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).

Dreame L20 Ultra
