A standout feature in the video reviews is the dock’s dirt-detection logic that can trigger a remopping event after the robot washes its pads. Reviewers note it may require enabling in the app, and they credit it with improving results on dirtier zones after the first pass.

Docking and Auto-Empty Reliability (Robot)
Product 1: iRobot Roomba J5+ Combo Vacuum...
3.8

The self-empty base is a major convenience when vacuuming, with multi-week capacity in a disposable bag. Multiple reviewers also note limitations when the mop bin is installed (auto-empty may be blocked) and describe the docking/empty cycle as very loud.

Product 2: Roborock Qrevo Curv S5X Robot...
4.6

The multifunction dock is repeatedly described as the product’s key value: bagged auto-empty, mop washing with heated water, mop drying with warm air, and water refilling to keep hands-on effort low. Reliability feedback is strongly positive overall, with the auto-empty step being quick but louder.

Dock noise
Product 1: iRobot Roomba J5+ Combo Vacuum...
1.7

Auto-emptying noise is repeatedly called out as loud (some describe it as jet-engine level), with docking/emptying being the most disruptive part compared to typical cleaning operation.

Product 2: Roborock Qrevo Curv S5X Robot...

Mop lifting system
Product 1: iRobot Roomba J5+ Combo Vacuum...
1.3

The j5+ does not provide a true mop lifting/retracting system; multiple reviews emphasize you must manage carpets with no-mop zones and careful room selection, and that premium Roombas (e.g., higher combos) handle this more automatically.

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

Mop lifting is consistently cited around a 10 mm lift when carpet is detected, enabling mixed vacuum+mop routines with reduced risk of wetting rugs. Reviews describe this as effective for typical transitions, though very plush carpets and small mats can still be problematic for navigation.

Mopping performance
Product 1: iRobot Roomba J5+ Combo Vacuum...
3.0

Mopping is widely characterized as light-duty: more of a wet-pad wipe than a scrub. Some tests show decent results on certain stains, but several reviewers found it underpowered for dried-on messes and lacking features like vibration/scrubbing and strong pressure.

Product 2: Roborock Qrevo Curv S5X Robot...
4.6

Mopping performance earns strong praise, especially in video tests cleaning muddy paw prints and in written reviews describing time savings versus manual mopping. The dock’s wash-and-dry process plus optional remopping is credited with keeping results consistent over time.

Noise level
Product 1: iRobot Roomba J5+ Combo Vacuum...

Suction and Airflow
Product 1: iRobot Roomba J5+ Combo Vacuum...
No score yet
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: iRobot Roomba J5+ Combo Vacuum...
3.0

Support and reliability signals are mixed: iRobot’s pet-accident avoidance promise and established ecosystem are viewed positively, but some users report needing customer service help to activate the mop bin properly and express frustration with documentation clarity.

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: iRobot Roomba J5+ Combo Vacuum...
No score yet
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.

Water tank
Product 1: iRobot Roomba J5+ Combo Vacuum...
2.6

The mop module uses a small tank (often cited around 210ml/7oz) and requires manual fill. Several reviews warn it can seep/leak once filled and recommend filling only when ready to run, plus removing/storing the mop bin after use.

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

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.
