Low-profile design
Product 1: Shark Matrix Self Empty Robot...
4.2

The robot has an average-to-low profile that fits under many pieces of furniture, but it is not the thinnest option in the category.

Product 2: Roborock Qrevo Edge S5A Robot...
4.3

The robot is relatively slim for a LiDAR-top model (around 4 inches / ~9.8 cm), helping it fit under more furniture than many competitors. It is still taller than ultra-thin flagships that remove the top LiDAR turret.

Maintenance requirements
Product 1: Shark Matrix Self Empty Robot...
4.0

Maintenance needs are generally modest with the self-empty base, but owners should expect regular brush/side-brush cleaning and filter care (including the dock filter) to keep performance consistent.

Product 2: Roborock Qrevo Edge S5A Robot...
4.4

Maintenance is largely hands off thanks to the auto-empty and mop-wash dock, plus reduced hair tangling. Users still need to replace bags, rinse/clean the dock tray occasionally, and maintain filters and pads.

Map and Path Efficiency (Robot Vacuums)
Product 1: Shark Matrix Self Empty Robot...
4.3

LiDAR mapping and pathing are frequently praised for speed and efficiency, often completing coverage faster than some rivals; complex obstacle avoidance and precision edge behavior are weaker than top-tier robots.

Product 2: Roborock Qrevo Edge S5A Robot...
4.6

LiDAR-based navigation earns strong marks for fast, accurate mapping and efficient room coverage. Multi-floor support and reliable pathing are repeatedly highlighted as core strengths.

Mop lifting system
Product 1: Shark Matrix Self Empty Robot...
No score yet
Product 2: Roborock Qrevo Edge S5A Robot...

Noise level
Product 1: Shark Matrix Self Empty Robot...
3.4

Cleaning noise is typically acceptable but not quiet; multiple reviewers describe it as louder than expected or note a loud brush/roller sound, especially compared with quieter competitors.

Product 2: Roborock Qrevo Edge S5A Robot...
4.5

Generally quieter than many competitors; peak loudness is cited around 70 dB on higher suction, and real-home testing reports low disruption (pets barely reacting).

Obstacle Avoidance (Robot)
Product 1: Shark Matrix Self Empty Robot...
2.1

Object/obstacle avoidance is a clear weak point; without a camera-based system, it may bump into or run over low obstacles, so no-go zones and floor prep are important.

Product 2: Roborock Qrevo Edge S5A Robot...
3.3

Obstacle avoidance is the most mixed area: some users see graceful navigation around common items, while multiple controlled tests show it can run over cables and miss smaller or low objects, especially on carpet. Camera-equipped models are consistently reported as better here.

Odor control
Product 1: Shark Matrix Self Empty Robot...
No score yet
Product 2: Roborock Qrevo Edge S5A Robot...
4.8

Hot-water washing plus hot/warm air drying helps keep mop pads fresh, and at least one real-home review explicitly reports no lingering smells after repeated runs.

Ongoing ownership costs (bags, filters, batteries)
Product 1: Shark Matrix Self Empty Robot...
4.5

Ongoing costs tend to be lower than bagged self-empty systems because the dock is commonly described as bagless; filter maintenance remains the primary recurring expense and upkeep.

Product 2: Roborock Qrevo Edge S5A Robot...
4.2

Consumables are typical for an auto-empty robot: dust bags and periodic filter cleaning/replacement. Reported bag life of 30–60 days (or 2–3 months) helps keep ongoing costs manageable, but you may also buy cleaning solution since it is manually dosed.

Overall opinion
Product 1: Shark Matrix Self Empty Robot...
4.1

Overall sentiment is mostly positive, driven by strong cleaning and fast mapping, with the main negatives clustering around object avoidance, edge performance variability, app polish, and noise during emptying.

Product 2: Roborock Qrevo Edge S5A Robot...
No score yet
Pet-Ready Features
Product 1: Shark Matrix Self Empty Robot...

Product 1: Shark Matrix Self Empty Robot...
No score yet
Product 2: Roborock Qrevo Edge S5A Robot...
4.7

Measured low-suction runtime and coverage are impressive in testing, with the robot covering roughly 3,947 sq ft before reaching 0% battery, which is above average. Measured max-suction runtime and coverage are weaker in testing, with roughly 513 sq ft covered before depletion, which is below average. Expect significantly better results on mixed or lower suction settings.

Self-cleaning cycle
Product 1: Shark Matrix Self Empty Robot...
No score yet
Product 2: Roborock Qrevo Edge S5A Robot...
4.6

The dock automates mop washing, pad drying, water refills, and in some cases self-cleaning of the base tray. Reviews generally find these cycles effective and appreciate the reduced hands-on maintenance.

Solution / Liquid system
Product 1: Shark Matrix Self Empty Robot...
No score yet
Product 2: Roborock Qrevo Edge S5A Robot...

Mopping is typically reported as streak free on hard flooring, but heavy muddy messes can smear on an initial pass before pad washing and follow-up cleaning improves the result.

Stuck resistance
Product 1: Shark Matrix Self Empty Robot...
4.2

Navigation generally avoids getting stuck in open layouts, but multiple reviewers still report occasional hang-ups on cords, low furniture, or clutter when floors are not prepped.

Product 2: Roborock Qrevo Edge S5A Robot...
3.4

Most day-to-day runs are described as smooth with few stops, but the robot can still get caught by cables or a sock in some tests. Lack of chassis lift also limits its ability to self-recover on tall thresholds.

Suction and Airflow
Product 1: Shark Matrix Self Empty Robot...
4.6

Across tests and hands-on reviews, suction and airflow are consistently described as above average, delivering strong carpet deep-clean results and excellent crevice performance; a few notes mention harder edge or stress scenarios rather than raw suction limits.

Product 2: Roborock Qrevo Edge S5A Robot...
4.4

Strong rated suction (up to 18,500 Pa) and consistently good real-world pickup, even when lab airflow/pressure measures slightly below average. Overall cleaning results on hard floors and rugs are described as above average for the price tier.

Suitability for small spaces
Product 1: Shark Matrix Self Empty Robot...
No score yet
Product 2: Roborock Qrevo Edge S5A Robot...

4.2

Under-furniture pickup is generally good thanks to a fairly low robot profile, though clearance still depends on furniture height and layout.

Product 2: Roborock Qrevo Edge S5A Robot...
4.3

Its relatively low height helps it reach under furniture and low cabinetry where many robots miss dust. At least one real-home test highlights under-cabinet cleaning as a major day-to-day benefit.

Water tank
Product 1: Shark Matrix Self Empty Robot...
No score yet
Product 2: Roborock Qrevo Edge S5A Robot...
4.5

The clean/dirty water tank setup is a key convenience feature; reviewers cite large tanks (around 4 L clean and ~3.5 L dirty in one real-home test) and automatic onboard refills. This enables multiple full clean-and-mop sessions before needing attention.
