What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
iRobot Roomba j9+
Only one whitelisted tester (TechHive) reviewed the exact vacuum-only Roomba j9+, hands-on with no lab bench numbers; it earned Editors' Choice for strong cleaning and obstacle avoidance. Other major reviews (Tom's Guide, TechRadar, Engadget) cover the mop-hybrid Combo j9+, a different config, so were excluded here. (1 sourced review.)
Praised: Excellent obstacle detection and avoidance, including pet waste; Strong vacuuming pickup, including heavy pet hair without roller tangling; Dirt Detective prioritizes the dirtiest rooms automatically.
Flagged: PrecisionVision navigation depends on ambient light (won't clean in the dark); Many app controls buried in sub-menus.
