Obstacle Avoidance (Robot)
Product 1: Roborock QV 35A Robot Vacuum...
3.9

Reactive tech obstacle avoidance is generally good for larger items (furniture, many toys) and can mark obstacles on the map, with adjustable sensitivity. Multiple reviews agree it struggles most with low, thin cables/wires and very small clutter, where bumps or run-overs can happen.

Product 2: Eufy S2 Omni
4.1

Obstacle avoidance is useful but not flawless; some reviewers saw excellent avoidance, while independent testing found everyday clutter still gets pushed.

Odor control
Product 1: Roborock QV 35A Robot Vacuum...
3.2

Odor risk centers on the dirty water tank and slow pad drying: several reviewers recommend emptying and rinsing the dirty tank frequently (some even add disinfectant) to prevent foul smells. Neglecting this step is repeatedly called out as a downside.

Product 2: Eufy S2 Omni
4.3

Odor control is polarizing: the dock sanitation and fragrance can help, but some reviewers found the scent too weak to matter.

Overall cleaning convenience
Product 1: Roborock QV 35A Robot Vacuum...

Storage footprint is mixed: the station is narrow or compact to some reviewers, but taller and more wall-space-hungry to another.

Streaking / Residue
Product 1: Roborock QV 35A Robot Vacuum...
3.6

A few tests show smearing can happen on muddy prints or when pads carry dirty liquid before they are washed. Users note that extra passes, better floor-direction settings, or more frequent pad washing can reduce residue.

Product 2: Eufy S2 Omni
4.7

Streaking and residue performance is strong in most hard-floor tests, with reviewers repeatedly reporting no visible streaks, residue, or smearing.

Stuck resistance
Product 1: Roborock QV 35A Robot Vacuum...
3.8

The robot generally navigates efficiently, but low cables/wires and certain tight areas can still cause issues. Reviewers recommend picking up clutter and using no-go zones, and the app may flag problem spots over time.

Product 2: Eufy S2 Omni
4.4

Stuck resistance is positive on thresholds, rugs, and obstacles, though not every obstacle-avoidance test was flawless.

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: Eufy S2 Omni
4.8

Suction and airflow are major strengths, with 30,000 Pa, 100 air watts, and sustained airflow repeatedly highlighted.

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: Eufy S2 Omni
3.7

Heavy-duty suitability is good but not absolute; it can tackle demanding rugs and heavy use, but sustained max boost and deep shag can still be caveats.

Support and Reliability
Product 1: Roborock QV 35A Robot Vacuum...
3.9

Customer support is described as friendly and ultimately helpful, but slower than ideal, with back-and-forth email and multi-week resolution mentioned. Day-to-day reliability is generally praised, with the usual caveats around occasional snags and maintenance.

Product 2: Eufy S2 Omni
3.3

Support and reliability are mixed: firmware updates were active, but a preorder recall and short warranty caveat reduce confidence.

Under-Furniture Pickup
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: Eufy S2 Omni
4.6

Under-furniture pickup is positive, with reviewers saying it fits under most furniture and cleaned under beds that prior robots missed.

Value-for-money

Product 2: Eufy S2 Omni
3.4

Value-for-money is mixed: the S2 is premium and capable, but reviewers questioned whether it justifies its price over Eufy's cheaper models or other flagships.

Versatility

Product 2: Eufy S2 Omni

Versatility is strong across vacuuming, mopping, carpet adaptation, hard floors, thresholds, schedules, and multi-room cleaning.

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: Eufy S2 Omni
4.1

Water tank usability is mostly good, with clear clean-water visibility and large reservoirs, though dirty tanks can develop odor without rinsing.
