Hard-floor hair pickup is consistently praised, especially paired with the dual-roller design that avoids spreading clumps. Pet and human hair are typically collected cleanly into the bin.

Hair‑Wrap / Tangle Resistance
Product 1: Roborock QV 35A Robot Vacuum...
3.7

The anti-tangle design (rubber main brush and redesigned side brush) reduces snarls and makes maintenance easier, but it does not eliminate hair wrap entirely. At least one hands-on test still found noticeable wrap with very long hair.

Product 2: Roborock S8 + Robot Vacuum
4.6

Tangle resistance is a major highlight: the rubber dual rollers greatly reduce wrap and jamming. Hair may collect at roller ends, but removal is quick and doesn’t usually interrupt cleaning.

Hard Floor — Fine Dust Pickup
Product 1: Roborock QV 35A Robot Vacuum...
4.6

Fine debris like coffee grounds and small crumbs are reported to be picked up very effectively on hard floors, often with little left after a pass. Reviewers attribute this to strong suction and systematic pathing.

Product 2: Roborock S8 + Robot Vacuum
4.2

Hard-floor fine dust pickup is very strong, with tests showing high efficiency on smooth surfaces. Minor residual dust can remain near edges or in the middle of a test lane depending on pass patterns.

Hard Floor — Large Debris Intake
Product 1: Roborock QV 35A Robot Vacuum...

Mop pads can lift roughly 10 mm when carpet is detected, helping prevent wet rugs. This lift behavior is mentioned across multiple reviews and is treated as reliable and useful.

Product 2: Roborock S8 + Robot Vacuum
4.2

Mop lifting works well for mixed hard-floor and rug homes, reducing accidental wetting. The lift height isn’t the largest in the category, so very thick carpets may still benefit from avoidance settings.

Mopping performance
Product 1: Roborock QV 35A Robot Vacuum...
4.2

Dual spinning mops (around 200 RPM) deliver strong scrubbing for routine grime and many stains, with adjustable water flow and the benefit of an onboard tank. For big messes, some smearing can occur and the robot may need extra passes or a manual assist because it lacks advanced dirt-detection re-mop logic.

Product 2: Roborock S8 + Robot Vacuum
4.0

Mopping is better than many drag-pad hybrids thanks to sonic/vibration scrubbing, and it can handle light stains and surface grime. The common limitation is sticky/set-in messes and zone/edge precision, sometimes requiring multiple runs or a manual follow-up.

The robot is rarely reported as getting stuck, and reviewers note solid threshold handling and sensible no-go/avoidance tools. Messy floors (wires, socks) can still trigger occasional issues.

Suction and Airflow
Product 1: Roborock QV 35A Robot Vacuum...
4.3

Across reviews, 8,000 Pa suction is described as strong for the price and effective for day-to-day pickup on hard floors and rugs, with debris often cleared in one or two passes. Multiple reviewers say it performs similarly to pricier Roborock models in core vacuuming, but it still is not a full replacement for an upright on heavy carpet.

Product 2: Roborock S8 + Robot Vacuum
4.5

Reviews consistently praise strong pickup and suction, especially for routine dust and pet hair. A lab-style test notes deep-in-fiber and tight crevice extraction can lag behind the very best, even if overall cleaning remains strong.

Suitability for heavy-duty use
Product 1: Roborock QV 35A Robot Vacuum...
3.6

Reviews caution that, like most robot vacuums, it is best for maintenance cleaning rather than heavy-duty deep cleaning. Homes with lots of thick carpet or extreme debris still benefit from occasional full-size vacuuming.

Product 2: Roborock S8 + Robot Vacuum
No score yet
Support and Reliability
Product 1: Roborock QV 35A Robot Vacuum...
3.9

Under-furniture access is good for typical clearances, with multiple reviews showing it can clean beneath some furniture. Its height around 3.8 inches means very low furniture may remain out of reach.

Product 2: Roborock S8 + Robot Vacuum
No score yet
Water tank
Product 1: Roborock QV 35A Robot Vacuum...
4.4

The clean/dirty tank setup is considered convenient and easy to remove, and the robot also carries an onboard water tank that gets refilled at the dock. Multiple reviews warn the dirty tank can smell if left too long, so frequent emptying/rinsing helps.

Product 2: Roborock S8 + Robot Vacuum
3.8

The water tank approach works for routine wet cleaning, but several reviewers want an official cleaning-solution option and note tank capacity/cloth management can limit larger jobs. Users who pre-wet or refresh the pad mid-clean get better results.
