frequent help alerts depending on home layout. Thresholds and odd obstacles can cause wedging or debris drops in some tests, while careful mapping/no-go zones improves reliability for others.

Suction and Airflow
Product 1: DREAME L40s Ultra Robot Vacuum...
4.5

Reviews consistently describe very strong pickup on both hard floors and carpet, with high advertised suction translating to real-world debris removal; one benchmark notes airflow can test below average despite the strong cleaning results.

Product 2: Ecovacs Deebot X9 Pro Omni...
4.6

Most reviews describe very strong pickup driven by Ecovacs’ BLAST airflow approach, with top-tier results on both hard floors and carpet. A few reviewers say the real-world improvement over the X8 is modest and that large debris can still trigger drops or clogs.

Under-Furniture Pickup
Product 1: DREAME L40s Ultra Robot Vacuum...
No score yet
Product 2: Ecovacs Deebot X9 Pro Omni...
3.7

The internal LiDAR approach avoids a tall turret and helps it reach under more furniture than tower-based bots. Still, reviewers note the roller mop can’t slide under some low-clearance areas the way flat pads can.

Water tank
Product 1: DREAME L40s Ultra Robot Vacuum...
4.3

Large clean/dirty water tanks are a recurring plus for longer intervals between refills/emptying, though you still need to swap water on a regular schedule.

Product 2: Ecovacs Deebot X9 Pro Omni...
4.1

The clean/dirty tank setup is commonly described as easy to use, but there are tradeoffs: some miss transparent or externally visible tanks, some describe smaller/hidden tanks requiring more frequent refills, and dirty tanks can have corners that trap grime.
