Noise level
Product 1: Roomba Combo j9+ Robot Vacuum...
3.8

Noise is a mixed bag: in-room vacuuming is often described as noticeable but tolerable, while auto-emptying can be loud for some. A few reviewers found the empty cycle quieter than other robots, but others measured/mentioned it as disruptive.

Product 2: Roborock Qrevo Curv S5X Robot...
4.3

Noise is described as relatively low during mopping at lower water flow and acceptable during standard vacuuming. The loudest moments tend to be MAX+ suction and the brief auto-empty cycle at the dock, which reviewers note is quick.

Obstacle Avoidance (Robot)
Product 1: Roomba Combo j9+ Robot Vacuum...
4.6

Obstacle avoidance is a defining strength: the camera-based system reliably dodges cords, toys, shoes, and pet waste in most tests, and often outperforms rival bots in clutter. It’s not flawless, but it dramatically reduces stuck events and accidental messes versus non-vision robots.

Product 2: Roborock Qrevo Curv S5X Robot...
3.5

Obstacle avoidance is described as good for larger items (like toys, shoes, or furniture legs), but cables remain a clear weakness where the robot may snag or run them over. Compared with camera-based variants, reviewers suggest avoidance is slightly reduced, making pre-tidying important.

Odor control
Product 1: Roomba Combo j9+ Robot Vacuum...
No score yet
Product 2: Roborock Qrevo Curv S5X Robot...
4.3

Hot-air drying at the dock is repeatedly credited with reducing mop-pad odor and mold risk. Some reviewers still note dirty-water tank smell can be unpleasant if neglected, and suggest regular emptying (and optional deodorizing tricks) as part of ownership.

Ongoing ownership costs (bags, filters, batteries)
Product 1: Roomba Combo j9+ Robot Vacuum...
3.7

Ongoing costs are a real factor: bags, filters, brushes, and occasional pads add recurring spend. The upside is the bagged system is clean and parts are widely available, but budget-minded buyers should plan for replenishment.

Product 2: Roborock Qrevo Curv S5X Robot...

Streaking / Residue
Product 1: Roomba Combo j9+ Robot Vacuum...
4.0

Residue and streaking are usually minor, but some reviewers notice occasional streaks or sticky patches after messy tests like jam/jelly. Regular pad washing and appropriate water/solution settings help reduce visible streaking.

Product 2: Roborock Qrevo Curv S5X Robot...
4.0

On heavier wet messes, reviewers note that a first pass can leave minor smearing, but the system’s remopping logic and/or two-pass patterns substantially reduce residue. For typical maintenance mopping, overall feedback remains strongly positive.

Stuck resistance
Product 1: Roomba Combo j9+ Robot Vacuum...
3.9

Stuck events are infrequent once maps and keep-out zones are tuned, but the robot can still snag on bath mats, high-pile rugs, tight gaps, or situations where the mop arm can’t retract cleanly. Overall, it improves after the first few runs.

Product 2: Roborock Qrevo Curv S5X Robot...
3.1

Stuck events are most often tied to loose cables and small/lightweight rugs or bath mats. Reviewers recommend pre-tidying cords and managing small mats to improve reliability, and some note that aggressive crevice/edge extensions can increase snag risk in cord-heavy areas.

Suction and Airflow
Product 1: Roomba Combo j9+ Robot Vacuum...
4.5

Across reviews, suction is a standout: strong pickup on hard floors and carpet, with smart boost behavior and fewer repeat passes than older Roombas. A few testers still rate raw power a step behind the most aggressive premium competitors, but most call it top-tier for daily debris.

Product 2: Roborock Qrevo Curv S5X Robot...
4.4

Reviews consistently describe strong suction (often cited around 17,000 Pa) with impressive hard-floor pickup and generally good carpet vacuuming for a robot. Turbo/MAX modes improve pickup but raise noise, so many users rely on extra passes instead of always running at max.

Support and Reliability
Product 1: Roomba Combo j9+ Robot Vacuum...
3.6

Reliability feedback is mostly positive over weeks of use, but a few reviews mention glitches (unfinished jobs, mode misbehavior) and at least one report of a defective unit that required replacement. Keeping receipts for early runs is commonly advised.

Product 2: Roborock Qrevo Curv S5X Robot...
3.6

Support impressions vary by channel, with at least one reviewer preferring to purchase through Amazon for smoother returns and warranty handling. Brand support is described as better than some competitors, but not always seamless, so retailer-based support is seen as a practical hedge.

Under-Furniture Pickup
Product 1: Roomba Combo j9+ Robot Vacuum...
4.4

Under-furniture reach is good thanks to the low profile and persistent navigation, with multiple reviewers noting it cleans under beds, desks, and tables. Very low clearances still depend on your furniture height.

Product 2: Roborock Qrevo Curv S5X Robot...
4.2

Under-furniture access is generally good as long as clearance meets the robot’s height, with reviews citing it can clean under many sofas and cabinets. The LiDAR turret means ultra-low furniture can still be a limitation, so low-clearance zones may need no-go rules.

Auto-fill dock is a major convenience, with many citing weeks of mopping before refills in average use. A few find the reservoir awkward to handle/refill, but the concept and day-to-day automation score highly.

The clean/dirty water tank system is frequently described as convenient, with reviewers citing generous capacities (for example, 4 L clean and 3 L dirty in one review) and automatic refilling of the robot’s internal tank. Users still need to periodically refill and empty tanks, especially in heavy mopping households.
