Distilled from the video reviewers — the score, what they praise, where they push back.?

Qrevo Curv
across 5 reviews
3.5/5
divided
Reviewers praise
  • Dual-brush 'Duo Divide' roller resists hair tangles exceptionally well, including pet and long human hair, with multiple reviewers finding the rollers clean after full runs
  • Spinning mop pads clean hard floors thoroughly, and the dock's hot-water mop-pad washing, warm-air drying, and self-cleaning base reduce manual maintenance significantly
  • Navigation is fast and efficient, covering large floor plans quickly with strong battery endurance
Reviewers push back
  • Obstacle avoidance is inconsistent — the robot regularly plows into shoes, fake animal waste, and cords, and the adapt lift feature can pull cables deeper into the brush system rather than avoiding them
  • High-pile carpet cleaning is weaker than low-pile or hard floors; the split brush design reduces downward pressure, and enabling Adapt Lift on medium-pile carpet further hurts deep cleaning
  • Cord management is a recurring reliability problem; multiple reviewers experienced sessions ending prematurely because a cord jammed the machine
A capable robot vacuum-mop with genuinely impressive hair-tangle resistance, fast navigation, and a well-engineered dock, undermined by inconsistent obstacle avoidance and a tendency to jam on cords.
— best for: Buyers with mostly hard floors or low-pile carpet, pets that shed heavily, and homes with problematic thresholds will get the most from this robot.

4.0/5
divided
Reviewers praise
  • Exceptional vacuuming power — dual rubber brushes and high suction handle fine debris, large debris, and deeply embedded carpet dirt better than most robot vacuums reviewers have tested
  • Auto-retract mopping system lifts the pad fully onto the robot's back over carpet, reliably keeping carpets dry while vacuuming and mopping in a single pass
  • Smart Scrub feature uses downward pressure and back-and-forth passes to remove dried-on stains more effectively than simple drag-pad designs
Reviewers push back
  • No automatic mop-pad washing or drying at the dock; pads must be removed and hand-washed after each mopping run
  • Navigation is slower than key competitors — initial mapping takes longer and cleaning runs average noticeably more time per session
  • Filters cannot be washed and become heavily soiled faster than the claimed maintenance interval suggests, adding ongoing replacement cost
A genuinely strong vacuum-mop combo with class-leading suction and a clever mop-retract system, held back by slow navigation, no auto mop-pad washing, and a few app rough edges.
— best for: Households with a mix of hard floors and carpet that want the most thorough vacuuming performance available in a robot combo unit and are willing to hand-wash the mop pad in exchange for a sanitary, low-odor dock.
Reviewers disagree · Qrevo Curv?
Vacuum Wars 4.5/5
The French Glow 2.0/5

Suction improvement over prior models is disputed: Vacuum Wars found carpet deep-clean scores meaningfully better than predecessors, while Just Josh noticed no practical difference in suction performance day-to-day

Reviewers disagree · Roomba Combo j9+?
Vacuum Wars 4.5/5
Erin Lawrence 3.5/5

Sanitary trade-off: Vacuum Wars and Erin Lawrence accept iRobot's argument that skipping auto pad-washing avoids dirty-water odor and debris mixing, while Vacuum Chef frames the omission as an oversight given a newer sibling model now includes the feature

Just take the leap. This thing is so much better than the 4 other iRobot devices I have had. I wish I had done it sooner. Super easy set up, very functional app, and my floors are SO clean after one run. Grab it while it is on sale. You absolutely will not be disappointed. For reference, I have two dogs, one of which is a medium shedder, but they both come in with muddy paws. This vacuum and mop i Cococarr · Target

Easy setup- love the mop and vacuum combo. Does a fabulous job of hard and carpet floors. Quiet- other than when it empties its bin. Really user friendly technology. So far can’t fault it myer.com.au
