Under-Furniture Pickup
P1
Product 1: Roborock Saros 20
4.8
Under-furniture pickup was consistently praised because the low body can reach and clean under sofas, beds, counters, and cabinets.

Product 2: Dreame X60 Max Ultra
5.0
Under-furniture pickup is a standout strength due to the low-profile body and retractable LiDAR letting it reach spaces other robots miss.
Value-for-money

3.5
Value-for-money depends on home complexity: reviewers liked the flagship capability but often warned simpler homes can spend less.

Product 2: Dreame X60 Max Ultra
2.5
Value-for-money is mixed to weak because strong performance is offset by repeated concern about premium pricing.
Versatility

4.6
Versatility is strong across mixed flooring, carpets, hard floors, vacuuming, mopping, rooms, zones, routines, and smart-home use.

Product 2: Dreame X60 Max Ultra
4.5
Versatility is well-supported by evidence that it handles vacuuming and mopping across hard floors, carpets, tile, and hardwood in one run.
Water tank

3.9
Water-tank feedback was mostly easy and functional, though one reviewer noted a missing max-fill line and another noted tank-size changes.

3.4
Water-system evidence is mixed: the dock has clean and dirty tanks, but some reviewers mention smaller tanks or refilling hassle.
Weight

3.7
Weight was only directly mentioned once; the heft was framed as useful for mopping pressure rather than portability.

2.5
Weight is a drawback in the one review that directly mentions 51.9 pounds affecting portability.
