Mop lift is a major strength: multiple reviews cite high lift height that keeps carpets dry and allows confident vac-and-mop runs in mixed-floor homes.

Mopping performance
Product 1: Ecovacs Deebot X9 Pro Omni...
4.6

The self-washing roller mop is repeatedly called the standout feature, delivering strong scrubbing and excellent day-to-day hard-floor cleaning. A few tests found minor limitations (toe-kicks/appliances it can’t slide under, or slight stickiness/residue on messy stress tests), but it still ranks among the best.

Product 2: Roborock S8 MaxV Ultra Robot...
4.1

Mopping is generally strong for a pad-based system (hot-water washing, vibration, and smart re-mopping help), but some comparison tests still place it behind the very best spinning/roller-style moppers on heavy stains.

Noise level
Product 1: 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.

Product 2: Roborock S8 MaxV Ultra Robot...
4.4

Reviews consistently highlight strong suction (often cited as 10,000Pa) and above-average carpet results, though one lab-style test found it did not dominate fine sand and some hard-floor debris can get pushed around by the side brush.

Under-Furniture Pickup
Product 1: 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.

Product 2: Roborock S8 MaxV Ultra Robot...
4.3

Under-furniture reach benefits from the extending side brush and slimmer edge access, helping capture debris along toe-kicks and under some appliances.

Water tank
Product 1: 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.

Product 2: Roborock S8 MaxV Ultra Robot...
4.4

Clean/dirty tank capacity and usage rate are viewed as competitive; some comparisons suggest it can go longer between water changes than many rivals, though frequency still depends on home size and mopping schedule.
