What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
iRobot Braava Jet m6
Three whitelisted testers (Tom's Guide, Reviewed, TechHive) went hands-on with the Braava Jet m6 and agree it is the best hard-floor robot mop they had tested, praising accurate vSLAM mapping with keep-out/clean zones and effective grime pickup on bare floors. Two flag the ~$400 price. TechHive highlights automatic carpet recognition, while Tom's Guide instead had to fence off area rugs with keep-out zones. Reviews date to 2019-2020. (3 sourced reviews, 3 lab-tested.)
Praised: Accurate vSLAM mapping with keep-out/clean zones; Effective hard-floor cleaning that lifts real grime; Tandem 'linked' cleaning in sequence with select Roomba vacuums.
Flagged: Expensive (~$400); Proprietary, model-specific pads and cleaning solution; Slow smart-map setup (hours / multiple runs).
Roborock S8 MaxV Ultra
Two whitelisted hands-on reviews survived verification (TechRadar and TechHive); both testers used the robot. They agree it is a strong-but-pricey flagship with excellent suction, quick and accurate mapping, and an intuitive app, but only mixed/decent mopping. TechHive measured about 95 percent hard-floor and 100 percent carpet rice pickup and a roughly 10-minute whole-home map. TechRadaR and TechHive split on voice-assistant and cable/obstacle reliability. (2 sourced reviews, 2 lab-tested.)
Praised: Strong vacuuming and suction; picks up debris well on hard floors and carpet; Intuitive, well-designed Roborock app; Quick, accurate mapping.
Flagged: Mopping only mixed/decent — not its strength; Very expensive premium price; Small onboard dustbin and water tank; not ideal for very large homes.
