The short answer

iRobot Braava Jet M6 comes out ahead by a narrow margin (4.3 vs 4.0). The gap is mostly about iRobot ecosystem owners who already have a Roomba and want Imprint-Link coordinated mopping, hard-floor-dominant homes that want a small, low-clearance mop separate from their main vacuum — read the strengths below before deciding.

The Braava Jet M6 is the only dedicated mop in this draft, here for the narrow audience that wants a true mop-only robot, often as a companion to a Roomba vacuum. Its Precision Jet spray and Imprint Smart Mapping are still well executed. iRobot's late-2025 bankruptcy filing leaves the long-term software-support story uncertain, so buy with that caveat in mind.

Strengths
  • Imprint Smart Mapping covers up to 1,000 sq ft in one trip and remembers per-room cleaning preferences
  • Precision Jet Spray targets the floor in front of the robot for damp mopping that doesn't oversaturate sealed wood
  • Imprint Link technology pairs it with a Roomba to run mopping after the Roomba finishes vacuuming
Watch-outs
  • Mop-only — no vacuum capability, so it pairs best with a separate Roomba
  • iRobot filed Chapter 11 in late 2025; the brand is being acquired and post-2026 software support is uncertain
  • Amazon customer rating has slipped to 3.07/5 reflecting mixed reliability reports
Roborock S8 Pro Ultra
Ranked #3 in Best Robot Mops
Roborock S8 Pro Ultra
3 sources1 derived$580as of May 26

As the previous-generation Roborock flagship, the S8 Pro Ultra remains the pick when mopping is the priority and you'd rather have a vibrating sonic pad than a spinning one. Vacuum Wars saw 'some of the best results we've seen so far' on dried-on mopping tests. Newer competitors have eclipsed its suction, but in hard-floor-dominant homes the trade-off favors the mop.

Strengths
  • VibraRise 2.0 sonic mop pad vibrates at thousands of strokes per minute and pulls dried-on stains the spinning-pad designs leave behind
  • Mop pad auto-lifts 5 mm to clear short carpets so a single cycle handles both surfaces without re-runs
  • RockDock Ultra empties the bin, washes pads, dries them with warm air, and refills the water tank with no user touch
Watch-outs
  • 6,000 Pa suction is now mid-pack as flagship rivals push past 10,000 Pa
  • Sonic mop pad cannot extend to the very edges of baseboards — no FlexiArm equivalent
  • RockDock Ultra is one of the larger docks in the category at 17.7 in tall

Derived means the reviewer published no score, so one was inferred from their written verdict. Everything else is a number the publisher printed. How we rank.

How they stack up

iRobot Braava Jet M6

The only dedicated mop in this draft — the Roborock Qrevo Master, Roborock S8 Pro Ultra, Eufy X10 Pro Omni, and Bissell SpinWave R5 are all combo vacuum-mop units. Best suited as a companion to a separate Roomba rather than as a standalone cleaner.

Roborock S8 Pro Ultra

Sonic vibrating pad lifts dried stains better than the Qrevo Master's spinning pads, but the Qrevo Master beats it on suction and edge-cleaning. The Eufy X10 Pro Omni is now a stronger value pick than the S8 Pro Ultra unless you specifically want the sonic mop.
