Qrevo Curv vs Roomba Combo j9+
How these two compare on everything we measure — where the AIs rank them, what reviewers and buyers say, and how they price. The differences are the point — they decide which one is yours.
Side by side
Every signal we hold, on one shared scale. The leading side is lit — and where the AI panel and the reviewers pull apart, the row says so.?
Built from what 2 AI models (ChatGPT · Perplexity) recommend for real buyer questions, layered with reviewer test summaries, Google buyer ratings, street prices and press. The short answer and verdict are derived from where those signals diverge — not written by hand for either product.

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